What is Spark?

Spark consists of three main products:

  • Savings: Earn yield on your stablecoin and ETH holdings via Spark Savings vaults.
  • SparkLend: A USDS-centric money market protocol, combining liquidity directly from Sky with vertical integrations across DeFi.
  • Spark Liquidity Layer (SLL): Direct liquidity provision into DeFi markets across networks.

What is Spark's Mission?

Spark was created to solve a structural problem that has existed since the inception of DeFi: fragmented liquidity, unstable yields, and idle stablecoin capital left underutilized across chains and protocols. Despite years of growth, this issue remained unsolved.

Spark operates as a two-sided capital allocator. On the ecosystem side, it borrows from Sky's stablecoin reserves and deploys capital across DeFi, CeFi, and RWAs. This provides deep, consistent liquidity while earning risk-adjusted yield at scale.

On the user side, Spark packages that yield into accessible products like Spark Savings vaults (sUSDS, spUSDC, spUSDT, spETH, and more), giving users seamless access to onchain, programmable income that is diversified, fee-free, and composable.

Rather than competing with other protocols, Spark powers them. It's not just another DeFi app, it is the core liquidity and yield infrastructure layer for onchain finance.
