Most “failed to fetch” errors are simply a result of an overloaded public access point. Transaction finality is never guaranteed until the block is confirmed by multiple peers. Check the contract’s event logs to see if a specific flag was raised during execution. Facing a contracts timeout usually indicates a problem with the chosen RPC node.
The protocol might require an extra signature step when dealing with hardware wallets. The speed of innovation in crypto means that errors are a sign of active growth. The documentation for this specific module usually includes a section on error handling. Verify that the token decimals are handled correctly in your transaction input.
Make sure your contracts integration uses the latest stable version of the SDK. The experience gained from troubleshooting will serve you well in the future.
