DTCC’s clearing subsidiary DTC now has SEC staff approval to tokenize blue-chip U.S. securities on public and private blockchains, and JPMorgan just put a tokenized cash leg on Ethereum. Buried in the details sits a feature crypto natives will fixate on: a built-in “undo button” that lets DTCC reverse on-chain movements when it decides something went wrong.
The SEC’s Division of Trading and Markets granted DTC a three-year no-action letter on December 11, 2025 to launch “DTCC Tokenization Services” for Russell 1000 equities, major index ETFs, and U.S. Treasuries, with rollout targeted for the second half of 2026. The relief lets DTC represent existing securities entitlements as tokens on pre-approved L1s and L2s while keeping its own books as the legal record of ownership.[SEC no-action letter][DTCC release]
Four days later, on December 15, J.P. Morgan Asset Management launched the My OnChain Net Yield Fund (MONY), a 506(c) tokenized money market fund that lives on public Ethereum, seeded with $100 million and restricted to qualified investors using the bank’s Morgan Money platform.[JPMorgan press release] Fund shares arrive as tokens at client Ethereum addresses, with subscriptions and redemptions in cash or stablecoins and assets parked entirely in U.S. Treasuries and Treasury-backed repos.
ETH traded around $3,055 on Monday, up roughly 2.3% over 24 hours as tracked by CoinGecko, while traders parsed what this combination of DTC entitlements and JPMorgan cash tokens means for real settlement on public chains.[CoinGecko]
What DTCC actually put on-chain
The tokenization pilot does not create native blockchain securities. It creates “Tokenized Security Entitlements” that mirror positions already held at DTC in a new digital format.
According to the SEC letter, a DTC participant can instruct DTC to move eligible securities from its regular account into a “Digital Omnibus Account” and mint tokens representing that entitlement to a Registered Wallet on an approved blockchain. DTC’s LedgerScan system watches those chains, records token balances by wallet, and serves as the official book of record for the tokenized entitlements.[SEC no-action letter][Sidley analysis]
On-chain transfers between Registered Wallets can happen 24/7 without DTC in the transaction path, but DTC still tracks every move and can detokenize back into its traditional ledger when a participant asks. Critically for risk, DTC told the SEC it will assign zero collateral and settlement value to these tokenized entitlements inside its own clearing risk models. That keeps them outside DTC’s margin and default waterfalls for now.[SEC no-action letter]
How the on-chain “undo button” works
The sharp break from crypto norms comes in a section the SEC letter and law firm summaries label “Conditions Requiring Reversal.” DTC insisted that every supported blockchain and token standard must allow it to unwind transfers when tokens are lost, mis-directed, or involved in misconduct.[SEC no-action letter][Sidley analysis]
Will transfers on-chain be irreversible? No.
That blunt line comes from Sidley Austin’s summary of the no-action relief and captures the core design choice.[Sidley analysis]
Under the framework DTC described, supported token contracts must be “compliance-aware.” Tokens can move only between wallets DTC has registered, and DTC operates a “root wallet” on each chain. With that root, DTC can mint, burn, or move any token even without the private key of the wallet that currently holds it. DTC told regulators it will keep those root keys in cold storage except where daily operations require otherwise.[Sidley analysis]
In practice, that setup means on-chain state is not final for these entitlements until DTC accepts it. If DTC flags a “Condition Requiring Reversal” such as an erroneous entry, lost tokens, or malfeasance, it can use the root wallet to claw tokens back or reassign them and then adjust LedgerScan’s off-chain record accordingly.[SEC no-action letter]
For crypto users used to block explorers as ground truth, that is a sharp philosophical break. The chain still broadcasts transfers. The legal entitlement can move back in time if DTC decides the move should not stand.
On-chain, but not permissionless
The same controls that enable reversals also fence these tokens off from open DeFi. DTC will publish a list of public and private ledgers it considers acceptable. Participants must register specific wallet addresses as “Registered Wallets,” and the token standards must prevent transfers to any other address.[SEC no-action letter][DTCC tokenization overview]
Sidley’s note makes clear that blockchain records are not the official ownership record. LedgerScan’s off-chain books control the entitlements. On-chain movements simply instruct LedgerScan how to update balances, subject to the possibility that DTC uses the root wallet to step in and override them.[Sidley analysis]
That structure trades away composability in exchange for control. A tokenized S&P 500 ETF sitting in a DTC-registered wallet will not plug into an unpermissioned lending pool or DEX, because the protocol’s contracts will not be on the allowlist. From a bank and regulator perspective, that is the feature. From a DeFi perspective, it limits how far these assets can bleed into the rest of Ethereum’s contract surface.
JPMorgan’s MONY puts cash on Ethereum rails
JPMorgan’s MONY fund supplies the other half of the settlement equation: tokenized cash-like instruments on the same chain DTCC expects to support. The fund invests solely in U.S. Treasuries and repo backed by Treasuries and issues an ERC-style token at Ethereum address 0x6a7c6aa2b8b8a6A891dE552bDEFFa87c3F53bD46 to qualified investors’ wallets.[JPMorgan press release]
JPMorgan positions MONY as a way for treasury desks to keep idle balances in a yield-bearing, on-chain format, with daily dividend reinvestment and subscriptions or redemptions in either fiat or stablecoins through Morgan Money. Transfers are peer-to-peer within the product’s own compliance rules, giving large clients a venue to move tokenized cash around collateral workflows without touching retail-facing stablecoins.[JPMorgan press release]
CryptoSlate first framed the combination of DTCC’s entitlements and JPMorgan’s on-chain fund as the moment “cash meets settlement” for Wall Street on-chain. The article highlighted that, taken together, they sketch a path where regulated cash tokens can meet regulated tokenized securities on public infrastructure without abandoning legacy controls.[CryptoSlate]
Why the “undo button” matters for crypto rails
Institutional tokenization already exists in the form of Franklin Templeton’s BENJI fund on Stellar and Polygon and BlackRock’s BUIDL fund, which recently crossed roughly $2.5 billion in assets and now sits on multiple chains including Ethereum, Avalanche, Polygon, Aptos, and BNB Chain.[Franklin Templeton][BlackRock / Yahoo Finance][CoinDesk on BUIDL]
DTCC’s pilot shifts the center of gravity. Instead of an asset manager tokenizing its own fund shares, the U.S. central securities depository will sit between issuers and the chain as a tokenization hub for mainstream stocks, ETFs, and Treasuries. The SEC’s no-action letter even exempts DTC from core clearing-agency rules for this pilot, which law firms describe as an unprecedented regulatory edge over would-be competitors.[Sidley analysis]
For crypto markets, the friction point is clear. To fit inside this framework, public chains must accept issuer-level admin keys that can rewrite balances, and assets must live behind allowlists that keep DeFi at arm’s length. That approach echoes centralized stablecoins that maintain blacklist controls, but here the issuer is the core settlement utility for U.S. securities and the override is a formal regulatory requirement rather than a side feature.
The result is a new class of tokens that live on Ethereum and other chains, reference trillions of dollars in traditional assets over time, and yet move inside a tightly controlled perimeter where an “undo button” sits in the hands of the same entity that already runs Wall Street’s back office. For traders who grew up on “code is law,” this is not a side issue. It is the price institutional capital is demanding to take blockchain settlement seriously.
