Register Remote with Home

Before you can bridge tokens, you need to register the ERC20TokenRemote with the NativeTokenHome. This establishes a secure connection between the contracts.

Why Registration?

Registration:

Creates a bidirectional link between home and remote contracts
Prevents unauthorized remote contracts from claiming tokens
Is a one-time setup per remote contract

Switch to C-Chain

Ensure your wallet is connected to Fuji C-Chain (where ERC20TokenRemote is deployed).

Register the Remote

Make sure you have:

Successfully deployed ERC20TokenRemote on C-Chain
Test AVAX for gas fees

Bridge State After Registration

After completing registration:

ERC20TokenRemote is registered with NativeTokenHome
Your L1's native token can now be bridged to C-Chain as ERC-20
ERC-20 tokens can be bridged back to your L1 as native tokens

Unlike native-token bridges (Chapters 1 and 3), this bridge does not require collateralization. The home contract simply locks tokens on one side and the remote mints on the other.

Next Steps

Your bridge is fully configured! Let's test it by bridging some tokens.
