A3S Protocol is a multi-chain protocol to realize Interaction Abstraction, enabling every users to experience the advanced functions of smart contract in a simpler way. It changes functional smart contracts into A3S smart NFTs, thereby users can freely trade or collect the smart NFTs to get the corresponding functions and realize some complex on chain interactions. A3S Protocol in the first stage build up the architecture of transferable addresses that equips contract addresses with liquidity and integrability.   Steps by steps, We aim to taking ‘Account Abstraction’ further to the next era of ‘Interaction Abstraction’.
