When a new chain gained traction, adding support meant months of engineering work. The multi-chain support infrastructure replaces that fragmentation with a single, consistent interface across 15+ networks, from Bitcoin's UTXO model to Ethereum's smart contract ecosystem to Solana's program-derived addresses.\n\nThe Multi-Chain Support system delivers blockchain intelligence across 15+ blockchain networks through a standardized API. Designed for cryptocurrency exchanges, financial institutions, compliance teams, and blockchain analytics platforms, this infrastructure removes the complexity of managing multiple blockchain integrations. The system abstracts chain-specific details while preserving native features, enabling investigators and developers to query Bitcoin, Ethereum, Solana, and dozens of other chains through a consistent interface.\n\n```mermaid\ngraph LR\n    A[Unified API] --> B[Bitcoin / UTXO]\n    A --> C[Ethereum / EVM]\n    A --> D[Solana]\n    A --> E[Cardano]\n    A --> F[Cosmos Ecosystem]\n    A --> G[Layer 2

chains, removing the need for separate integrations per blockchain\n- **Automatic Chain Detection**: Identifies the target blockchain from address format alone with high accuracy, making investigation workflows faster\n- **Universal Data Normalization**: Chain-specific responses are transformed to a consistent data model while preserving native feature access\n- **Multi-Provider Redundancy**: Connections to multiple providers per blockchain with intelligent routing, automatic failover, and health monitoring for enterprise-grade reliability\n- **Block Explorer Integration**: Direct links to 47+ block explorers with automatic network selection and correctly-formatted URLs\n- **Chain-Specific Feature Preservation**: Despite a unified API, unique chain capabilities (Bitcoin UTXOs, Ethereum smart contracts, Solana programs, Cardano staking) remain fully accessible\n- **Real-Time Network Monitoring**: Continuous tracking of block production, fee markets, network health, and chain upgrades across all supported networks\n\n## Supported Networks\n\n**Layer 1 Networks:**\n- UTXO Chains: Bitcoin, Bitcoin Cash, Litecoin, Dogecoin, Zcash\n- EVM-Compatible: Ethereum, Ethereum Classic, BNB

networks through bridges, cross-chain swaps, and multi-chain wallet activity\n- Identify when assets move between fundamentally different blockchain architectures as part of evasion strategies\n- Map connected entities across different blockchains through behavioral correlation\n\n### Multi-Chain Compliance Screening\n- Screen addresses and transactions across all supported networks through a single integration\n- Aggregate risk exposure across multiple blockchain holdings for comprehensive portfolio assessment\n- Detect chain-hopping activity used to circumvent single-chain monitoring\n\n### Forensic Investigation\n- Query address activity across all chains simultaneously to build complete financial profiles\n- Identify cross-chain relationships that reveal entity structures spanning multiple networks\n- Generate evidence packages covering multi-chain activity for prosecution support\n\n### Portfolio and Risk Assessment\n- Aggregate balance and position data across all supported blockchains for complete asset visibility\n- Track cross-chain sanctions screening coverage with OpenSanctions integration\n- Monitor network health and fee conditions for operational decision-making\n\n## Compliance\n\n- Single integration provides coverage across the vast majority of cryptocurrency market capitalization for AML screening\n- Cross-chain transaction correlation supports comprehensive FATF Travel Rule compliance\n- Supports Bank Secrecy Act and AML/CTF program requirements across all networks\n- Audit trail documentation for all cross-chain queries and screening decisions\n- Enterprise reliability with high-availability infrastructure and automatic failover\n- SOC 2 Type II compliant with GDPR data handling\n- TLS 1.3 encryption and DDoS protection\n\n**Last Reviewed:** 2026-02-05\n**Last Updated:** 2026-04-14\n"}
