Crypto assets are currently trading on platforms and “exchanges” that are not registered with the SEC and are not FINRA members. In contrast, our "Qualified Custodian"* is a FINRA member and SEC-registered broker-dealer that uses advanced technologies to clear, settle, and custody crypto assets subject to federal securities laws.
Through our "Qualified Custodian,"* your assets will be subject to many of the protections often seen in traditional securities trading, including the safekeeping of assets and SEA books and records reporting along with the separation between Prometheum and customer funds pursuant to SEA 15c3-3.
Regulatory uncertainty currently exists for institutions trading on or planning to trade on crypto exchanges. ProATS was built as a solution to this problem, allowing institutions to access and trade crypto assets on a federally registered platform.
Our Alternative Trading System (ATS) employs a robust trade monitoring and surveillance system that uses predetermined parameters and dynamic triggers to identify suspicious and/or malicious activity.
Prometheum is building a crypto asset ecosystem that’s fast, scalable, and reliable for many types of trading strategies. In addition to our web-based trading system, our APIs will provide seamless integration for algo traders and in-house front ends.
Prometheum ATS’s trading APIs allow subscribers to connect directly to our trade gateway to place, cancel and review orders as well as receive market data. Our APIs are presented via a modern, high-throughput WebSocket interface secured via your Prometheum ATS account.
By connecting the Prometheum ATS Trade API you can ensure the most direct connection with your own systems — including internal or third-party front ends, order routing, and algorithmic trade systems. The ProATS Trade API supports all of the order types available on the system and allows for direct real-time data to feed into your system.
