PRODUCT

You're the one in charge of your AI agent. But it doesn't know your limits.

Give agents narrow, signed authority for consequential work. Fidacy assesses the agent and action against that mandate, issues a verdict anyone can verify, and keeps the evidence. When money moves, the same decision becomes a binding firewall.

// HOW IT WORKS

Mandate → Assess → Verdict → Verify → Evidence

01

Mandate

Create, delegate or revoke a durable authority document for a named agent and a bounded action. The policy is signed, versioned and never left to a prompt.

02

Assess and decide

Fidacy checks the exact action, its agent identity and the active mandate, then returns allow, review or deny with the signed verdict and its reasons.

03

Verify

A customer, counterparty, rail or regulator verifies the decision against Fidacy's public key. No one has to trust the party that took the action.

for payments, the decision also becomes an enforceable one-time grant
04

Enforce

When it is money, the verdict is binding. The agent calls request_payment; an approve mints a short-lived Ed25519 grant the executor verifies before money moves. A deny mints nothing. A duplicate invoice or a redirected wire (BEC) is stopped at the gate by Fidacy, not the payment rail.

05

Evidence

Every decision lands in a hash-chained, append-only record whose head is committed to Bitcoin through public checkpoints. Prove later exactly what was decided, and verify it offline. Not even Fidacy can rewrite it.

Try it live: the demo runs a signed decision in your browser. The proof sandbox then runs a payment through the firewall and lets you test the evidence trail yourself.

// CAPABILITIES

Led by the decision, not the fraud.

// YOU NEVER HAVE TO TAKE OUR WORD

The padlock, not the promise.

SSL did not ask you to trust a company. It made every connection verifiable. Fidacy does the same for agents: you do not trust the issuer, you check the signature. A signed verdict from Fidacy is a padlock, recognizable and verifiable by anyone, on any rail and in any jurisdiction. Never having to trust us is the point.

// VISION · ROADMAP

Governed by the jurisdiction that runs it. Deterministic policy, verifiable audit, EU-aligned by design. Roadmap: in-jurisdiction / data-residency / self-host deployment for sovereign and regulated buyers, built against signed pilots.

Don't trust us, verify it. Then create an organization, issue a mandate and connect an agent. One install ships the signed decision, local observer and payment firewall.
