Uniswap and Spark are developing a shared liquidity network to facilitate trading between stablecoins as the market expands beyond crypto into mainstream finance. The initiative, announced Thursday, aims to create an "FX layer" that efficiently moves liquidity among various issuers while allowing idle capital to earn yield. As a first step, Spark will migrate $150 million in liquidity to Uniswap v4, supporting USDS, USDT, and PYUSD. This comes as banks, fintechs, and payment firms increasingly explore stablecoin issuance, with Citi projecting the market could grow from $300 billion to $4 trillion by 2030. Spark CEO Sam MacPherson emphasized that the key to stablecoin adoption is infrastructure enabling hundreds of issuers to interoperate at global scale.
