Data methodology
How the portal separates product inventory, source-linked websites, availability, and missing metadata.
Preserve the inventory
The directory contains all 969 supplied records. The 358 wallet entries and 667 wallet-tool entries share 56 matches; same-name variants with different descriptions stay separate. Category placement and historical collection positions are not rankings.
Follow an explicit website link
The URL audit uses the directory profile’s “Visit website” anchor, not an inferred domain, a search advertisement, or a related product card. The source-linked URL and any observed redirect destination are recorded separately. Only supported, non-intermediary targets become public project links.
Do not turn a failed fetch into a factual conclusion
Some source pages could not be retrieved. Some destinations time out, block automated clients, or render primarily through scripting. These conditions are logged separately from an absent link. A blank official URL is an unresolved field, not proof that a product does not exist. Parked domains, unrelated redirects, and identified missing pages are withheld.
See exact coverage: 762 published URLs and 207 blank fields.
Distinguish the audit from full first-party metadata extraction
Browser-assisted retrieval and click-through observations supply the current URL audit; Python joins the records, updates static pages and feeds, and validates the package. Original descriptions and source metadata are preserved, but this pass does not claim a complete first-party HTML, meta-tag, or JSON-LD crawl. Empty fields stay empty.
Images and original observations
Every optimized website image is preserved byte-for-byte. The image downloads include the original source image files, renamed to descriptive SEO filenames with a hash manifest. A chain-icon strip or additional-chain badge is not a complete list of supported networks. Source graphics are not recast as official logos.
Public resources and private maintenance
The public portal contains direct product links, product metadata, and image/data downloads. Research PDFs and intermediary URLs are not public resources. The separate maintainer package contains source-level evidence, original metadata, unresolved cases, and a resumable Python collector for a network-enabled environment.
Editorial content
Wallet Field Notes articles, publication dates, layout, and images are unchanged. Editorial examples are not product ratings or independent security assessments.
