Delegare (Latin for “to delegate”) is a trustless payment authorization layer that allows human users to grant spending power to AI agents without handing over credit card numbers or private keys.

​
The Problem

AI agents today are limited by their inability to perform economic actions. Existing solutions require either:
  1. Full Custody: Giving an agent your credit card or wallet seed phrase (massive security risk).
  2. Pre-funding: Locking capital into a per-agent wallet (capital inefficient).

​
The Delegare Solution

Delegare introduces Spending Delegates — cryptographically signed tokens that enforce strict spending limits, merchant allowlists, and time-based expirations.

Human-in-the-loop Setup

Users authorize a delegate once via a secure UI.

Agent-Led Execution

Agents use the delegateToken to authorize payments autonomously.

Dual-Rail Settlement

Settle via Stripe (Fiat) or Base L2 (Crypto) with automatic fallback.

Atomic Limits

DynamoDB-backed atomic counters prevent overspending and race conditions.

​
How it works

  1. Merchant requests a setup session.
  2. User authorizes limits (e.g., “50/mototal,max50/mo total, max 10 per tx”).
  3. Agent receives a delegateToken.
  4. Agent calls /charge with the token whenever it needs to buy something.
  5. Vault validates limits atomically and executes the payment on the best available rail.
