Introduction
AggreLend is a savings-focused DeFi protocol, open-sourced and built on the Solana blockchain (opens in a new tab), where depositors connect a Solana wallet and supply supported tokens, after which the program continuously and automatically routes balances toward the highest available supply-side lending yield across integrated markets so you can hold the assets you prefer while optimization happens quietly on-chain.
🌱 Grow
Deposit, let it build, and let AggreLend handle the routing:
- Earn Yield — Supply tokens and accrue yield that reflects the currently highest lending rate available across supported markets, with optimization handled on-chain.
- Getting Started — Connect a Solana wallet, choose a supported token, and create a position in a single flow.
- Withdraw Anytime — Close your position and withdraw principal plus accrued yield when you’re ready.
Positions are lend-only (no leverage, no liquidation price) and the protocol prefers reliability over brief spikes in quoted APY.

🧠 Principles
The interface shows the APY you earn; rewards from underlying markets are included in the displayed rate; and while there are no protocol performance fees today, any future fee—if introduced—will be reflected directly in the number you see so it remains the number you get; creating a position requires only a small, refundable Solana rent fee of 0.00161 SOL, which is automatically returned on close.
- Supported Markets — A curated set of audited, well-known integrations.
- Risk & Security — No-leverage design, due-diligence posture, and program-level safeguards.
- Jurisdiction & Access — Interface access terms and decentralization notes.
🧑💻 Developers

- API — Endpoint basics and response shapes.
- Program IDs — Mainnet addresses and links.
