Prometheum Capital launched Digital Brokerage Solutions on May 12, 2026, a suite of correspondent clearing, custody, and trading services enabling broker-dealers and RIAs to offer tokenized securities and crypto assets directly through traditional brokerage accounts. In connection with the launch, Prometheum cleared and settled what it described as the first ETH transaction executed directly inside a U.S. brokerage account, not through an ETF, ETP, or any wrapped structure. “It’s working with the underlying token. It’s a really big deal,” said Aaron Kaplan, founder and co-CEO of Prometheum Inc. The launch addresses what Kaplan calls crypto’s structural gap: tokenization has scaled, distribution has not. Without mainstream brokerage access, tokenized assets remain locked in specialist platforms outside the rails advisors actually use.
The Distribution Problem Nobody Solved
Tokenized securities—traditional assets like stocks, bonds, and funds issued as digital tokens on blockchain—have proliferated since 2023. Yet they’ve remained trapped in specialized custody platforms and alternative trading systems, inaccessible to retail investors using standard brokerage accounts. Kaplan frames the issue sharply: “Tokenization is a solution without a market.” Prometheum operates as an SEC-registered, FINRA-member broker-dealer, meaning it can legally bridge that gap. The company’s platform handles the full lifecycle: issuance, trading, custody, clearing, and settlement. It includes a transfer agent, alternative trading system (ATS), custody platform, and correspondent clearing capabilities. In May 2026, Prometheum joined the DTCC Industry Working Group alongside 50+ financial firms exploring tokenization infrastructure.
First Clearing Clients Signal Momentum
Arete Wealth Management, Network 1 Financial Securities, and an unnamed clearing broker-dealer are the inaugural correspondent clearing clients. Arete brings approximately $7 billion in assets under advisement across more than 60 offices and 260 registered reps, all of whom can now route tokenized securities and digital assets through Prometheum’s infrastructure into client brokerage accounts via a fully disclosed correspondent clearing agreement. “Adding digital and crypto assets through Prometheum Capital’s fully disclosed clearing means our advisors can manage clients’ investments and exposure to ETH and digital securities,” Arete Wealth CEO David Levine said. Crypto trading itself is delivered through Prometheum Capital’s integration with Talos, an institutional digital asset trading technology provider. Prometheum was licensed as a digital custodian in 2023 and received correspondent clearing authority in late 2025, the regulatory foundation that makes this launch possible.
Why This Matters for Blockchain Infrastructure
Tokenization advocates have long argued blockchain securities offer efficiency gains: faster settlement (T+0 vs. T+2), lower custody costs, and programmable financial logic. None of that value reaches mainstream investors without brokerage distribution. Prometheum’s integration with correspondent clearing—the operational backbone of how brokers execute trades—removes a major adoption bottleneck. Retail investors using Fidelity, Charles Schwab, or regional brokers will eventually access tokenized assets through familiar interfaces. This standardization could accelerate institutional adoption. The 3.7 million members of Stand With Crypto, a digital assets advocacy group, have contacted lawmakers 2.5 million times on regulatory clarity. Prometheum’s infrastructure demonstrates that clarity is now translating into operational products.
Next Milestone: The Institutional Test
The immediate question is adoption velocity. Will broker-dealers prioritize tokenized securities for retail clients, or will they treat them as niche products? Prometheum has signaled upcoming institutional distribution partnerships, though details have not been disclosed. Regulatory approval for Digital Brokerage Solutions itself has not been explicitly stated, though the company’s SEC-registered status and FINRA membership suggest compliance frameworks are in place. The next 12 months will show whether Wall Street views tokenization as infrastructure modernization or regulatory theater.
