Spark: RLUSD Joins Stablecoin FX Layer on Uniswap V4 - 10 Sep 2026
Ripple's RLUSD has joined Spark's Stablecoin FX Layer on Uniswap V4, expanding the shared-liquidity stablecoin network alongside PYUSD, USDT and USDS. The RLUSD/USDS pair processed over $600M in volume during its first week, adding measurable activity to a network that has already accumulated more than $10B in cumulative volume.The first-week figure gives a concrete adoption signal rather than a projection. Stablecoin FX Layer pairs route swaps through shared liquidity, so each new issuer adds flow that existing participants can access, and RLUSD brings Ripple's distribution into that pool alongside three established stablecoins. For SPK holders, the relevant question is whether usage of the core product continues to compound, since protocol fees and liquidity depth depend on sustained routing volume rather than launch-week activity. The $600M result strengthens the usage thesis, though it reflects an early window and later weeks may differ.RLUSD Expands Liquidity and Distribution Through the Spark Stablecoin FX Layer’s RLUSD joins Sparks Stablecoin FX Layer: the liquidity network that has processed more than $10B in cumulative volume since launching on 25th June 2026.Joining Paypal’s PYUSD and Tethers…
