RLUSD Joins Spark's Stablecoin FX Layer on Uniswap V4

Ripple's RLUSD stablecoin has joined Spark's Stablecoin FX Layer on Uniswap V4, expanding the shared-liquidity stablecoin network. The network now includes PYUSD, USDT, and USDS.

During its first week, the RLUSD/USDS pair processed over $600M in volume, adding significant activity to a network that has already accumulated more than $10B in cumulative volume since June 25th, 2026.

The Stablecoin FX Layer pairs route swaps through shared liquidity, allowing each new issuer to bring flow into the pool alongside existing stablecoins. For Spark holders, sustained routing volume is crucial for protocol fees and liquidity depth, rather than just launch-week activity.
