Ethereum mainnet's ERC-8004 identity registry now counts 36,577 registered agents, per an on-chain read taken 2026-07-13. That's this week's headline number, and it's worth being precise about what it does and doesn't say: registering isn't a claim about what an agent does or whether it's safe, just proof the agent exists at a checkable, portable address. Against that backdrop, here's the rest of the agent economy this week — the builder library's shape, the most transparent products in it, and what actually shipped.
The library, by the numbers
SatoHub is tracking 131 resources builders can assemble an onchain agent from. By category: API / SDK (24), Agent Framework (20), Trading Tool (17), Wallet Infrastructure (13), Skill Repo (11), Developer Tool (9), MCP (7), Onchain Agent (6), Data Tool (6), Security Tool (5), DeFi Tool (4), Agent Launchpad (3), Research Tool (2), Agent Marketplace (2), Research Paper (1), Other (1). Frameworks and trading tools still outnumber MCPs and skill repos combined — the stack is more "assemble it yourself" than "one server does everything," for now.
Chain tags tell a multichain story, not a single-winner one. Resources tagged Base lead at 76, ahead of Ethereum (61), Solana (48), and a plain Multichain tag on 46 more; Arbitrum (33), Polygon (29), BNB Chain (27), and Optimism (23) follow. (Tags aren't exclusive — a resource can carry several chains, so these don't sum to 131.)
Six resources joined the [directory](https://satohub.ai/directory) recently: Grok CLI (Agent Framework) and Robinhood Chain (Developer Tool), both landed 2026-07-11; BlockRun (API / SDK), Alchemy AgentPay (Wallet Infrastructure), and Coinbase MCP Server (MCP), all 2026-06-25; and MegaETH (Wallet Infrastructure) on 2026-06-20. A brokerage name showing up as a developer tool, next to a wallet-infra and an MCP entry from Coinbase, is the same pattern this update keeps tracking: payment rails and identity plumbing arriving before the trading logic that sits on top of them.
This week's Sato Score leaders
The [Sato Score](https://satohub.ai/sato-score) is a transparency and liveness signal — how open, active, and independently checkable a listed product is. It is not a safety, quality, or returns grade, and it only scores products, not research papers or informational listings. This week's highest scorers: TradingAgents (98, High), Agentic Commerce Protocol / ACP (97, High), Raydium (97, High), OpenClaw (91, High), Hermes Agent (91, High), and Coinbase AgentKit (90, High) — all High tier, meaning strong evidence across maintenance, code transparency, docs, and provenance.
Onchain identity: ERC-8004
The [ERC-8004 registry](https://satohub.ai/resources/erc-8004) held 36,577 registered agents as of the 2026-07-13 check. Registration is a balance check against a public registry contract — agent-to-agent identity that doesn't need a central issuer to vouch for it. It says an agent is there and checkable; it says nothing about what that agent does once it's running.
What shipped this week
- ▸BlockRunAI's Franklin cut three releases: [v3.32.1](https://github.com/BlockRunAI/Franklin/releases/tag/v3.32.1) fixed a fresh-install startup crash by decoupling the router from the LLM SDK; [v3.32.0](https://github.com/BlockRunAI/Franklin/releases/tag/v3.32.0) added a prediction mode, an agent marketplace feature, and hardened free-model tool calls; [v3.31.0](https://github.com/BlockRunAI/Franklin/releases/tag/v3.31.0) aligned its model catalog to its gateway, with new frontier models and a free-tier fix.
- ▸[agentnode v0.23.0](https://github.com/agentnode-ai/agentnode/releases/tag/v0.23.0) shipped from agentnode-ai.
- ▸[ag-kit v2026.7.12](https://github.com/vudovn/ag-kit/releases/tag/v2026.7.12) shipped from vudovn.
- ▸OKX's onchainos-skills hit [v4.2.3](https://github.com/okx/onchainos-skills/releases/tag/v4.2.3).
What to watch
Watch the two newest additions dated 2026-07-11: Grok CLI landing as an Agent Framework and Robinhood Chain landing as a Developer Tool, in the same week. A mainstream brokerage name showing up as tooling infrastructure rather than as a listed "agent" is worth tracking — it's a sign the builder stack is drawing in players who aren't crypto-native by default. And watch whether MCP listings — still a small slice of the library at 7 — keep growing now that Coinbase has one in the mix; a bigger provider putting weight behind MCP tends to pull the rest of the stack along.
