ChainChoice Datasets

The published rankings

Every category's published order: each product's rank, score and dimension scores, the weights, and the formula and constants that rebuild every score from this file alone. Its digest, by the recipe in the usage notes on /datasets, is the one every page footer prints.

The methodology version that computed every score.

Rankings ledger

Every change to the published order since the ledger began, one entry per line: what moved, why, and the digest each published rankings.json had. Each entry carries the SHA-256 of the line before it, and the head file names the last entry and its hash, signed with the receipt key by a build that holds it.

The number of entries on the ledger, which only grows.

Evidence files

Per category, the quoted evidence behind each criterion score: the quote, the address it was read on and the day it was read, for every product with a verified research record.

The newest day any evidence in these files was read.

Review calendar

When each category's evidence is next due for a re-read under its published review cadence, from the oldest read date among its rows; the build fails when a category is past its due date.

The day the calendar was computed from the read dates.

Build record

The build the site was made from: its commit, the rankings digest it ships, and every build check with its exit status in that chain. Its SHA-256 is not printed on /datasets: the build's last step rewrites the file after the page is rendered and records the hash in /data/datasets.json.

The commit the build was made from.

Refusals

Every product a category assessed and did not rank, with the reason its page publishes, a source where the record or the reason names one, and the day the public universe ledger first recorded it.

The day the list last changed.

Organizations

The operating entities behind every product placed in a category: each organization with its catalog ids, the categories each is placed in and the products it collapses to. The count is an upper bound, and the file says why.

The day the map last changed.

Corrections

Every published correction: what was wrong, what was fixed, how it was caught and whether the published order moved, newest first, as /methodology/corrections prints it. The same entries are in the Atom feed at /api/feed.xml.

The newest entry in the log.

Pricing ledger

The append-only ledger of structured pricing facts: one line per fact, appended when its value changes, with the day it was observed. /methodology/data-changelog renders it; data/observations/index.json carries its licence and hash.

The number of observations on the ledger, which only grows.

Universe ledger

The append-only ledger of placements and named refusals: one line per state, appended when it changes, with the day it was observed. /methodology/universe renders it, and /data/refusals.json dates each refusal from it.

The number of observations on the ledger, which only grows.

Search query corpus

Every labelled query the search bars are measured on, with the page or address each must open: names, misspellings, sentences with constraints, plans of several steps, and questions as buyers ask them. Its file search-quality.json publishes the rate of each kind, misses included; the build replays every kind and fails when the file is not the replay.

Hand-labelled sentences and questions the search bars open right, of all of them, as the build replayed them (the generated cases are counted apart in the file).

Partner programmes

Every partner programme on record, with its state, its network and the days its state changed, generated from the record the outbound links read. Commission terms are not in it.

The day the record last changed.

The ChainChoice ranking engine described as data: the scoring dimensions, the formula, the version, the rankings feed it produces and the separation between the ranking and commercial terms. Anyone reproducing a rank reads this first.

Affiliate-blind editorial index scoring how ready each major US-serving crypto exchange is to register under the CLARITY Act's SEC/CFTC regime (DCM/ATS), across six weighted dimensions. Per-exchange, per-dimension scores. CC-BY-4.0. Updated as registrations land.

Affiliate-blind editorial index of how well-positioned each major EU-serving crypto exchange is under MiCA's CASP regime, across six weighted dimensions. Per-exchange, per-dimension scores. CC-BY-4.0. Verifiable against the ESMA register.

Affiliate-blind editorial index of how transparent the major crypto exchanges are about reserves, audits, custody, and disclosure, across six weighted dimensions. Per-exchange, per-dimension scores. CC-BY-4.0.

All decision categories ChainChoice covers (exchange, wallet, tax-software, lending, staking, crypto-card, onramp, payment-gateway, stablecoins, bridges, portfolio-tracking, web3-apps) with provider counts and active-question dimensions.

EU member states + MiCA-adjacent jurisdictions with regulator details (BaFin, AMF, CNMV, FCA, FINMA…), transitional-window dates, and tax-framework references. Used by every country-guide surface.

Total value locked per Ethereum Layer-2 (Arbitrum, OP Mainnet, Base, zkSync Era, Starknet, Polygon zkEVM, Scroll, Linea, Blast), fetched from the DefiLlama public API on each deploy. Dated and sourced; overlaid on the L2 comparison for context — the ranking scores permanent architecture, never TVL.

These live figures are paused while ChainChoice asks DefiLlama for written approval to show them.

Total value locked per decentralized exchange (Uniswap, Curve, PancakeSwap, Balancer, Aerodrome, Raydium, SushiSwap, Maverick), parent-protocol aggregation fetched from the DefiLlama public API on each deploy. Dated and sourced; overlaid on /best/dex for context — the ranking scores security & track record and decentralization, never TVL, because TVL measures adoption, not safety.

Total value locked (collateral + liquidity) per perpetual-futures DEX (Hyperliquid, GMX, dYdX, Jupiter, Drift, Gains, Aster), fetched from the DefiLlama public API on each deploy. Open interest is not exposed keylessly, so TVL is the dated size metric. Dated and sourced; overlaid on /best/perp_dex for context — the ranking scores security & track record and decentralization, never TVL, because value locked measures adoption, not safety.

Live staking yield per provider (Lido, Rocket Pool, Coinbase, ether.fi, Swell, Stader, Puffer) from each issuer's canonical DefiLlama pool — pinned by exact project + token symbol + chain (base yield where available, per-row metric). Liquid-restaking tokens are flagged. Dated and sourced; overlaid on /best/staking for context — never scored, because ETH liquid-staking yields cluster closely and cross-asset yields are not comparable.

Live USDC supply APY for the DeFi money markets that expose a single canonical protocol-level supply pool (Aave, Compound, Fluid, Venus) from each protocol's canonical DefiLlama pool — pinned by exact project + token symbol + chain (apyBase base supply rate where available, per-row metric). A variable rate that floats with utilization. Intentionally omitted because they have no single comparable protocol-level supply rate: isolated-market & vault-aggregator protocols (Morpho, Kamino, Euler, Curve, Silo — rate is vault/market-specific), CeFi (Nexo/Ledn), RWA credit (Maple/Goldfinch), fixed-rate and yield-tokenization protocols. Dated and sourced; overlaid on /best/lending_borrowing for context — never scored, because a money market is ranked on credit model, liquidity, collateral flexibility and counterparty confidence, and a higher rate is usually compensation for higher risk.

The receipt ID every country and category page prints: the month its evidence was read and a hash of the exact list it shows. /r/<id> rebuilds today's list and says whether it still gives the same hash.

The versioned, dated affiliate disclosure surface. Pairs with the structured partnership ledger at /affiliate/receipts.

Canonical sitemap of every indexable surface — landing, methodology, country guides, compliance hubs, insights, honest reviews, recommended guides, glossary, founder corner, datasets. Updated on every deploy.

Concise, machine-targeted index pointing summarizers to the highest-value surfaces (methodology, affiliate disclosure, key reviews). Follows the emerging llms.txt convention for LLM-friendly site maps.

Expanded llms-full.txt — the complete editorial corpus serialized for LLM ingestion: methodology, country guides, compliance hubs, insights, honest reviews, glossary, all inline.

The v1 API contract: /api/v1/recommend, /api/v1/receipts and the compliance and partner endpoints, with request and response schemas and the auth model. A test that runs in every build holds each documented response to the handler that answers it.

A single-file TypeScript client for the v1 API, with no dependencies. Its types are the OpenAPI schemas, and a test holds them to the spec.
