Kinexys is J.P. Morgan's blockchain business. It operates a suite of financial infrastructure services for banks, corporations, and other institutions: moving money across a shared ledger, issuing and managing tokenized assets, and exchanging payment information between banks. Until late 2024, the same business ran under the name Onyx.

Kinexys is not a coin that can be bought on an exchange, and it is not a single public blockchain. It is best understood as a bank division with several products — some running on private infrastructure, others that now touch public networks.

Why Onyx Changed Its Name to Kinexys

J.P. Morgan announced the switch from Onyx to Kinexys on 6 November 2024. The rebrand also renamed the products underneath it, so older articles that mention Onyx or the JPM Coin System are describing parts of what is now Kinexys.

The name is new; the work is not. The bank's own timeline begins with a Blockchain Center of Excellence in 2015, the Interbank Information Network in 2017, JPM Coin in 2019, and the Onyx grouping plus a digital assets launch in 2020. Those milestones now carry today's names on the bank's history page, but the Kinexys brand itself dates from 2024.

The Core Kinexys Services

Most of what Kinexys does falls into three jobs: moving money, representing assets, and checking payment information.

How Kinexys Digital Payments and Blockchain Deposit Accounts Work

Digital Payments grew out of the original 2019 JPM Coin system. It gives J.P. Morgan clients Blockchain Deposit Accounts, which hold ordinary deposits but record and move them on the bank's own ledger.

The point is speed and control. A treasury team can initiate a payment, have it settle in near real time inside the network, and set treasury rules in code so that routine transfers run on their own. The bank lists API connections, SWIFT, and its own interfaces as ways to connect.

One operational detail matters. Transfers between accounts on the network run continuously, but money going to or from a traditional bank account still uses traditional rails, and the product page lists a Saturday downtime for those transfers. That seam is the detail to note when gauging what bank-run blockchain payments actually do: continuous settlement applies inside the network and ends where conventional banking begins.

A concrete example shows who this serves. On 14 April 2025, J.P. Morgan announced GBP Blockchain Deposit Accounts through its London branch, naming LSEG's SwapAgent and Trafigura as the first clients to open them. These are corporate and market-infrastructure accounts, not personal savings accounts.

JPM Coin: From Private Ledger to Base and Ethereum

JPM Coin is where most of the confusion starts, because the name has covered two different things.

• 2019: The original JPM Coin system launched as a private, permissioned way to move client deposits.
• 2024: That system was renamed Kinexys Digital Payments.
• 12 November 2025: J.P. Morgan made a USD deposit token — JPM Coin, with the ticker JPMD — available to institutional clients on Base, a public network, after a proof of concept.
• 19 October 2026: The bank announced that JPM Coin was also live on Ethereum.

That progression is the thread that makes sense of older coverage: pre-2024 material describes closed, permissioned infrastructure, while announcements from 2025 onward describe the same lineage operating on public networks.

J.P. Morgan describes today's JPM Coin as a bank-issued deposit token, not a stablecoin and not a cryptocurrency. Each token represents a deposit at the bank. Running on a public chain does not make it open to anyone; only counterparties the bank has vetted can hold and use it. That is the distinction the bank draws: the token is a bank deposit, and participation is limited to vetted counterparties. Compared with the stablecoins common on public networks, the difference is practical: each token mirrors a deposit held at the bank, and the eligible holders form a closed set, even though the underlying networks are open for anyone to inspect.

Kinexys Digital Assets and Tokenization

Kinexys Digital Assets is the bank's tokenization platform. It lets institutions create a digital version of an asset, transfer it, and handle its administration, while linking those on-chain records to the cash and settlement systems they already use.

Tokenization changes how an asset is recorded and moved. It does not change what the asset is worth, and it does not by itself make an asset easier to sell. The link to existing cash and settlement systems is what separates this from a token left isolated on-chain: the digital record is designed to plug into the infrastructure institutions already run.

Kinexys Liink and Confirm: Checking Payment Details First

Not every Kinexys product moves money. Liink is the information side of the business. Its Confirm service checks that an account exists, is active, and belongs to the named owner before a payment goes out, using a permissioned peer-to-peer exchange between participating banks. It addresses a plain failure mode in bank payments — account details that are outdated, mistyped, or no longer active — by running the check before funds move rather than after.

Who Can Use Kinexys

Kinexys is built for institutions. Access depends on the specific service, the country, and J.P. Morgan's own approval, and the bank's product pages do not guarantee the advertised benefits. There is no retail app and no token for individuals to buy.

One more name may appear alongside Kinexys: Partior. It is a separate company, founded in 2021 by J.P. Morgan, DBS, and Temasek after work on Project Ubin, and it builds cross-border payment technology. It is related through its founders, but it is not another name for Kinexys.

Because Kinexys is a set of products rather than a single network, the dependable way to follow changes — new currencies, networks, or services — is the bank's own announcements and product pages, the channels that documented the Base and Ethereum launches. For the official product list and current service details, see the Kinexys overview on J.P. Morgan's site.
