Main contracts are written in
- ./contracts/TokenBsc.sol
- ./contracts/TokenEth.sol
- ./contracts/BridgeBsc.sol
- ./contracts/BridgeEth.sol
Each deployment environment has a different set of mandatory environment variables. Add the secrets required for the deployment environment to .env
Make sure to provide the 64 character long hexa-decimal PRIVATE_KEY. The associated address will inherit the tokens created by the contract deployment.
Deploy the smart contract to the desired environment with the provided commands. The address of the deployed contract will be printed to the console output:
