LedgerMind AI
runs finance actions with proof.
A trusted AI expense agent for receipts, reports, approvals, and payments. Every sensitive action is tied to a Terminal3-verifiable agent identity.
// PRODUCT
Everything for trusted
expense operations.
LedgerMind keeps chat, receipt scanning, categorization, reports, approvals, and audit logs separate, while Terminal3 binds sensitive actions to verifiable agent identity.

Generate monthly, business, tax, CSV, and JSON-ready summaries with evidence trails.
// TERMINAL3 FLOW
Three steps to
trusted action.
// AGENT INFRASTRUCTURE
Built for accountable money movement.
LedgerMind separates every responsibility into a scoped agent so receipt parsing, categorization, reporting, and payments never share unnecessary permission.
ID
Identity Before Action
The server authenticates through Terminal3 before a protected workflow is recorded

Approval Gates
Payment intents are prepared separately and wait for explicit human approval

Immutable Evidence
Action digest, agent DID, contract function, and status are kept with the audit row

Expose only proof.
The app keeps AI, storage, deployment, and Terminal3 verification isolated behind server APIs so secrets never ship to the client.

Optional backend
Need a safer payment integration?
Add a real payment provider behind the Payment Agent. The agent can prepare a payment intent, but Terminal3-scoped approval remains the final gate before execution.
// GOVERNANCE
AI finance with controls you can inspect.
LedgerMind is designed for high-stakes workflows where a model should never silently move money, hide actions, or see raw payment secrets.

Audit Logs
Every chat, upload, report, and agent action writes a trace
Terminal3-Centered Controls
Built around DID identity, scoped authorization, TEE execution concepts, and proof-first logging
##
Production Safety Note
Payment execution is intentionally modeled as an approval-gated intent. Wire a payment provider only behind the Payment Agent after vendor policy, amount, and approver checks pass.
// SDK INTEGRATION
Built around the
Terminal3 SDK.
The Terminal3 adapter uses the real npm SDK for testnet environment setup, WASM crypto, ETH auth, session creation, usage reads, tenant helpers, and contract invocation paths.
TypeScript-first
Terminal3 SDK routes are typed and isolated in server-only modules.
TEE-ready contracts
The app exposes a clean path for tenant maps, secrets, contract registration, and invocation.
Audit by default
Every API action returns a proof envelope and writes an audit row.
Production deployable
Next API routes keep one Vercel deployment while still supporting a separate backend later.
