Crypto built the technology. But it forgot to build the on‑ramp for everyday investors.
That's the core argument from Aaron Kaplan, co‑founder and co‑CEO of Prometheum, a New York‑based digital asset infrastructure firm. "The story of tokenization so far has been about issuance, but no one has addressed the challenge of how to get those products to mainstream investors," Kaplan told CoinDesk. "Until tokenized and digitally‑native securities can reach investors through the broker‑dealer channels they already use, tokenization is a solution without a market."
It's a blunt diagnosis, and one that shapes everything Prometheum is now building.
What Prometheum Just Launched
Prometheum recently launched Prometheum Capital's Digital Brokerage Solutions, a suite of correspondent clearing, custody and trading services designed to let broker‑dealers offer crypto assets, including tokenized securities and other blockchain‑based financial products, directly through traditional brokerage accounts.
In simple terms: for the first time, a traditional broker‑dealer can offer clients digital assets without having to rebuild its entire infrastructure from scratch or touch a crypto exchange.
Prometheum's inaugural correspondent clearing clients include Arete Wealth Management, Network 1 Financial Securities, and an unnamed clearing broker‑dealer. More are expected to follow.
The "Special Sauce" Behind the Platform
Prometheum isn't a new name in regulated crypto. The company already operates a full network of SEC‑registered and FINRA‑member entities.
It operates a network of regulated entities spanning the digital asset lifecycle, including a transfer agent, broker‑dealer, alternative trading system, custody platform and correspondent clearing infrastructure. Kaplan described the firm's clearing‑enabled custodian as its "special sauce."
That full‑stack regulated approach is what separates Prometheum from most crypto infrastructure players, and it's what makes the broker‑dealer pitch credible.
The Flywheel Effect
Kaplan describes Prometheum's platform as a two‑sided engine. The company says its platform serves two primary functions: helping issuers distribute tokenized securities into the broader financial system, and enabling traditional broker‑dealers to build digital asset businesses without relying on crypto‑native exchanges. That creates what Kaplan calls a "flywheel effect," connecting issuers with institutional distribution channels while giving traditional financial firms access to the growing market for blockchain‑based assets.
Why the Broker‑Dealer Channel Matters So Much
"The broker‑dealer channel is how you reach investors at scale," Kaplan said. "Now, for the first time, broker‑dealers and RIAs can offer digital assets directly through their existing account structures and compete with crypto trading venues on a more level playing field."
This isn't just about convenience. It's about trust. Most retail investors are far more comfortable buying assets through their existing brokerage account than signing up to a crypto exchange, and that comfort gap has kept billions of dollars on the sideline.
The Future Is Onchain, But Needs Wall Street to Get There
Prometheum joined the DTCC Industry Working Group in May as one of more than 50 financial firms helping shape the development of the Depository Trust Company's tokenization service.
"The future of securities is onchain," Kaplan said. "Integrating blockchain into capital markets isn't about replacing the system, it's about modernising it so that issuers, broker‑dealers and investors all benefit from faster settlement, broader access and more efficient distribution."
Prometheum's bet is clear: crypto built the rails, but Wall Street holds the keys to mass adoption. Without traditional distribution, tokenized securities remain a technology looking for a market. With it, the entire landscape changes.
