Agent Economy on Ergo
The Base Layer for Autonomous Agent Payments
Core Idea
"Every AI system will need to pay and be paid. Ergo already has the primitives."
Autonomous AI agents are a fundamentally new kind of economic actor. They transact at machine speed, without persistent identity, at micropayment scale ($0.001 per API call), with conditional acceptance logic that no human-centric payment rail supports. Stripe requires KYC. Lightning requires persistent channels. Ethereum has non-deterministic gas and mandatory ETH pre-funding. Ergo is designed to satisfy the requirements agents have — at the protocol level, with no application-layer workarounds.
Why Ergo Is Different
Ergo's agent payment stack consists of four composable UTxO primitives: Reserve (collateral backing), Note (programmable bearer IOU), Tracker (anti-double-spend registry), and Acceptance Predicate (on-chain task completion condition). These aren't features bolted on for AI — they're protocol properties that emerge from eUTXO's deterministic execution, ErgoScript's expressive power, and Babel Fees' gas abstraction. ChainCash is an open-source prototype reference implementation of this stack — not audited and not production-ready.
Key Differentiators
Notes: programmable bearer IOUs transferable between agents without issuer round-trips
Acceptance Predicates: task completion logic enforced on-chain by miners, not your server
Babel Fees: agents pay fees in any token — zero ERG bootstrapping required
Deterministic eUTXO: agents know exact costs before submitting — no gas surprises
PoW: no validator multisig that can freeze agent infrastructure
