argus-x402-scoring

The decision rule behind Argus: are these wallets one operator or many? Pure functions over public chain evidence. No network, no provider code, deterministic: the same evidence gives the same verdict, so anyone can re-run it.

import { assembleInput, decide, makeConfig } from 'argus-x402-scoring';

const cfg = makeConfig({ knownHubs: [EXCHANGE, FAUCET] });
const verdict = decide(assembleInput(chainId, wallet, usdcTransfers, cfg), salt, cfg);
// { tierName: 'Linked', confidence: 'high', groupSize: 10, reasons: [...] }

The rule

• S1 the wallet's first funder is not a hub and funded at least 3 wallets
• S2 identical instalments (within 1%) to at least 3 of them within 24 hours
• S3 at least 70% of them first acted on the same UTC day
• S4 at least 90% of their outflows go back to the funder or one shared address
• S5 (context) the funder first funded at least half of a context set, such as one ERC-8004 agent's reviewers

Linked = S1 plus at least one of S2 to S5. Independent = funding traced and S1 false. Unclear = everything else, including S1 alone. A shared funder alone never links wallets, hubs never link anyone, and wallet age is never an input.

"Linked" means shared funding, not wrongdoing.
