In response to the current lack of real transaction requirements on BTC L2, bitSmiley, the BTC native over-collateralized stablecoin protocol, has launched a multi-chain stablecoin plan, which proposes the following two sets of parallel solutions: (1) Support native BTC collateral and casting in multiple chains to disperse BTC liquidity; (2) Launch of the first BTC LPfi protocol. The bitSmiley protocol hopes to release BTC liquidity and benefit more ecosystems through this parallel two-set solution, which can truly and effectively meet the trading needs of users.
