The process of migrating TRX tokens is described in the official documentation on GitHub:

1. Access Your Wallet: Check your TRX balance in the list of Ethereum tokens.

2. Send Tokens: Send your old ERC20 TRX tokens to migration smart contract.

3. Confirmation: After the transaction is confirmed and broadcasted to the blockchain, the migration process will start, and your wallet will be credited with new TRX tokens. Depending on network usage, it may take 5–30 minutes to process the migration.
