Spark Moves $150M to Uniswap v4 for Stablecoin Swaps

• Spark moved $150M in liquidity to Uniswap v4 pools.
• FX Layer aims to reduce slippage between major stablecoins.
• DualPool hook and Shared Liquidity Layer are planned later.

The Spark Uniswap partnership is bringing $150 million in stablecoin liquidity to Uniswap v4 on Ethereum. The move marks one of DeFi’s largest liquidity migrations and supports Spark’s plan to build shared stablecoin swap infrastructure. The first deployment covers two Uniswap v4 pools, while more features are expected in later phases.

Spark Uniswap Migration Builds Stablecoin Liquidity Base

The Spark Uniswap rollout begins with about $150 million deployed across two Ethereum pools. Spark said the capital comes from its USDS ecosystem and will support stablecoin swaps.

The system is designed to serve USDS, USDT, and PYUSD liquidity. USDS is issued by Sky, formerly MakerDAO, and follows DAI as its successor.

Uniswap said Spark is building stablecoin infrastructure on its protocol. The liquidity will later move to Spark’s DualPool hook.

That feature is expected to help users earn from both active and idle assets. However, timing details were not included in the initial update.

Spark Uniswap FX Layer Targets Institutional Stablecoin Use

The Spark Uniswap project also introduces the FX Layer. This system aims to help institutions swap between dollar-pegged tokens with low slippage.

Instead of each issuer building separate liquidity, the FX Layer creates shared infrastructure. Banks, fintechs, and payment firms could connect to the same base system.

Spark will coordinate liquidity allocation and governance. Meanwhile, Uniswap provides the programmable AMM design through Uniswap v4.

Spark CEO Sam MacPherson said the next stablecoin phase depends on shared infrastructure. He said stablecoins will need systems that let many issuers operate together globally.

The launch comes as stablecoin demand grows after the GENIUS Act. Still, experts warn that stablecoin adoption depends on smooth conversion between different dollar tokens.

The Spark Uniswap plan remains phased. The DualPool hook and Shared Liquidity Layer will arrive after the first liquidity deployment.
