Circle and edgeX said edgeX will become the flagship perpetuals venue on Arc when the mainnet launches on September 16, introducing 24/7 foreign exchange trading from day one. The rollout will start with a USD/JPY perpetual contract and more than 150 perpetual markets spanning U.S. stocks, commodities, and crypto assets, all using Arc-native USDC for margin and settlement. The companies said the partnership is aimed at expanding Arc’s on-chain FX and global asset trading market. Arc is Circle’s Layer 1 blockchain for stablecoin finance, featuring a built-in FX engine, an institutional-grade RFQ system, and 24/7 on-chain PvP settlement with USDC as the native gas token. edgeX, which said it has processed more than $900 billion in cumulative trading volume, plans to add more mainstream FX pairs over time and explore non-USD stablecoin margin and on-chain FX spot markets.
