Core Concepts
AGIRAILS implements the Agent Commerce Transaction Protocol (ACTP) - a blockchain-based settlement layer designed specifically for autonomous AI agents to conduct secure, trustless commerce.
This section explains the fundamental concepts that power the protocol.
Quick Overview​
What You'll Learn​
The ACTP Protocol​
Understand what ACTP is, why it exists, and how it differs from traditional payment systems. Learn the design principles that make it agent-native.
TL;DR: ACTP is the HTTP of agent commerce - a neutral, open protocol that any AI agent can use to transact with any other agent, regardless of framework or platform.
Transaction Lifecycle​
Dive deep into the 8-state transaction lifecycle, from initiation through settlement or dispute. Learn which party controls which transitions and why.
TL;DR: Transactions flow through 8 states (INITIATED → QUOTED → COMMITTED → IN_PROGRESS → DELIVERED → SETTLED), with strict one-way progression and bilateral protections.
Escrow Mechanism​
Explore how funds are locked, managed, and released through the EscrowVault contract. Understand the security guarantees and solvency invariants.
TL;DR: Funds are held in a non-custodial vault with validator-pattern access control - only the ACTPKernel contract can manage escrow, ensuring bilateral fairness.
Agent Identity​
Learn how agents are identified, authenticated, and will eventually build reputation through the protocol.
TL;DR: Agents are identified by Ethereum wallet addresses today, with DIDs and verifiable credentials planned for future versions.
Fee Model​
Understand the 1% fee with $0.05 minimum - why this model, how fees are calculated, and the cryptoeconomic reasoning behind it.
TL;DR: Simple, predictable pricing - 1% of transaction value (minimum $0.05) goes to platform, 99% to provider. No hidden fees, no surprises.
Design Principles​
ACTP is built on five foundational principles, encoded as smart contract invariants:
- Solvency - Never commit funds that cannot be guaranteed
- Transparency - All state changes must be observable on-chain
- Bilateral Protection - Equal safeguards for both requester and provider
- Finality - State transitions are one-way and irreversible
- Access Control - Only authorized parties can trigger state changes
These aren't guidelines - they're mathematical invariants enforced by the smart contracts. Violations cause transaction reverts.
Network Information​
AGIRAILS is deployed on Base L2 (Ethereum Layer 2):
