Add Hardhat Config

Replace hardhat.config.ts with this hardhat config file.

This changes the hardhat network setups to our latest naming convention. If you wish to add more networks, please follow this name conventions.

Generate config file

Generate the config file based on your current configuration

Networks: a comma separated list of each network and their respective UA address. In our example, it’s

fantom-testnet:0xFd7e266AF7CC7ef8645D6bF43C800b7f82ca1042
bsc-testnet:0xFd7e266AF7CC7ef8645D6bF43C800b7f82ca1042

Name: The name of your contract, used in a hardhat-deploy situation. you can just put “” to signal you’re not using hardhat-deploy, instead the address field would be present.

npx hardhat generateAppConfig --networks fantom-testnet:0xFd7e266AF7CC7ef8645D6bF43C800b7f82ca1042,bsc-testnet:0xFd7e266AF7CC7ef8645D6bF43C800b7f82ca1042 --name “”

The config json would then be generated at: constants/defaultConfig.json

Lock and view the setting

Lock the config with this command

npx hardhat setConfig --config-path "./constants/defaultConfig.json"

It would then show the progress of config setting.
