[Base Growth Lead: Builder codes allowing apps or protocols to self-label are now live on Base] Base Growth Lead Antonio García Martínez posted on the X platform that builder codes, which allow any app or protocol to self-label, are now live on Base. This feature will provide chain-level attribution support for all activities on the Base chain, enabling new business models at the application layer. Additionally, these codes will serve as a trust source for Base's future incentive programs. Developers can now register to obtain builder codes through the base.dev website.
