There are many DeFi platforms, please visit this link https://coinmarketcap.com/view/defi/
by the way i am currently reviewing the DeFi platform made by Digichain, Digichain is a new project and has a market cap of under $1 million usd, I think this project can compete with other projects because the team will make blockchain 4.0 which has better speed than other blockchains. (NFA)
Here's an overview of the best crypto expected to do well in the DeFi sector.
Battle Infinity (IBAT) – Overall Best DeFi Coin Project in 2022
TamaDoge – Best Young Crypto Project
Lucky Block (LBLOCK) – Best DeFi Coin for Passive Income
DeFi Coin (DEFC) – Best DeFi Coin for Staking
Cosmos (ATOM) – Crypto Project Connecting Blockchains
UniSwap (UNI) – Best DeFi Coin by Market Cap
Cardano (ADA) – Best DeFi Coin for Innovation and Security
Decentraland (MANA) – Best DeFi Coin for Metaverse Enthusiasts.
Depends on what ticks your fancy. One of the most important things to consider after deciding on a DeFi token is the APYs available to best maximise one's investment. I use Trofi exchange to get the best APRs
