Developing with Testnet

Prepare Wallet

When using Carbonmark locally with Testnet, you will need to get the corresponding tokens which work with the carbonmark contract on Mumbai.

C3 tokens

• "0xa1c1cCD8C61FeC141AAed6B279Fa4400b68101d4" See on Mumbai
• "0xE5d7FEbFf7d73C5a5AfA97047C7863Cd1f6D0748" See on Mumbai
• => Ask a backend dev to get those tokens!

Matics

USDCs

Get the correct USDCs on Mumbai which work with Carbonmark Testnet:

• https://mumbai.polygonscan.com/address/0x284A5F4d90a49F7eb21C055eA3C824603314B1E7#writeContract
• connect your wallet
• Use the "mint" function

Prepare Localhost

✅ With your prepared tokens you can now run localhost with npm run dev-carbonmark and connect your wallet with Mumbai during development.

Change localhost to Mainnet:

In case you want to develop with Mainnet: In the file carbonmark/lib/constants.ts change the DEFAULT_NETWORK to "mainnet" => see the lines here
