On February 21st, 2023, LayerZero launched a bridge between mainnet ETH and Goerli testnet ETH. This means that developers can now exchange ETH on the Goerli network for mainnet ETH, and vice versa.
Why is there a need for a bridge between mainnet ETH and Goerli ETH?
We know that anyone who has developed on Goerli has encountered the same problem: it's difficult to obtain a certain amount of Goerli-ETH.
The mainnet ETH and Goerli ETH bridge was developed by LayerZero, stemming from a large-scale test they conducted on the Goerli testnet.
At that time, LayerZero had been trying to claim enough ETH on the Goerli faucet for several days without success, and ultimately had to buy a sufficient amount of Goerli ETH through OTC on Twitter.
Therefore, LayerZero launched the mainnet ETH and Goerli ETH bridge, and created an open ETH/GOERLI-ETH real-time pricing market.
The initial price for Goerli-ETH was set at $0.10, with a seed in the pool of 12,500 Goerli-ETH. These pools are open and hosted on Uniswap on Ethereum and Goerli. The community is welcome to join as liquidity providers and actively trade to achieve true price discovery and balance. These two pools are listed as: Goerli:
· ETH/mETH ("Mainnet ETH")
· Ethereum: ETH/gETH ("Goerli ETH")
How to exchange from mainnet ETH to Goerli-ETH?
The ETH to Goerli-ETH bridge enables seamless asset transfer between the Ethereum mainnet and the GOERLI testnet. Users can easily exchange mainnet ETH for Goerli ETH and bridge them securely with LayerZero.
The execution steps are as follows:
1. Exchange ETH/gETH on mainnet Ethereum.
2. Bridge gETH from mainnet Ethereum to Goerli testnet.
3. Unpack gETH to ETH on Goerli testnet.
Similarly, users who have the demand can directly transfer mainnet ETH to Goerli mETH or transfer Goerli-ETH to mainnet gETH, and can directly provide liquidity and trade via Uniswap UI or through a merge method on https://testnetbridge.com.
