Spark is building a Stablecoin FX Layer on Uniswap v4 to address liquidity fragmentation as banks and fintechs launch their own stablecoins.​

Key developments:

  • Spark migrated $150M in liquidity to Uniswap v4, one of DeFi's largest migrations
  • Initial pools include USDS/PYUSD and USDS/USDT
  • The infrastructure allows stablecoins to access shared liquidity instead of isolated pools
  • Liquidity will move to Spark's new DualPool hook to earn on both active and idle assets

Context: Fidelity recently chose Uniswap as its liquidity layer for $FIDD stablecoin pools.​

The FX Layer aims to create shared infrastructure for the growing number of institutional stablecoins entering the market.​
