# POST /broadcast_tx_async

`POST /broadcast_tx_async`

[Deprecated] Sends a transaction and immediately returns transaction hash. Consider using send_tx instead.

## Request body

- JsonRpcRequestForBroadcastTxAsync
  - `id` string — JSON-RPC request id. Auto-populated; can be any string.
  - `jsonrpc` '2.0' — JSON-RPC protocol version. Always `2.0`.
  - `method` 'broadcast_tx_async', required
  - `params` RpcSendTransactionRequest, required
    - `signed_tx_base64` string, byte, required
    - `wait_until` 'NONE' | 'INCLUDED' | 'EXECUTED_OPTIMISTIC' | 'INCLUDED_FINAL' | 'EXECUTED' | 'FINAL' — How long the RPC should wait before returning a transaction result. Each value waits for a stricter execution milestone than the previous one. Defaults to `EXECUTED_OPTIMISTIC`. - `NONE`: Transaction is waiting to be included into a block. - `INCLUDED`: Transaction is included in a block (block may not be finalized). - `EXECUTED_OPTIMISTIC` (default): Included + all non-refund receipts executed (blocks may not be finalized). - `INCLUDED_FINAL`: Transaction is included in a finalized block. - `EXECUTED`: Included in a finalized block + all non-refund receipts executed. - `FINAL`: Included in a finalized block + all receipts (including refunds) finalized.
