Sequesign binds the mandate to the evidence. Every recorded action is hash‑chained, witness‑signed, and sealed with the mandate into a tamper‑evident receipt that anyone can verify offline.
Six stages, one chain of custody. The delegation terms go in before the work starts; the evidence comes out signed by every party that touched it.
Pick or write a work template: scope, policy, expected actions, required attesters.
Open a session bound to the mandate. The agent's identity and authority are fixed at the start.
Each action you record is hash‑chained in sequence with its evidence. Nothing can be reordered or removed.
The receipt is finalized and witness‑signed. From here, any change is detectable.
Approvers and counterparties countersign the sealed record by hash. Same facts, every signature.
Anyone checks the package offline, or against a published trust anchor. No account. No vendor.
The receipt format and verifier are open: that's how the receipt becomes common ground. Identity, anchoring, and multi‑party workflows are the managed layers, and that's where the assurance climbs.
Tamper‑evident receipts for delegated agent work: recorded actions hash‑chained, witness‑signed, sealed against a pre‑bound mandate. Agent claims become proof.
Independent verification from the package alone: integrity and mandate conformance checked offline, with zero trust in us required.
Enrolled agent and author identity. A receipt proves not just what happened, but which registered agent acted, and on whose authority.
Managed storage, published trust anchors, and permanent citable receipt URLs. The self‑anchored receipt becomes the authoritative record.
Approvals and counterparty countersignatures bound to the sealed receipt by hash. Every party attests to the same immutable facts.
A log tells you what an agent did. A Sequesign receipt proves what it was authorized to do, and that the two match. Templates capture the delegation terms up front: spending limits, allowed actions, required evidence, who must countersign. The receipt is evaluated against the mandate at seal time, not reconstructed in a dispute.
Browse the template library →Logs are editable, deletable, and hosted by the party with the most to gain from changing them. Sequesign chains every action to the one before it and has an independent witness sign the seal. Alter one byte after the fact and verification fails, loudly, for everyone.
Read the architecture →Disputes over delegated work usually mean two parties, two records, and no shared ground truth. Sequesign approvals and countersignatures bind to the sealed receipt by hash: the delegator, the reviewer, and the counterparty each attest to one immutable record. When everyone signed the same receipt, there is nothing left to argue about.
See the countersign flow →A trust product you have to trust is a contradiction. Any Sequesign package verifies offline from the files alone: hash integrity, sequence, witness signature, and conformance to the embedded mandate. Those are the legs that make a receipt evidence, and they never require asking us. Authorship assurance is the graded leg: anchor a registered author key when the stakes call for it.
Run the verifier →Delegation terms, agent identity, and policy context are fixed into the session before the first action is taken. Authority is declared, not inferred later.
Actions chain to each other, a witness signs the seal, attesters countersign by hash, and any verifier on earth can check the result without us.
Wherever an agent's action would matter in an audit, a dispute, or a regulator's file, the receipt belongs next to the work.
Agents are calling payers and submitting authorizations today. When CMS or a health system asks what was submitted and under whose authority, a sealed receipt answers in seconds.
Approvals, reconciliations, and vendor spend executed by agents inherit the same audit obligations as the humans they replaced. Receipts make the SOX conversation short.
Authorization protocols prove what an agent may spend. Sequesign proves what it actually did with that authority, closing the loop between intent and settlement.
When agents draft, file, and docket, privilege and malpractice exposure follow. A receipt is the difference between a billing narrative and admissible evidence of what was done.
When a machine acts in the physical world — inside authorized airspace, under a speed or altitude limit — "it says it stayed in bounds" isn't evidence. A sealed record of what it did, and where, is.
When an agent drafts and publishes, readers deserve to know what it was sourced from and whether a human signed off. A content credential turns the byline's claim into something anyone can verify.
The EU AI Act's Article 12 requires high‑risk AI systems to keep records that make their operation traceable. Financial regulators are converging on mandate‑based authorization and audit trails for agent‑initiated transactions. Sequesign is the evidence layer those obligations assume you already have.
