How Does a DAO Ensure the Security and Transparency of an OTC Deal?

The DAO should use an audited, on-chain escrow or a smart contract-based transaction mechanism that guarantees atomic settlement (both assets transfer simultaneously or neither does). Transparency is maintained by publicizing the terms of the deal (volume, price, counterparty type) after execution, but not the execution itself.

The governance process must approve the counterparty and the terms beforehand.
