Before connecting, make sure you’ve installed the Metamask extension for Google Chrome and added three networks: Ethereum Goerli Network, zkSync Era Testnet Network, and Binance Smart Chain Testnet Network. If you’ve already completed this, please continue; otherwise, click here.

Open the Tusima zkBridge Testnet: https://bridgetest.tusima.network/. Click on the ‘Connect Wallet’ button in the top-right, then select ‘Metamask’ to connect your wallet and initiate a signature request. (Make sure your wallet has some Goerli ETH and zkSync ETH as gas tokens. If you don’t have any, Here are some websites where you can claim gas tokens. https://faucetlink.to/goerli )

Click the ‘Faucet’ button to claim test tokens for both the Goerli network and the zkSync Era Testnet network. After claiming, add the test tokens to Metamask. (Note: Claim Goerli tokens first, ‘Add’ to Metamask, then claim zkSync Testnet tokens and add them to Metamask; these are test tokens from two different chains.)

After claiming successfully, you can check in your wallet. You will have 1000 TSM, 1000 USDC, and 1000 USDT on both the Goerli network and zkSync Era Testnet network.

Click ‘Asset,’ choose ‘Transfer,’ select the desired chain and token, then enter the token amount.

The following demonstration is transferring TSM from the Goerli Network to the zkSync Era Testnet Network. Click ‘Approve’ to authorize the transaction.

Click the “Transfer” button and confirm the transaction in the Metamask.

Waiting for the asset cross-chain contract to complete zk circuit verification. The contract will verify the correct cross-chain information and execute the cross-chain operation. Once completed, the transaction’s execution hash will be displayed in the cross-chain progress. You can click on the hash to view the on-chain execution results.
