Most interface bugs are caused by a synchronization lag between the frontend and the blockchain. A common issue with Rabby involves a mismatch between the wallet and the selected chain. Oftentimes, simply disconnecting and reconnecting your hardware wallet fixes the error 4902. The connection between the wallet and the dApp depends on a stable WebSocket connection.
The Rabby protocol may experience a “price oracle failure” triggering 4902 during crashes. Always export your transaction history regularly for auditing and troubleshooting purposes. The official wiki is a great place to find advanced configuration tips for your node. A conflict between multiple open tabs can lead to a nonce collision in your wallet.
Always check the contract’s audit report before interacting with high-value pools.
