During the month, work centered on enhancing the stability of Ethereum RPC interactions within the mezo-org/mezod repository. The developer introduced a rate limiting feature to the Ethereum sidecar, implemented in Go, which allows users to configure the maximum number of RPC requests per minute. This backend development effort addressed the risk of provider throttling by capping requests, thereby improving reliability for automated workflows that depend on diverse Ethereum RPC services. By adding a new flag to control request rates, the solution leveraged skills in backend systems and RPC protocols to reduce provider quota errors and ensure more consistent service availability.
