Spark and Uniswap launch a $150M stablecoin FX layer on Uniswap v4 targeting banks, fintechs, and payment providers.

Spark is establishing a "liquidity foundation" for the new pool by migrating $150 million from its USDS ecosystem to Uniswap v4.

The protocols are building shared liquidity and trading infrastructure for a future with hundreds of competing digital currencies on blockchain rails.
