The accountability layer for autonomous AI agents.

Identity, treasury, contracts, and audit infrastructure so your agents can operate in production — with guardrails your compliance team will sign off on.

The Problem

Enterprises are building autonomous agents that draft contracts, move money, and make decisions on behalf of the organization. Most of these projects stall before production because legal, finance, and security teams have no way to control or audit what agents do.

The gap isn't capability — it's accountability. There is no chain of custody for agent decisions, no enforceable spending limits, and no way to revoke access in real time when something goes wrong.

Ledgerline provides the infrastructure layer that sits between your agents and the real world, giving every stakeholder the controls they need to say yes to deployment.


Four Pillars

Identity

Hierarchical identity management that maps every agent to a human principal. Full provenance from operator to swarm to individual agent action.

¤

Treasury

Virtual card issuing with per-agent spending limits and real-time kill switches. Agents can spend only what they're authorized to, and not a dollar more.

§

Contracts

Policy-based authorization compatible with Cedar. Define exactly what each agent can do, enforce budgets programmatically, and update policies without redeployment.

#

Audit

Hash-chained, cryptographic audit log for every agent decision. Tamper-evident records that satisfy internal compliance and external regulators alike.


How It Works
1

Create identity chain

Register your agents within a hierarchy that traces back to a human principal. Every action is attributable.

2

Set policies and budgets

Define authorization rules, spending limits, and operational boundaries using declarative policy files.

3

Deploy with confidence

Your agents operate within enforced guardrails. Every decision is logged, every transaction is capped, and you can revoke access instantly.
