whichonewhich token is real · on Nansen

← the tool · for judges · no login, no key, no setup

Type a ticker. Fourteen tokens share the name — Nansen labels decide which one is real.

One input → one green card. The score is deterministic arithmetic over Nansen fields only — no market cap, no volume, no search rank — and every verdict ships with the full list of Nansen calls that produced it.

The 30-second path

  1. Open https://whichone.edycu.dev/?q=PEPE. Eight cards appear pending, reorder as each tgm/flow-intelligence call lands; ethereum 0x6982…1933 turns green, robinhood 0x9b09…4eb9 gets a red IMPOSTOR badge. Cold ≈ 4 s, cached ≈ 0 s.
  2. Click Every Nansen call (16) — the provenance drawer: endpoint, credits, latency, cached or live, the response fields that entered the score, and the verdict hash.
  3. Open https://whichone.edycu.dev/q/SHIB2. The tool abstains: a 3-year-old token with a Uniswap pool and a deployer tag does not get crowned on those alone.
  4. Open https://whichone.edycu.dev/api/verdict?q=PEPE — the same verdict as JSON, same hash as the CLI prints.

Hero query, livePEPE: 14 same-name tokens · 24 credits · 16 calls · 4.4 s cold · 2026-09-16 23:40 UTC · verdict 6ac53e5e811e — output verbatim in DEMO.md
Benchmark, live12 queries × 2 cold runs: cold p50 3.6 s · p95 7.2 s · warm p50 3 ms · mean 18.6 credits, max 26 per verdict; 447 credits over 306 live calls — docs/BENCH.md is the script’s output
Nansen endpointssearch/general · tgm/flow-intelligence · tgm/token-information · tgm/holders — every term in the score is one of their response fields
Tests126 tests (vitest), each regression test named for the defect it pins · 50,000 generated cases on the decision function (fast-check: crown rule, ranking total order, score reads no buyable field) · 10,000 generated malformed queries rejected before any network call · the server key never reaches a client (unit + E2E)
Determinism12 recorded verdicts replay offline with the same decision hash, zero network, zero credits
Clean clone → first verdict22 s of machine time (clone 2 s · install 4 s · verdict 4 s · verify < 1 s · build 8 s · tests 4 s)

Reproduce

The real path — live Nansen calls, ≤ 26 credits:

git clone https://github.com/edycutjong/whichone && cd whichone && npm install
export NANSEN_API_KEY=nsn_...        # your key from https://app.nansen.ai/api
npm run whichone -- PEPE --explain   # every term of the score, every call, the hash

CI / deterministic replay (not the product — a check that the arithmetic has not drifted):

npm run verify                       # 12/12 recorded verdicts reproduced offline, no key, no network
