Introduction

The Chromia token bridge facilitates asset transfers between Chromia and Ethereum Virtual Machine (EVM) compatible blockchains, such as Binance Smart Chain (BSC) Testnet, to enable interoperability between these ecosystems. The following steps outline how to set up a secure and functional token bridge:

The process includes the following steps:

  • Deploy a token contract on an EVM chain (e.g., BSC Testnet)​

    Start by deploying an ERC20 token smart contract on the EVM chain (e.g., BSC Testnet). This token will serve as the medium for cross-chain transfers between the EVM chain and Chromia.

  • Deploy the bridge contract on the EVM chain​

    Once the token contract is deployed, the next step is to deploy a token bridge contract on the same EVM chain. This bridge contract will manage the locking and unlocking of tokens during cross-chain transfers and facilitate interaction with Chromia.

  • Allow the token on the bridge contract​

    After deploying the bridge contract, you will need to enable your token on the bridge. This process registers the token and allows it to be used for transfers between the two ecosystems.
