acBTC integrates native BTC and ERC-20 BTC, as well as applications for swap, lending and yield generation into a safe, efficient and easy-to-use standard. acBTC represents the underlying value peg; minted and redeemed on-chain via smart contracts. acBTC is backed 1:1 with a basket of ERC-20 BTC assets (also known as a composite BTC basket). AC is an ERC-20 asset, which empowers the community governance of the acBTC ecosystem. AC token holders can participate in the governance system of acBTC applications (acSwap, acLoan). Its goal is to achieve long-term sustainable value, and community governance will be motivated to collectively guide the acBTC ecosystem into the future with reasonable decisions.
