Spark adds RLUSD/USDS pool to FX Layer with Sentora

October 27, 2026

Spark expanded its FX Layer with an RLUSD/USDS pool, with Spark funding both sides of the pair so the stablecoin issuer gets trading liquidity without committing its own capital. Sentora supported the deployment.

RLUSD joins USDT and PYUSD on the FX Layer, which uses USDS as a common liquidity base to connect a network of stablecoins.
Reporting around the integration points to a $375M RLUSD deployment, including a $250M Sentora-curated Morpho vault and roughly $50M allocated to the RLUSD/USDS market on Uniswap v4.
Cumulative FX Layer volume has surpassed $12B in less than three months since launch.
