Of course, these decisions are not a sign that nobody wants this. Considered alongside the rest of the year, it is the opposite. Binance made a protocol-level ask in 2024 and had a ZIP within the year. Gemini has run shielded withdrawals under regulatory supervision since 2020. The ecosystem stood up a Washington policy organization in June and an institutional-integration shop in August. What the committee said, in effect, is that the need has not yet been written down as a requirement anyone can build to.

A viewing key is in this sense retroactive. It decrypts the account's entire history from the moment the account was created, and it cannot be withdrawn once shared, short of moving funds to a new account. There is no per-transaction viewing key and no time-bounded one. Josh Swihart, chief executive of ZODL, the company formed this year by the protocol's former ECC engineering team, confirmed this, also mentioning that per-transaction payment disclosure is "not implemented anywhere."

So what ships today is account-scoped viewing keys, full or incoming-only, retroactive, irrevocable and shared at the account holder's initiative, with transaction-level disclosure on the roadmap.
Disclosure mechanisms, in Zcash or anywhere else, can be located on the following: What is revealed (scope). To whom (grantee). When the grant takes effect and how far back it reaches (timing). Whether it can be withdrawn (revocability). And who initiates it, the data subject or an authority (initiation).

SD-JWT (Ɔwɔ sε wɔsan bɔ no), ISO mdoc and BBS+ signatures are built to do. The unit of disclosure is an attribute, the moment is presentation time, and the holder decides per interaction.
In the shielded-payments world the phrase means revealing transaction data to a chosen party, where the unit is an account's history and the moment is whenever the key is handed over.

ZIP 320, transparent-source-only addresses, and the ZIP text indeed records the origin "as required by Binance." A TEX address is an ephemeral transparent pass-through that guarantees the exchange receives funds from a transparent source. It gives the exchange a return path without giving it the sender's history. The one accommodation the protocol made to an exchange discloses exactly what the exchange asked for and nothing more.

Divij Pandya is working the other end of that conversation. He is executive director of Pretty Good Policy for Zcash, the Washington policy organization stood up in June as a continuation of an earlier ECC-led initiative, and his organization's project is to get viewing-key disclosure recognized as an acceptable compliance mechanism in a document a compliance officer can cite. To his knowledge, he said, no regulator has yet engaged with viewing keys as an instrument. PGPZ's scope, naturally, is recognition rather than builder guidance. A tool cannot be specified against a requirement until someone with authority has ruled on the instrument, so recognition is the upstream step. The organization's filings are signed by Paul Brigner as PGPZ's founder and as ZODL's chief policy and regulatory officer, so the policy and engineering efforts share an officer as well as a thesis.

Any disclosure design that attaches a reference to a transaction proves only the last hop, and the last hop could be the depositor themselves. A viewing key has the same limit. It reveals the account holder's transactions, not where the counterparties' funds came from, which is the question a sanctions screen asks.

Ɔpɛnimaa 2020, when a spokesperson credited ongoing conversations with regulators, extended that to the Orchard pool in November 2025, and to the post-Ironwood pool two days after activation in July 2026. It accepts deposits sent from shielded addresses into transparent custody. Kraken's kɔ a wɔtwe no ho address list supports transparent ZEC addresses only, Coinbase is likewise transparent-only, and Binance requires TEX. What no major regulated exchange yet offers is shielded custody, a shielded deposit address, or a workflow into which a customer's viewing key would go.

None is an exchange workflow, and none has a regulator's attention. Each is the accountant-facing half of the same problem, built by one or two people without a partner asking, and ZecBooks' scoped export is selective disclosure operating at the interface where it is most often needed first: between a shielded user and the person keeping their books.

If memo bundles land in the upgrade after NU7 and the reply-address draft follows, "targeted transaction information" in PGPZ's filings becomes literal. That is at least two upgrades away, and the regulatory answer arrives on a regulator's timeline.
