Introduction to BlockchainAnalysis.io

BlockchainAnalysis.io is a blockchain compliance, tax, and audit platform designed for organizations that need to assess, monitor, and report on the risk exposure of blockchain addresses, transactions, and entities. It combines 4.2B+ verified on-chain addresses with a proprietary database of 49M+ labeled entities and real-time analysis across 38 supported blockchains to deliver institutional-grade risk intelligence.

The Three Pillars

BlockchainAnalysis.io is built around three interconnected pillars that together provide end-to-end coverage for digital asset risk management.

1. Compliance

The Compliance pillar is the core of the platform. It enables organizations to meet regulatory obligations under AML/CFT frameworks across 32+ jurisdictions.

Key capabilities:

• Wallet Screening — Submit any blockchain address and receive a comprehensive 12-section risk report covering entity identification, sanctions exposure, source-of-funds analysis, DeFi interactions, mixer usage, and more.
• Risk Scoring — Every screened address receives a deterministic risk score from 0 (lowest risk) to 100 (highest risk), calculated from 11 independently weighted risk factors.
• Address Pre-Check — Every address submitted is first verified against 4.2B+ known on-chain addresses across 9 major networks (BTC, ETH, LTC, DOGE, TRON, Polygon, Arbitrum, Optimism, Avalanche). Unknown or invalid addresses are flagged instantly before a full screening is performed.
• Entity-Aware Analysis — The platform does not analyze addresses in isolation. It links addresses to known entities (exchanges, protocols, mixers, sanctioned actors) using a continuously updated database of 49M+ labeled addresses.
• Transaction Monitoring — Continuous monitoring with configurable alert thresholds for ongoing compliance obligations (Travel Rule, suspicious activity reporting).
• Sanctions Screening — Cross-reference against OFAC SDN, EU Consolidated List, UN Security Council sanctions lists, and other jurisdiction-specific lists, updated within hours of publication.

2. Tax

The Tax pillar provides automated tax reporting for digital assets, supporting the complex scenarios that arise from DeFi, NFTs, staking, and cross-chain activity.

Key capabilities:

• Cost-Basis Calculation — Automatic computation using FIFO, LIFO, HIFO, and specific identification methods.
• DeFi Gain/Loss Tracking — Handles liquidity provision, yield farming, lending, and borrowing across supported DeFi protocols.
• NFT Tax Events — Tracks minting, buying, selling, and royalty income from NFT activity.
• Jurisdiction-Aware Reporting — Generates reports tailored to the tax rules of 32+ jurisdictions, including IRS (US), HMRC (UK), BZSt (Germany), ATO (Australia), and more.
• Export Formats — CSV, PDF, and direct integrations with major tax filing software.

3. Audit

The Audit pillar provides forensic-grade tools for auditors, regulators, and internal compliance teams that need to verify fund flows, reconstruct transaction histories, and produce evidence-grade documentation.

Key capabilities:

• Fund-Flow Reconstruction — Trace the complete path of funds from origin to destination across multiple hops, chains, and bridges.
• Proof-of-Reserves Verification — Verify that custodial entities hold sufficient reserves against customer deposits.
• Audit Trail Export — Generate tamper-evident, time-stamped audit logs suitable for submission to regulators.
• Cross-Chain Tracing — Follow fund flows that traverse bridges between supported chains.
• Historical Analysis — Reconstruct the complete transaction history of any address at any point in time.

Who Is It For?

BlockchainAnalysis.io is designed for organizations and professionals with regulatory, compliance, or fiduciary obligations related to digital assets.

Virtual Asset Service Providers (VASPs)

Exchanges, custodians, payment processors, and other VASPs subject to AML/KYC requirements under FATF guidance. BlockchainAnalysis.io helps VASPs screen customer deposits and withdrawals, monitor ongoing transaction activity, and meet Travel Rule obligations.

Cryptocurrency Exchanges

Centralized and decentralized exchanges that need to perform pre-trade and post-trade compliance checks. The platform integrates via REST API for automated screening at scale.

Hedge Funds and Asset Managers

Digital asset funds that need to demonstrate compliance to LPs, auditors, and regulators. The Tax and Audit pillars provide the reporting infrastructure required for fund administration.

Compliance Officers

Individuals responsible for building and maintaining AML/CFT programs within crypto-native organizations. The platform provides the tooling to implement risk-based approaches as recommended by FATF and required by most national regulators.

Auditors and Forensic Investigators

External auditors, forensic accountants, and law enforcement analysts who need to trace fund flows, identify counterparties, and produce court-admissible documentation.

OTC Desks and Brokers

Over-the-counter trading desks that handle large-value transactions and need to verify the provenance of funds before executing trades.

Key Differentiators

| Feature | BlockchainAnalysis.io | |---|---| | Address Verification | 4.2B+ verified on-chain addresses across 9 major networks | | Entity Database | 49M+ labeled addresses linked to known entities | | Blockchain Coverage | 52 chains (EVM, UTXO, Solana, NEAR, Cosmos ecosystem, Move-based, TON, XRP, Stellar) | | Risk Score | 0-100 deterministic score with 11 transparent factors | | Report Depth | 12 sections per screening report | | Screening Channels | Web dashboard, REST API, Telegram Bot (@BA_ScreenBot) | | Jurisdiction Coverage | 32 jurisdictions, 228 regulatory rules | | Entity-Aware Scoring | Links addresses to entities, not just raw on-chain data |

Architecture Overview

BlockchainAnalysis.io operates on a multi-layer architecture:

1. Data Ingestion Layer — Indexes raw blockchain data from all 38 supported chains via full archive nodes and third-party indexers.
2. Address Verification Layer — Pre-checks every address against 4.2B+ verified on-chain addresses using bloom filters for instant validation (sub-millisecond lookups).
3. Entity Resolution Layer — Maps raw addresses to known entities using heuristic clustering, public attribution data, proprietary intelligence, and community-sourced labels (49M+ entities).
4. Risk Engine — Computes risk scores by evaluating 11 factors against the resolved entity graph and on-chain transaction patterns.
5. Reporting Layer — Generates structured reports (12 sections) with human-readable summaries and machine-parseable JSON output.
6. Delivery Layer — Serves results through the web dashboard, REST API, and Telegram bot.
