The problem
Agents already act for people. They book, buy, reorder and reply. The service on the other side sees a request from software and has two questions it cannot answer:- Who is this agent acting for? A real person, or no one at all.
- Within what limits? What the person allowed, how much, and until when.
What Sumvin adds
Three things, each built on the one before.A Sigil
Your proof of personhood: a verified identity for you and your agents. You confirm your phone and your ID once. From then on, your agent carries proof that a real, verified person stands behind it. About Sigils
A Stamped Mandate
An authorisation you sign. It says what one agent may do — share data, prove who it acts for, or spend — and the limits it must keep to. Your agent can ask for one. Only you can approve it, with your passkey, in your own browser. About Stamped Mandates
An Errand
A standing purchase, run within a Stamped Mandate. Your agent creates the errand; Envoy, Sumvin’s money agent, runs it. Sumvin is a Visa Intelligent Commerce Launch Partner, and errands are built on Visa Intelligent Commerce. Payments are coming soon, in a fast-follow release. About errands
Why it matters to you
- You set the limits. Your agent never decides what it is allowed to do.
- You see every agent. Each agent you connect has its own identity under your Sigil, and you can revoke any one of them.
- You can stop it. Revoke a Stamped Mandate and the agent loses that permission.
Why it matters to whoever your agent deals with
A merchant or service receiving a request from your agent can check two facts before acting: a verified person stands behind this agent, and this request falls inside the limits that person signed. They do not need to trust the agent. They check the mandate. Check a mandateWhere to go next
