Extended is moving settlement from Starknet to Arc. The migration is scheduled to begin on 22 October 2026 at 13:00 UTC. Trading is expected to continue while deposits and withdrawals may be paused for a limited transition window.
What Users Need to Know
Most accounts are designed to migrate automatically, including account and sub-account structure, positions, orders, trading history and points. Users holding material USDT or wBTC balances were given separate conversion or withdrawal steps because those assets are not carried to Arc in the same form.
USDC, ETH and XVS
USDC is intended to move to native USDC on Arc through Circle’s cross-chain infrastructure. ETH is represented on Arc as wrapped ETH, while XVS and the associated Vault rights are intended to be preserved through the migration.
Before You Trade
Review the latest migration notices, collateral requirements and any asset-specific actions before the transition. Trading and network changes can create operational risk, so users should keep sufficient margin available around the migration window.
