Announcements [ANN] / zkPass Protocol

« on: September 01, 2023, 02:39:23 PM »

A Technical Overview of zkPass Protocol

zkPass, a privacy-preserving protocol for private data verification. It is built on the foundation of Multi-Party Computation (MPC), Zero-Knowledge Proofs (ZKP), and three-party Transport Layer Security (3P-TLS). zkPass provides TransGate, which enables users to selectively and privately validate their data on any HTTPS website to the web3 world.

It can cover various data types such as legal identity, financial records, healthcare information, social interactions, work experience, education and skill certifications, etc. All these types of verifications can be done securely and privately without the need to disclose or upload any sensitive personal data to third parties.

zkPass can be readily incorporated into multiple application scenarios, including composable decentralized identity passes, DeFi lending protocols relying on off-chain credit, privacy-ensured healthcare data marketplaces, and dating apps featuring verifiable zkSBTs, etc. Wherever there is a need for trust and privacy, zkPass can provide a solution.

Users control the private Data without leaking sensitive personal information, avoiding unpredictable potential criminal convictions and offenses.

This post gives an overview of zkPass Protocol’s overall architecture and how it works.

Symbols and Definitions

P: Prover (Individuals)

V: Verifier (Business)

S: TLS server

Q: P-initiated query

R: Data replied by S

enc_key: The key of the encrypted data in TLS

mac_key: The MAC key in TLS

t: Digest

Overview Solutions

In the traditional data validation and confirmation process, the Prover submits their information to the Verifier. The Verifier retrieves this data and performs authentication checks in collaboration with the DataSource. Thus, the Verifier serves merely as an intermediary or broker in this model.

Each party faces unique challenges in this scenario: for the Prover, there’s a risk of disclosing excessive personal information; for the DataSource, while it’s a trusted data provider, it’s incapable of offering personalized verification services; and for the Verifier, they’re privy to all the customers’ private data, gaining total access, which presents significant potential risks of data leakage.

We propose a new approach that repositions these three entities, positioning the Prover between the Verifier and the DataSource. Rather than the traditional method, the Prover uses their access token to directly locate and retrieve their data from the DataSource, subsequently generating a Zero-Knowledge Proof (ZKP) for the Verifier to check. This process ensures the Verifier remains unaware of the Prover’s personal information.

In order to implement this structure, we incorporate 3P-TLS, MPC, and IZK technologies.

3P-TLS

Transport Layer Security (TLS) is the secure protocol for HTTPS, supported by almost all Data-Sources. It is a two-party protocol designed for a client/server structure. We have built the 3P-TLS protocol based on the elliptic curve DH protocol and combined it with MPC and Oblivious Transfer (OT) to prevent cheating.

MPC

One challenge we face is that the Prover may forge proof information provided by the DataSource to deceive the Verifier. The solution to this problem is through MPC, where both the Prover and the Verifier hold half of a session MAC key, which is a data integrity key used to maintain data integrity. Since the Prover cannot forge or tamper with information responses provided by the DataSource, it cannot deceive the Verifier. MPC can also prevent the Verifier from knowing any private information about the Prover. During the MPC handshake, there is no encryption key (data confidentiality key) for the Verifier, so it cannot decrypt any data and therefore does not know any private information about the Prover.

IZK

After obtaining information from the DataSource, the Prover needs to prove certain statements of the response in a secure and private manner. We use Zero-Knowledge Proofs (ZKP) to achieve this goal. More specifically, we use interactive commit and prove zero-knowledge proofs (ICP-ZKP) to deal with the large scale of the circuit. The Prover gives the commitment as c = commit(m, r), where m is the message and r is the randomness. Then the Verifier checks that commit(m, r) = c. The commitment does not reveal any information about m, and the Prover can’t find different m’ and r’ (and m’’ and r’’) such that commit(m’, r’) = c and commit(m’’, r’’) = c. During the protocol, the Prover needs to commit its private witness, then prove the input wires and the computation of each gate one by one, and continue to commit the output wires until the final one.

Future Direction

The fields of MPC and ZK related technologies are constantly evolving, with significant advancements being made each year. To ensure the continuous optimization of the zkPass protocol, we are actively staying abreast of the latest technologies. Here are some noteworthy references that we are considering: [FNO14], [NNOB11], [HK20], [HYDK22], [ADST21], [BDOZ10], [FKL+21], [DIO20], [JKO13], [GAZ+21].

OT: Oblivious Transfer

Traditional OT protocols like IKNP/KOS15, which we currently use, require a security parameter (𝑘) bits of communication for each OT. However, we propose building a new maliciously secure OT extension based on VOLE that only needs (log 𝑘) bits. For any (𝑛), this improvement comes at the expense of requiring (2𝑛) times the computation.

GC: Garbled Circuits

Existing GC evaluation methods such as [ZRE14] and [KS08] evaluate GC functions gate-by-gate using encrypted truth tables. The GC evaluator decrypts the corresponding output label based on input labels. However, interactive protocols offer more sophisticated techniques. For example, we can expose a (masked) private value to a party, allowing them to perform local computation and feed the resulting cleartext value back into the MPC.

IZK (Interactive Zero-Knowledge) Protocols

VOLE-based IZK ([WYKW20]/[YSWW21]) suffers from high communication overhead, often linear to the circuit size. We are constructing new ZK protocols with communication sublinear to the circuit size while maintaining a similar level of computational efficiency.

Announcements [ANN] / Kakarot

Kakarot: an intro to the first modular zkEVM



TL;DR: Kakarot is a type 3 (soon-to-be type 2.5) zkEVM, built on top of the CairoVM. The project, which began in October 2022, has several goals in mind: open-source from day one, welcoming contributions, and most ambitiously, creating a zkEVM in less than 10,000 lines of code. We achieved this goal in just six months. We’ll release a testnet at the end of summer 2023.

A glossary is available at the end of the article for context on EVM, zkRollups and zkEVM.

An Incomplete Primer on the CairoVM

The CairoVM is a virtual machine that enables provable execution. It serves as the foundation for Starknet, a general-purpose Layer 2 (L2) validity rollup in the Ethereum ecosystem. The CairoVM’s ability to represent execution as polynomials allows every transaction on Starknet to be proven using STARKs. This necessitates developers building decentralised applications (dApps) in Cairo, the associated programming language.

In the words of the team behind Cairo, Lior Goldberg and Shahar Papini and Michael Riabzev:

We present Cairo, a practically efficient Turing-complete STARK-friendly CPU architecture. We describe a single set of polynomial equations for the statement that the execution of a program on this architecture is valid. Given a statement one wishes to prove, Cairo allows writing a program that describes that statement, instead of writing a set of polynomial equations.

Takeaway: Programs written in Cairo are provable, which enables a game-changing advantage: writing provable programs in a high-level language. As a result, developers looking to leverage the scalability property of zero-knowledge cryptography no longer need to write circuits.

So, would rewriting the Ethereum Virtual Machine (EVM) in Cairo result in a zkEVM?

The idea was simple: the EVM is a mature, well-defined VM architecture. 142 opcodes, 9 precompiles, and a democratic process to update these opcodes or precompiles. Should one build it in Cairo, would one get a zkEVM “for free”, i.e. obtain the scaling property of zero-knowledge as a direct consequence? Spoiler alert, yes.

From there, the idea gained traction in the Starknet community. Abdel, the lead of Starkware’s exploration team and part of the core Ethereum developer team, started implementing it in October 2022. Around the same time, the open-source builder community of Starknet — gathered together with Onlydust’s help — began a similar project in parallel. The former absorbed the latter during StarknetCC in Lisbon.

By the End of 2022, Kakarot Had 100% of EVM Opcodes Implemented.

A hacker house in Lisbon, one week of dedicated work, and about ten people building a zkEVM. The Kakarot core team was born. We realized that this was feasible and powerful. A naive implementation of a zkEVM that fit in less than 5,000 lines of code. No circuits, no polynomials. Just high-level, expressive code.

With the help of the Starknet Foundation and Onlydust, we embarked on this adventure. Our values were open-source, open contributions, and community-driven technical strategy. Clément and I led and coordinated this effort. Today, Kakarot has more than 40 unique contributors. While Kakarot is incorporating to crystallise the effort around building a production-grade zkEVM, our values endure: open-source forever and open for outside contributions

As of May 2023, Kakarot has achieved 100% bytecode equivalence (equivalent to type 3 zkEVM) and implemented 8 out of 9 EVM precompiles. It will soon have all nine of them, thus reaching type 2.5, as per Vitalik’s typology. As a result, dApps written in Solidity or any other EVM-supported language can be deployed onto Kakarot without requiring any modifications to the existing code.

What’s Next? A Two-Fold Bet: Bring the EVM to Starknet and Build a zkEVM-Rollup-as-a-Service Product

When we analysed the market, we noticed that compared to other zkEVMs, Kakarot is an underdog — a team of fewer than 10 people with a significantly smaller budget and brand. Deploying as a general-purpose zkEVM L2 seemed risky. So, what other strategies appeared sound? Bring EVM compatibility to Starknet and leverage fractal scaling.

We strongly believe Cairo will prove to be the best toolbox for zero-knowledge engineering in the coming years. We also believe the EVM will remain the most common layer of abstraction for developers. This is why we’re bringing EVM compatibility to Starknet. Soon, teams will be able to deploy their Solidity dApp on Starknet, through Kakarot.

Moreover, we think app-chains (or app-specific L3s) will emerge sooner than people expect. The traction that the OP stack has been gaining is a good example. By leveraging the modular nature of Kakarot (small and flexible codebase, adaptable to any Cairo chain), we’re empowered to build a zkRollup-as-a-service tool.
One-click: a zkEVM deployed as L3 on top of Starknet for a specific app. EVM environment, low gas, and fast execution. Cryptographic security.

Context & Glossary

EVM (Ethereum Virtual Machine): The EVM is a Turing-complete virtual machine that executes smart contracts on the Ethereum blockchain. It serves as the runtime environment for these contracts, processing the instructions and managing the state of the network. Developers can write smart contracts in languages like Solidity, which are then compiled to EVM bytecode and executed by the virtual machine.
zkRollups: zkRollups are Layer 2 scaling solutions for blockchain networks, particularly Ethereum. They bundle multiple transactions into a single proof, which is then posted on the main chain. By using zero-knowledge proofs, zkRollups enable greater throughput and lower transaction costs while maintaining a high level of security and decentralisation.
zkEVM (Zero-Knowledge Ethereum Virtual Machine): A zkEVM is an EVM implementation that incorporates zero-knowledge proof systems. It allows for the execution of smart contracts with increased scalability (and sometimes privacy) by leveraging cryptography to prove the correctness of transactions.

Announcements [ANN] / Spiral DAO Airdrop!

« on: April 05, 2023, 04:08:26 PM »

Spiral DAO Airdrop!

To kickstart the protocol Spiral DAO will hold a two-phase Airdrop.




Summary

1st Phase — Launching Airdrop: Spiral DAO will airdrop 3%~5% of the initial token supply towards existing Balancer, CRV, FXS, and SDT stakeholders as well as other DeFi users.

To claim the Airdrop visit https://spiral.farm/airdrop on the 8th of April. The time of the start will be different for each category and is specified below starting from 15–00 UTC+0.
Users will receive Spiral DAO’s governance token — Spiral (SPR) token.
Every user from each category will receive the same amount of tokens — 100 SPR.
Only users holding a greater than a certain amount of stated tokens are eligible for the Airdrop.
Only X first users from each category can claim their Airdrop.
The later you redeem the Airdrop — the more you get. After claiming wait and redeem your tokens later to receive up to 50% more.
2nd Phase — Community building Airdrop: Encouraging active members of community participation programs.

Spiral DAO

Spiral DAO is built by experienced farmers for farmers, which means we have thought about all the downsides associated with yield farming, the most prominent of them being highly inflationary reward tokens and complexities that make it harder to access for newcomers. Spiral is here to change that, as well as other inefficiencies existing in yield farming, bribe markets, and VeTokenomics.

Spiral DAO provides a possibility to stake your liquidity into one of the large variety of pools in exchange for its native Coil (COIL) tokens with an additional yield on top. At its launch, Spiral DAO supports Aura and Convex native pools.

COIL tokens can be staked to obtain our main governance token — the Spiral (SPR) token, which represents governance power for all of the Treasury assets and is backed by a growing market share of all the tokens held within the Spiral DAO treasury (USDC/BAL/CRV/FXS/SDT to start).

Spiral DAO employs novel mechanisms to maintain a balanced Treasury exposure by engaging in bribe markets and optimizing them as a side effect.

1st Phase: Launching Airdrop

To encourage adoption, Spiral DAO will airdrop 3–5% of the initial token supply towards existing Balancer, CRV, FXS, and SDT stakeholders as well as other DeFi users. Only users holding a greater than a certain amount of tokens stated below are eligible for the Airdrop.

Airdrop will be allocated to:

42% — CRV/CVX users: vlCVX, veCRV, Convex LP
25% — BAL/AURA users: veBAL, vlAURA, Aura LP
7% — FXS stakeholders: veFXS
3% — SDT stakeholders: veSDT
7.6% — LobsterDAO NFT owners
7.6% — Degenscore Beacon NFT owners
8.6% — Top-1000 DeBank profiles

First come first serve

Users will receive an equal amount of tokens (100 SPR). However, the supply for each category is limited, which is why only the first X users to claim their Airdrop will be eligible. The X for each category is roughly the following:

270 — CRV/CVX stakeholders: 80 — veCRV; 90— vlCVX; 100 — Convex LP
160 — BAL/AURA stakeholders: 45 — veBAL; 50 — vlAURA; 65 — Aura LP
45 — FXS stakeholders
20 — SDT stakeholders
50 — LobsterDAO NFT owners
50 — Degenscore Beacon NFT owners
55 — Top-1000 DeBank profiles

When snapshot??

Yep. It had already been taken.

The later you redeem the Airdrop, the more you can get.

First, you’ll have to claim your Airdrop. By claiming, you confirm you want to be dropped and secure your spot.
After that, you can redeem your tokens right away or later.
The number of tokens you will receive grows linearly in the first three months, so it makes sense to hold longer and redeem later. The total growth will reach 50%. For example:

Initially, you get dropped 100 tokens. After one month, you can redeem around 116.67 tokens. After two months — 133.333. And after three months — 150 tokens.

The idea behind this mechanism is to spread the total Airdrop pressure across those three months and make it a more engaging activity.

Where?

You can claim your Airdrop at https://spiral.farm/airdrop.

When?

On the 8th of April. The time when claiming starts will be different for each category.

Claiming Schedule

15–00 UTC+0 — CRV/CVX stakeholders
16–00 UTC+0 — BAL/AURA, FXS, SDT stakeholders
17–00 UTC+0 — LobsterDAO NFT owners
18–00 UTC+0 — Top-1000 DeBank profiles owners
19–00 UTC+0 — Degenscore Beacon NFT owners

Until the X first users are reached, you can still claim your tokens at any time.

2nd Phase: Community building Airdrop

To enhance Spiral DAO adoption, we are launching a community activity incentivization program. As a result of it, the second phase of the Airdrop will be held.

There are three ways to participate:

1. Complete the crew3 quests. We have built a unique API for this event to track different on-chain activities. Stake, share, boost your yield and get exp.

2. Be an active member of the community and participate in our Discord channel discussions.

Announcements [ANN] / Laminar Markets

« on: October 31, 2022, 02:51:53 PM »

An Introduction To Laminar

Electronic markets are chaotic. Buyers and sellers interact rapidly placing orders, canceling orders and replacing orders in a desperate bid to stay ahead of the market and get the best price possible for their trade. Market participants come in many forms. Retail traders may place trades with patience and a degree of nervousness which sometimes turns into indignation. Systematic strategies consume hoards of market data and attempt to determine price movements. On top of this market makers take both sides of the book and attempt to bring some semblance of liquidity and normalcy to the ensuing stampede.

Centralized electronic markets have now existed for decades. They’ve benefited from years of refinement and have become stalwart in their robustness. Though they trade some of the most liquid and sought after products in the world, we rarely think of major equities electronic markets like Nasdaq or the NYSE as inadequate and unable to keep up.

This is where we come to Decentralized Exchanges ‘DEXs’, specifically order-book DEXs. At a high level these are supposed to operate akin to traditional exchanges.

Unlike a centralized exchange, a DEX, by virtue of being on a blockchain, must adhere to the many constraints and limitations of the chosen protocol — for which there are many. The computational capacity of the protocol is shared with every on-chain program or smart contract you could possibly imagine. You might think the order you’re about to submit to the DEX is the most important thing since the discovery of the Higgs boson — but no one’s going to open up a fast lane for you anytime soon. That blockchain is being shared. Nodes on the network are dealing with everything from folks paying for things online, to little Larry whose high school project is to deploy his own NFT. To compound this issue, protocols typically deal with transactions sequentially. In essence, if the network is busy, transactions are going to take even longer. Sounds challenging? Sure, but here’s where Laminar comes into play…

What is Laminar Flow?

Let’s go on a slight tangent and explain why we call our DEX Laminar. In fluid dynamics, laminar flow occurs when the particles of a fluid travel in smooth paths together, without any disturbance or lateral mixing. Think of it this way — particles can travel together and past one another where they don’t affect other particles in other pathways. Hold this thought as it’ll all make sense shortly…

What is Laminar?

Back to blockchains. The order in which transactions are executed is key. Hence why so many blockchains operate by applying transactions in sequence. One at a time. Carrying out all transactions in sequence without any concurrency ensures the integrity of the blockchain. The drawback of this is that handling transactions in sequence is slow, and if your overall transaction throughput is low, then on-chain programs which require substantial transaction throughput, like an on-chain DEX, will suffer.

With laminar flow, if particles don’t interact with each other, then they can travel in tandem. Similarly, if transactions don’t interact with each other, they can be executed in tandem.

Enter Aptos. Aptos uses Block-STM, a parallel execution engine for smart contracts. At a high level, this technology allows transactions to be executed and validated on multiple threads at once via a mechanism which checks dependencies between them. In a simple sense, if 2 or more transactions don’t affect each other, they can be applied in parallel.

If we were to consider typical transactions that an exchange or DEX deals with, a significant portion of these will not overlap. For example, when canceling orders in the limit order book, or entering orders at different levels of the orderbook. As such, Block-STM is enormously promising for building a resilient DEX.

Let’s run through a couple of Laminar’s key features:

Key Features

1. Parallelised cancels

As mentioned Laminar will use a core, innovative feature of Aptos called Block-STM to allow order cancels to be parallelized where possible, increasing the overall throughput of the DEX and reducing the need for market makers to spam cancel requests. With any participant, there will always be some variability in the time it takes to submit requests. Given that cancellations and other non dependent requests can be executed in parallel in the same block, the potential drawbacks of latency variability are reduced. A plus for market makers and more importantly, for liquidity.

2. Delayed Orders

In order to attract retail, users will be able to benefit from reduced taker fees by allowing their orders to rest on-chain for a short period of time. These orders will sit in the event queue for N blocks prior to crossing the book. Market makers here will be able to specify that a passive order (non delayed) will trade more aggressively against delayed orders, knowing these orders aren’t an HFT bot sniping them.

This gives the users a choice to evaluate the trade off between speed and cost, which will aid Laminar in drawing in users willing to sacrifice speed for lower trading costs, incentivising market makers to quote tighter spreads.

So, keeping it simple, our users will get lower taker fees by allowing their orders to rest on-chain for a short period of time, and market makers can specify that a passive order will trade more aggressively against delayed orders, providing better prices to most users.

3. Interface through SDK, UI or API

Laminar is for everyone, and we mean everyone. The DEX is completely decentralized and will always remain that way but we recognise that different users prefer to interact with the DEX in various ways. For this reason, we’ll offer a number of interfaces

*  SDK

The lowest level method of interacting with the on-chain program, the SDK offers developers the ability to get up and running quickly to interact with nodes and call on-chain commands directly. The SDK will be available in both Rust and Python.

*  UI

The Laminar Team will deploy an intuitive web based UI for point and click traders who gravitate towards the user friendliness of point and click trading. The UI will come complete with charts and real-time order book graphics similar to centralized crypto exchanges.

*  API

We’ll offer developers a REST and Websocket interface to programmatically interact with the DEX. If you’re integrating Laminar with your trading platform or have a systematic strategy you’d like to deploy and get trading swiftly — our APIs are here for you.

We hope you enjoyed a gentle introduction to Laminar. We’re all hard at work, but will be diving deeper into some of the details in upcoming posts, so follow us

Sei Network — the deepest liquidity in the Cosmos

The first orderbook-specific blockchain.

Intro to Orderbooks

Orderbook models continue to reign supreme across all large centralized exchanges, both in traditional finance and crypto. They’ve been proven time and time again to be reliable, fast and capital efficient. However, bringing an orderbook on-chain is immensely difficult. Teams need to deal with high transaction costs, slow trade execution, and inaccurate pricing among other obstacles.

There have only been a select few working implementations of orderbooks on-chain thus far. Each one deals with clear tradeoffs, balancing between speed, efficiency, and reliability.

The Significance of On-chain

Off-chain order books have historically dominated perpetual and spot trading on venues like FTX, Binance, and Coinbase. Having been built on robust web2 infrastructure, centralized exchanges have near-zero transaction costs and near-instant order executions. The main drawbacks of off-chain orderbooks are their centralized nature and increased regulatory exposure.

On the other hand, on-chain orderbooks can be decentralized and trustless, but frequently hindered by network congestion, high transaction costs, and slower execution. This means that most on-chain orderbooks are only as efficient and capable as the chains they are built on.

Sei is a layer 1 blockchain purpose-built for an orderbook. The parameters of the chain are perfectly form-fit to match exactly what an orderbook needs. Sei prioritizes reliability, security and high throughput above all else, enabling an entirely new echelon of DeFi products. Apps built on Sei benefit from specialized built-in orderbook infrastructure, blazingly fast execution, deep liquidity, and a fully decentralized matching service.

Built using the Cosmos SDK and Tendermint Core, Sei serves as a shared liquidity hub for ultra-high performance DeFi products to be built on top.

Why now?

Orderbook DEXs have been de-risked:

*  dYdX has grown to nearly 25K traders with $800B+ in annualized volume*

*  Serum has built a thriving ecosystem on top of it, comprising a major portion of Solana DeFi

Institutions are taking note:

Large players like FTX and Binance have paved the way for educating institutional players. Over the next few years, DeFi will start to see meaningful institutional order flow try out DEXs for the first time.

Differentiated technology stack:

The Cosmos SDK has been proven and battle tested at scale. Sei can learn from the mistakes of past orderbook implementations and build superior trading infrastructure from scratch.

Dive in with us

Our Seinami Incentivized Testnet is launching in June. Stay tuned for announcements by following Sei on Twitter. What are you waiting for? Jump on and sei hi!

Амбассадорская программа Cosmic Horizon

Cosmic Horizon — это многопользовательская многопользовательская игра в жанре космической торговли и завоевания, разработанная Qwoyn Studios и использующая Cosmos SDK. Cosmic Horizon черпает вдохновение из
приключенческих и стратегических игр 1990-х годов и обновляет устоявшиеся концепции с помощью современного подхода, основанного на  блокчейне. Основные элементы игры состоят из Вселенной  (разделенной на тысячи отдельных секторов) и элементов внутри нее,  а именно: Игроки, Корабли, Планеты (включая специальные планеты) и Порты (включая специальные порты). Игроки будут взаимодействовать с миром и друг с другом, чтобы получать ресурсы и контролировать части вселенной.

COSMIC HORIZON

What is Cosmic Horizon

Cosmic Horizon is a play-and-earn strategy space-trading/conquest MMRPG, developed by Qwoyn Studios and powered by the Cosmos SDK. Cosmic Horizon takes inspiration from adventure and strategy games of the 1990s and updates the established concepts with a modern blockchain-based approach. The core elements of the game consist of the Universe (divided into thousands of individual sectors) and the elements within it, namely: Players, Ships, Planets (including special planets) and Ports (including special ports). Players will interact with the world and one another to gain resources and exert control over sections of the universe.

Cosmos SDK

Our application-specific blockchain is built using the Cosmos SDK, an open-source framework for building multi-asset public Proof-of-Stake (PoS) blockchains and one of the most powerfull tools in the industry.

Community Owned

Cosmic Horizon is not just an experience, it's a community! Using the power of governance you get to decide how to make it an amazing one. You are at the center of this mission!

DAO

One of the most exciting opportunities a blockchain community presents is the formation of a Decentralized autonomous orginization (DAO). Cosmic Horizon enables making a real change in the world!

Announcements [ANN] / Zaru Finance

« on: August 26, 2022, 12:18:32 PM »

Zaru Finance

At Zaru Finance we believe abundance is achievable 

Zaru was created to guide you on the path to building wealth through a suite of tokenized asset strategies (TAS) that amplify, optimize, de-risk, and protect your portfolio.

Web3 is complex and moves rapidly—making it impossible for the average investor to research the landscape while keeping up with their family, hobbies, life, and job. Zaru's focus is to provide passive strategies that are accessible to everyone and simple to understand.

Product Suite (initially launching on the Optimism network):

*  Optimism Ecosystem Index | $OPI

*  Built on Optimism and Set Protocol

*  Featuring top Optimism network tokens including $OP, $SNX, $VELO, $LYRA & more

*  25% of revenue is routed to Optimism public goods funding.

*  Many more coming soon!



Zaru tokenized asset strategies include familiar thematic index products as well as more complex strategies such as those based on factors (momentum, smart beta), direction (leveraged, long/short, inverse), and income (stablecoin bond, delta neutral).

In short, Zaru passive strategies provide risk-reduced exposure to web3 and digital currencies without constantly researching and managing your portfolio.

Zaru DAO

Zaru Finance is a DAO that will be governed by the $RU token. Zaru's founding team is a group of web3 veterans with experience across financial product management, on-chain engineering, growth, and community building.

Join us on the journey to help everyone achieve abundance through the emergence of Web3 and Digital Currency.
