What Is OpenReserve? a16z-Backed Blockchain Bank Wins OCC Preliminary Approval

For years, crypto companies have tried to make blockchains behave more like banks.

OpenReserve is attempting the opposite: build a regulated U.S. bank that behaves more like an always-on blockchain network.

On September 2, 2026, the U.S. Office of the Comptroller of the Currency granted preliminary conditional approval for the formation of OpenReserve Bank, National Association, in Salt Lake City, Utah. The decision appears in the OCC's official Interpretations & Decisions database.

OpenReserve describes the planned institution as a blockchain-native digital bank built around continuous capital markets, tokenized deposits, payments, lending, custody and on-chain settlement.

The company has also raised a $25 million seed round led by a16z crypto, adding venture backing to what is primarily a regulated-bank infrastructure story. a16z crypto's investment announcement confirms the investment and identifies OpenReserve founder Dee Choubey as the former MoneyLion executive behind the project.

The combination is unusual:

national bank charter + tokenized deposits + stablecoin infrastructure + on-chain capital markets.

If OpenReserve ultimately clears its remaining regulatory requirements and opens, it could become an important test of whether blockchain-native finance can be built from inside the U.S. banking system rather than alongside it.

Summary

OpenReserve Bank, N.A. received preliminary conditional approval from the OCC on September 2, 2026.

The bank is not yet open. OpenReserve says final OCC approval remains subject to pre-opening requirements, while additional approvals — including from the FDIC — are required before banking operations can begin. OpenReserve's official website explicitly identifies the entity as “in organization.”

OpenReserve plans to combine conventional banking services with blockchain-based infrastructure, including tokenized deposits, payments, custody, lending, tokenized securities and on-chain settlement.

The company is also developing ReserveUSD, or rUSD, a planned stablecoin designed for global capital markets and intended to comply with the U.S. GENIUS Act.

At the same time, OpenReserve proposes a tokenized-deposit model called rDEP, illustrating how the bank intends to support both stablecoins and commercial-bank money on programmable rails.

Its $25 million seed round is led by a16z crypto.

For the broader crypto industry, OpenReserve matters because it represents a different model of institutional adoption: rather than attaching blockchain products to a legacy bank after the fact, it is attempting to design the bank itself around continuous on-chain infrastructure.

What Is OpenReserve?

OpenReserve is a financial infrastructure company founded by Dee Choubey, who previously co-founded and led fintech platform MoneyLion.

Its central idea is what the company calls the “continuous bank.”

Traditional banking remains constrained by systems built around:

business hours;

batch processing;

multiple ledgers;

settlement windows;

correspondent banking;

and fragmented infrastructure.

OpenReserve wants banking, credit and capital markets to operate more continuously.

Its official description of the OpenReserve platform says the proposed bank is being designed to connect deposits, lending, payments, custody and settlement within a supervised institution while linking traditional finance to on-chain markets.

That does not mean every banking process suddenly becomes permissionless.

The more interesting idea is the opposite:

bring blockchain settlement inside a regulated banking perimeter.

Did OpenReserve Receive a U.S. Bank Charter?

It received an important regulatory milestone, but the wording matters.

The OCC granted preliminary conditional approval to establish OpenReserve Bank, National Association.

That is not the same as saying:

OpenReserve is now a fully operational national bank.

The OCC lists OpenReserve's application among its digital-asset licensing applications and shows that the national-bank application was received on April 13, 2026. The OCC's Digital Assets Licensing Applications database provides the official regulatory record.

OpenReserve itself states that it must still satisfy pre-opening conditions and obtain other necessary approvals, including FDIC approval, before beginning banking operations.

That distinction is important for both investors and readers following the development.

Why OpenReserve Is Different From a Crypto Bank

The phrase “crypto bank” is often used too loosely.

It can refer to:

a bank that serves crypto companies;

a custodian holding Bitcoin;

a fintech that offers stablecoins;

a company with a banking partner;

or a regulated institution using blockchain internally.

OpenReserve's proposed model is more ambitious.

Its planned infrastructure covers a spectrum including:

The important feature is integration.

OpenReserve is not presenting tokenized deposits as an isolated pilot.

It wants them to sit inside a larger banking and capital-markets architecture.

What Are OpenReserve Tokenized Deposits?

OpenReserve refers to its proposed tokenized-deposit product as rDEP.

A tokenized deposit is not the same thing as a stablecoin.

It represents commercial-bank money in programmable form.

If a business has $1 million deposited with a regulated bank, a tokenized-deposit system can potentially allow that bank liability to move over compatible digital infrastructure without transforming the money into an independently issued stablecoin.

MEXC recently examined this distinction in depth in Stablecoins vs Tokenized Deposits: Which Could Power the Future of Payments?. The key difference is the financial claim: a tokenized deposit remains connected to a commercial bank's balance sheet, while a stablecoin is typically a separately issued digital asset backed by reserves.

Why Would a Bank Put Deposits On-Chain?

Consider a conventional institutional payment.

Bank A sends money.

Bank B receives instructions.

Settlement infrastructure updates.

Internal ledgers reconcile.

Operations teams confirm balances.

Some processes remain dependent on operating windows and separate databases.

A programmable deposit could potentially compress parts of that workflow:

Bank deposit

↓

tokenized representation

↓

programmable transfer

↓

automated ownership update

↓

near-continuous settlement

The attraction is not simply speed.

Programmable money can potentially interact with other tokenized assets.

For example, a tokenized security and tokenized bank deposit could settle together in a delivery-versus-payment transaction.

That reduces the time during which one side of the transaction has moved while the other has not.

OpenReserve Is Also Planning a Stablecoin

OpenReserve is not choosing between tokenized deposits and stablecoins.

It is planning both.

The company's website describes ReserveUSD (rUSD) as a stablecoin built for global capital markets and designed with GENIUS Act compliance in mind.

This is strategically important.

Stablecoins and tokenized deposits solve related problems but serve different financial structures.

A possible future OpenReserve stack could therefore look like:

rDEP → regulated bank deposits

rUSD → transferable stablecoin liquidity

OpenReserve Bank → regulated balance sheet

Open Reserve Network → connectivity

tokenized securities → investable assets

That is much broader than issuing another dollar token.

MEXC Analyst View: The Important Innovation Is the Balance Sheet, Not the Blockchain

Priya Sharma, MEXC senior crypto industry analyst, sees OpenReserve as part of a wider shift in which the boundary between “crypto infrastructure” and “bank infrastructure” is becoming less useful. The interesting element is not that OpenReserve plans to use blockchain — many financial institutions already do. The more consequential question is whether a regulated bank can place deposits, credit and settlement on the same programmable financial architecture.

Sharma argues that this could change how the industry thinks about tokenization. Most tokenization projects begin with the asset: tokenize a Treasury, stock, fund or loan. But every transaction also requires a money leg. If the security moves instantly while the cash remains trapped in conventional settlement windows, much of the efficiency disappears. A bank capable of providing tokenized deposits alongside tokenized assets could address both sides of the transaction.

She also cautions against interpreting preliminary charter approval as proof that the model has already succeeded. Banking is ultimately a balance-sheet business involving liquidity, capital, credit risk, deposit stability and supervision. A blockchain can modernize how claims move, but it does not remove those constraints. OpenReserve's more important test will come after regulatory formation: whether institutions actually move meaningful deposits, financing and settlement activity onto its infrastructure.

Why the OCC Decision Matters

The regulatory context has changed substantially.

The OCC now maintains a dedicated public list of applications from entities planning digital-asset products and services. OpenReserve appears alongside a growing group of applicants seeking federal banking or trust structures for digital-asset activity.

That suggests U.S. crypto regulation is increasingly moving from abstract rulemaking toward institutional formation.

The industry is no longer asking only:

Can banks touch crypto?

It is increasingly asking:

What should a bank built for tokenized finance look like?

Why Tokenized Deposits Are Becoming a Major Banking Theme

Banks have a strong incentive to modernize deposits.

Stablecoins have already demonstrated that users value:

24/7 transfers;

programmability;

rapid blockchain settlement;

cross-border portability;

and integration with digital assets.

But stablecoins can move money outside conventional deposit structures.

Tokenized deposits allow banks to offer some of the same technical characteristics while keeping commercial-bank money within the banking system.

MEXC's earlier guide to what tokenized deposits are and why banks are developing them explains why they are emerging as one of the banking industry's main responses to blockchain-native money.

A Bank That “Never Closes” Does Not Mean Risk Never Exists

The “continuous bank” concept is attractive because capital markets increasingly operate globally.

But 24/7 infrastructure creates its own challenges.

A bank that moves money continuously needs:

real-time liquidity management;

continuous sanctions screening;

always-on cybersecurity;

resilient custody;

automated controls;

continuous fraud monitoring;

and operational systems capable of functioning outside conventional banking windows.

Those requirements can be more demanding than batch-based banking, not less.

Could OpenReserve Connect Stablecoins and Traditional Banking?

That may be one of the most important opportunities.

Stablecoins are highly portable on blockchain networks.

Bank deposits sit inside regulated balance sheets.

Institutional markets need both liquidity and legal certainty.

A platform that can move value between:

bank deposit → tokenized deposit → stablecoin → tokenized asset

could provide infrastructure bridging those systems.

The challenge is making those conversions legally clear, liquid and operationally reliable.

Why the Broker-Dealer Component Matters

OpenReserve's broader strategy also refers to combining banking with capital-markets infrastructure.

This matters because tokenized finance is not only about moving cash.

Institutions also need to issue, finance, trade, custody and settle assets.

A unified infrastructure could potentially support workflows such as:

tokenized fund issuance

↓

institution purchases asset

↓

tokenized deposit provides payment

↓

asset and cash settle programmatically

↓

collateral becomes available for financing

That is closer to re-engineering capital markets than simply creating a digital bank account.

Could OpenReserve Compete With Existing Banks?

Potentially, but its first competition may be infrastructure rather than retail banking.

OpenReserve says it is targeting institutional investors, corporate treasurers and financial-market participants.

That suggests the early opportunity is less about replacing a consumer checking account and more about improving how institutional capital moves.

Legacy banks have major advantages:

large deposit bases;

customer relationships;

regulatory experience;

capital;

global networks.

A new entrant's advantage is architectural.

It does not have to rebuild decades-old systems before introducing programmable infrastructure.

What Could Stop the Model From Working?

Several things.

Regulatory approval could take longer than expected.

Institutional clients may adopt slowly.

Tokenized deposits could remain fragmented between banks.

Stablecoins could dominate public blockchain settlement.

Legacy institutions could modernize faster.

Or the technical advantages of continuous settlement may not produce enough cost savings to justify migration.

There is also a basic network problem:

financial infrastructure becomes more valuable when many counterparties use it.

A technically excellent bank with limited counterparties still has limited utility.

What Should Investors and the Industry Watch Next?

The next milestones are more important than the preliminary approval itself.

Watch for:

final OCC authorization;

FDIC approval;

the formal opening of OpenReserve Bank;

details of deposit products;

ReserveUSD issuance;

the legal and technical structure of rDEP;

institutional customers;

supported blockchain networks;

and actual settlement volumes.

The strongest evidence will be usage, not architecture diagrams.

Why OpenReserve Could Matter Beyond One Bank

OpenReserve's biggest potential contribution may be demonstrating a model others copy.

If it proves that regulated banking can combine:

deposits;

stablecoins;

tokenization;

credit;

and continuous blockchain settlement,

existing banks may accelerate similar projects.

The competitive question would then change from:

Which banks support crypto?

to:

Which banks have the best programmable financial infrastructure?

That is a much larger transformation.
