SatLayer

 

SatLayer is a Bitcoin-focused protocol that uses Bitcoin-backed economic security to support decentralized applications and Bitcoin Validated Services (BVS). The platform allows users to deposit Bitcoin and supported Bitcoin liquid staking tokens into vaults to provide security to participating services and earn eligible rewards.

 

SatLayer connects Bitcoin restakers, developers, and node operators through shared security infrastructure. Its ecosystem supports applications across DeFi, stablecoins, insurance, liquidity, bridges, and other on-chain services. The protocol also has an ecosystem token called SLAY, which supports staking, governance, incentives, and ecosystem participation.
