What Is cSOL?
cSOL is a collateral receipt token issued by Solend when users deposit SOL into the Solend lending protocol on Solana. It represents a user’s deposit position and accrues value over time as interest accumulates on the underlying SOL. cSOL can be held, transferred, and used as collateral to borrow other tokens within Solend’s ecosystem.
How cSOL Works
When you deposit SOL into Solend, you receive cSOL in return at the current exchange rate. As borrowers pay interest on their SOL loans, that interest flows back to lenders: the value of cSOL relative to SOL increases gradually over time. When you redeem your cSOL, you receive the original SOL plus the accumulated interest. The exchange rate between cSOL and SOL is stored on-chain and increases monotonically as interest accumulates.
cSOL as Collateral
Within Solend, cSOL can itself be used as collateral to borrow other assets. This allows users to deposit SOL, receive cSOL, and then use that cSOL to borrow stablecoins or other tokens against it. The position is still earning lending interest on the underlying SOL while simultaneously serving as borrowing collateral, making it a capital-efficient structure for active DeFi users.
Risks and Considerations
cSOL carries the smart contract risk of Solend itself. If the Solend protocol is exploited or a liquidation cascade leads to bad debt, the value of cSOL could be affected. Unlike a native SOL position, your SOL is inside a smart contract rather than in your wallet, so standard wallet security does not fully protect the deposited funds. Users should treat Solend as a third-party custodian for the duration of their deposit.
FAQ
cSOL is the interest-bearing receipt token you receive when depositing SOL into Solend. It represents your lending position and accrues value as borrowers pay interest on SOL loans.
Deposit SOL into Solend on solend.finance. You will automatically receive cSOL at the current exchange rate. The cSOL balance in your wallet represents your claim on the deposited SOL plus any interest earned.
No. cSOL represents SOL deposited in Solend’s lending pool, earning interest from borrowers. Staked SOL (like mSOL or jitoSOL) is SOL delegated to validators to earn staking rewards. Both are yield-bearing SOL derivatives but from different mechanisms.
Yes, in principle. cSOL is subject to Solend’s smart contract risk: a protocol exploit or severe liquidation event could result in loss of funds. The underlying SOL interest is also not guaranteed to exceed gas or opportunity costs in all market conditions.
