Limitations

When making requests to Solflare in Establishing a Connection, Sending a Transaction, or Signing a Message, Solflare may respond with an error.

Errors

The following is a list of all possible error codes and their meanings. These error messages are inspired by Ethereum's EIP-1474 and EIP-1193.

4100	Unauthorized	The requested method and/or account have not been authorized by the user.
4001	User Rejected Request	The user rejected the request through Solflare.
-32000	Invalid Input	Missing or invalid parameters.
-32002	Requested resource not available	This error occurs when an aapp attempts to submit a new transaction while Solflare's approval dialog is already open for a previous transaction. Only one approve window can be open at a time. Users should approve or reject their transactions before initiating a new transaction.
-32003	Transaction Rejected	Solflare does not recognize a valid transaction.
-32601	Method Not Found	Solflare does not recognize the method.

Typically, these errors will be easily parseable and have both a code and an explanation. For example:

try {
  await window.solana.signMessage();
} catch (err) {
  //  {code: 4100, message: 'The requested method and/or account has not been authorized by the user.'}
}
