Express Relay has been wound down
In July 2026, Pyth governance passed OP-PIP-124: Express Relay Wind-Down. Express Relay is no longer an actively supported Pyth product; the auction service, SDKs (@pythnetwork/express-relay-js, express_relay Python), and on-chain ExpressRelay contracts are being retired.
