<Warning>
  **Idempotency on errors:** On 4xx or 5xx, Privy caches the response and replays it for the same
  key. Generate a new key to retry after a server error. Policy violations are an exception and
  allow same-key retries.
</Warning>

<Warning>
  The wallet RPC endpoint is a synchronous endpoint, and a successful response indicates that the
  transaction has been broadcasted to the network. Transactions may get broadcasted but still fail
  to be confirmed by the network. The endpoint does not wait for confirmation or retry if the
  transaction fails to be confirmed. To handle these scenarios, see our guide on [speeding up
  transactions](/recipes/speeding-up-transactions).
