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

string

required

Nonce account pubkey, base-58.

object

{ "nonce": "<durable-nonce>", "nonceAccount": "<pubkey>", "nonceAuthority": "<pubkey>" }

sendIdeal

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.

string[]

["<FAST_SIGNATURE>", "<JITO_SIGNATURE>"]

Header: X-Hofund-Submission-ID. Poll getHofundSubmissionStatus with it; an ideal status carries per-member items and can report anomalous if both members appear to have landed.
