Native browser v0.2.0 verified build

Browser actions.
Receipts you can verify.

MnemoPay is the control and evidence layer for agents that handle money or take consequential web actions. Governed sessions enforce authority before an action. Signed bundles and an external notary make the result independently checkable afterward.

One product, two controlled surfaces

Use the mode that matches the action.

Agent runtime

Governed interaction

@mnemopay/browser wraps controlled Playwright, Browserbase, and Stagehand sessions. Navigation, clicks, form fills, submits, screenshots, budget checks, and policy decisions are recorded through the session boundary.

Use this for agent-run interactive work. It mediates supported session actions; it does not claim visibility into unrelated browsing performed outside that session.

Operator desktop

Verified inspection

MnemoPay Native Browser v0.2.0 pins approved public fetches, protects its signing identity with the operating-system vault, and exports DID-signed evidence bundles that can receive an external notary receipt.

Use this for human review and evidence export. Freeform WebView browsing is explicitly outside complete mediation coverage.

Case study - native browser v0.2.0

A closed evidence loop.

Built and verified on May 25, 2026. This is the first browser release in which exported inspection evidence can be signed locally, received by an external service, signed again under a separate DID, and checked by the desktop before it reports remote anchoring.

Identity

Ed25519 signing key stored in the platform credential vault, with legacy key migration on first secure launch.

Network boundary

Verified inspection pins approved DNS resolutions through fetch and rejects private or local targets.

Independent anchor

Gateway notary verifies the browser signature, stores the statement, and signs a receipt under its own public DID.

Verification

Frontend build, Rust checks, linting, and packaged Windows installers completed; receipt protocol has automated gateway tests.

Operating proof

1. Inspect the notary

The gateway publishes the public DID used to verify external receipt signatures.

Authority before action. Evidence after it.

That is the MnemoPay product: policy-controlled agents, payment and browser action surfaces, and proof a buyer can independently inspect.
