Spark

Spark is a decentralized finance application built on Ethereum that functions as an onchain capital allocator, borrowing from stablecoin reserves and deploying funds across DeFi protocols, centralized finance venues, and real-world assets. It claims to address fragmented liquidity, unstable yields, and idle stablecoin capital by acting as shared liquidity infrastructure rather than a standalone lending competitor. The protocol packages yield into composable stablecoin products such as sUSDS and sUSDC, targeting users and protocols that want consistent, large-scale stablecoin liquidity.

Spark draws on Sky's stablecoin reserves and allocates capital programmatically across venues, auto-balancing positions based on market conditions while maintaining what it describes as a conservative risk profile. Its lending arm, SparkLend, offers stablecoin loans at rates set by governance rather than fluctuating utilization curves. The SPK token serves a governance function, giving holders the ability to participate in protocol decisions, and it exists within the Ethereum ecosystem with no block production role of its own.

According to the project description, Spark's yield products are explicitly fee-free, meaning users receiving yield through sUSDS and sUSDC are not charged protocol fees for access. Because no fee stream is described in the stored data, standard fee-based measures such as protocol revenue or fee yield are not applicable here. The circulating supply stands at roughly 3.37 billion SPK against a maximum supply of 10 billion, meaning only 33.74 percent of tokens have been issued, with a dilution overhang of approximately 196.41 percent representing the share of supply still to enter circulation relative to what is already circulating.
