Blockchain Transaction Analysis Platform

Overview#

During an active incident response, a cryptocurrency exchange's security team needed to know where $8M in stolen funds were moving in real time. Mempool monitoring caught the attacker's transactions before they confirmed, giving the team enough time to notify three downstream exchanges, two of which froze the incoming transfers. The difference between recovery and total loss was measured in seconds, not hours.

The Blockchain Transaction Analysis Platform provides comprehensive multi-chain transaction analysis with real-time monitoring, historical analysis, and transaction intelligence across Bitcoin, Ethereum, and 15+ blockchain networks. Compliance teams, risk analysts, blockchain investigators, and financial intelligence units query, analyse, and investigate cryptocurrency transactions with this platform, bringing together real-time mempool monitoring, cross-chain correlation, and evidence-grade documentation under a single interface.

Key Features#

• Multi-Chain Transaction Querying: Query transaction history across 15+ blockchain networks through a unified interface, removing the need for separate tools per chain
• Historical Transaction Analysis: Unlimited lookback capability enabling deep historical investigation into address activity patterns and transaction relationships
• Real-Time Mempool Monitoring: Detect and analyse pending transactions before blockchain confirmation, enabling proactive threat response
• Transaction Receipt Deep Inspection: Comprehensive analysis of transaction receipts including gas usage, event logs, internal transactions, and state changes
• Cross-Chain Transaction Correlation: Link related transactions across different blockchain networks to identify multi-chain fund movements and evasion patterns
• Transaction Flow Tracing: Visual and analytical tracing of fund flows through intermediary addresses with value tracking
• Automated Compliance Screening: Real-time transaction screening against sanctions lists, risk databases, and organisational policies
• Gas Fee Analysis: Transaction cost optimisation analysis and historical fee trend data for operational decision-making

Supported Networks#

• Major EVM Chains: Ethereum, Polygon, BNB Chain, Arbitrum, Optimism, Base, Avalanche, Fantom
• Bitcoin and UTXO Chains: Bitcoin, Bitcoin Cash, Litecoin, Dogecoin
• Layer 2 Solutions: Polygon, Arbitrum, Optimism, Base, zkSync Era, Starknet, Linea

Transaction Analysis Capabilities#

Address Transaction History#

• Complete transaction history retrieval for any address across supported networks
• Filtering by date range, value, transaction type, and counterparty
• Automatic classification of transaction types: transfers, contract interactions, token operations
• USD valuation at time of transaction and current value for gain/loss analysis

Transaction Receipt Analysis#

• Detailed inspection of transaction execution including status, gas consumption, and event logs
• Internal transaction extraction showing contract-to-contract calls and value transfers
• Smart contract method decoding for understanding transaction purpose
• Token transfer extraction from event logs across ERC-20, ERC-721, and ERC-1155 standards

Mempool Intelligence#

• Pre-confirmation transaction detection for time-sensitive investigations
• Pending transaction analysis including gas price, nonce, and replacement detection
• Alert generation for high-value or high-risk pending transactions
• Front-running and MEV activity detection in transaction ordering

Cross-Chain Correlation#

• Bridge transaction identification linking movements across different blockchains
• Timing-based correlation for transactions occurring across chains in coordinated patterns
• Multi-chain address profiling aggregating activity across all supported networks

Investigation Use Cases#

Financial Crime Investigation#

• Trace funds from initial criminal activity through complex transaction chains to cash-out endpoints
• Identify structuring patterns, layering activity, and other money laundering indicators
• Build complete transaction timelines for prosecution support with evidence-grade documentation

Compliance Monitoring#

• Screen all incoming and outgoing transactions against sanctions lists and risk databases
• Monitor transaction patterns for suspicious activity requiring SAR filing
• Generate compliance documentation with transaction-level audit trails

Fraud Detection#

• Identify unusual transaction patterns indicating account compromise or insider fraud
• Detect rapid fund movements and exchange deposits characteristic of theft cash-out
• Analyse transaction timing and counterparty patterns for coordinated fraudulent activity

Tax Investigation#

• Reconstruct complete transaction histories across multiple addresses and networks
• Identify unreported income through transaction analysis and counterparty attribution
• Calculate capital gains and losses with cost basis tracking across tax periods

Incident Response#

• Real-time monitoring of compromised addresses during active security incidents
• Rapid fund tracing to identify where stolen assets are moving
• Exchange notification support with transaction evidence for asset freeze requests

Open Standards#

• Ethereum JSON-RPC: The platform communicates directly with EVM full nodes using the Ethereum JSON-RPC specification, calling methods such as eth_getTransactionReceipt, eth_getBalance, eth_chainId, and eth_call for real-time on-chain data retrieval.
• ERC-20 / ERC-721 / ERC-1155: Token transfer events are decoded and classified according to these Ethereum token interface standards, enabling extraction of fungible token transfers, NFT movements, and multi-token operations from transaction logs.
• GraphQL: The entire analytical API surface is exposed via GraphQL, with typed queries and mutations covering transaction history, mempool monitoring, sanctions screening, clustering, forensic reports, and cross-chain correlation.
• FATF Recommendations (Travel Rule / AML/CTF): The platform supports compliance with FATF's 40 Recommendations, including automated transaction screening, suspicious activity monitoring, and SAR documentation workflows aligned with anti-money laundering and counter-terrorism financing obligations.
• OFAC Specially Designated Nationals (SDN) / OpenSanctions: Address screening is performed against the OFAC SDN list and the OpenSanctions consolidated dataset, with match status, entity name, and risk level returned per query.
• ISO 8601: All timestamps in transaction records, forensic reports, and graph visualisation data are serialised in ISO 8601 format, ensuring interoperability with downstream systems and evidence packages.
• TLS 1.3: All data in transit between clients and the platform, and between internal services, is protected using TLS 1.3 in accordance with the module's stated compliance posture.
• OAuth 2.0 / JWT (RFC 7519): Access to all analytical endpoints is governed by JSON Web Tokens issued via the platform's authorisation service, enforcing role-based access control across all transaction queries and forensic operations.

Compliance#

• Transaction data suitable for regulatory examination and audit documentation
• Supports Bank Secrecy Act, AML/CTF, and FATF Travel Rule compliance requirements
• Complete audit trail of all transaction queries and analytical activities
• Evidence-grade data with cryptographic verification linking to source blockchain transactions
• Encryption in transit (TLS 1.3) and at rest
• Role-based access control with multi-factor authentication
• SOC 2 Type II certified infrastructure with GDPR-compliant data handling
