ChainChoice Datasets

The ChainChoice ranking engine described as data: scoring dimensions, version pins, fit-vs-affiliate separation contract, and the canonical receipt JSON schema. Anyone reproducing a rank reads this first.

Pinned JSON specification of the engine methodology at each version cut. The reproducibility surface — receipts cite which version they were produced under.

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; cite freely. 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; cite freely. 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; cite freely.

All decision categories ChainChoice covers (exchange, wallet, tax-software, lending, staking, crypto-card, on-ramp, 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.

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.

JSON Feed of recently published signed decision receipts. Each entry includes the receipt ID, content hash, signing key reference, and a deep-link to the public verification surface.

Public JSON Web Key Set for verifying every signed ChainChoice receipt (decision receipts, affiliate disclosure, partnership receipts, methodology spec). Ed25519. Rotation logged in the methodology changelog.

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 full v1 API contract: /api/v1/recommend, /api/v1/receipts, compliance + partner endpoints. Includes request/response schemas, example payloads, and auth model. Generated and CI-validated.

Generated TypeScript client for the v1 API — typed request/response models, retry semantics, receipt-verification helper. Tracks the OpenAPI spec.
