Hyperliquid
Submit a signed Hyperliquid withdrawal (step 2 of 2)
Forwards your main wallet’s signed withdraw3 action to Hyperliquid. Kairos verifies the signature parses and then passes it through; the venue re-verifies it covers destination, amount and time, so a field altered after signing is rejected upstream.
Irreversible. A withdrawal that Hyperliquid accepts cannot be recalled. Kairos does not validate the destination address.
No Kairos-side idempotency. There is no in-flight tracking and no dedupe: calling this twice with the same time sends the same signed action twice, and the ONLY protection against a double withdrawal is Hyperliquid rejecting the replayed nonce. Do not build a blind retry loop on this endpoint.
A 400 conflates two very different outcomes. Hyperliquid rejected withdrawal: … is returned both for a genuine venue rejection AND for an HTTP/network failure reaching the venue — the underlying error type collapses them. On that error you cannot tell whether the withdrawal landed; query Hyperliquid directly before retrying.
Hyperliquid’s own withdrawal minimum and flat fee are enforced venue-side and surface through that same 400.
Auth & scope. Requires trade:execute for hyperliquid, wallet ownership, and the mutation gate. Not rate limited.

}Authorizations
Credential client id (kairos_ck_...). Must be sent together with X-Api-Key and X-Api-Secret.
64-char hex API key.
64-char hex API secret.
Body
application/json
The time from prepare. Doubles as the nonce — Hyperliquid's replay protection is the only thing preventing a duplicate withdrawal.
0x-prefixed 65-byte signature over the prepared typed data, produced by the main wallet. Kairos never signs a withdrawal.
Defaults to wallet_address. Must match what you signed, or Hyperliquid rejects it.
Response
The withdrawal was submitted to Hyperliquid. Submission only — not a settlement confirmation.
