Spark Brings $150M Stablecoin Liquidity to Uniswap v4

Spark deployed approximately $150 million across two Uniswap v4 pools on Ethereum, while its DualPool hook and Shared Liquidity Layer are planned for later phases.

Decentralized finance (DeFi) protocol Spark has deployed approximately $150 million in stablecoin liquidity across two Uniswap v4 pools on Ethereum as part of a collaboration aimed at creating shared liquidity and exchange infrastructure for stablecoin issuers.

A Spark spokesperson told Cointelegraph that the initial deployment is live in two pools pairing USDS with PayPal USD (PYUSD) and USDT, with USDS serving as the foundation. Spark described the deployment as one of the largest automated market maker (AMM) liquidity migrations in DeFi.

“These pools represent the initial deployment of approximately $150 million of liquidity and establish the first phase of the Stablecoin FX Layer,” the spokesperson said. “This initial deployment focuses on bootstrapping shared liquidity on Uniswap v4.”

Earlier this month, Standard Chartered identified Uniswap as a potential beneficiary of tokenized assets moving into DeFi. It forecast that total assets held in DeFi could reach $2.7 trillion by 2030, with Uniswap potentially emerging as a liquidity venue for the growing market.

The deployment announced Thursday lays the groundwork for a planned programmable liquidity system that could reduce the need for banks, financial technology firms and stablecoin issuers to build separate liquidity networks while testing whether Uniswap can make onchain capital more efficient without weakening market depth.

Spark said it plans to introduce its Shared Liquidity Layer and DualPool hook in subsequent phases using Uniswap v4's programmable architecture to coordinate how liquidity is distributed across stablecoin markets.

A liquidity hook enables protocols to seamlessly integrate with platforms for capital access and developing yield and trading strategies.

Spark said a hook is intended to allow capital not immediately needed for trades to be deployed into governance-approved products, liquidity venues and yield-generating strategies.

The implementation of the DualPool hook will go through a separate security review, testing and production-readiness process before deployment. The first phase uses standard Uniswap v4 pools rather than the planned programmable framework.

Spark said the planned framework is intended to give future stablecoin issuers access to shared liquidity rather than requiring them to individually bootstrap pools, coordinate market makers and manage inventory across different venues.

The spokesperson told Cointelegraph that Spark is working with additional partners across the stablecoin ecosystem but is not yet ready to disclose those integrations.

In a June 15 note to clients, StanChart's bank's head of digital assets research, Geoff Kendrick, said that tokenized treasures, equities, bonds and other assets could bring more trading activity and liquidity to decentralized exchanges as their DeFi use expands.

This new $150 million migration offers a more immediate test of StanChart's infrastructure thesis, though it involves stablecoins rather than tokenized securities.

The migration also follows Uniswap’s push into institutional tokenized-asset trading. On Feb. 12, BlackRock said it would bring its $2.1 billion tokenized Treasury fund , BUIDL, to Uniswap, allowing eligible institutional investors and market makers to trade the security through decentralized infrastructure.
