Bitcoin re-staking platform SatLayer announced Wednesday that it will expand the use of bitcoin in decentralized finance to Sui, a fast layer 1 blockchain launched last year. As Sui focuses on fast transaction speeds, SatLayer's integration will enable developers to leverage Bitcoin's $2.10 trillion market size to build DeFi apps that are designed to keep third parties out of transactions in areas such as trading and lending, SatLayer said in a statement.
