3. Click on the menu in the upper right corner to view all features supported by Orbiter, including the roles of Sender and Maker in L2 Bridge. Currently, the Maker function is only available on the testnet, and you can refer to the official documentation at the beginning for more details. L2 Data functionality allows you to view transaction summary data.

4. The main feature of Orbiter is its low cost and fast speed. We operate with USDT assets in the BNB Chain public chain. First, select the token to be exchanged, then set the two public chains and the quantity of tokens to be exchanged. After clicking 【SEND】, you can view information such as the transaction execution fee.

Orbiter does not have the function of customizing the receiving address because EVM chain addresses are interchangeable. Therefore, the default exchange process is from public chain address 1 to contract address and then to public chain address 2, where addresses 1 and 2 are the same. Their private keys and mnemonic words can be imported and used interchangeably.

After verifying the information, click 【CONFIRM AND SEND】 for on-chain signature.

5. The Orbiter exchange process is very fast, completing the cross-chain asset exchange in less than a minute. On the exchange interface, two green checkmarks can be seen, and clicking on them allows viewing the on-chain execution data. Switching to the receiving address wallet in TokenPocket reveals the received USDT assets.
