Acre is a simple bitcoin-in bitcoin-out experience, to compound your bitcoin.
Bitcoin deposits into Acre are first used to mint tBTC (a fully permissionless and decentralized wrapped-bitcoin token) to Ethereum. tBTC is then used to provide economic security to protocols such as bitcoin-L2s, re-staking protocols, lending, and insurance markets across the EVM ecosystem and beyond.
Bitcoin L2s are similar to all other proof-of-stake chains and provide rewards in exchange for economic security and bootstrapping liquidity. These rewards auto-compound into tBTC and are fully-redeemable to mainnet bitcoin.
In the future, Acre may support additional forms of tokenized bitcoin for deposit in addition to the minting and movement of stBTC, the deposit receipt ERC-4626 token for DeFi.
BTC or stBTC can be redeemed for the underlying BTC and associated rewards at any time, however there is a withdrawal delay and fee associated with each transaction. This withdrawal delay is due to pulling the underlying tokenized Bitcoin out of the smart contract and trustlessly redeeming back to the Bitcoin network.
