According to CoinMeta, the decentralized perpetual contract trading platform Extended, created by the former Revolut team, announced that it will migrate its settlement network from Starknet to the Layer blockchain under Circle during the week of October 19th. Trading will continue during the migration period, but deposits and withdrawals may be suspended for about 2 hours. After the migration, the platform will use USDC to charge gas fees, and plans to expand the range of perpetual contracts for stocks, commodities, and crypto assets. Since Arc does not support USDT and WBTC, users holding related assets worth more than 1 dollar must complete exchanges or withdrawals by 12:00 UTC on October 21st; otherwise, their accounts may be restricted, and related positions may be forcibly liquidated.
