Fuci Risk

Know the risk before you put money in.

A free A–F rating for any token on Arc or DeFi protocol. Every score is built from real on-chain and public data, explained in plain words, with a link to the source. When data is missing we say "Unknown" instead of guessing.

Reading the chain, pools and records… a busy new token can take up to 30 seconds.

How the grade works

  • A80+ lower
  • B65+ moderate
  • C50+ elevated
  • D35+ high
  • Fbelow 35 very high

Each check scores 0–100 (higher is safer) and the grade is their weighted average. Serious red flags cap the grade no matter how good the rest looks: a token under a week old can't score above C, an owner that can mint can't score above D, a hack in the last year caps a protocol at C.

See every check we run

  • Contract control

    Who can change the token: an owner, an upgradeable proxy, mint, pause or blacklist functions. Read straight from the contract on Arc.

  • Launch terms

    For Argus launches: the buy and sell tax fixed by the launch hook, and whether the token has bonded.

  • Liquidity

    How much sits in trading pools (DexScreener), and how that compares to the token's valuation. Thin pools make selling hard.

  • Holder concentration

    Replayed from every transfer on Arc (tokens up to 14 days old). Pools, locks and burns are left out; any other large holder counts.

  • Age & activity

    How long it has existed and how actively it trades. Most rug pulls happen in the first days.

  • Audits & security history

    For protocols: audits listed on DefiLlama and every hack in DefiLlama's database, weighted by how recent.

  • TVL, governance & yield

    Value locked and its stability, public governance, and how much of the yield is real fees versus emitted reward tokens.

Not financial advice. A rating describes risk signals we can measure; it can't see everything (team intent, off-chain deals, future bugs). A good grade is not a promise, and a low grade is not an accusation. Risk is part of investing: make it informed.
