The Awkward "Mutual Embrace": Banks Begin to Adopt Blockchain, but Ethereum Is Not in the Script

The "mainstream adoption" the crypto world has waited for years is finally here.

But perhaps not in the way many imagined.

According to CoinDesk reports [1][2], major U.S. banks like JPMorgan, Bank of America, and Citi plan to launch a shared tokenized deposit network through The Clearing House, expected to go live in the first half of 2027. In simple terms, banks want to turn deposits into digital tokens that can be transferred 24/7 within a blockchain network.

This sounds like mainstream finance is finally seriously going on-chain.

The awkward part is that their choice is not DeFi, not permissionless public blockchains, nor moving the financial system into the crypto-native world. Instead, it's a shared payment infrastructure owned by banks, a permissioned ledger, a consortium chain, and an institutional network where only transaction participants and authorized regulators can see the details.

Simultaneously, the DeFi world is experiencing a different kind of narrative pressure: ongoing security incidents continue to remind the market of the risks of on-chain finance, and the ETH and overall crypto markets are also clearly under pressure.

Thus, a sharper question arises:

If mainstream finance ultimately also uses blockchain, but chooses consortium chains and controlled settlement networks, how should the crypto world's narrative of "open, transparent, permissionless" over the past few years be reinterpreted?

This article does not evaluate ETH or any digital asset price performance, nor constitutes investment advice to buy, sell, or hold any digital asset. This article discusses market structure and technology adoption pathways.

1. The Crypto World Awaited Mainstream Adoption, But Got Consortium Chains

"Mainstream finance adoption" has always been one of the favorite stories in the crypto market.

In the early days, this story usually went like this:

Banks would be transformed by DeFi, Wall Street would connect to open public chains, traditional assets would be tokenized, and global finance would migrate to transparent, open, permissionless networks.

This vision was captivating.

Because it was not just a technical narrative but also a value narrative: old finance is closed, slow, expensive, opaque; new finance is open, fast, cheap, composable. Given enough time, the latter would replace the former.

But now, the answer from big banks is less romantic.

According to CoinDesk reports, JPMorgan, Bank of America, Citi, and other major U.S. banks plan to establish a shared tokenized deposit network operated by The Clearing House. The Clearing House itself is a payment company jointly owned by banks.

This means banks are not saying, "We want to join DeFi."

They are more like saying: We acknowledge the efficiency of blockchain, but we want to bring that efficiency back into the banking system; we acknowledge the value of on-chain settlement, but participants, permissions, data visibility, and liability boundaries must be controllable.

This is where the awkwardness lies: the crypto world got mainstream adoption, but mainstream finance brought not a victory declaration for open public chains, but a bank-controlled, regulated version of blockchain.

2. Why Consortium Chains? Because Banks Buy Certainty, Not Belief

Many crypto-native readers instinctively dislike consortium chains.

In the crypto context, consortium chains often imply "not open enough," "not decentralized enough," "not crypto enough."

But from a bank's perspective, the appeal of consortium chains lies precisely in these "not enoughs."

The questions banks and institutions need answered for settlement are not "Is this chain cool enough?" but:

• Who can join the network?

• Who can see transaction data?

• Who is responsible for KYC/AML?

• How do regulators obtain necessary information?

• Who is liable when something goes wrong?

• Will sensitive client and fund flows be publicly exposed?

Open public chains make many things public by default; banking operations keep many things confidential by default.

Open public chains emphasize permissionless; banking operations must know the identity of every participant.

Open public chains believe in code and market self-correction; banking operations need responsible entities, audit trails, and regulatory interfaces.

Therefore, banks choose consortium chains not because they don't understand DeFi, but because they understand they cannot operate like DeFi.

3. Under DeFi Security Pressure, Banks Are Even Less Likely to Embrace "Full Openness"

The DeFi world has not been quiet lately.

Public news reports that Radiant is moving towards shutdown after failing to recover from a 2024 hack [6][7]; meanwhile, recent crypto market volatility has seen significant pullbacks in assets like Bitcoin and Ether. Such events continuously remind the market that open on-chain finance still faces challenges in security, resilience, and institutional risk management.

These events do not mean DeFi lacks value, nor do they mean open public chains have failed.

But they change institutions' perception of risk.

For retail users, an exploit might be "the project's problem."

For a bank, an exploit involves issues for the board, legal, regulators, client compensation, and reputational risk.

These security incidents make some institutions more inclined to choose controllable, auditable, accountable permissioned rails. Banks don't reject on-chain efficiency; they don't want to expose their core payment and deposit systems to an environment they cannot explain, control, or hold accountable.

So, while DeFi is still proving it can be secure enough, banks naturally choose another path: use blockchain's efficiency, but retain the banking system's control.

4. ETH Under Pressure Makes the Question More Pointed: Does Mainstream Going On-Chain Truly Mean Victory for Public Chains?

Let's be clear on boundaries first: this article does not discuss ETH price, nor judge the investment value of ETH or any digital asset.

But against the backdrop of ETH and the overall crypto market clearly under pressure, the emotional tension of this question is stronger [7].

When markets are rising, all narratives easily seem correct: DeFi will expand, L2s will flourish, RWAs will enter public chains, institutions will come to the open ecosystem.

When markets fall, the questions become harsher:

If mainstream finance truly starts going on-chain, but chooses consortium chains;

If banks truly start creating tokenized deposits, but keep the cash leg within the banking network;

If Visa truly tests private stablecoin settlement, but on permissioned ledgers like Canton;

Then what portion of mainstream finance's benefits do open public chains actually capture?

The answer may not be "none."

Open public chains like Ethereum will still play a vital role in DeFi, stablecoin liquidity, open developer ecosystems, and crypto-native innovation.

But the answer is no longer "everything."

Mainstream finance going on-chain might not be a story of everyone migrating to the same open network, but one of parallel tracks: open public chains for open finance, bank consortium chains for institutional settlement, tokenized funds for yield-bearing cash management, stablecoins for global liquidity.

This is where belief is tested.

Not that open public chains have no future, but they might no longer hold all futures.

5. Stablecoins Have Forced Banks to Act on "On-Chain Deposits"

Why are banks acting now?

Because stablecoins have made the question very clear: Why can't dollars move 24/7, cross-border, with low friction?

In the crypto market, stablecoins have become the default cash instrument. Exchanges use them for quoting and settlement, DeFi uses them as collateral, market makers use them to transfer liquidity, cross-border payment companies test new channels with them.

CoinDesk cites a JPMorgan report stating [1][4] that while tokenized money market funds have yield advantages, they still only account for about 5% of the stablecoin universe; the report argues stablecoins maintain stronger circulation advantages in crypto trading, collateral management, settlement, cross-border payments, and liquidity management.

The truly powerful thing here is not the price stability of stablecoins, but that they have occupied the cash leg of the on-chain world.

Once the cash leg is occupied by stablecoins, trading, collateral, payments, clearing, and fund management will grow around it.

For banks, this is not a change they can afford to watch from the sidelines long-term.

Tokenized deposits are the banks' response: if users want the speed of on-chain dollars, can banks provide a version that doesn't leave the banking system?

6. Visa and Canton: Institutions Want On-Chain Efficiency, Not Public Scrutiny

Cointelegraph reports [3] that Visa is testing private stablecoin settlement with Brale and the Canton Network. Canton's feature is being a permissioned ledger: only transaction participants and authorized regulators can see specific transaction data, while supporting atomic settlement between tokenized assets, cash-like instruments, and financial contracts.

This news is on the same track as bank tokenized deposits.

Institutions don't reject blockchain.

What they want is:

• Faster settlement;

• Lower operational friction;

• Better fund scheduling;

• Programmable financial contracts;

• But also retaining privacy, permissions, auditability, and regulatory interfaces.

In other words, institutions want "on-chain efficiency," not necessarily "public scrutiny."

This statement might make crypto-native readers uncomfortable, but it is very close to the real needs of banks and payment networks.

7. The Next Phase of RWAs: Not Which Chain Assets Are On, But Who Controls the Cash Leg

When discussing RWAs in the past, the market liked to ask: What assets can go on-chain?

U.S. Treasuries, funds, private credit, real estate, stocks, bonds—all could be answers.

But this round of bank tokenized deposits changes the question:

Putting assets on-chain is only the first step; putting the cash leg on-chain is key to market structure.

Whether a tokenized bond is meaningful depends not just on whether the bond can be on-chain, but also on:

• What cash is used for settlement?

• Who is responsible for the redemption mechanism?

• Which investors can hold it?

• How are transfer restrictions enforced?

• How does secondary liquidity form?

• How are abnormal transactions handled?

A CoinDesk opinion piece compares tokenization to the market structure revolution of ETFs [5]. The value of ETFs is not "repackaging assets," but how creation/redemption, arbitrage mechanisms, continuous trading, and secondary liquidity collectively changed market structure.

For tokenization to truly become large, it also needs a similar market structure.

And the core of market structure has never been just the name of the chain, but cash, redemption, market making, permissions, and liability.

8. EX.IO Research Viewpoint: This Isn't a Technical Route Dispute, But a Trust Structure Dispute

EX.IO Research believes that the most noteworthy aspect of banks choosing consortium chains is not "consortium chains are back," but that it exposes the underlying divergence in blockchain adoption.

The crypto-native world believes: The more open, the more trustworthy.

Banks and institutional finance believe: The more controllable, the more trustworthy.

These two trust structures will not automatically merge just because both use blockchain.

Future tokenized finance will likely not be one path, but multiple:

• Open public chains hosting open finance, DeFi, global stablecoin liquidity, and developer innovation;

• Consortium chains and permissioned rails hosting bank deposits, corporate treasury, institutional settlement, and privacy-sensitive transactions;

• Tokenized funds / treasuries hosting yield-bearing cash management;

• Stablecoins continuing to serve as the cash leg for the crypto-native world.

So, mainstream finance adoption is not awkward.

The awkward part is that the crypto world thought mainstream finance would enter its script, but mainstream finance is writing another one.

Three Takeaways After Reading This Article

First, banks are not suddenly embracing crypto. What they are truly responding to is the challenge stablecoins pose to payment gateways, deposit relationships, and the on-chain cash standard.

Second, consortium chains are not simply a revival of an old concept. In institutional settlement scenarios, permissioned networks might be the very premise that makes banks willing to use blockchain.

Third, the key for RWAs will shift from "can assets go on-chain" to "how do the cash leg and trust structure form a closed loop." Without a settlement cash accepted by institutions, even the most beautifully tokenized asset is just packaging.
