Deploy ERC20 Token Remote

Deploy ERC20TokenRemote on C-Chain

Using the forge create command, we will deploy the ERC20TokenRemote.sol contract, passing in the following constructor arguments:

• Interchain Messaging Registry Address (for C-Chain)
• Interchain Messaging Manager (our funded address)
• Source Blockchain ID (hexidecimal representation of our Avalanche L1's Blockchain ID myblockchain)
• Token Home Address (address of NativeTokenHome.sol deployed on our Avalanche L1 myblockchain in the last step)
• Token Name (input in the constructor of the wrapped token contract)
• Token Symbol (input in the constructor of the wrapped token contract)
• Token Decimals (uint8 integer representing number of decimal places for the ERC20 token being created; typically 18 decimals)

Register ERC20TokenRemote on C-Chain with NativeTokenHome on myblockchain

After deploying the bridge contracts, you'll need to register the remote bridge by sending a dummy message using the registerWithHome method. This message includes details which inform the home bridge about your destination blockchain and bridge settings, eg. initialReserveImbalance.

cast send --rpc-url local-c --private-key $PK $ERC20_TOKEN_REMOTE_C_CHAIN "registerWithHome((address, uint256))" "(0x0000000000000000000000000000000000000000, 0)"
