# sendIdeal and getNonce

> Submit a fast/Jito pair that shares a durable nonce so only one can land, and fetch the nonce it needs.

An ideal pair is two versions of the same intent: one tuned for the fast rails (priority fee), one for Jito (tip). Both use the same durable nonce, so whichever lands first cancels the other. Both methods live on `/hofund`.

## getNonce

<ParamField body="params[0]" type="string" required>
  Nonce account pubkey, base-58.
</ParamField>

<ResponseField name="result" type="object">
  `{ "nonce": "<durable-nonce>", "nonceAccount": "<pubkey>", "nonceAuthority": "<pubkey>" }`
</ResponseField>

## sendIdeal

<ParamField body="params[0]" type="string[]" required>
  Exactly two fully signed transactions built on the same durable nonce: the fast-rail transaction first, the Jito transaction second. Canonical padded base64, at most 1232 bytes each. No options object.
</ParamField>

<ResponseField name="result" type="string[]">
  `["<FAST_SIGNATURE>", "<JITO_SIGNATURE>"]`
</ResponseField>

Header: `X-Hofund-Submission-ID`. Poll [`getHofundSubmissionStatus`](/api-reference/hofund/status-and-tips) with it; an ideal status carries per-member `items` and can report `anomalous` if both members appear to have landed.
