Binance announced it will support a USDT contract swap on Optimism Network, with the change taking effect on September 17, 2026. The exchange will suspend deposits and withdrawals for USDT on Optimism at 02:00 UTC on that date to facilitate the migration.

Contract swaps occur when a blockchain project migrates its token to a new smart contract, typically to implement upgrades or address technical needs. Users holding USDT on Optimism will need to complete the swap through Binance during the maintenance window to ensure their funds reflect the updated contract.

The specific mechanics of the swap process and whether Binance will automate the conversion for users or require manual action have not been detailed in available announcements.
