Extended completes migration to Circle’s Arc with USDC and cirBTC collateral

The perpetuals exchange moved approximately $120 million in TVL off Starknet without halting trading, the first step in a partnership with Circle Extended, a decentralized exchange built around perpetual contracts, has fully moved to Arc. Trading is live, with USDC and cirBTC as the accepted collateral. The migration took place on October 22, 2026, at 13:00 UTC. Extended shifted its settlement infrastructure from Starknet to Arc, carrying approximately $120 million in total value locked (TVL) with it. Open positions and orders came along intact. Traders did not need to close out and rebuild their books on the other side. Deposits and withdrawals did pause briefly during the transition. Both have since been restored. The collateral menu changed, though.
