What's better than a testnet bridge? A second cheaper alternative. I'm excited to introduce Faucetful (live at https://faucetful.app) - a bridge from Arbitrum Mainnet to Ethereum Goerli built on top of Hyperlane's Permissionless Interoperability stack.
Now, you can get Goerli ETH for a fraction of the gas cost of LayerZero's Testnet Bridge. TLDR: you can swap native ETH on Arbitrum Mainnet into synthetic GoerliETH (GETH) which gets unwrapped by Faucetful into native ETH on Goerli.
