Ending Support for Goerli Testnet on Ethereum, Arbitrum, and Optimism

Testnets are cost-effective environments for testing services before their deployment on the mainnet. However, as these testnets essentially function as networks, they can face congestion issues as their user base grows, leading to problems with faucets and node synchronization. To ensure optimal usability, Ethereum has been gradually phasing out its existing testnets while introducing new ones. Additionally, Arbitrum and Optimism are actively managing and updating testnets to offer developers an ideal environment for development and testing.

Consequently, a transition is underway from the previously widely used Goerli testnet to the newly launched Sepolia and Holesky testnets. These new testnets provide a more comfortable and efficient development environment. Arbitrum has announced its intention to cease Goerli support on November 17, 2023, while Optimism plans to discontinue Goerli support in the fourth quarter of 2023, with guidance provided for migrating to the Sepolia testnet.

With our upcoming update, Luniverse has made the decision to shift our support from Goerli to Sepolia on Arbitrum and Optimism. Furthermore, on the Ethereum network, we have introduced the Holesky testnet, which is the latest Ethereum testnet designed to offer developers an optimized environment for testing smart contracts, complete with an ample supply of testing ETH.
