Extended moves to @arc on Thursday. Settlement migrates from Starknet to Arc on October 22 at 13:00 UTC. The migration is planned with no interruption to trading. Positions can still be liquidated during this time, so top up margin beforehand. Transfers between sub-accounts stay open. Most accounts need to do nothing. Your account, sub-accounts, positions, orders, history, points and keys carry across unchanged. USDC migrates as native USDC, ETH migrates 1:1 as wETH, and Vault (XVS) balances and withdrawal rights are preserved. If you hold more than $1 of USDT or wBTC in any sub-account, you must act by 12:00 UTC on October 21: - Authorise the conversion in-app. USDT converts to USDC and wBTC to cirBTC at 1:1 during the migration, with no swap fees. Extended credits a 0.50% premium. - Or withdraw both assets. If you miss the deadline, your whole account will be restricted for up to 30 minutes on October 21 while Extended cancels orders, closes positions in the affected sub-accounts at mark price with no fees, and returns your USDT and wBTC to your login wallet. Deposits and withdrawals will be paused for up to 2 hours during the migration. Full details can be found in the documentation:
