# 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
