Referral Protocol for Web3 Assets Attrace is a trustless Referral Protocol operated by Oracles capable of observing and detecting referrals across the blockchain universe. The Referral Protocol empowers “word-of-mouth” marketing for web3 assets in a trustless and decentralized manner, by linking promotions (e.g. referral links) with the on-chain user activity (blockchain transactions). Furthermore it connects communities across various blockchains and platforms within a single ecosystem by supporting the multi-chain and cross chain referral capabilities. In practice the protocol enables crypto and NFT projects to incentivise referrals of their tokens, while rewarding those who contribute to their growth and adoption. The Attrace App is a referral marketplace where anyone can become part of the ecosystem and interact with the protocol, while direct integration and development of other decentralized apps will be possible in future in an open-sourced manner.
