Cross-Chain Data Infrastructure

The Cross-Chain Data Infrastructure is the foundational layer that enables RankChain to aggregate, normalize, and analyze wallet behavior across multiple blockchain networks. This system is designed to be scalable, modular, and optimized for real-time data extraction.

At its core, the infrastructure consists of a set of chain-specific indexers that interface directly with full nodes and RPC endpoints across supported networks — including Solana, BNB Chain, and Ethereum. These indexers subscribe to on-chain event logs, transaction traces, and internal contract calls to capture a wide range of behavioral signals.

Once raw data is retrieved, it passes through a unified data transformation pipeline, which performs:

• Address normalization and cross-chain identity mapping

• Protocol categorization to classify interactions (e.g., swap, lend, mint, stake)

• Time-series event batching for behavioral modeling over defined windows

• Anomaly detection hooks to flag outlier patterns in real time

All processed data is then stored in a high-performance, time-ordered data lake optimized for querying by the AI engine and search modules.

The architecture is chain-agnostic and modular, allowing new networks to be added via plug-in indexer modules without impacting upstream systems. To support future composability, the infrastructure exposes GraphQL and RESTful APIs, enabling external DApps and dashboards to consume RankChain-derived wallet intelligence in a consistent format.

By maintaining a live, structured view of on-chain behavior across ecosystems, the Cross-Chain Data Infrastructure serves as the protocol’s behavioral consensus layer — powering accurate, multi-context wallet reputation scoring at scale.
