Errors

Errors from the Provider expose code, message, retryable, and optional retryAfter in seconds. Check code rather than relying on instanceof across scripts. Local utilities and cancellation may throw ordinary errors.

Code	Handling
USER_REJECTED	Preserve input and wait for another user action
UNAUTHORIZED	Request the required connection permissions
WALLET_LOCKED	Ask the user to unlock
CONTEXT_CHANGED	Discard the old session and reload
UNSUPPORTED_METHOD	Check capabilities
INVALID_PARAMS	Correct inputs
INSUFFICIENT_FUNDS	Check available BTC and tokens
QUOTE_EXPIRED	Refresh the quote
RATE_LIMITED	Wait according to retryAfter and reduce concurrency
TIMEOUT	Check transaction state before retrying
NETWORK_ERROR	Show the error and allow reads to refresh
EXTENSION_DISCONNECTED	Check the extension and reconnect
INTERNAL_ERROR	Report non-sensitive diagnostics

export function walletErrorMessage(error: unknown): string {
  if (typeof error === 'object' && error !== null && 'code' in error) {
    if (error.code === 'USER_REJECTED') return 'Request cancelled'
    if (error.code === 'CONTEXT_CHANGED') return 'Wallet changed. Reconnect.'
  }
  return error instanceof Error ? error.message : 'Wallet request failed'
}

Retry policy

Only retry reads explicitly marked retryable, using bounded backoff. The SDK does not remove upstream HTTP 429 limits. Do not automatically retry payments, asset mutations, or signatures. A timeout may occur after submission.
