1. Empirical Four-Axis Grading Methodology
Consumer privacy and cryptocurrency comparison sites routinely rank products by marketing claims while earning 30% to 70% affiliate commissions from the very VPNs, data-removal subscriptions, and closed-source hardware wallets they review. That economic model rewards sensationalism and conceals subtle architectural flaws such as unproxied JSON-RPC batch balance queries, unverified browser-extension supply chains, or closed-NDA Secure Element firmware.
DT.gl grades systems across four reproducible engineering axes stored in version-controlled YAML datasets under
src/content/datasets/:
| Evaluation Axis | Observable Verification Evidence Required | Disqualifying Failure Conditions (Grade C or Below) |
|---|---|---|
| 1. Cryptographic & Silicon Auditability | Published primitive specs (NIST FIPS / RFC / EIP), open-source reproducible firmware builds, independent audit reports, open Secure Element architecture (`TROPIC01` or verifiable dual-chip anti-klepto) | Proprietary unreviewed ciphers, closed server-held cloud chat keys presented as private, or non-reproducible desktop/mobile wallet binaries |
| 2. Signing Display & Orchestration Fidelity | Native `ERC-7730` clear-signing descriptors, full `PSBTv2` input/output path verification, explicit `Safe` `operation=1` `DELEGATECALL` and `EIP-7702` `0x04` warnings on trusted screen | Routine blind-signing fallback of opaque 32-byte hashes on high-value multisig or token-approval calls |
| 3. Default Network & Metadata Hygiene | Cold-launch packet inspection confirming zero unauthorized analytics beacons, Tor/Oblivious relay or local node support, per-account RPC isolation, QNAME minimization, and zero ECS leakage | Batching all derived wallet addresses in a single unproxied default RPC HTTP request or transmitting crash telemetry containing user identifiers |
| 4. Supply-Chain & Physical OPSEC Resilience | Subresource Integrity (`SRI`), deterministic release signatures, minimal retention of customer shipping/KYC PII, and statutory deletion compliance | Unpinned live CDN script imports in wallet connectors or indefinite retention of buyer home-address databases |
2. Verifiable Client-Side Zero-Telemetry Engineering
Whenever DT.gl provides an interactive diagnostic or cryptographic utility in the Verification Workbench, we treat user input as adversarial-sensitive material. Rather than
asking visitors to trust a legal privacy policy, our five offline secret-handling and file-sanitizing sandboxes
enforce strict HTTP Content-Security-Policy headers at the Cloudflare edge:
Content-Security-Policy: default-src 'self'; script-src 'self'; style-src 'self'; img-src 'self' data:; font-src 'self'; connect-src 'none'; form-action 'none'; frame-ancestors 'none'; base-uri 'none'
Under connect-src 'none', Chromium, Firefox, and WebKit block every outbound network API
(fetch, XMLHttpRequest, navigator.sendBeacon, WebSocket, and EventSource) after initial static asset delivery. In addition, our Astro 5 build compiles external
stylesheets (inlineStylesheets: 'never') and omits analytics tags on all offline tool routes so
network isolation is 100% verifiable in Developer Tools.
3. Domain Lineage, Non-Affiliation & Archival Citation Stewardship
Transparency regarding domain provenance is essential to institutional trust:
- Historical Domain Usage (2020-2025): Between 2020 and 2023,
dt.glfunctioned as an alternate Ghost CMS domain and shortener for the privacy and decentralization publication Decentralize.Today, and between 2023 and 2025 as a federated Mastodon server before expiring. - Independent Ownership & Non-Affiliation: DT.gl (Digital Trust & Threat Lab)
is an independent technical specification and security research organization. We have zero
corporate, editorial, financial, or authorial affiliation with
decentralize.todayor its former contributors, and retired federated user handles (/@*) return permanentHTTP 410 Goneresponses. - Public-Interest Link Preservation: Forensic review prior to launching DT.gl identified 61
historical editorial paths cited by enduring public references, including a U.S. House Committee on the Judiciary staff report on commercial cell-phone location data, English Wikipedia software articles (Briar, Conversations), GNU Jami documentation, and engineering discussions on Hacker News, Lobste.rs, and Tildes. To
prevent dead scholarly and encyclopedia links without misrepresenting authorship, those 61 legacy URLs resolve
via single-hop redirects to dedicated
#archive-*provenance cards inside our seven flagship hubs, explicitly crediting the historical 2020-2022 citation context alongside our independent 2026 laboratory benchmarks.

Original datasets compiled by DT.gl, including the CWE Cryptocurrency Incident Dataset (JSON) and CSV export, are licensed under Creative Commons Attribution 4.0 International (CC-BY 4.0). When citing empirical benchmarks or
incident classifications, attribute DT.gl Digital Trust & Threat Lab with the canonical URL and
verification date shown in the page Revision Ledger.

5. Laboratory Testbed Environment & Reproducibility Protocol
To ensure every empirical grade published on DT.gl can be reproduced independently by external security engineers, our evaluations follow standardized instrumentation procedures across hardware, mobile operating systems, and network transport layers:
- Network Telemetry & RPC Capture: Companion wallet desktop and mobile applications are launched inside isolated VLAN namespaces routed through transparent packet capture and TLS-inspection harnesses (where certificate pinning is absent) or passive DNS/IP flow collectors (where pinning is enforced). We record cold-boot connection counts, default JSON-RPC batching behavior across 5+ derived BIP-44/BIP-84 accounts, EDNS Client Subnet leakage, and crash-reporting SDK endpoints before any user opt-out toggle is touched.
- Hardware Signer & Clear-Signing Stress Testing: Hardware wallets are tested against
adversarial payloads modeled on real-world exploits: nested
SafeexecTransactioncalls withoperation = 1(DELEGATECALL) disguised under benign inner selectors,Permit2batch approvals with far-future expirations, vanity-poisoned recipient addresses differing only in middle bytes, andEIP-7702Type-0x04 authorization tuples withchain_id = 0. Devices that fall back to blind hex digests on high-risk operations cannot receive anA-tier signing fidelity score regardless of Secure Element certification level. - Mobile OS & Browser Isolation Verification: Hardened Android builds are evaluated on
Verified Boot cryptographic root-of-trust support with relocked bootloaders, hardware memory tagging
(
ARMv9 MTE) enforcement, sandboxed privilege boundaries, cellular baseband hardening toggles, and time-to-patch parity against monthly upstream Android Security Bulletins. Browser builds are audited across Canvas, WebGL, AudioContext, font enumeration, first-party state partitioning, and cold-launch outbound telemetry sockets. - Living Errata & Vendor Neutrality SLA: Vendors may submit public git commit links or signed firmware release notes when a previously documented telemetry leak or blind-signing gap is remediated. Upon independent verification by DT.gl engineers, the corresponding YAML dataset entry and specification Revision Ledger are updated at zero charge, maintaining a transparent historical audit trail of ecosystem progress.
