Suilend is a decentralised lending and borrowing protocol built on the Sui blockchain. It was launched in March 2024 and represents the expansion of the Solend team from the Solana ecosystem to Sui. The protocol provides lending markets where users can deposit cryptocurrencies into liquidity pools to earn interest or use their assets as collateral to borrow other assets.

Suilend incorporates several features to enhance capital efficiency and security, including:

• Risk-Isolated Lending Pools – Users can lend and borrow assets without being exposed to unnecessary risks from other pools.
• Multi-Asset Collateral Support – Borrowers can use multiple assets as collateral, improving flexibility in loan management.
• Liquid Staking Integration – Through its partnership with SpringSui, Suilend enables instant unstaking of SUI tokens, improving liquidity for staked assets.
• Dynamic Interest Rates – Interest rates adjust algorithmically based on supply and demand, optimising yield for lenders while maintaining sustainability for borrowers.

Suilend allows users to engage in decentralised finance (DeFi) activities, primarily focused on lending and borrowing cryptocurrencies. The protocol supports multiple assets, including SUI, USDC, USDT, ETH, and SOL.

Lenders can deposit supported cryptocurrencies into lending pools and earn interest over time. Borrowers can take out loans by providing collateral, gaining access to liquidity without selling their assets. Liquid Staking allows users to stake SUI while still maintaining liquidity through instant unstaking services. The protocol aims to enhance capital efficiency by enabling users to use their idle assets productively while maintaining exposure to the underlying blockchain ecosystem.
