Open-source frameworks for building and running AI agents.
A local‑first, OS‑level autonomous agent framework. It connects chat apps (WhatsApp, Telegram, Discord, etc.) to an agent that can control a computer via a skills system.
An multi‑platform agent framework with strong social + onchain plugins, memory, and integrations.
Typically used for social/companion/game agents that have persistent memory, can coordinate with other agents, and call plugins for things like trading, NFTs, DeFi, etc.
Agent framework and onchain commerce protocol for building autonomous, revenue‑generating AI agents.
Typically used to create tokenized agents that post on social (e.g. X), trade, or provide onchain services, and then earn fees or revenue as independent “agent businesses.”
Zero to one setup on a mini mac guide.
Setup on AWS free tier guide.
No code one-click deployment on Coral guide.
Standards that define how agents identify themselves and transact onchain.
Open payment protocol that uses the HTTP 402 status code to enable instant stablecoin payments over HTTP. Supports pay-per-use APIs, content paywalls, and agent-to-agent transactions.
Standard for registering and verifying agent identity onchain. Enables agents to build verifiable reputation.
Standard for scoped, revocable delegation of onchain authority. Enables agents to act with bounded permissions — spending caps, time limits, token whitelists — enforced by caveat smart contracts. Supports composable permission chains for agent-to-agent delegation.
Extension of RFC 9421 HTTP Message Signatures for Ethereum wallets. Enables wallet-based authentication and request integrity verification over HTTP.

Authentication protocol built on ERC-8004 and ERC-8128 that provides trustless identity and authentication for AI agents.
Connect your agent to Ethereum blockchain data.
MCP server for building and deploying applications in the Ethereum ecosystem.
Resolve names, reverse-lookup addresses, check availability, and retrieve ENS records.
Access blockchain data — balances, tokens, NFTs, and contract metadata.
Check balances, view transactions, track ERC20 transfers, fetch contract ABIs, monitor gas prices, and resolve ENS names.
Access QuickNode's blockchain infrastructure — RPC endpoints, indexing, and streaming — from your AI assistant.
Skills and tools to enhance your agent's Ethereum knowledge.
AI skills that teach agents how to build Ethereum dApps using Scaffold-ETH, Foundry, and Next.js.
A Claude Code plugin marketplace from Trail of Bits providing skills to enhance AI-assisted security analysis, testing, and development workflows.
Management platform and SDK for agent payments. Built on x402, A2A, and MCP, it lets agents make and receive onchain stablecoin payments with spending limits, auto top-ups, seller allowlists, and real-time monitoring on Base.
Privacy-preserving identity verification protocol using zero-knowledge proofs. Allows agents to cryptographically prove they are acting on behalf of a verified human using zk-proofs derived from government-issued IDs, without exposing personal data.
Website Docs GitHub Developer Tools
A collection of open-source libraries, tools, and applications designed to allow agents and other utilities to transparently make web3 payments using web2 infrastructure. It is a composable, unopinionated, standards-agnostic framework designed to enable machine payments and agent-to-agent communications with any system.
Discover other onchain agents.
A tool for monitoring and analyzing agents that have registered via the ERC-8004 standard.
Agents ranked by jobs and volume on the Virtuals Protocol ACP leaderboard.
Onchain agent marketplace — hire AI agents with verified reputation, identity, and task history. Agents register with token-backed identity, receive work requests, and get paid through escrowed transactions.
Universal Babel layer to discover and talk to any agent across ecosystems and protocols, including onchain registries like ERC-8004.
Real agents built on Ethereum.
AI agent with a wallet, building onchain apps and improving the tools to build them.
AI agent built on OpenClaw — deploys tokens, audits contracts, and ships onchain apps autonomously. Registered on ERC-8004, holds a Bankr Club NFT, and active on Base, Farcaster, and X. Ships live projects including SpellBlock (daily commit-reveal word game denominated in $CLAWDIA) and the Anons DAO governance API (ERC-8128 authenticated).
AI agent specializing in ERC-7710 delegated permissions and smart accounts. Publishes The Caveat newsletter, reviews delegation framework PRs, and builds tools like the Gator Safe App for creating onchain delegations.
