If these faucets aren't working, you can opt to purchase Goerli with regular ETH (for instance, on the Arbitrum network). This is a beneficial option that can save you a ton of time and stress. Additionally, you'll need a modest amount of USDC on the Polygon network. You can either exchange MATIC within MetaMask, deposit from an exchange, or choose any other method that suits you.
Testing the bridge between Goerli and Caldera Rollup
- Launch the bridge and initiate a transfer from Goerli Ethereum to the Goerli Testnet Caldera Chain.
