The perpetual contract platform Extended will migrate its settlement to Arc

The perpetual contract trading platform Extended announced that it will migrate its settlement network to Arc, a Layer 1 blockchain built for financial markets by Circle. The migration is scheduled to take place during the week of October 19, 2026, with specific timing to be announced closer to the date, and trading will continue during the migration. Accounts, sub-accounts, positions, orders, transaction history, points, and keys will remain unchanged.

If any sub-account holds USDT or wBTC valued over 1 USD, users must convert or withdraw by 12:00 UTC on October 21, 2026, as these two assets will not exist on Arc. In-app conversion to USDC or cirBTC will be available at a 1:1 ratio, with Extended covering a 0.50% premium and no exchange fees; the premium will be credited within 8 hours after migration. Recharge for these two assets has been closed since 16:00 UTC on the announcement date. ETH will be automatically converted to wETH on Arc at a 1:1 ratio, and USDC will migrate as native USDC.

Recharge and withdrawal are expected to be paused for no more than approximately 2 hours during the migration, while transfers between sub-accounts will remain available. If the relevant assets exceed 1 USD and the deadline is missed, the entire account will be restricted during processing, and the relevant sub-account positions will be liquidated at the mark price at the time of processing without any fees. The Arc mainnet will go live on September 16, 2026, with institutions such as BlackRock, DTCC, ICE, Visa, and Mastercard as its founding validators.
