Pilot runbook → Your AI agent just placed an order, deleted a row, sent an email, merged a PR. Can you prove exactly what it did — to an auditor, a customer, or yourself after an incident? Signet is the independent verification layer for agent actions. Every tool call gets a signed receipt that anyone can verify offline, without trusting the platform that hosted the agent or the vendor that stored the logs. Your agents run on their infrastructure. The proof belongs to you. Why Not Just Logs? Traditional logs tell you what a platform says happened. They're mutable, provider-dependent, and unverifiable without trusting the party that wrote them. Signet receipts are different. Modify any field — tool name, parameters, timestamp, signer — and the Ed25519 signature breaks.
