Blockchain ecosystems continue to witness notable developments. Accordingly, the Ethereum Layer-2 network Optimism has successfully completed its transition from the OP Goerli testnet to the OP Sepolia testnet. The Goerli test network has been phased out by the Ethereum community since January 2023 and its use was only continued until the end of 2023.
Optimism Team Takes Noteworthy Step
OP Sepolia is showing progress towards a sustainable future, and the Optimism team is encouraging all applications and developers to move to OP Sepolia for all testing and development needs. Ethereum Goerli and its counterpart OP Goerli will be completely phased out by January 2024. When a testnet is phased out (as was the case with past Ropsten, Rinkeby, and Kovan testnets), it loses parity with the Ethereum Virtual Machine (EVM), making it unsafe and ineffective for testing applications and other Web3 projects.
To ensure your testnet application works as intended on the OP Sepolia testnet, all developers and end-users are encouraged by the team to make the transition before January 2024. Following this process, end-users wanting to trial in a testnet environment will begin to do so on the OP Sepolia testnet instead of OP Goerli. Testnet funds can be requested up to 1 test ETH per day through the Superchain faucet, which also supports Sepolia testnets.
The Web3 wallet Metamask already supports the OP Sepolia testnet network, so users can find network information through Metamask.
Blockchain Space and Testnet Processes
Blockchain developments, while exciting for users, can lead to significant losses due to issues in applications, particularly those in Layer-2 network projects. Therefore, testing an application on testnet networks before its market release is of great importance in the Web3 ecosystem.
During this process, application teams can address their own developments or involve users in the testing process through airdrop events. In the Ethereum ecosystem, this environment can be addressed through testnet ecosystems like Goerli or Sepolia.
