Foresight News reported that OP Labs tweeted that the custom Gas token beta feature on OP Stack has been discontinued. The beta functionality allows developers to use early versions of higher demand features, enabling teams to validate requirements through the use of data and user feedback. But since May 2024, with the development of ERC-4337 and Paymaster Services, the usage of custom Gas token beta features has steadily declined. In addition, OP Labs recommends that all new chains be launched using standard ETH Gas token configurations and utilize account abstraction tools to allow users to pay Gas fees with other tokens instead of relying on custom Gas tokens.
