Cedulon Treats Missing Payment Receipts as Evidence

cedulon.com Observed source
Editorial interest 84/100 Selection signal · not a rating of the site

An open audit layer for agent-to-agent payments that links signed spend receipts to checkpointed chains and payment-rail extracts.

Landing page captured for the 2026-08-26 issue.

Field notes

Cedulon combines signed receipts, epoch checkpoints, and reconciliation against a payment rail’s extract, making the absence of a receipt an auditable discrepancy rather than an invisible gap. The displayed repository example applies limits of 10 USD per payment, 30 USD cumulatively, and three payments per hour. Its five MCP tools can be launched through npx using @cedulon/mcp-server, according to the homepage.
