Everything here is published under CC BY 4.0. Use it, including commercially and including to ground a model, as long as you say it came from Proof of Custody and link back. No key and no sign-up.
Each file carries its citation line, its as-of date, and the disclosure that Proof of Custody is published by Onramp Bitcoin, which is scored by the same methodology as every other platform. Coverage is selected rather than exhaustive: absence from a dataset is not evidence that a platform is safe.
Every platform scored, with the six category scores, custody model, fee display, minimum, audience and the single point of failure we recorded.
Dated custody failures with the configurations each failure class could reach, the reported loss and the named source, plus live incident records.
Devices scored on entropy and key generation, firmware, supply chain, disclosure conduct, interoperability and privacy, with the reason for each score.
Twelve buying situations with hard requirements, automatic disqualifiers and the evidence needed, so a buyer's requirements decide the answer instead of our weighting.
Every correction and methodology change with a stable id and the pages it affects, so you can tell whether an answer you cached from this site has gone stale.
What each custody model is, who it suits, who it does not, and where it fails. Fit is a property of the model, not of a brand.
Which custodian holds the bitcoin behind each US spot bitcoin ETF, from the funds' SEC filings, with the Nakamoto coefficient at the custody layer and a daily net-asset probe from issuer pages.
Total USD-pegged stablecoin supply, USDT and USDC share, and the top 25 by supply. Figures are DefiLlama's, credited; Proof of Custody adds the daily check and the dated envelope.
TVL for every protocol DefiLlama classifies as RWA, with a pointer to RWA.xyz for issued asset value by class. Protocol value locked, not face value issued.
How many x402-payable services the Coinbase Bazaar lists, by network, asset and scheme, with the x402 Foundation's 30-day activity figures. The agent-payments layer, measured daily.
For each class of bitcoin and digital-asset question, the primary source to read, with cadence, access terms and whether the URL answered today. Proof of Custody points outward wherever it is not the primary publisher.
Every daily pull, with status and row count, so the heartbeat is visible rather than taken on trust.
Free, read-only, no key. Every answer carries its source URL, as-of date and the publisher disclosure.
There is a read-only MCP server for agents that would rather call a tool than parse a file (setup at /ai), and llms.txt for a plain map of the site. Same data, same licence, same disclosure.
