Attrace is a referral protocol for the web3 ecosystem. It allows users to unlock the value of word-of-mouth recommendations by offering referral rewards in tokens on platforms like Uniswap and Sushiswap. The protocol is secured by the ATTR token, which is used for staking and earning rewards. With Attrace, individuals can earn rewards for referring others to crypto or NFT projects based on the real on-chain value created through their referrals.
