BitGo Launches Spark Savings for Institutional Stablecoin Yield

Institutional clients can now earn yield on stablecoins through on-chain credit markets without moving assets out of BitGo's regulated custody.

BitGo announced the launch of Spark Savings on June 9, connecting its custodial infrastructure directly to Spark's lending ecosystem. The product lets eligible clients deploy stablecoins into Spark's savings protocol. It supports USDC and USDT. It also supports USDS, the stablecoin from the Sky ecosystem.

The integration was built through a partnership with Narval, which provides the connective tissue between BitGo's infrastructure and Spark's on-chain products.

BitGo held about $104 billion in assets under custody as of its January 2026 NYSE IPO, serving over 1,500 institutional clients.

BitGo CEO Mike Belshe said operational security is central to the firm's strategy for bringing institutional capital into decentralized finance. Spark CEO Sam MacPherson said governance and security frameworks are key for driving adoption.

Spark operates as a sub-DAO of Sky, the protocol formerly known as MakerDAO. The rebranding happened as part of MakerDAO's broader restructuring, which carved the protocol into specialized units handling different functions.

Spark's product suite includes Spark Savings for yield generation and SparkLend for borrowing and lending. The Spark Liquidity Layer handles broader capital efficiency.

USDS ranks as the third-largest stablecoin by market size at about $8.7 billion. Its inclusion alongside USDC and USDT gives institutional clients flexibility to deploy whichever stablecoin fits their existing treasury management approach.

Spark closed May 2026 with about $6.4 billion in its Savings product. That pool now has a direct pipeline from BitGo's custody clients, a development that fits into broader crypto market analysis.
