## Source summary

CoinDesk reports that Spark moved about $150 million into Uniswap v4 pools pairing USDS with USDT and PYUSD. CEO Sam MacPherson says the stablecoin-to-stablecoin layer handled roughly 30% of that segment's Uniswap volume and about $1.5 billion of routing in its first 30 days; these figures are management claims, not independently audited performance.

## Why it matters

As payment companies and technology platforms issue more separate dollar tokens, liquidity fragmentation can raise conversion slippage and working-capital needs across stablecoin payment routes. Spark is testing whether shared FX liquidity can connect those tokens, but the article does not establish live cross-border payment adoption or customer savings.

## Key numbers

- **Liquidity moved into USDS pairs:** about $150 million
- **Stablecoin swap volume routed in the first 30 days:** about $1.5 billion
- **Share of Uniswap stablecoin-to-stablecoin volume claimed by management:** about 30%
