Singapore, 23 September 2026: Spark, the allocation intelligence layer that programmatically coordinates capital across on-chain financial markets, has surpassed $12 billion in cumulative trading volume through its Stablecoin FX Layer less than three months after launch. The FX Layer uses USDS as a common liquidity base to connect a growing network of stablecoins, with RLUSD joining USDT and PYUSD as Spark expands the infrastructure supporting exchange liquidity across the stablecoin market.
The expansion is backed by $375 million of RLUSD deployed across Spark’s broader infrastructure, spanning exchange liquidity through the Stablecoin FX Layer on Uniswap, institutional capital allocation through the jointly curated Sentora x Spark RLUSD Morpho vault, and on-chain credit through SparkLend.
“Stablecoins are rapidly becoming core financial infrastructure, but every new asset shouldn’t need to rebuild its liquidity and capital infrastructure from scratch,” said Sam MacPherson, CEO of Spark. “More than $12 billion in volume through the FX Layer demonstrates the demand for shared liquidity infrastructure that connects otherwise separate stablecoin ecosystems. RLUSD is the latest example of how a stablecoin can connect into existing infrastructure and scale across liquidity, capital allocation and credit rather than building each component from zero.”
The deployment spans three areas. $250 million is targeted for institutional capital deployment through the Sentora x Spark RLUSD Morpho vault, jointly curated by Spark and Sentora to support professional, institutional-scale allocation of RLUSD. $50 million will expand exchange liquidity, with approximately $25 million RLUSD paired with $25 million USDS in the RLUSD/USDS market on Uniswap v4, deepening liquidity through Spark’s Stablecoin FX Layer. A further $100 million is has been deployed to support on-chain credit through the SparkLend RLUSD lending market.
“The friction in moving between stablecoins is one of the most important unsolved problems in decentralized finance, and we’re glad to be working alongside Spark and its partners to address it. This is infrastructure the whole market benefits from.” said Anthony Demartino – CEO Sentora
RLUSD has also seen strong early exchange activity, with the RLUSD/USDS market processing more than $600 million in trading volume in its first week. Spark supported USDS pairs accounted for over 50% of Ethereum stable-to-stable volume on Uniswap during August.
The deployment comes as regulated financial institutions move deeper into digital assets. Over the past 18 months, nearly six in ten applications for new bank charters received by the OCC have involved some form of digital-asset activity, with applicants including Ripple, Coinbase and Morgan Stanley Digital.
As more regulated digital dollars enter the market, liquidity risks becoming increasingly fragmented. Building deep bilateral markets between every stablecoin does not scale. Spark’s Stablecoin FX Layer uses USDS, supported by the Sky ecosystem, as a common liquidity base, allowing stablecoins to connect through shared infrastructure rather than requiring dedicated liquidity against every other asset.
RLUSD, PYUSD and USDT connect through USDS markets on Uniswap v4. USDC provides another route: through the USDS/USDC PSM. USDC can be converted 1:1 into USDS without a swap fee, allowing it to connect into the same liquidity network without requiring dedicated USDC markets against each stablecoin.
Spark’s FX Layer also addresses another source of capital inefficiency through Uniswap v4’s DualPool hook, with USDT/USDS providing the first implementation of this model. Liquidity can move between Spark Savings and Uniswap as demand emerges, allowing capital to earn yield when it is not required for trading, while remaining available on demand to support swaps or withdrawals.
“Uniswap is the largest onchain venue for trading stablecoins, with nearly $400 billion in stablecoin swaps so far this year. Hooks allow teams like Spark to customize markets to improve performance for their specific use cases. Our collaboration with Spark is off to an incredible start, with more than $12 billion in trading volume in under three months”. Hayden Adams, Founder & CEO, Uniswap Labs.
More broadly, through the Spark Liquidity Layer, Spark’s Allocation Intelligence can programmatically coordinate capital across approved markets, vaults and liquidity venues within governance-defined parameters. As more FX Layer markets connect into that infrastructure, capital can increasingly be allocated based on where liquidity is being used and demand is emerging.
