Every Hive receipt is one ML-DSA-65 signature (NIST FIPS 204) over the exact state an agent saw before it acted. It takes about 7ms to produce and settles per receipt in USDC on Base. Choose a primitive below, run a real call against the live signer, and read the signed envelope back. No signup wall.
Keyless primitives sign for real in your browser. Tap a card to load it into the console below. AFiR-family primitives are live behind an API key. ARSC is the settlement layer those receipts ride on.
This posts the exact request shown to the live Hive signer and renders the signed envelope it returns. Fail-closed primitives reject inconsistent input with a 400. That is the point.
// Choose a primitive and press “Sign it live”.
Every primitive meters on the same ladder. A receipt is one signed envelope. Rates below are the default Standard signature. Stronger tiers (PQ, MAX) carry the same volume discount on a higher base. Usage is uncapped: no monthly minimum, no ceiling. You pay for exactly what you sign. See the full signature × volume matrix. Roll-ups are free.
Lowest-friction hook-in: start free with an instant key, run on the live endpoints above, and switch to paid metering over x402 / USDC on Base when you cross the Build tier. Same rail you just signed against. Sovereign and on-prem licensing is available for teams that need custom custody.
Grab a free key and keep signing on the same live endpoints, or talk to us about a license for high-volume and on-prem custody.
