Overview#

An exchange compliance team once maintained eleven separate blockchain integrations, each with its own data format, API quirks, and maintenance burden. 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.

The Multi-Chain Support system delivers blockchain intelligence across 15+ blockchain networks through a standardised 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.

Key Features#

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

Supported Networks#

Layer 1 Networks:

  • UTXO Chains: Bitcoin, Bitcoin Cash, Litecoin, Dogecoin, Zcash
  • EVM-Compatible: Ethereum, Ethereum Classic, BNB Chain, Polygon, Avalanche C-Chain, Fantom, Cronos, Moonbeam, Moonriver, Celo, Aurora, Gnosis Chain
  • Alternative Consensus: Solana, Cardano, Polkadot, Kusama, Cosmos Hub, Algorand, Tezos, NEAR Protocol, Aptos, Sui
  • Enterprise: Stellar, Ripple XRP Ledger

Layer 2 Solutions:

Query Capabilities#

  • Address Intelligence: Balance queries, transaction history, token holdings, contract interactions
  • Transaction Analysis: Confirmation status, fee calculations, input/output parsing, memo/data extraction
  • Block Data: Height, timestamp, miner/validator, transaction count, network metrics
  • Token Operations: ERC-20/SPL/BEP-20 balances, NFT ownership, DeFi positions, staking records
  • Smart Contract Data: Function calls, event logs, state changes, contract creation history
  • Network Status: Current block height, average fees, network health, validator status

Chain-Specific Features#

  • Bitcoin: UTXO tracking, SegWit/Taproot address types, Lightning Network channel detection, Ordinals and Inscriptions
  • Ethereum: Smart contract interaction, event log parsing, gas estimation, ENS resolution, MEV detection
  • Solana: Program-derived addresses, Token-2022 support, compressed NFTs, compute unit analysis
  • Cardano: Native asset policies, staking pool information, Plutus script data, CIP metadata
  • Cosmos: IBC transfer tracking, validator analytics, governance proposals
  • Polkadot: Parachain identification, staking nominations, XCM cross-chain messaging

Investigation Use Cases#

Cross-Chain Fund Tracing#

  • Trace fund flows across multiple blockchain networks through bridges, cross-chain swaps, and multi-chain wallet activity
  • Identify when assets move between fundamentally different blockchain architectures as part of evasion strategies
  • Map connected entities across different blockchains through behavioural correlation

Multi-Chain Compliance Screening#

  • Screen addresses and transactions across all supported networks through a single integration
  • Aggregate risk exposure across multiple blockchain holdings for comprehensive portfolio assessment
  • Detect chain-hopping activity used to circumvent single-chain monitoring

Forensic Investigation#

  • Query address activity across all chains simultaneously to build complete financial profiles
  • Identify cross-chain relationships that reveal entity structures spanning multiple networks
  • Generate evidence packages covering multi-chain activity for prosecution support

Portfolio and Risk Assessment#

  • Aggregate balance and position data across all supported blockchains for complete asset visibility
  • Track cross-chain sanctions screening coverage with OpenSanctions integration
  • Monitor network health and fee conditions for operational decision-making

Open Standards#

  • Ethereum JSON-RPC: The platform communicates with EVM-compatible nodes using the Ethereum JSON-RPC interface, issuing calls such as eth_getBalance and eth_call directly to self-hosted full nodes across all supported EVM chains.
  • EIP-155 (Ethereum Improvement Proposal 155, Chain ID): Each supported EVM network is identified by its canonical numeric chain ID as defined in EIP-155, enabling unambiguous transaction replay protection and correct routing across 40+ chains.
  • ERC-20 / ERC-721 / ERC-1155 (Ethereum Token Standards): Token balance queries, transfer history, and NFT ownership resolution are implemented against the ERC-20 fungible-token, ERC-721 non-fungible-token, and ERC-1155 multi-token interfaces respectively.
  • FATF Recommendations (Financial Action Task Force): Cross-chain transaction correlation is designed to support FATF Recommendation 16 (the Travel Rule) compliance obligations, enabling originator and beneficiary data linkage for virtual-asset transfers across networks.
  • Bitcoin UTXO Model: The Bitcoin (and UTXO-compatible chain) integration natively parses Unspent Transaction Output sets, preserving input/output structures, SegWit and Taproot address types, and UTXO-based fund-flow tracing.
  • IBC (Inter-Blockchain Communication Protocol): Cosmos ecosystem integrations track IBC cross-chain transfers, mapping packet routing between Cosmos Hub and IBC-connected chains for complete cross-chain fund tracing.
  • GraphQL: All query and mutation interfaces exposed to consumers are implemented as GraphQL schemas, providing typed, introspectable access to blockchain data, transaction analysis, and wallet enrichment operations.

Compliance#

  • Single integration provides coverage across the vast majority of cryptocurrency market capitalization for AML screening
  • Cross-chain transaction correlation supports comprehensive FATF Travel Rule compliance
  • Supports Bank Secrecy Act and AML/CTF program requirements across all networks
  • Audit trail documentation for all cross-chain queries and screening decisions
  • Enterprise reliability with high-availability infrastructure and automatic failover
  • SOC 2 Type II compliant with GDPR data handling
  • TLS 1.3 encryption and DDoS protection
