On June 2, 2026, the U.S. Patent and Trademark Office issued PayPal, Inc. a patent, US12646047B2, titled “Methods and systems for transferring unspent transaction output (UTXO) tokens in a blockchain network.” The claim covers a narrow but concrete problem in on-chain token mechanics: how to move a large number of UTXO-model tokens at once without paying the per-token computational and network cost of transferring each one individually. For a company that has spent two decades patenting the plumbing of digital payments, the grant is a marker of where some of that plumbing now runs — across a public blockchain rather than only PayPal's own rails.

The disclosed method works by indirection. Rather than send each token to a recipient one by one, the system generates a delegated account, moves the UTXO tokens into it, and then transfers ownership of that delegated account in a single transaction. The abstract states the cost rationale directly:

The ownership of the delegated account can then be transferred to another use of the blockchain network in a single transaction, thereby avoiding the need to individually transfer the UTXO tokens and incur the memory and computational resource burden and costs associated with therewith.— Methods and systems for transferring unspent transaction output (UTXO) tokens in a blockchain network, US12646047B2

The grant notes the approach is meant for blockchain schemes “with lineage tracking mechanisms (e.g. as may allow for clawback of tokens)” — that is, token systems where each unit's history must be preserved, which is exactly the case for regulated or asset-backed tokens that an issuer may need to recall. The classifications track the substance: the record carries CPC G06Q 20/3672 (cryptographic mechanisms applied to payment), G06Q 20/0658 and G06Q 20/3678 (e-cash and digital-currency transaction handling), and H04L 9/50, the blockchain-specific cryptography subclass. This is a payments patent that happens to be written for an on-chain settlement environment.

A payments estate reaching into crypto rails

PayPal's overall grant footprint is vast and overwhelmingly classical-payments — its issued records cluster in classes such as G06Q 20/3224 (payment via mobile device), G06Q 20/4016 (transaction fraud detection), and G06Q 20/40 (authorization). The UTXO grant sits at the crypto-adjacent edge of that estate, and it is not alone there. Issued the same day, US12647776B2 covers on-device data-privacy operations that abstract user data at merchant locations — a privacy-of-transaction claim adjacent to how wallets disclose information. And on June 16, 2026, the office issued US12657557B2, a “carbon neutral blockchain protocol for resolving carbon offsetter payments for cryptocurrency transactions,” whose claims describe a “green wallet” that signs a cryptocurrency transaction and routes an offset fee to a carbon offsetter over a separate cryptocurrency processing network.

Read together, these grants describe a company extending established payment competencies — fee settlement, fraud and authorization, privacy of transaction data — into a cryptocurrency context. The UTXO transfer grant addresses transaction cost; the green-protocol grant addresses fee routing and settlement; the on-device privacy grant addresses what a wallet reveals. The named inventors on the UTXO and green-protocol grants overlap — Charles Gabriel Neale Dalton appears on both US12646047B2 and US12657557B2 — which indicates a common engineering group inside the company working the on-chain-payments problem.

Where the issued claims sit in the week's activity

In the U.S. blockchain grant window of June 2 to June 8, 2026, the records indexed for the sector keyword set number 42 issued patents, spread across a long list of single-grant assignees — financial names appear, but no one company dominates the week. PayPal is one of the recognizable payment incumbents in that drop, alongside grants to Citibank (US12645805B1), covering generation and testing of on-chain programs, and Precidian Investments (US12646040B2), covering asset-backed digital tokens generated inside a trusted execution environment. The presence of these names in the same week is a factual indicator that established financial and asset-management firms — not only crypto-native startups — are accumulating issued claims at the token-mechanics layer.

The classification pattern in that week reinforces the point. Of the 42 grants in the window, the most common CPC class was H04L 9/50 — the blockchain-specific cryptography subclass — appearing on 16 of them, followed by H04L 9/3247 (signature-with-verification protocols) on 10 and H04L 9/3236 (hash-based protocols) on six. PayPal's UTXO grant carries H04L 9/50 and pairs it with the payment-cryptography classes G06Q 20/3672, G06Q 20/0658, and G06Q 20/3678. That places the grant at the overlap of two clusters: the cryptographic-mechanism classes that dominate the week's blockchain drop, and the payment-handling classes that dominate PayPal's own estate. A grant sitting at that intersection is, factually, a payments company writing claims in the vocabulary of on-chain settlement — which is the substance of the directional read, stated through the classification data rather than asserted. The records do not establish how often the technique is used or whether it confers any advantage; they establish only where the company sought and obtained coverage.

What the PayPal grant establishes is specific and bounded: an enforceable claim to a cost-reduction technique for bulk UTXO transfer, including for clawback-capable tokens, owned by one of the largest payment processors in the world. The record says nothing about whether PayPal ships this in any product, how many on-chain transactions it processes, or how the claim compares in scope to any rival's. Those questions the patent does not answer. What it does map is the area where PayPal has now sought and obtained coverage — the intersection of high-volume payment processing and on-chain token settlement — and the small but growing cluster of crypto-context grants accreting at the edge of its very large classical-payments estate.
