The hybrid era of the future of finance

There's a story that crypto tells itself, and it goes something like this: open, permissionless systems will replace closed, regulated ones. The banks will fall. The protocols will rise. The future is decentralized all the way down.

There's another story that TradFi tells itself: blockchain is interesting technology, and we'll adopt it. On our terms, inside our walls, with our rules. That means permissioned chains, institutional custody, and compliance-first everything.

This week, both stories broke.

What actually happened is more interesting than either camp predicted. Three of the most powerful financial institutions on earth (BlackRock, Société Générale, and Nasdaq) each independently chose to deploy regulated value directly onto public, permissionless blockchains. Not private chains, or high-tech-sounding walled gardens, but actual open infrastructure.

And at the same time, one of DeFi's most active infrastructure protocols, Across, a cross-chain bridge, proposed dissolving its DAO and becoming a US C-corporation. In this case, a DeFi protocol is proposing that converting its governance in a closed structure so its open infrastructure could scale.

If you look at these four moves together, they describe a third path that both the crypto maximalists and the TradFi incumbents never fully anticipated. And understanding this path is, I think, the most important strategic insight for anyone building, investing in, or writing about digital assets right now.

The thesis: Open financial infrastructure is shifting to hybrid models that let regulated issuers plug closed value into composable, programmable public rails.

What happened this week (and what it means)

We'll start with BlackRock, because the scale matters. BUIDL, their tokenized US Treasury fund, crossed $2 billion in AUM and is now functioning as native collateral inside Morpho lending vaults on Base.

What that actually means: A US Treasury product, issued by the world's largest asset manager, is earning DeFi yield inside a permissionless lending protocol on a Layer 2 network. No one asked BlackRock's permission to use BUIDL this way. The asset is composable. It plugged into the open intermediation layer because the intermediation layer was designed to accept any asset that meets its smart contract interface.

This is $2 billion of the safest collateral in the world sitting inside open financial infrastructure because it's more capital-efficient there than anywhere else.

Now look at SocGen. Société Générale-FORGE deployed EURCV, a fully MiCA-compliant euro stablecoin, on Stellar's public blockchain. The decision to use a public, permissionless ledger rather than a private chain is the important part.

SocGen is a bank with 160,000 employees and $1.7 trillion in assets. They have the resources to build their own private infrastructure. But instead they chose open rails because open rails provide global composability that private rails cannot match.

An EURCV holder can now interact with any application on Stellar without SocGen's involvement. The settlement layer just became multi-currency and institutional, on public infrastructure.

Nasdaq's announcement is further out (2027) but the architecture decisions being made now will define how equity markets work for the next generation. They're building tokenized equities with onchain programmable shareholder rights.

Corporate actions executed via smart contract. Proxy voting that's transparently verifiable, which ultimately leads to the rules of corporate governance encoded as auditable, executable code instead of locked in closed registrar databases.

And then Across: The cross-chain bridge protocol that has moved billions across L1s and L2s proposed converting from a DAO to a C-corporation. The governance becomes closed, or at least closed in the traditional legal sense, so that the protocol can sign institutional contracts, manage regulatory relationships, and access traditional capital markets.

The pattern: Open rails and adaptive governance

Here's what all four examples have in common: the technology layer remains open, permissionless, and composable. The governance and compliance layer adapts to the regulatory environment it needs to operate in.

Open rails, adaptive access

BlackRock's BUIDL lives on a public L2, but the fund itself is a regulated product with KYC requirements for direct holders. The composability is permissionless (anyone can build on top of it) but the initial issuance is gated.

Open settlement, adaptive compliance

SocGen's EURCV settles on a public chain but its also MiCA-compliant. The settlement is permissionless (anyone can receive and transfer EURCV) but the issuance adheres to European regulation.

Open verification, adaptive coordination

Nasdaq's tokenized equities will execute governance onchain, but the securities themselves are regulated instruments. The programmable logic is open (anyone can audit the smart contract) but the securities law framework is closed.

Open infrastructure, adaptive organization

Across keeps its bridge protocol permissionless, but wraps its organizational governance in corporate structure. The infrastructure remains open. The decision-making adapts.

Why hybrid models are the new architecture

The case for hybridity rests on a simple observation: the five dimensions of openness I track in the Open Money framework don't need to be fully maxed out on every dimension to be transformative. They just need to be more open than the system they're replacing.

Consider BUIDL as collateral in Morpho. On the permissionless access dimension, it's partially open. Anyone can use BUIDL as collateral in DeFi, but not everyone can mint new BUIDL tokens directly from BlackRock. On transparent verification, it's fully open. The onchain supply, vault positions, and liquidation parameters are all auditable. On programmable logic, it's fully open. Smart contracts auto-execute lending, borrowing, and liquidation. On composable infrastructure, it's fully open. Any protocol on Base can integrate BUIDL without BlackRock's involvement. On sovereign custody, it's partially open. Users hold BUIDL in self-custodied wallets, but the underlying Treasuries are custodied by traditional institutions.

Score that against traditional Treasury access: closed on every dimension. You need a brokerage account. You can't verify the custodian's solvency in real time. You can't programmatically use Treasuries as collateral across multiple platforms simultaneously. You can't compose Treasury exposure with other financial products permissionlessly. You don't hold the instruments yourself.

The hybrid model scores dramatically higher on openness across every dimension, even though it's not maximally open on any single one, and that's enough to be transformative.

The hard question: Does hybridity preserve openness or erode It?

This is where the tension in this thesis exists.

When Across converts from a DAO to a C-corp, something real is lost. Token-holder governance (messy, slow, sometimes dysfunctional) is replaced by a board of directors. The technology remains permissionless, but the strategic decisions about that technology are now made in a closed room. If the board decides to restrict bridge access to certain chains, or prioritize institutional clients over retail users, the open infrastructure serves closed interests.

When BlackRock's BUIDL enters DeFi with compliance wrappers (soulbound tokens, dynamic transfer restrictions, and newer token standards designed for easier integration with regulated assets, like ERC-7518) those wrappers travel with the asset. The composability is real, but it's composability with conditions attached. If those conditions become restrictive enough, the "open" stack becomes a regulated stack that happens to use blockchain as a database.

When Nasdaq builds programmable shareholder rights, the programming is open and auditable. But the rules being programmed are securities regulations. Open infrastructure executing closed-system logic is still a meaningful improvement in transparency and efficiency, but it's not the same thing as open governance.

The honest assessment: hybrid models increase net openness on the dimensions that matter most for efficiency and composability (transparent verification, programmable logic, composable infrastructure) while potentially limiting openness on the dimensions that matter most for sovereignty and access (permissionless access, sovereign custody).

Whether that tradeoff is acceptable depends on what you think open money is for.

How the hybrid model unfolds

I think the hybrid era unfolds in three phases.

Phase 1 (now through 2027): Institutional adoption. Regulated value migrates to public rails because the rails are better infrastructure. BlackRock, SocGen, and Nasdaq are the early movers, but they won't be the last. Every major custodian, exchange, and asset manager is running the same analysis. The settlement layer absorbs regulated fiat. The intermediation layer absorbs regulated assets. The coordination layer absorbs regulated governance logic.

Phase 2 (2027-2029): The composability explosion. Once a critical mass of regulated assets live on open rails, the second-order effects begin. Tokenized Treasuries as collateral for stablecoin lending as settlement for tokenized equities. All composable, all programmable, all operating 24/7 without intermediaries. The full stack becomes greater than the sum of its parts, and the value of being on open rails becomes self-reinforcing.

Phase 3 (2029+): The governance reckoning. As open infrastructure becomes systemically important, the question of who governs it becomes unavoidable. Does the coordination layer evolve toward decentralized governance models that can handle institutional-scale decision-making? Or do corporate structures like Across's C-corp become the default?

The bottom line

The future of finance is not fully open, but it also can't be fully closed. It's a hybrid architecture where open, permissionless, composable infrastructure serves as the base layer (the settlement rails, the lending protocols, the programmable logic) while governance and compliance adapt to whatever regulatory environment the system needs to operate in.

The Open Money thesis has always been that money is becoming infrastructure. Open, programmable, composable infrastructure that anyone can build on. This week showed that the path to getting there runs through the hybrid era: The rails are open, the value flowing through them is increasingly regulated, and the governance models connecting the two are still being written.
