StaFi is a leading Liquid Staking infrastructure provider and protocol for PoS chains. Its Liquid Staking as a Service (LSaaS) framework enables developers to create Liquid Staking Tokens (LSTs) and Liquid Re-staking Tokens (LRTs) across ecosystems like ETH, EVM, BTC, Cosmos, TON, and SOL. By issuing rTokens (e.g., rETH, rMATIC, rBNB), StaFi unlocks the liquidity of staked assets, allowing users to earn staking rewards while retaining the flexibility to engage in DeFi. With support for major blockchains such as Ethereum, Solana, Polygon, BNB Chain, and Cosmos, StaFi bridges liquidity and security in Proof-of-Stake networks.
