Unified Multi-Chain Ledger Integrator

Resilient pipeline for consolidating transactional data across multiples blockchains and contracts (EVM and Solana). I replaced third-party indexers with raw RPC extraction using 'Reverse Check' algorithms, optimizing block scanning. The core differentiator is the Auto-Reconciliation engine (Pacemaker), which continuously audits the PostgreSQL database against network nodes, ensuring strict uniqueness and 100% integrity in balances.

Case Study

Problem

On-chain data fragmentation and integrity risks when using third-party indexers across 15+ networks.

Solution

Raw RPC extraction combined with an internal auditing engine for continuous auto-reconciliation.

Impact

Canonical relational unification with absolute accuracy guarantees for transactions and cross-chain balances.
