The next phase of digital finance will be built inside the platforms where people already spend their time and money, and the shift is redefining what it means to be a financial company.

For most of the past decade, “institutional adoption” in crypto carried a fairly narrow meaning: a bank offering custody, an asset manager launching a fund, or a financial institution running a tokenization pilot. The prevailing assumption was that crypto would succeed by finding its way into the institutions that already existed.

That process is underway. But the more consequential development may be finance moving in the opposite direction—out of traditional financial institutions and into the products where people already work, sell, create, communicate and spend. Commerce platforms now offer working capital, software companies process payments, marketplaces issue cards, and consumer platforms increasingly want accounts, savings, trading and cross-border money movement embedded directly into their products. The approach is known as embedded finance: financial services delivered inside the products of companies whose core business lies elsewhere.

The economics are already pushing companies in that direction. J.P. Morgan's 2026 fintech outlook cites a roughly $185 billion addressable embedded-finance market across the United States, Canada and Europe, and reports that 91% of SaaS companies expect embedded payments to play a larger role in their growth strategy this year. Companies that already own distribution are discovering that financial services can deepen the customer relationship rather than sending that customer elsewhere.

At the same time, the rails underneath finance are changing. A 2026 Coinbase and EY-Parthenon survey of institutional investors found that 85% use, or are interested in using, stablecoins for internal cash management and money movement, while 64% of asset managers expressed interest in tokenizing assets. Nasdaq's $100 million investment in Kraken's parent company, alongside a deeper partnership around tokenized equities, is another indication that the boundary between traditional market infrastructure and onchain finance is becoming less meaningful.

Combining the two trends points to a far larger market. Companies with millions of customers now have both the incentive to offer financial products and access to infrastructure that can operate globally, programmatically and around the clock. The constraint is increasingly the difficulty of building it.

A company seeking to serve users across markets can quickly find itself integrating custody, identity, compliance, banking relationships, fiat settlement, liquidity, transaction routing and multiple blockchain networks. Each additional vendor creates another integration and another point where the product can break. What begins as a promising new revenue line can turn into a multi-year infrastructure project before the first customer ever uses it.

This is why self-custody matters far beyond crypto wallets. The industry has traditionally treated self-custody as a philosophical choice for individual asset holders—own your keys, control your assets. Its bigger opportunity is architectural.

A self-custodial financial stack can separate ownership from orchestration. The user retains control of assets while infrastructure handles the routing, identity, compliance, settlement and connectivity required to make those assets useful. Done properly, the customer does not need to understand blockchains, bridges or liquidity venues any more than someone making an international card payment needs to understand correspondent banking.

That distinction matters enormously for the next generation of financial companies, because many of them will not begin as financial companies at all. They may start with millions of musicians, merchants, gamers, creators or businesses already using their products. Their advantage lies in distribution, trust and knowledge of their customers—not expertise in custody architecture or blockchain settlement.

The logical end state is infrastructure that allows those companies to add financial capabilities without rebuilding the financial system beneath them. A music platform should be able to give an artist better ways to receive, hold and move money A global marketplace should be able to offer sellers accounts, payments or credit. A software company should be able to make financial services part of its product without becoming a bank or assembling a different technical stack for every country and network it enters.

A second-order effect may prove just as important. When multiple products operate on shared infrastructure, the underlying system improves with scale: more volume generates better routing information, broader network connectivity creates more possible transaction paths, and common identity and compliance infrastructure reduces duplicated work. Instead of every new financial product beginning at zero, each can inherit infrastructure strengthened by what came before it.

These themes form part of the argument the author is set to make at Korea Blockchain Week, in a discussion of the self-custodial banking stack that institutions can build on.

Crypto has spent years asking how to get institutions onchain. The bigger question now is what happens when onchain infrastructure becomes good enough that millions of companies can build products on top of it. That is a far larger opportunity than putting existing financial products onto new rails—it changes who gets to build financial products in the first place. The next major financial institution may not look like a bank at all. It may already have millions of customers and simply be waiting for the infrastructure to catch up.
