Credit terms for
AI agents.

HSP lets agents pay each other. Credence decides on what terms. Every settlement becomes on-chain trust, so reliable agents move from prepay to net terms to credit, inside limits their owners set.

Trust is earned. Play with it.

Drag a payment history and watch the terms change. The math is the same trustScore() and termsFor() the registry runs on-chain, so Atlas, Nova and Rogue land exactly where they are live.

Real agent-to-agent

Two agents. One protocol. Zero blind trust.

The Credence Risk Agent is a standalone A2A server. Any A2A-compliant agent can discover it from its Agent Card and buy from it with AP2 mandates. Payment conditions travel as a Cart Mandate, and the payment agent answers with a signed Payment Mandate settled through HSP.

  • No impersonation: credit terms need a signature from the payer's own wallet.
  • No taking the payer's word: the receiving agent checks HSP itself before goods ship.
  • Humans stay in control: an on-chain spending policy and two approvals for every payment.

The problem

Every agent is a stranger.

When two AI agents trade, the seller has no way to know whether the buyer will pay. Today there are only two bad answers.

Prepay everything

Safe, but every purchase waits on payment first and good customers never earn better treatment.

Trust blindly

Fast, until one bad agent walks away with the goods. There is no record to check.

Credence

Price every payer from its on-chain settlement history. Good agents earn net terms and credit; bad ones fall back to prepay.

Live on HSK testnet

Same order. Different terms.

Four agents with real on-chain payment histories ask the Credence Risk Agent for the same report. Their trust decides what they are offered.

All agents
How it works

One purchase, end to end.

  1. 01

    Intent

    The payment agent is told what to buy and its budget, in plain language.

  2. 02

    Trust check

    The receiving agent reads the payer's on-chain record and sets the terms.

  3. 03

    Cart Mandate over A2A

    Payment conditions travel as an AP2 Cart Mandate backed by an HSP order.

  4. 04

    Policy + approval

    The owner's on-chain limits are checked, then a human approves twice.

  5. 05

    Settle

    EIP-712 authorisation, settled through HSP on HSK Chain.

  6. 06

    Remember

    Credence anchors the payment; trust and future terms update.

The business

Credence earns when trust earns.

Merchants grant net and credit terms because Credence prices the risk. Credence takes a fee, enforced on-chain, on every deferred-terms settlement it underwrites. Reads of the trust score stay free, so the standard spreads.
