How to bridge ERC20 tokens?

To bridge tokens via Arbitrum's standard ERC20 gateway, the first step involves creating a token and deploying it on the Layer 1 blockchain. This is crucial as it establishes the foundation for the bridging process.

Once the token is deployed, the next step is to identify the bridge contracts that need to be called. This involves understanding the various contracts involved in the bridging process, such as the router contract and the gateway contract. It is essential to have a clear understanding of these contracts to proceed further.

After identifying the necessary contracts, the third step is to approve the token allowance for the gateway contract. This allows the gateway contract to transfer the tokens from the user's wallet to the bridging contract.

The fourth step involves initiating the bridging process through the router contract. This contract facilitates the transfer of tokens from Layer 1 to Layer 2. By interacting with the router contract, users can start the bridging process and specify the destination address on Layer 1.
