According to Foresight News, the all-chain liquidity asset protocol StakeStone has introduced its first liquidity index Bitcoin, named SBTC (StakeStone BTC), and has opened an early deposit channel. The team explained that SBTC, as a liquidity index BTC, aims to leverage the native redemption liquidity of custodial BTC to build an all-chain liquidity BTC asset. This initiative addresses the current issue of liquidity fragmentation faced by many BTC derivative assets and expands the application of BTC assets within the EVM ecosystem and other blockchain networks.
