## sendTransaction

Submits a signed transaction to the cluster for processing.

This method does not alter the transaction in any way; it relays the
transaction created by clients to the node as-is.

If the node's rpc service receives the transaction, this method immediately
succeeds, without waiting for any confirmations. A successful response from
this method does not guarantee the transaction is processed or confirmed by the
cluster.

While the rpc service will reasonably retry to submit it, the transaction
could be rejected if transaction's `recent_blockhash` expires before it lands.

Use [`getSignatureStatuses`](#getsignaturestatuses) to ensure a transaction is processed and confirmed.

Before submitting, the following preflight checks are performed:

1. The transaction signatures are verified
2. The transaction is simulated against the bank slot specified by the preflight
   commitment. On failure an error will be returned. Preflight checks may be
   disabled if desired. It is recommended to specify the same commitment and
   preflight commitment to avoid confusing behavior.

The returned signature is the first signature in the transaction, which
is used to identify the transaction ([transaction id](../../terminology.md#transaction-id)).
This identifier can be easily extracted from the transaction data before
submission.

### Parameters:

<Parameter type={"string"} required={true}>
  Fully-signed Transaction, as encoded string.
</Parameter>

<Parameter type={"object"} optional={true}>

Configuration object containing the following optional fields:

<Field name="encoding" type="string" defaultValue="base58" href="/api/http#parsed-responses">

Encoding used for the transaction data.

Values: `base58` (_slow_, **DEPRECATED**), or `base64`.

</Field>

<Field name="skipPreflight" type="bool" defaultValue="false">
  if "true", skip the preflight transaction checks
</Field>

<Field
  name="preflightCommitment"
  type="string"
  href="/api/http#configuring-state-commitment"
  defaultValue="finalized"
>
  Commitment level to use for preflight.
</Field>

<Field name="maxRetries" type="usize">
  Maximum number of times for the RPC node to retry sending the transaction to
  the leader. If this parameter not provided, the RPC node will retry the
  transaction until it is finalized or until the blockhash expires.
</Field>

<Field name="minContextSlot" type="number">
  set the minimum slot at which to perform preflight transaction checks
</Field>

</Parameter>

### Result:

`<string>` - First Transaction Signature embedded in the transaction, as base-58 encoded string ([transaction id](../../terminology.md#transaction-id))
