The switch is scheduled for the week of October 19, with trading continuing uninterrupted. Users with more than $1 in USDT or wBTC must convert or withdraw their funds by October 21 at 12:00 UTC. USDT and wBTC can be exchanged for USDC or cirBTC at a 0.50% premium. ETH will be converted to wETH, and USDC will become native on Arc. Deposits and withdrawals may be paused for up to two hours. Trading volumes for altcoins may shift as the migration progresses.

ChainCatcher report: The perpetual futures trading platform Extended has announced it will migrate its settlement network to Arc, Circle’s Layer 1 blockchain built for financial markets. The migration is scheduled for the week of October 19, 2026; the exact time will be announced closer to the date. Trading will continue during the migration. Accounts, sub-accounts, positions, orders, history, points, and keys will remain unchanged. Users must convert or withdraw any USDT or wBTC with a value exceeding $1 from their sub-accounts by October 21, 2026, at 12:00 UTC, as these assets will not exist on Arc. Within the app, these assets can be converted 1:1 to USDC or cirBTC at no exchange fee, with Extended covering a 0.50% premium, which will be credited within 8 hours after migration. Deposits of these two assets have been disabled since 16:00 UTC on the day of this announcement. ETH will be automatically converted 1:1 to wETH on Arc, and USDC will migrate as native USDC. Deposits and withdrawals are expected to be paused for no more than approximately 2 hours during migration; transfers between sub-accounts will remain available. If any relevant asset exceeds $1 and the deadline is missed, the entire account will be restricted during processing, and positions in the affected sub-accounts will be liquidated at the mark price at the time of processing with no fees. Arc mainnet launched on September 16, 2026, with institutional founding validators including BlackRock, DTCC, ICE, Visa, and Mastercard.
