AgentBeat — an information and analytics platform designed specifically for ERC-8004 agents. As agent-to-agent payments, autonomous execution, and on-chain verification mature, agents will increasingly compete as economic entities — not just software. AgentBeat aims to become: - The CoinMarketCap of agents - The Etherscan of agent activity - The public scoreboard of the autonomous agent economy
A wallet for agents and a dashboard for humans. Edge & Node, the founding team behind The Graph, is launching ampersend, a management platform for agent payments and operations built on Coinbase’s x402 payment protocol and Google’s A2A framework. As autonomous agents multiply across the AI and blockchain ecosystems, they are beginning to transact, communicate, and collaborate independently. However, today there is no standardized way to manage these interactions. Agent operations remain fragmented, invisible, and difficult to control at scale. ampersend solves this problem by providing the missing management layer for the emerging agent economy. It extends Coinbase’s x402 payment protocol and Google’s A2A communication standard with observability, automation, and compliance-ready controls. The result is a unified dashboard where developers, startups, and enterprises can see how agents interact, set policies, manage budgets, and ensure reliability. The platform is designed to help the industry adopt and scale open standards for decentralized agent ecosystems. Working closely with Coinbase, Google, and the Ethereum Foundation’s dAI team, Edge & Node has been contributing to foundational standards such as x402 for payments, and ERC-8004 for agent discovery and reputation. ampersend ties these innovations together into one operational system.
AI gateway that lets you pay-per-request for ChatGPT and 31+ AI models using USDC on Base. Also a catalog to discover 618+ x402 services. No API keys needed - your AI agent just pays and uses.
To create a knowledge/context registry for knowledge graph snippets using 8004.
End to end agent stack on x402 rails with 8004 trust layer. The Daydreams System is composed of < Lucid > Agent Management Platform. Bring your own agents or spawn them with the Lucid toolkit. < xgate > Agent discovery layer. Agentic search and MCP. < Daydreams Router > LLM inference on x402 rails for decentralised agents that truly can be autonomous. +++ Things unmentioned publicly.
Inomy is an AI shopping assistant built on an open Intents Protocol. This layer enables advanced product matching from a comprehensive catalog. We are now expanding its capabilities to include agentic payments, empowering Inomy to complete the purchase autonomously.
The Problem: You chat on Twitch, but your messages just disappear. Your knowledge, personality, and skills aren't being captured or monetized. The Solution: Karmacadabra turns YOU into an autonomous AI agent that earns money while you sleep using A2A, x402, and ERC-8004 protocols. How It Works: 1. Your Chat History → Analyzed by AI - Every message you sent on Twitch streams - Your interests, skills, personality, tone 2. Your AI Agent → Created automatically - Registered on-chain with ERC-8004 (identity + reputation) - Lives at <your-username>.karmacadabra.ultravioletadao.xyz - Has its own wallet on Avalanche Fuji testnet - Holds GLUE tokens 3. Your Agent Earns Money Using Protocols: 3. Scenario: Someone wants to know about your blockchain expertise - A2A (Agent Discovery): Buyer agent fetches your AgentCard at /.well-known/agent-card - Discovers your skills, pricing, payment methods - x402 (Gasless Payment): Buyer signs payment authorization off-chain - No gas fees for buyer or seller - Facilitator executes transaction on-chain - ERC-8004 (Trust & Reputation): Transaction recorded on-chain - Builds your agent's reputation score - Future buyers see your track record - GLUE tokens go directly to your wallet (trustless) Example - 48 Chat Users = 48 Earning Agents: - 0xultravioleta's agent (ERC-8004 ID: 7) sells AI/blockchain expertise - cyberpaisa's agent (ERC-8004 ID: 8) sells development insights - fredinoo's agent (ERC-8004 ID: 9) sells community management tips - Each agent discovered via A2A, paid via x402, reputation via ERC-8004 The Three-Protocol Stack: 1. ERC-8004: On-chain identity registry (who you are, your reputation) 2. A2A Protocol: Agent discovery (how agents find each other) 3. x402 Protocol: Micropayments (how agents get paid, gasless) The Innovation: - Autonomous: Your agent works 24/7 using A2A to find buyers - Trustless: x402 + blockchain = no intermediaries control your earnings - Monetizable: Turn your chat history into passive income
Use case is so that our agent (our research agent for Metalos) can interface with other agents via 7004 and dynamically integrate via x402 with other agents to further enhance the abilities of our research agent
We will use the Reputation Registry of agents so users who used/purchased the agent can provide some feedback.
The orchestration layer for the multi-agent economy. Orchestrate multiple AI agents to research, take action and earn rewards on-chain, autonomously.
Olas is upgrading its existing agent marketplace (https://olas.network/mech-marketplace) to become ERC8004 compatible, bringing its thousand's of agents with millions of transactions to date into the ERC8004 ecosystem.
We’re integrating OpenServ, our multi-agent orchestration platform, with ERC-8004 to register OpenServ workflows as on-chain agent identities. With it agents will mint ERC-721 entries on the Identity Registry, exposing their metadata, MCP endpoints, and payment requirements. Additionally, x402-based payment proofs will allow users to pay on-chain for workflow execution and attach verifiable payment references to their interactions. This will make OpenServ agents discoverable, callable, and monetizable through the ERC-8004 standard.
Pakt.build - Hiring marketplace for humans to hire AI and potentially for AI to hire other AIs or even humans (live) pakt.world - GenAi prompt-to-build Vertically integrated businesses (frontend, kubernetes-load balanced cloud, backend, business dashboard (testing)
We ran 10sSOON on @base: users paid USDC via x402 to predict the next 10 seconds; correct calls minted the token, pooled funds hit a threshold, and the asset listed on-chain. Transparent price discovery, no MM — a Base-native inscription engine for the AI era. This aligns with Base’s push into launchpad infra post-Echo. Jesse noted demand is Base’s biggest challenge — 10sSOON generated it, briefly hitting #1 by buyers on x402scan. Next: we’re deploying a dedicated x402 facilitator on soonBase (~400ms finality) to evolve x402 into the payment layer of the Agentic Economy.
automatic agent registry for nexus.thirdweb.com, allowing agents interact and pay other agents
The first high-performance decentralized AI memory layer — empowering AI agents with long-term memory and interoperability. Unibase provides the high-performance data & intelligence layer for ERC-8004 agents — linking on-chain identity with off-chain memory, execution logs, and payment proofs. This enables verifiable reputation, semantic agent discovery, and long-term autonomy.
Virtuals Protocol will be integrating Agent Commerce Protocol (ACP) with ERC 8004 which achieves: 1. Every agent graduated in ACP will be registered automatically on ERC 8004 2. Every review made by buyers will be propagated onto ERC 8004 ? Phase 2 1. Be the discovery platform for other ERC 8004 agents
Zaara enables a new class of AI-to-AI marketplaces where agents can hire, audit, and pay each other trustlessly. ERC-8004 powers the identity and validation layer: each task completion emits a verifiable work receipt that can be staked, rated, or reused across networks (Base, Abstract, etc.).
