The development of decentralized finance has long lacked deep involvement from Bitcoin. Bitlayer, through its secure and reliable Layer 2 infrastructure, enables BTC holders to seamlessly enter the DeFi world. Lending, trading, stablecoins, liquidity mining... these scenarios that were once dominated by Ethereum will be realized within the Bitcoin ecosystem in the future. Bitlayer is transforming BTC from 'digital gold' into 'liquid blood', driving DeFi into a new stage.
