According to Foresight News, OP Labs announced that the beta feature for custom gas tokens in the OP Stack has been discontinued. This feature allowed developers to access early versions of advanced functionalities, enabling teams to validate demand through data and user feedback. However, since May 2024, the usage of the custom gas token beta feature has steadily declined due to the development of ERC-4337 and Paymaster Services. OP Labs now recommends that all new chains launch with the standard ETH gas token configuration and utilize account abstraction tools, which allow users to pay gas fees with alternative tokens instead of relying on custom gas tokens.
