Sato Hub: Onchain Agents

Build any crypto agent: Sato Hub maps the onchain tooling it needs (agent frameworks, crypto MCP servers, wallets and key management, x402 payments, DeFi and trading venues, onchain data) across Base, Solana, Ethereum and more, and turns your goal into a stack with install steps. Describe what the agent should do ("a trading agent on Base that pays for data with x402") and get picks from a daily-rebuilt index, each with its install steps, marked where Sato Hub has run them itself. x402: check an x402 endpoint before your agent pays it. One unpaid request reads its 402 payment terms (network, asset, amount, payTo), and the payee address can be checked before funds move. Pick an x402 endpoint for a task on observed readings. Sato Hub never sends or signs the payment. Two Sato Hub datasets are sold over x402 in USDC on Base. DeFi: quote a swap across the DEX aggregators on a chain, with the venue chosen on liveness, verification and price, and its fee disclosed. Read observed Uniswap v3 pool liquidity and volume by fee tier, and compare token launch venues. Transactions come back unsigned. Preflight before you install, connect or pay: give it a GitHub repo, npm package, MCP endpoint, agent or token address and get what is on record about it, when each fact was checked, and what is unknown. Give it an install command or MCP config and see whether it takes your wallet key, whether the key leaves, and whether it can move funds on its own. Also: search by chain or standard (x402, ERC-8004, MCP, A2A), compare two projects, follow releases and news, and read Agent Passports for registered agents. Sato Score measures openness, activity and verifiability — not a safety, profitability or endorsement rating. Every record links to a citable page. Public, no API key. Most tools only read. Four change state: submit a project, register an agent, watch a target for changes, and build an unsigned swap transaction. Sato Hub never holds keys, signs or broadcasts.
