Risk Score and Screening

8. How does the risk score work?

The BlockchainAnalysis.io risk score is a numeric value from 0 to 100, where 0 means no identified risk and 100 means critical risk. The score is computed using 11 independently weighted factors, including:

  • Direct entity match (category and threat level)
  • Direct exposure to high-risk entities (mixers, scams, sanctioned addresses)
  • Indirect (counterparty) exposure
  • Transaction pattern anomalies
  • Sanctions list matches
  • Age and activity of the address
  • Cross-chain behavior

See Risk Score for the full methodology.

9. What is the difference between a Standard and Advanced check?

  • Standard check (/check) — Returns a quick risk score (0–100), entity match, and threat level. Takes 2–5 seconds. Costs 1 standard credit.
  • Advanced check (/advanced) — Returns a full 12-section compliance report including direct/indirect exposure analysis, transaction patterns, sanctions screening, source/destination of funds, DeFi interactions, and a compliance recommendation. Takes 10–30 seconds. Costs 1 advanced credit.

See Standard vs Advanced for a detailed comparison.

10. How accurate is the data?

The Entity Database contains 49M+ labeled addresses with an average label confidence of over 95%. Data is sourced from public labels, proprietary research, partner feeds, blockchain explorers, OFAC/sanctions lists, and community reports. However, no database is 100% complete — unlabeled addresses are not necessarily safe, and labels may occasionally be incorrect. See Entity Database for more details on data sources and limitations.

10b. What is address verification?

Before running a full screening, BlockchainAnalysis.io performs an instant address verification pre-check against 4.2B+ verified on-chain addresses. This dataset, sourced from Google BigQuery public blockchain datasets across 9 major chains (Bitcoin, Ethereum, BNB Smart Chain, Polygon, Arbitrum, Optimism, Base, Avalanche, and Fantom), is stored in a bloom filter that confirms whether an address has ever appeared on-chain — in under 1 millisecond. This helps detect typos, fabricated addresses, and never-used wallets before credits are consumed on a full screening. See Entity Database — Address Verification for technical details.

Privacy and Security

11. What data does BlockchainAnalysis.io collect about me?

BlockchainAnalysis.io collects only the data necessary to provide the service:

  • Account data — Email, name, organization (provided at registration).
  • Query data — Addresses you screen and reports you generate (linked to your account for history/audit purposes).
  • Payment data — Processed by our PCI-compliant payment provider; we do not store card numbers.

We do not collect or store your private keys, seed phrases, or wallet credentials. See Data Privacy for the full privacy policy.

12. Is my screening activity private?

Yes. Your screening queries are associated with your account for reporting and audit trail purposes, but they are never shared with other users, sold to third parties, or made public. Enterprise customers can configure data retention policies.

13. Do you support Two-Factor Authentication (2FA)?

Yes. We strongly recommend enabling 2FA on your account. BlockchainAnalysis.io supports:

  • TOTP (Time-based One-Time Password) — Compatible with Google Authenticator, Authy, and other TOTP apps.
  • Hardware security keys — FIDO2/WebAuthn support for YubiKeys and similar devices.

Enable 2FA in Settings > Security > Two-Factor Authentication.

Telegram Bot

14. How do I use the Telegram bot?

Open Telegram and search for @BA_ScreenBot or go to t.me/BA_ScreenBot. Send /start to begin, then use /check [address] for a standard check or /advanced [address] for a full report. See Telegram Bot Getting Started for a complete guide.

15. How does chain detection work for EVM addresses?

Since EVM addresses (starting with 0x) are valid across multiple chains (Ethereum, BNB Chain, Polygon, Arbitrum, etc.), the bot displays an inline keyboard after you submit an EVM address, allowing you to select the specific chain you want to check. Non-EVM addresses (Bitcoin, Solana, Tron, etc.) are detected automatically from their format.

Reports and Exports

16. What format are reports in?

Reports can be downloaded in multiple formats:

  • PDF — Formatted, print-ready reports suitable for regulators, auditors, and clients.
  • CSV — Machine-readable format for import into tax software, spreadsheets, or internal systems.
  • JSON — Available via the API for programmatic access and integration into compliance workflows.

17. Can I share a report with my auditor or regulator?

Yes. You can generate a secure, time-limited sharing link for any report. The link can be set to expire after a configurable period (e.g., 7 days, 30 days) and can optionally require a password. Enterprise customers can also white-label reports with their organization's branding.

Compliance and Regulations

18. What compliance requirements does BlockchainAnalysis.io help with?

BlockchainAnalysis.io helps organizations comply with:

  • AML/KYC — Anti-Money Laundering and Know Your Customer obligations through wallet screening and transaction monitoring.
  • FATF Travel Rule — Identify originators and beneficiaries of virtual asset transfers.
  • OFAC sanctions — Real-time screening against US Treasury OFAC SDN list and other global sanctions lists.

  • MAS (Singapore) — Monetary Authority of Singapore payment services compliance.

19. What jurisdictions are supported for tax reporting?

Tax reports can be generated for 32+ jurisdictions, with jurisdiction-specific rules for cost basis methods, holding period classification (short-term vs long-term), and tax-free thresholds. Supported jurisdictions include the US (IRS), UK (HMRC), Germany (BZSt), Australia (ATO), Canada (CRA), Singapore (IRAS), and many more. See Supported Jurisdictions for the full list.
