W3Ledger MCP Server
A self-verifying ledger for AI agents — every transaction is cryptographically signed and chain-linked.
W3Ledger (Rolledge) is an MCP (Model Context Protocol) server that gives AI agents the ability to check token balances, create and claim gift cards, create and claim sponsor cards, and process dual-signed purchases — all secured by cryptographic signatures.
Every write operation requires dual signatures (sender + receiver/distribution). The server-side Lambda functions verify all signatures and enforce chain continuity. The MCP server is a thin HTTP client — it cannot bypass security.
