An Intensive CoLearning program for AI agent developers to explore the core tech stack behind Decentralized and Trustless Agents — including ERC-8004, A2A, AP2, and x402. Through self check-ins, workshops, and example projects, participants will master the framework for next-generation agent collaboration and value exchange.
Phase 1 of “Let’s Build Trustless Agents”, co-hosted by LXDAO and ETHPanda, with special support from the EF dAI team. Community -> https://t.me/ERC8004

- In-depth analysis of the ERC-8004 standard: Identity Registry, Reputation Registry, and Verification Registry.
- Hands-on: Create an on-chain identity for your agent and implement a simple off-chain reputation feedback mechanism.

- Master how agents autonomously discover and communicate via the Agent-to-Agent (A2A) architecture.
- Decode the AP2 protocol: Understand agent descriptor files, capability declarations, and interaction flows.
- Hands-on: Enable your agent to discover other agents and initiate collaboration requests.

- Dissect how the x402 protocol utilizes the HTTP 402 status code to enable "gasless" micro-payments.
- Integrate EIP-3009 to achieve automated settlement for agent services and resource access control.
- Hands-on: Integrate x402 payment functionality into your agent service, enabling "pay-per-call".

- Integrate knowledge from the first three modules to build a full-lifecycle Trustless Agent.
- Implement the full automated workflow: from identity registration and reputation accumulation to autonomous collaboration and service settlement.
- Project Demo & Code Review: share your project with the community and get feedback.
Some Project Examples:
ERC-8004 Trustless Agents Example https://github.com/vistara-apps/erc-8004-example.
Arena SDK with 8004 identities + A2A + ChaosChain integration for receipt logged on-chain and payment released on verification. https://github.com/vistara-apps/agent-arena-v1
Welcome to propose more ideas and examples!
Challenge 1: On-Chain vs Off-Chain Data
Question: The community debates how much data to put on-chain. If you had to choose between "events only" vs "minimal view functions" vs "full on-chain indexing," which would you pick and why?
Challenge 2: Agent Identity System
Question: Should ERC-8004 use domains, URLs, ENS, or DIDs for agent identity? What are the trade-offs of each approach?
Challenge 3: Reputation Design
Question: How would you design a reputation system that avoids a single score but still provides useful information for users?
Challenge 4: Verification Methods
Question: Which verification approach would you trust more: TEE proofs, ZK proofs, or sampling/reexecution? Why?
Challenge 5: Economic Incentives
Question: Should ERC-8004 include payment mechanisms in the core standard, or keep them as external extensions?

- The greatest reward is the knowledge you gain — and the chance to meet like-minded builders through their shared notes.
- Outstanding builders may be invited to demo on stage at Devconnect Trustless Agent Day on Nov 21.
- More benefits will be announced with partners — stay active and complete your daily check-ins!
- The entire learning process is mainly self-directed, based on the provided materials, with discussions in the community and participation in community calls.
- You’ll need to check in daily by posting learning notes to show your progress. All check-ins will be recorded on GitHub as open-source learning notes.
