Score: 5.7/10 (Innovation: 5, Technical: 6, Documentation: 6, Utility: 6)

Solana Index provides a REST API for querying historical SPL token balances at specific Solana slot heights, offering cached responses and deterministic data for accounting and auditing. Its slot-based approach avoids reliance on approximate timestamps, making it useful for treasury reporting and automated backend jobs. The project is a practical tool for Solana developers needing precise historical token state without running archival nodes.

Target audience: backend devs
