# sendTransaction

> Submits a signed transaction to the cluster for processing.

Submits a signed transaction to the cluster for processing.

## On ThorNode

Forwarded once to the transaction gateway with an **8 s** timeout and never resubmitted by ThorEdge; on a `502` you decide whether to rebuild and resend. Counts against the TPS cap as well as the RPS cap. Parameters are forwarded unchanged. The result is the transaction signature; a result of `"OK"` means the gateway accepted the request but no upstream returned a signature. Treat `"OK"` as not confirmed: check `getSignatureStatuses` with the signature you computed locally and resend if it does not appear.

## Parameters

<ParamField body="transaction" type="string" required>
  The fully-signed Solana transaction encoded as a base-58 string for blockchain submission.
</ParamField>

<ParamField body="encoding" type="string">
  Data encoding format used for the Solana transaction payload.

  * `base58`
  * `base64`
</ParamField>

<ParamField body="skipPreflight" type="boolean">
  When true, bypasses Solana's preflight transaction validation for faster submission.
</ParamField>

<ParamField body="preflightCommitment" type="string">
  Network commitment level for transaction validation checks.

  * `confirmed`
  * `finalized`
  * `processed`
</ParamField>

<ParamField body="maxRetries" type="number">
  Maximum number of automatic retry attempts for failed Solana transaction submissions.
</ParamField>

<ParamField body="minContextSlot" type="number">
  Minimum slot required for transaction processing.
</ParamField>

## Response

<ResponseField name="result" type="string">
  The unique Solana transaction signature for tracking confirmation status and transaction history.
</ResponseField>
