Core Concepts

Agent identity, machine-scale payments, compliance primitives, and custody patterns.

Topic 3
Core Concepts

Catena Labs is built on a few core ideas that make safe agent commerce possible.

These concepts work together to let AI agents use money without losing control, safety, or trust.

1. Agent Identity

What this means

Agent identity means every AI agent has a clear, unique identity in the financial system.

  • Not anonymous
  • Not shared
  • Not vague

Why this matters

Without identity:

  • You don’t know which agent acted
  • You don’t know who is responsible
  • You can’t track behavior or mistakes

That makes trust impossible.

How Catena handles it

With Catena:

  • Every agent is registered as a distinct entity
  • Each agent is linked to a human or organization
  • Every action is traceable to that agent

So when an agent spends money, you always know:

  • Which agent acted
  • Who owns it
  • Under what rules
2. Machine Scale Payments

What this means

Machine scale payments are payments made at the speed machines work.

That means:

  • Instant
  • Always on
  • No waiting for office hours
  • No manual approvals every time

Why this matters

AI agents:

  • Operate 24/7
  • Make decisions in seconds
  • Work across countries

Traditional finance is too slow for this.

How Catena handles it

Catena allows agents to:

  • Send and receive money instantly
  • Pay other agents or services automatically
  • Operate globally without delays

All payments still follow rules set by humans.

3. Compliance Primitives

What this means

Compliance primitives are basic building blocks that enforce rules automatically.

Instead of checking rules later, the system prevents bad actions from happening.

Why this matters

Rules like:

  • Spending limits
  • Approved recipients
  • Time restrictions
  • Usage conditions

Are often enforced manually today or ignored. That creates risk.

How Catena handles it

Catena builds rules directly into how money moves:

  • An agent cannot break spending limits
  • An agent cannot pay unapproved targets
  • An agent cannot act outside allowed times

Rules are not optional they are enforced by default.

4. Custody Patterns

What this means

Custody is about who holds the money and who controls it. This is critical for safety.

Why this matters

AI agents should:

  • Use money
  • But not own money
  • And not have unlimited access

Without proper custody, mistakes become disasters.

How Catena handles it

With Catena:

  • Money is held securely under human or organizational ownership
  • Agents are granted limited, rule based access
  • Access can be changed, paused, or removed at any time

So: humans own the funds and agents operate within strict boundaries.

How these concepts work together

When combined:

  • Agent identity provides clarity
  • Machine scale payments provide speed
  • Compliance primitives provide safety
  • Custody patterns provide control

Together, they create trustworthy agent commerce.
