Questions people ask about data agents on Ethereum
- How many data tools support Ethereum?
- 34 as of 2026-10-15, matched by the same rule the Data page uses and then filtered to listings declaring Ethereum. data tool 16, api / sdk 7, mcp 7, security tool 2 — and the page exists only because the intersection clears a listing threshold.
- Why does this page exist rather than a filter?
- Because a filter is not citable. The intersection is computed from live records and a page is published only when it holds enough of them; the set grows as the index does and is never hand-written per keyword.
- Which of these are open and installable?
- 15 are open source and 21 publish a sato.deploy manifest with runtime, install and entry. 34 carry a Sato Score, a reading of how open, active and verifiable a project is — never a safety or returns grade.
- Which of these are open source?
- 15 of 34: Fetch.ai uAgents, DefiLlama, OpenSea Agent Skill, Philidor MCP, Bankless Onchain MCP, OKX OnchainOS Skills, CabalSpy Wallet Tracker, Celo MCP, graph-aave-mcp, ERC-8126: AI Agent Verification, DeFi Trading MCP, Cryo MCP Server and others.
- Which are actively maintained?
- 7 had a commit or release in the last 30 days: Fetch.ai uAgents, Zerion, DefiLlama, OpenSea Agent Skill, Nansen, OKX OnchainOS Skills, CabalSpy Wallet Tracker. Posts on X do not count. Activity is a recency signal, not a quality judgment.
- Which have an earned verification on Sato Hub?
- 12: Fetch.ai uAgents, Zerion, DefiLlama, OpenSea Agent Skill, Philidor MCP, Bankless Onchain MCP, Neynar, Orderly Network, Alchemy, graph-aave-mcp, ERC-8126: AI Agent Verification, DeFi Trading MCP. An earned check is named as what was checked (install reproduced, endpoint probed, on-chain identity read, reviewed against evidence); none is a safety claim.
- Which run as MCP servers?
- 13: Zerion, OpenSea Agent Skill, Philidor MCP, Bankless Onchain MCP, Orderly Network, ChainAware, Celo MCP, DeFi Trading MCP, Erigon MCP, Chainbase, Aave MCP by Junct, OneSource and others.
- How is this list ranked?
- Data agents on Ethereum is derived from Sato Hub's live records by a stated rule and ordered by Sato Score, a 0–100 measure of how open, active and verifiable each project is. It is not a quality ranking and declares no winner.
