- • Prometheum Capital, a FINRA member and SEC-registered special purpose broker-dealer, received June 2025 authorization to provide correspondent clearing services—enabling third-party broker-dealers to offer crypto, tokenized securities, and onchain assets to their clients without building proprietary infrastructure.
- • The platform is the first crypto company approved by the SEC as a qualified custodian for digital assets and has begun initial custody operations with Ethereum, with plans to expand to additional digital assets and launch a full trading operation.
- • Correspondent clearing and custody services eliminate the requirement for traditional institutions to construct their own digital asset infrastructure, addressing a key barrier to mainstream financial adoption of blockchain-based securities and crypto products.

Summary
Prometheum, a market infrastructure provider for blockchain-based securities, has secured $23 million in new capital to accelerate the integration of crypto assets, tokenized securities, and onchain financial products into traditional broker-dealer networks. The funding from high-net-worth investors and institutions signals institutional confidence in Prometheum's regulatory compliance framework and its positioning as critical infrastructure for mainstream financial adoption of digital assets.
The centerpiece of Prometheum's strategy is correspondent clearing and custody services, delivered through its FINRA member subsidiary, Prometheum Capital. Following SEC registration as a special purpose broker-dealer in June 2025, Prometheum Capital was authorized to provide correspondent clearing services to third-party broker-dealers. This authorization marks a significant inflection point: broker-dealers no longer need to build proprietary custody and clearing infrastructure to offer digital assets. Instead, they can introduce client accounts on a fully disclosed basis to Prometheum Capital, which handles clearing, custody, execution, and record-keeping functions. Aaron Kaplan, co-chief executive, emphasized that this model addresses distribution as a critical bottleneck: "It is our belief that distribution is one of the keys towards the transition to digital markets."
Prometheum holds additional regulatory distinctions. It is the only U.S.-registered crypto platform approved by the SEC to serve as a qualified custodian for digital assets. The company has already begun initial custody operations with Ethereum and plans to expand to additional digital assets and launch a full trading operation. Notably, Prometheum was engineered using traditional brokerage industry standards—FIX messaging, API integration, and regulatory compliance frameworks—rather than adopting native crypto infrastructure. This design choice facilitates integration with existing broker-dealer operational and compliance systems.
The strategic logic is straightforward: institutional investors and asset managers want exposure to digital markets but lack incentive to build infrastructure independently. EDX Markets and Prometheum are both pursuing "crypto-as-a-service" models that allow traditional financial institutions to embed digital asset capabilities into their core businesses. For Prometheum, the newly raised capital will fund expanded distribution channels and deeper integration partnerships with broker-dealers across the industry. The correspondent clearing authorization removes the final structural barrier—institutions can now offer their clients blockchain-based securities and crypto assets through conventional brokerage accounts, subject to the same regulatory oversight and custody standards as traditional securities.
