Spark and Uniswap have launched a dedicated stablecoin swap pool on Ethereum called FX Layer, seeded with $150M in liquidity pulled from three major stablecoins: USDS, USDT, and PYUSD.
How FX Layer actually works
FX Layer leverages Uniswap’s concentrated liquidity model, which lets liquidity providers focus their capital within narrow price ranges. For stablecoins that should always trade near $1.00, this is particularly powerful.
Instead of spreading liquidity across a wide price spectrum, concentrated liquidity allows providers to park their capital in a tight band, say between $0.99 and $1.01. The result is dramatically deeper liquidity exactly where it matters.
The $150M seed comes from three stablecoins with very different backers. USDS is the flagship stablecoin of the Sky ecosystem, formerly known as MakerDAO. USDT is Tether’s juggernaut that dominates global stablecoin volume. PYUSD is PayPal’s entry into the space, backed by one of the largest payment companies on earth.
