# Custody

To deliver scalable index products, OpenDelta employs a hybrid approach, where backing assets are held and settled with institutional custodians, while tokens representing ownership shares of these assets are issued on-chain. To ensure maximum transparency and auditability, all assets are stored in segregated MPC wallets, with key shards distributed among OpenDelta, the custodian, and a trusted third party. Regular proof-of-constituents verifications enable public auditability and enhance trust. Additionally, each product’s assets are governed by a bankruptcy-remote SPV, providing further legal segregation and protection.
