Spark

Spark is a decentralized finance application built on Ethereum that describes itself as an onchain capital allocator, meaning it takes stablecoin liquidity and deploys it across DeFi protocols, centralized finance venues, and real-world assets. The project claims to address fragmented liquidity and inconsistent yields in decentralized lending by acting as a large-scale intermediary between capital sources and borrowers. It is aimed at users and protocols that want access to deep stablecoin liquidity or want to earn yield on stablecoins without actively managing allocations.

Spark draws on reserves from the Sky protocol and deploys that capital programmatically across lending markets, including its own SparkLend platform, which offers governance-set interest rates rather than rates that shift with utilization. Yield generated from these deployments is packaged into products such as sUSDS and sUSDC, which are described as composable and fee-free across chains. The SPK token sits within the Ethereum ecosystem and serves a governance function, giving holders a say in protocol parameters, while the circulating supply of roughly 3.33 billion tokens represents about 33.3 percent of the ten-billion maximum supply.

According to the project description, Spark's yield products are explicitly described as fee-free, meaning the protocol does not appear to collect fees from end users in the conventional sense that would create a measurable fee stream for this site to report. The revenue model instead relies on the spread between borrowing costs from Sky's reserves and yields earned from deployed capital, but no specific fee figures are present in the data provided here. The absence of a reported fee stream means fee-based valuation measures commonly tracked on this site are not applicable to Spark in a straightforward way.
