Extended to Migrate Settlement Network From Starknet to Arc
On-chain perpetual futures trading platform Extended is moving its settlement network from Starknet (STRK) to Arc. The transition is scheduled to take place during the week of October 19, 2026. While trading on the platform will remain active throughout the migration, users may experience a temporary pause in deposits and withdrawals lasting roughly two hours.
The shift introduces significant changes for asset holders because the Arc network does not support Tether (USDT) or Wrapped Bitcoin (wBTC). Users with balances of more than $1 in these specific tokens must convert or withdraw their holdings by October 21, 2026, at 8:00 PM. Failure to do so could result in restricted accounts and the forced liquidation of related positions. Following the migration, the trading platform will utilize USD Coin (USDC) to pay for network gas fees.
Looking forward, the platform intends to expand its perpetual contract trading offerings beyond digital assets to include stocks and commodities. Meanwhile, Starknet's native token (STRK) showed strong market activity, rising 32.09% to trade at 0.0734 USD on the day of the announcement.
