Score history
This rating is re-checked every month. A point is recorded for every check, so a flat line means we looked and nothing moved. Hover anywhere on the chart to see what moved that month, and by how much.
The Problem
DeFi lending markets suffer from fragmented liquidity, volatile borrow rates tied to utilization, and idle stablecoin capital left undeployed across chains and protocols.
The Solution
Spark borrows from Sky's deep stablecoin reserves and deploys capital automatically via the SLL, delivering governance-set predictable borrow rates and deep, stable liquidity across multiple chains.
Why it Matters
Unique combination of a battle-tested Aave V3 lending core with a fully automated, rate-limited liquidity layer backed by one of DeFi's largest stablecoin reserves (~$6.5B).
