Spark moves $150M in stablecoins to Uniswap v4 pools

Spark deployed roughly $150 million in stablecoin liquidity across two Uniswap v4 pools on Ethereum on Thursday, pairing its USDS token with PayPal USD (PYUSD) and USDT. USDS serves as the base asset in both pools.

Spark described the deployment as the first phase of its Stablecoin FX Layer and said the allocation is intended to bootstrap shared liquidity for stablecoin issuers on Uniswap v4. A spokesperson called the migration among the largest automated market maker liquidity moves in DeFi. The funds are held in standard Uniswap v4 pools while Spark develops additional programmable infrastructure.

The company plans to add a Shared Liquidity Layer and a DualPool hook that use Uniswap v4’s programmable features to coordinate how liquidity is distributed across stablecoin markets. The hook is designed to let protocols move capital that is not needed for immediate trades into governance-approved products, other liquidity venues and yield strategies. Spark said the DualPool hook will undergo a separate security review, testing and production-readiness process before it goes live.

Spark said the framework is intended to give new and existing stablecoin issuers access to shared on-chain liquidity so they do not have to bootstrap pools, hire market makers or manage inventory across multiple venues. The company is working with additional partners across the stablecoin ecosystem but declined to name them while integrations continue.

Analysts have identified Uniswap as a potential beneficiary of growing tokenization and on-chain asset activity. One projection cited by market participants estimated total assets held in DeFi could reach $2.7 trillion by 2030 and suggested decentralized exchanges could become major liquidity venues for tokenized assets. Spark’s deployment tests whether consolidating stablecoin liquidity on Uniswap can increase capital efficiency without reducing market depth.

The rollout follows other institutional activity on Uniswap. In February, a tokenized Treasury product became available for trading on Uniswap, allowing eligible institutional investors and market makers to trade the security through decentralized infrastructure. Spark said it used standard Uniswap v4 pools for the initial phase to establish liquidity immediately while completing security audits and production-readiness work for the programmable features.

Spark characterized the $150 million deployment as a foundational phase and said the initiative will proceed through further phases with testing and governance oversight as it integrates with other ecosystem participants.
