Depositing funds with StarkGate

Using StarkGate to deposit L1 funds into the L2 Starknet requires StarkGate’s deposit function. The deposit function does the following:

  1. Transfers the funds from the user’s Ethereum account to the StarkGate L1 contract.

  2. Emits a Deposit event that includes the L1 and L2 addresses of the user, and the amount deposited.

  3. Sends a message to the corresponding L2 bridge with the amount deposited, and the recipient’s address.

Subsequently, the funds should be transferred to Starknet so that you can begin using them.

For more information on what happens during the transfer process, see L1→L2 transfer (deposit).

Prerequisites

  • An Ethereum block explorer, such as Etherscan.

  • Funds to transfer from L1 to L2, including enough to pay the fees required for the transfer.

  • The L1 address of the StarkGate bridge for the token you want to deposit. To view the token addresses for tokens on Mainnet or Sepolia testnet, see Bridged tokens and addresses.
