"For the sake of security and transparency, we obsolsted a centralized database for saving address binding information and switched to a smart contract on Ethereum mainnet called LRxAirdropAddressBinding. This smart contract has been deployed at 0xbf78b6e180ba2d1404c92fc546cbc9233f616c42 and its code has been verified."

I've never heard of binding addresses and needing to create smart contracts for an airdrop, it would be good to understand more.

"Loopring is not only a protocol but also a decentralized automated execution system that trades across the crypto-token exchanges, shielding users from counterparty risk and reducing the cost of trading. By pooling the liquidity of cryptocurrencies, we are building the financial system of the future."

I haven't bound my address, but will do later if safe / worthwhile to do so.

Here is my referral link anyway if you want to sign up: https://noshortlink/t6fZNg.

"You do not have to rush, the very first airdrop wont’ happen before May 15th 2018."

Guess I won't be rushing then
