Building with VaultX
Last updated July 2026
Overview
VaultX indexes custodial reserves for tokenized commodities and publishes verification data on Robinhood Chain. This documentation covers the reserve attestation format, the query interface used by VaultX Intelligence, and integration patterns for reading vault data on-chain.
Reserve attestations
Each custodial partner submits signed attestations on a rolling schedule. Attestations include custodian identity, asset class, quantity, storage location, and a cryptographic proof anchored to Robinhood Chain. Circulating token supply is reconciled against attestations every block.
Reading vault state
Reserve percentage, verification status, and price data for every supported commodity are readable directly from the on-chain vault registry — no API key or centralized gateway required.
VaultX Intelligence
The natural-language query layer sits on top of the same on-chain data surfaced elsewhere on this site. It's intended for research and transparency, not as a source of trading advice.
