Rule. Every listing in ERC-8004: Trustless Agents’s own category (API / SDK) that carries a Sato Score, ordered by score tier, observed liveness, deploy-spec and reproduced-install evidence, and chain overlap with ERC-8004: Trustless Agents.
This page ranks peers on how open, active and verifiable each one is — the same evidence Sato Hub publishes everywhere else. It is not a quality, safety or performance ranking, it declares no winner, and it cannot tell you which of these fits your codebase. A Sato Score is not an audit: none of these has been security-reviewed by Sato Hub, and a listing with no earned verification is self-reported.
| # | Alternative | Sato Score | Liveness | Chains | Differs on |
|---|---|---|---|---|---|
| 1 | Enso✓ reproduced An intent-based onchain execution engine and API that lets developers and agents bundle multi-step DeFi actions into a single transaction. npm install @ensofinance/sdk install reproduced by Sato Hub | High | Active · 12d ago | Ethereum, Base, Arbitrum, Optimism, Polygon, Multichain | Also on Optimism, Polygon; partly open source; deploys as npm, API. |
| 2 | Hyperliquid Python SDK✓ reviewed The official open-source Python SDK for programmatic trading on the Hyperliquid perpetuals DEX. pip install hyperliquid-python-sdk install reproduced by Sato Hub | High | Quiet · 5mo ago | Arbitrum, Multichain, Hyperliquid | Also on Hyperliquid; does not list Ethereum, Base; deploys as Self-hosted, pip. |
| 3 | World AgentKit✓ reviewed SDK from World (Tools for Humanity) that lets AI agents present a zero-knowledge proof a verified human authorized them, combined with x402 payments. npm install @worldcoin/agentkit install reproduced by Sato Hub | High | Active · 8d ago | Base | Does not list Ethereum, Multichain, Arbitrum; partly open source; deploys as npm. |
| 4 | PMXT✓ reproduced Open-source unified prediction-market API with a hosted MCP: market search, events, order books, and prices across venues. npx -y @pmxt/mcp install reproduced by Sato Hub | High | Active · 28d ago | Multichain | Does not list Ethereum, Base, Arbitrum; deploys as Hosted, Self-hosted. |
| 5 | Flaunch✓ reproduced Uniswap-V4-based token launch protocol on Base with a TypeScript SDK and its own MCP server. npm install @flaunch/sdk install reproduced by Sato Hub | High | Active · 7d ago | Base | Typed as venue rather than tool/service; does not list Ethereum, Multichain, Arbitrum. |
| 6 | OpenSea Agent Skill✓ reviewed Official OpenSea agent skill and MCP server letting AI agents query NFT/token data and execute marketplace operations such as listing, offers, and token swaps. npx skills add ProjectOpenSea/opensea-skill install as documented by the project — not reproduced | High | Active · 23d ago | Ethereum, Base, Solana, Polygon, Arbitrum, Optimism | Also on Solana, Polygon, Optimism; does not list Multichain; deploys as MCP server, API, Self-hosted. |
| 7 | Cross-chain swap/settlement API solved by the NEAR Intents solver network; also an MPP payment method so agents pay 402s from any chain. no deploy spec on record | High | Active · 6d ago | Near, Ethereum, Bitcoin, Solana, Base, Arbitrum, TON, Multichain | Also on Near, Bitcoin, Solana, TON; partly open source. |
| 8 | x402 OpenAI (Python)✓ reproduced Drop-in OpenAI Python client with transparent x402 micropayment support. pip install x402-openai[evm] install reproduced by Sato Hub | High | Active · 2d ago | Ethereum, Base, Solana | Also on Solana; does not list Multichain, Arbitrum; deploys as pip. |
| 9 | Exa✓ probed Web search and content-retrieval API built for AI; /search and /contents can be paid per request over x402. no deploy spec on record | High | Active · today | Base, Solana | Also on Solana; does not list Ethereum, Multichain, Arbitrum; partly open source; deploys as Hosted/Remote. |
| 10 | Decentralized AI inference network with an OpenAI-compatible Inference API and open-source consumer and provider node software. no deploy spec on record | High | Active · 1d ago | Base | Typed as infrastructure rather than tool/service; does not list Ethereum, Multichain, Arbitrum; deploys as Hosted API, Desktop app, CLI. |
“Differs on” is derived from the records — type, chains, openness and deployment — and states a difference, never a preference. ✓ marks an earned state named as what was checked; none of them is a safety claim.

Questions about alternatives to ERC-8004: Trustless Agents
- What are the alternatives to ERC-8004: Trustless Agents?
- Enso, Hyperliquid Python SDK, World AgentKit, PMXT, Flaunch, OpenSea Agent Skill, NEAR Intents 1Click API (+ MPP payment method), x402 OpenAI (Python), Exa, MorpheusAI are listed in the same category as ERC-8004: Trustless Agents (API / SDK), as of 2026-10-28. The order is Sato Score and observed evidence, not a quality judgment.
- Which alternatives to ERC-8004: Trustless Agents are open source?
- 6 of 10: Hyperliquid Python SDK, PMXT, Flaunch, OpenSea Agent Skill, x402 OpenAI (Python), MorpheusAI. Openness is read from each project's own published license or repository.
- Which alternatives run on the same chains as ERC-8004: Trustless Agents?
- 10: Enso, Hyperliquid Python SDK, World AgentKit, PMXT, Flaunch, OpenSea Agent Skill, NEAR Intents 1Click API (+ MPP payment method), x402 OpenAI (Python), Exa, MorpheusAI. Chain support is self-declared by each project unless a named check says otherwise on its listing.
- Has Sato Hub verified any of these?
- Sato Hub reproduced the documented install for 6 of them: Enso, Hyperliquid Python SDK, World AgentKit, PMXT, Flaunch, x402 OpenAI (Python). Reproducing an install means the documented setup was actually run — it is not a security review, and Sato Hub holds no security assessment of any of these.
- How is this list of alternatives built?
- It is a rule over live records, not a hand-written list: every listing in ERC-8004: Trustless Agents's own category that carries a Sato Score, ordered by the same evidence the rest of the site ranks on — Sato Score tier, whether an endpoint answered our probe, whether a deploy spec exists and was reproduced, a sustained observed record, and chain overlap with ERC-8004: Trustless Agents. It is rebuilt from the records, so it changes when they do.
