Deploy the bridge

This section outlines the process of deploying the Chromia and EVM components of a token bridge, using BSC testnet as an example.

These steps can also be adapted for Ethereum mainnet, BSC mainnet, or Ethereum Sepolia by adjusting network configurations.

Deploy an ERC20 token

Deploy an ERC20 token on an EVM chain (this guide uses BSC testnet with the Test ALICE token).

Deploy the token bridge contract

Deploy the token bridge contract on an EVM chain to enable cross-chain transfers.

Deploy Chromia bridge chains

Set up the Event Receiver Chain and deploy the Bridge Chain on Chromia to handle cross-chain transactions.

Register the Chromia bridge component on EVM

Connect the deployed bridges by setting the bridge_demo_brid in the EVM bridge contract.

Test your bridge using the frontend

Use the frontend to verify your deployment, approve token transfers, and bridge tokens.
