# Onchain Agents — the scored, daily-updated index of the crypto agent stack

> 486 listings of what onchain AI agents are built from: agent frameworks,
> onchain action kits, MCP servers, wallets and key management, data and RPC,
> x402 payment rails, identity standards (ERC-8004, A2A), security tooling and
> trading venues. Rendered daily from satohub.ai. Last render: 2026-10-20.
> Every product listing carries a Sato Score: 0-100, measuring how OPEN, ACTIVE
> and VERIFIABLE a project is. It is NOT a safety, quality, security or returns
> grade, and nothing here is financial advice. Self-reported is not verified.
> Catalog data CC-BY-4.0, attribution: data by satohub.ai.

## Start here

- [The stack, layer by layer](https://raw.githubusercontent.com/satohubai/onchain-agents/main/README.md): the answer to "what do I build an onchain agent with" — nine layers, each a table of the highest-scored listings with chains, score, last activity and what we checked. It is the first section of the README.
- [Pages site](https://satohubai.github.io/onchain-agents/): the same, one page per layer
- Starting stacks: five example layer combinations built only from listings in this index — examples, not endorsements (README, after the stack section)

## Layers (one page each)

- [Agent runtimes & frameworks](https://raw.githubusercontent.com/satohubai/onchain-agents/main/docs/categories/agent-frameworks.md): The loop that runs the agent: prompting, memory, tool calls, scheduling. Pick this first — it decides what everything else plugs into.
- [Onchain action kits & SDKs](https://raw.githubusercontent.com/satohubai/onchain-agents/main/docs/categories/action-kits.md): Libraries that turn an agent's decision into a signed transaction — swap, transfer, mint, stake — without writing the chain plumbing yourself.
- [MCP servers](https://raw.githubusercontent.com/satohubai/onchain-agents/main/docs/categories/mcp-servers.md): Tool servers your agent calls over the Model Context Protocol. This is the largest layer in the index and the fastest-moving.
- [Wallets, keys & permissions](https://raw.githubusercontent.com/satohubai/onchain-agents/main/docs/categories/wallets-keys.md): Where the agent's key lives and what it is allowed to do: embedded wallets, MPC, smart accounts, session keys and spend permissions.
- [Data, RPC & indexing](https://raw.githubusercontent.com/satohubai/onchain-agents/main/docs/categories/data-rpc.md): What the agent knows before it acts: RPC access, market data, chain indexing, wallet and token analytics.
- [Payments & agent commerce](https://raw.githubusercontent.com/satohubai/onchain-agents/main/docs/categories/payments.md): How agents pay and get paid: x402 (HTTP 402 plus stablecoin), agent commerce protocols, and the stablecoin rails underneath.
- [Identity, discovery & standards](https://raw.githubusercontent.com/satohubai/onchain-agents/main/docs/categories/identity-discovery.md): How an agent is identified and found by other agents: ERC-8004 registration, MCP discovery, A2A agent cards.
- [Security & preflight](https://raw.githubusercontent.com/satohubai/onchain-agents/main/docs/categories/security.md): Checks you run before an agent installs, connects, signs or trades: contract and token screening, endpoint checks, monitoring.
- [Trading & DeFi venues](https://raw.githubusercontent.com/satohubai/onchain-agents/main/docs/categories/trading-venues.md): Where the agent actually trades: DEXs, aggregators, perps, lending and yield venues with programmatic access.

## Per-listing pages

- Every listing has a page at https://raw.githubusercontent.com/satohubai/onchain-agents/main/docs/listings/<slug>.md — facts, deploy spec, what we checked, links, citation
- Slugs are the `slug` field in data/index.json

## Data (stable, versioned)

- [index.json](https://raw.githubusercontent.com/satohubai/onchain-agents/main/data/index.json): full index, schema_version field, one object per resource
- [index.csv](https://raw.githubusercontent.com/satohubai/onchain-agents/main/data/index.csv): flat CSV of the same
- [Live export feed](https://satohub.ai/api/export/index.json): the upstream source; also .csv and .ndjson, with ?category= ?chain= ?standard= ?use_case= slices
- [All datasets](https://satohub.ai/datasets): every published dataset and its license
- On Hugging Face: [Onchain Agent Builder Bench](https://huggingface.co/datasets/SatoHub/onchain-agent-builder-bench) (eval) · [Sato MCP Tool-Calling](https://huggingface.co/datasets/SatoHub/sato-mcp-tool-calling) (training data)
- [Schemas](https://satohub.ai/schemas): versioned JSON Schemas for these formats
- [OpenAPI](https://satohub.ai/api/openapi.json): every public operation

## Query it live over MCP

- [Swap through a gate](https://raw.githubusercontent.com/satohubai/onchain-agents/main/docs/swap.md): how an agent gets a swap it is allowed to make — four dated verdicts, the owner's policy, a simulation, an unsigned transaction
- [Neutrality](https://raw.githubusercontent.com/satohubai/onchain-agents/main/NEUTRALITY.md): no project can pay to be listed, ranked or scored
