nc://token-safety

Grey Ridge token safety: a pre-trade check on a Base ERC-20 — a honeypot, a measured transfer tax, the owner and mint flags, the liquidity, and one verdict. A Nodecode rewrite of rezearcher/greyridge-token-safety-skill by rezearcher.

Get it

Tell the agent "add the token safety cell", or run nodecode add nc://token-safety.

Set it up

One setting, no key, no account: api_base is the API root the report is asked from. Paste

https://x402-data-api.sigrunner.workers.dev

in /settings, or set it in one line:

(config-set '("token-safety") '(:api_base "https://x402-data-api.sigrunner.workers.dev"))

Then (restart-cells "nodecode-token-safety"). The free preview needs no key and no signup; it is metered at three real-token checks a day per address, and every answer says so.

Use it

Ask the agent "is this Base token safe?" with the address, or call the tools yourself:

• token_safety {token} — the full report: whether a sell goes through (a honeypot reverts it), the transfer tax measured on a plain transfer, ownerRenounced, canMint, canPause, hasBlacklist, upgradeableProxy, the Uniswap v3 WETH-pool liquidity in dollars, and a verdict (SAFE / CAUTION / AVOID) with a risk_score and its reasons.
• swap_gate {token, side, notional_usd} — the same checks sized into a go / hold / block decision for one trade.

A person types /token-safety 0x… for the verdict and its reasons in chat, and eval reads the same answer:

(token-safety:report "0x4200000000000000000000000000000000000006")
(token-safety:gate "0x4200000000000000000000000000000000000006" :side "buy" :notional-usd 500)

Read the verdict plainly: AVOID means do not trade and tell the user why; CAUTION means tradeable with risk, so show the reasons and let them decide; SAFE means no trap these checks find, which is not a guarantee. Base (chain 8453) only, the DEX buy/sell tax is not measured (it reads null), liquidity is the Uniswap v3 WETH pool only, and the report is a heuristic from a third-party service, not financial advice.

What it talks to

The Grey Ridge x402 API at the api_base the section names: GET /chain/token-report/preview?token=0x… and GET /gate/swap/preview?token=0x…&side=buy&notional_usd=500. The token address, the side and the size are the only things sent, and the only things the cell knows. Every answer carries the API's paid route in paid_route (0.01 USDC a call through an x402 client on Base); this cell does not pay it.
