Why it leads
Why Sign Protocol ranks #1
Each strength is read from evidence on a 0–10 ladder and weighted as the published methodology states. The 32 objective points these produce (26.8 here) sit inside the score; availability, friction, trust record and measured data add the rest. Best in this ranking on 2 of 4.

What would move the rank
Each line is the ranking run again with one of Sign Protocol’s criterion scores changed and every other value held: the smallest whole-point change on that criterion that moves its rank, and where the re-run puts it. Up to 4 climbs and 3 falls are listed, smallest change first. Nothing here is a forecast.

Record watch-outs
- Every maintained mainnet deployment is an upgradeable proxy owned by one address, 0xAE45849165E17Dc555B8264dD4Ae01a3F42344e2, and eth_getCode for that address returned exactly "0x" on both Ethereum and Base on 2026-08-07 — it is an externally-owned account, not a multisig. One private key can therefore replace the attestation logic on nine mainnets at once. Separately, the documentation has been reframed around S.I.G.N.: the docs index at docs.sign.global/llms.txt is titled "# Sovereign Infrastructure for Global Nations" and describes "S.I.G.N. is sovereign-grade digital infrastructure for national systems of money, identity, and capital. Sign Protocol provides the shared evidence layer used across deployments.", so a buyer integrating the developer stack is now a secondary audience.

Facts
facts, not scoresWhat the record publishes
- Pricing
- "To fund the account balance to pay for API key usage, you can purchase credits with USDC (1 USDC = 100 Credits)." — this priced service pays for decentralized storage uploads (a base fee of "0.01" Credits per upload on Arweave, BNB Greenfield and IPFS plus a per-byte size fee, with the caveat "Please note the above fees may be adjusted without notice. All fee units are in Credits."). No protocol fee is documented for onchain attest() or revoke(); the ISP reference only offers payable variants for when a schema hook the schema owner attached expects payment, and offchain attestation via attestOffchain carries no documented charge.

What the record carries
Changes to published ranks are recorded in a ledger; every step and its cause is listed on the rank-history page. The entries below begin with the current verified snapshot, then the methodology versions whose changes applied to this category, newest first.
8 methodology entries
- 27 September 2026Current verified snapshot · methodology 2026.10.18Score 81, #1 of 7. 4 of 4 criteria scored. History starts here; earlier values are not interpolated.
- 10 October 2026
2026.10.8When nothing serves your country, the list shown for reference is the published ranking · platform-wide- fixed The reference list shown when nothing serves your country is the published order with the published scores, and a build check now fails any such list out of that order or with a score the ranking does not publish.
- fixed The explorer prints an overall rank only for a row the published ranking holds; a country entrant such as Coinbase Commerce for US merchants shows no overall rank.
- changed Published orders do not move. Country results change only where nothing serves the country: in India bill pay keeps Bitcoin Well first and now shows Strike second, as published; 35 such runs across all categories and countries now match the published list exactly.
- 10 October 2026
2026.10.6A criterion you require re-scores the rows that meet it · platform-wide- changed The explorer sends each criterion you require, at any band, as fit_required with your other answers; region, licence, chain and fact filters stay filters. On /best, a required criterion joins For you as a marked preference does, which needs your country; Overall stays the published ranking, filtered.
- added Every published criterion has a golden case as the explorer sends it (require:<criterion>), so the order a requirement gives is replayed and gated as the published order is, and a change to it needs an entry here.
- 16 September 2026
2026.09.15Dimension scores carry tenths, and eleven more categories are re-read from primary sources · platform-wide- changed Dimension scores resolve to tenths of a point (O-04b), and weightedTotal is rounded to six decimal places before the order is read. 518 published scores move across 107 categories that were not re-read; none of them moves by more than 4 points, and most move by 1.
- fixed 66 published scores change in the eleven re-read categories, against a verbatim source each. The largest moves are Reflexer RAI (−16), Beefy and Unrekt (−11), Aztec (−10) and Golem (+9) — all of them rows whose sources had moved since their last read.
- changed Published order moves in 38 of 119 categories and three #1s change: smart_contract_audits (Zellic → Certora) and travel_rule_compliance (Sumsub Travel Rule → CodeVASP) on the finer resolution, kyc_compliance (Veriff → Sumsub) on the re-read.
- added availabilitySource (O-04g): for a reader who states a country, a row whose availability in that country rests on a region tag its record gives no source for sorts below every sourced row. It is inert in every order published here, which states no country.
