# How Metra works?

Metra enables multi-party transactional workflows between three primary roles during the primary issuance process:

1. Investor
2. Custodian
3. Issuer 

The application is designed around a single-investor deposit contract that allows for controlled fund flows through three core actions: 

● Deposit — Authorized inflow of funds into a unique investor deposit contract. 

● DvP Settlement — Delivery-versus-Payment transaction between the Investor’s and Issuer’s wallet. 

● Withdrawal — Controlled outflow of funds with multi-party authorization. 

Each critical action is governed by multi-party signatures, ensuring institutional-grade control and compliance.
