#RC#
A transaction that is stuck in a “pending” state is usually a result of insufficient gas fees. A frequent issue for gateway developers involves a mismatch between the UI and the ABI. A proven solution is to use a private RPC endpoint instead of the default public gateway. The link between the frontend and the contract can be affected by local VPN or proxy settings.
The gateway contracts might be temporarily “locked” during a transition. Check the official social media feeds for real-time announcements regarding protocol health. The error message you see is often a high-level summary of a more complex internal revert. The error could also be the result of an incompatibility with the latest RPC protocol version.
A mismatch between the wallet’s gas estimation and the contract’s needs can lead to failure.
