SparkLend is an on-chain lending market that sits within the Sky (formerly MakerDAO) ecosystem. Users supply crypto to earn interest and borrow other assets against overcollateralized deposits, with the protocol able to source deep stablecoin liquidity from its parent ecosystem. It ranks fifth of fifteen in our DeFi protocols group, scoring 8.08.
How SparkLend works
The model is a pooled money market: suppliers deposit into liquidity pools and earn variable interest, while borrowers post collateral and take loans that must stay overcollateralized. Rates adjust with utilization, and positions that fall below their required collateral ratio can be liquidated. The codebase follows the well-established pooled-lending design common to major money markets.
What is the role of overcollateralization?
Requiring collateral worth more than the loan is what protects suppliers. If prices moved instantly and perfectly, a loan could be fully backed at all times, but they do not, so the extra collateral buffer absorbs slippage and delay during liquidation. When you borrow, that buffer is effectively your safety margin, and a thinner margin means a higher chance of being liquidated during a sharp move. Understanding each asset's collateral factor before borrowing is essential.
What our data shows
Our measurements record about $4.5B in total value locked across 2 chains, with roughly 3.3 years of on-chain history and two audits on record. Endpoint responsiveness was strong in our checks at around 53ms. We did not find a dedicated public status page.
Key risks
- Liquidation risk: volatile collateral can be sold during sharp price moves.
- Oracle risk: loans and liquidations depend on accurate external price feeds.
- Smart-contract risk: audited but not immune to bugs.
- Ecosystem-dependency risk: ties to the Sky ecosystem bring shared benefits and shared exposures, including governance decisions made upstream.
Who should consider it
SparkLend is a reasonable fit for users who want a large, established money market with strong stablecoin depth and a multi-year record, whether supplying for yield or borrowing against blue-chip collateral. It is a weaker fit for users wanting broad multi-chain reach, since our data tracks only two chains, or anyone who prefers fixed rates over variable ones.
We assess scale, audits, track record, chain reach, latency and status transparency. We do not measure interest rates, which vary with utilization; verify them in the app.
