# Collateral Management

iTRY uses a combination of an onchain vault and a regulated custody provider to manage collateral.

The majority of collateral is secured by [Zodia Custody](http://zodia-custody.com/), a licensed 3rd party custodian, where it benefits from institutional security controls, operational safeguards, and established risk-management practices. A limited portion is held onchain in the Fast Access Vault smart contract to support instant redemptions.

This hybrid custody model is designed to balance usability and security. The Fast Access Vault facilitates instant redemption and ensures a portion of collateral remains available in the rare event of custodial downtime, while regulated custody supports controlled settlement for larger redemptions and provides institutional-grade operational rigor.

This design allows routine redemptions to settle instantly while ensuring that higher-value redemptions remain fully supported by regulated custody infrastructure.
