Data Sources & External Links

Transparency about external links, data verification, and link tracking. Why we link to wallet sites and how to verify information.

Summary: Transparency about external links, data verification, and link tracking. Why we link to wallet sites and how to verify information.

Wallet Radar links to outside sites. This page says why, how links are tagged, and how we check data.

Types of external links

Official product sites

Examples: trezor.io, ledger.com, coldcard.com, keyst.one, bitbox.swiss.

We link them so you can verify features, download from the real source and tell real sites from fakes. We avoid redirect URLs, shortened links, look-alike domains and unofficial mirrors.

GitHub repositories

Examples: trezor-firmware, ledger-live, rainbow, metamask-extension.

We link them to check open-source claims, track commits and releases, and show community activity (stars, issues, forks). GitHub is the canonical source for open-source code.

Research and reference sites

Examples: Etherscan, WalletBeat, chainlist.org, ethereum.org, walletconnect.com. We use them for independent data checks and standards (EIPs).

WalletBeat data attribution

Some wallet rows (added 2026-10-10: Bitget Wallet, Gem Wallet, Mt Pelerin / Bridge Wallet, NuFi, PillarX, Zeus, imKey Pro) use facts from WalletBeat data/ files: account types, platform variants, licence, audits, bug-bounty platform, funding flags and hardware-wallet support.

Snapshot used: commit 82e3036aba53d8dd13a55f42089ba09c44afa8c5 (2026-10-10). Licence text: https://github.com/walletbeat/walletbeat/blob/82e3036aba53d8dd13a55f42089ba09c44afa8c5/LICENSE. WalletBeat's bundled data/coinspect/ is CC BY 4.0 and is not used here. Per-wallet source URLs are in the verification log.

Official accounts, GitHub profiles and forums. We link them as alternative ways to check a project is real.

Link attribution: utm_source

External links may carry utm_source=walletradar&utm_medium=comparison.

You see https://trezor.io/.
Your browser opens https://trezor.io/?utm_source=walletradar&utm_medium=comparison.

Why: the site you visit can see the traffic came from Wallet Radar, and we do not hide that we are the referrer. The parameters are visible in the address bar, collect no personal data, and you can delete them without breaking the page.

If a link ever has a commercial relationship, we disclose it on the page. It never affects method, ranking or inclusion.

Data accuracy

How we check

GitHub activity: repository scripts against the GitHub API. A weekly GitHub Action opens a PR with fresh activity data.
Official sites: prices, fees, licences and features are checked by hand against the vendor's own pages.
Audits: taken from published reports.
Feature claims: cross-checked with official docs.

How often

Comparison tables: rechecked in reviewed passes. The last full pass was 2026-10-17. Each table shows its own "Last Updated" date.
Activity data: weekly (Action PR, reviewed before merge).
Security information: updated when we learn of it.

What we could not confirm is marked UNVERIFIED in the data. The reasons are in the verification log.

Status icons

✅ Active or verified
⚠️ Verify: needs manual confirmation, or activity is slow
🔄 Launching: not released yet
❌ Inactive, defunct or not available

Always confirm on the official site before you decide.

Safe link checklist

Before you click any external link:

Read the URL in the address bar, not the link text.
Check the domain is the official one.
Look for HTTPS.
Be wary of any URL that does not match its link text.

Warning signs: "click here" links to unrelated sites, requests for passwords or seed phrases, shortened URLs, look-alike domains (trezor-official.com instead of trezor.io), sites that copy a wallet's setup screen.

Our practice: official domains only, no shortened URLs or redirects, no credential collection, no copies of wallet login or setup pages, open-source code you can audit.

Sidecar attributes (`data/attributes.json`)

Unscored, per-value-sourced attributes live outside the scored tables, so score columns and sync_table_scores.js are untouched. Wallets get bug_bounty, reproducible_build and chain_verification. Cards get card_network and kyc_requirement. data/attributes.schema.json defines each attribute: what it applies to, allowed values (including unknown) and the required source fields.

Every value carries source_url, retrieved and source_kind. Unsourced values are left out. Sources:

WalletBeat data, pinned at the commit above.
WalletScrutiny verdict string and link only. Its review text has a separate licence, so none is copied.
Issuer pages, for cards.

Competitor and blog sites are not sources. tests/attributes.test.ts validates the data and that every key matches a table row. The site shows these values as badges.
