SDK methods

Learn more about sending transactions using our SDKs here.

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.

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.

Headers

string

required

ID of your Privy app.

string

Request authorization signature. If multiple signatures are required, they should be comma separated.

string

Request expiry. Value is a Unix timestamp in milliseconds representing the deadline by which the request must be processed.

Path Parameters

string

required

ID of the wallet to get.

Body

object

string

Base64 encoded serialized transaction to sign.

string

Available options: base64

Optional parameter to enable gas sponsorship for this transaction. Learn more.

string

Optional developer-provided reference ID for transaction reconciliation. Must be unique per transaction and up to 64 characters. Use this to correlate transactions with your own internal records. The reference_id is included in transaction webhook payloads and can be used to look up transactions.

boolean

Optional. If set to true, the signed transaction will be immediately returned after the enclave signs, and submission to the network will happen asynchronously. Useful if you want to minimize E2E latency, or if you want to submit to multiple endpoints to get the best transaction landing time possible. Note that enabling this option also disables network preflight checks to minimize latency, which means an invalid transaction will not return an error in the API response and will not fire webhooks. You are responsible for rebroadcasting and validating the transaction, which can be done against a Solana RPC endpoint using the signed_transaction from the response.

Lowest latency configuration: For minimum E2E latency, combine optimistic_broadcast with the x-privy-skip-simulation: true request header. This skips both simulation and broadcast confirmation, returning the signed transaction as fast as possible. Your application is then responsible for simulating (if desired) and broadcasting the transaction independently.
