Bridging ERC20 Tokens from L2 to L1

Go to the Withdraw tab of the rollup bridge at https://bridge.ata.network. In the token selector, choose the MTK test token and input the amount of tokens you wish to withdraw from Automata Testnet.

After you click on "Withdraw" and confirm the transaction in your wallet, the withdrawal process will start: the verifier will post the transaction commitment on Ethereum Sepolia, and a challenge period will follow. During the challenge period, any verifier can challenge the transaction if it is fraudulent.

After the challenge period is over, you can withdraw your MTK tokens on Ethereum Sepolia. In order to do that, you will first have to switch back to Ethereum Sepolia.

After you switch the network, click on "Finalize Withdrawal", confirm the transaction with your wallet, and wait for your tokens to arrive on Ethereum Sepolia.
