According to CoinMeta, Monerium, Frax, and Capa have launched a EURe / frxUSD fund pool on Polygon's Uniswap v3, supporting the exchange between euros and US dollars stablecoins. Eligible Monerium customers can transfer funds through SEPA and, after receiving EURe in their associated wallets, exchange it for frxUSDCapa to support related liquidity, payment, and foreign exchange trading activities.
