Your AI agent acted, and you are liable for it. A log you wrote, control, and could edit is not evidence to a regulator, a merchant, or a counterparty. They have no reason to take your word, and you cannot reconstruct the proof after the action already happened.
Every agent action is tied to a cryptographic identity, a key only that agent holds, not a name in a log.
A signed verdict that the action was inside the owner mandate, issued at the moment it happened.
Any merchant, PSP, or auditor verifies the verdict against Fidacy public keys. No access to your systems, no trust in you required.
A tamper-evident, hash-chained record the other side will actually accept.
Your agent takes the action it was built to take.
Fidacy issues a signed verdict over the action, the mandate, and the agent identity, in milliseconds.
Any counterparty verifies the verdict against public keys, anywhere, with no account.
Send an agent action. Get back approve / review / deny and a cryptographically signed verdict you can check against our public JWKS. No trust in us required.
The market says this layer has to exist. It's running, self-serve: spin up your org, connect an agent in one MCP install, and verify the verdict yourself. No sales call.
