Spark deployed about $150 million across two Uniswap v4 stablecoin pools on Ethereum, with programmable liquidity features planned for a later phase.

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.
