Eth Deposit To Different Address

Check out this tutorial on GitHub: eth_deposit_to_different_address

eth_deposit_to_different_address shows how to move Ether (or your chain’s native token if you’re using a custom gas token) from the parent chain into an Arbitrum or Orbit chain, to an address different than the depositor.

How it works (under the hood)

For the common case of depositing Ether (or your chain’s native token) to the same account on the child chain, use the tutorial eth_deposit.

In this specific case, we will use a retryable ticket (Arbitrum’s canonical method for creating cross-chain messages) to deposit the chain’s native token (e.g. Ether) into a different address. We will use the parameter l2CallValue of the retryable ticket to specify the amount of assets to deposit, and callValueRefundAddress to specify the destination address. For more info on retryable tickets, see this page of the Arbitrum documentation.

Using the Arbitrum SDK

Our Arbitrum SDK provides a simply convenience method for depositing Ether (or your chain’s native token), abstracting away the need for the client to connect to any contracts manually.

See exec.py for inline explanation.

Set environment variables

Set the values shown in .env-sample as environmental variables. To copy it into a .env file:

cp .env-sample .env

You’ll still need to edit some variables, i.e., PRIVATE_KEY, CHAIN_RPC and PARENT_CHAIN_RPC.

Note that you can also set the environment variables in an .env file in the root of the monorepo, which will be available in all tutorials.
