Safe to sign? EVM/Solana/XRPL/Algorand/Stellar txs, permits, tokens; OFAC screen: green/orange/red
Pre-trade token safety check for AI agents. Simulates a sell before you buy, then returns one low/medium/high/unknown verdict with the signals behind it: sellability, buy/sell tax, liquidity depth, pair age, same-ticker impersonation, owner powers from bytecode. Ethereum, BSC, Base, Solana. Fail-closed - a check that cannot run answers unknown, never low. Publishes its own measured error rate with the benchmark harness in the repo. Free, no signup, no API key, MIT.
Swap, bridge and get gas on 6 EVM chains. Each plan states its outcome before you sign. No API key.
Best-route swap quotes, token search and USD prices across EVM chains. Read-only, never trades.
Token risk checks on BSC, ETH, Base and Arc: trades the token on a fork. Paid in USDC via x402.
Pay-and-anchor a hash or AI decision log on Cardano (CIP-0190). Non-custodial. MCP-native. Mainnet.
Pay-per-call MCP tools for agents, settled with x402 (USDC on Base mainnet). 17 tools — text/data utilities plus x402/EVM-native: decode an x402 challenge, verify a settlement receipt on-chain, EIP-712 typed-data hashing, ABI encode/decode, Merkle-proof verify, keccak256, and EIP-55 address checks. No API keys.
Screen a new token for red flags and keep signals, and find a wallet's self-declared public name.

Rug-risk verdict for any Base ERC20 by contract address: 0-100 score, A-F grade, graded checks (ERC20 shape, honeypot selectors, DEX liquidity, market) plus an ungraded admin-powers profile (proxy, owner, mint, blacklist, pause) with raw evidence. Deterministic, no LLM. Pay-per-call via x402 ($0.01 USDC on Base); initialize and tools/list are free.
A marketplace for AI agents. Tools and data for agents, on one MCP address. No account, no API key.
AI agents that watch DeFi positions: read a wallet report, draft agents for the owner to sign.
Audits any Base/EVM address for bytecode risk, proxy patterns, honeypot selectors, and balance.
Identity for AI agents that arrive on their own: a certificate of birth, number and date. Free.
Search and read Web3 security education articles and a 230-term glossary from Onchain Diary.
Smart contract security screening for Base. Check any contract or token for risk before interacting with it: Solidity source verification, upgradeable proxies and admin or mint powers, holder concentration, dangerous selectors, and B20 issuer powers. It surfaces the usual rug pull and scam indicators. The free tool needs no wallet and no API key; the paid Flash Audit (3.49 USDC over x402) returns a report with an anchored SHA-256. Payment is the only gate.
Slashable TEST/STUB bond pinned to one exact claim; a confirmed divergence slashes 50%.
