The Zcash Foundation has publicly disowned two products — the ZRC-20 token standard and its first token, CASH — after an announcement for them was published through the Foundation’s own X account, leaving investors to wonder how promotional material for an unofficial project appeared on an official channel.

The Hook: “Zcash Now Has a Token Standard” — Except It Doesn’t
On Sept. 21, a post published through the Zcash Foundation’s X account announced, “Zcash now has a token standard.” It said ZRC-20 would soon let users deploy, mint, and transfer tokens on the privacy-focused blockchain, with CASH presented as the first token using the system, and directed users to the project’s website.
Then came the reversal. In a follow-up statement, the Foundation said it had no prior knowledge of either product, identified ZRC-20 as a privately developed third-party system, and urged users to do their own research before interacting with it. Both products, the organization stressed, are not official parts of the Zcash protocol and have no connection to the nonprofit.
No public explanation has established how the promotional post appeared through the Foundation’s account in the first place. Without confirmation from the organization, the incident cannot officially be called a hack or an account compromise — but the confusion itself is the story for anyone holding ZEC.
On-Chain Evidence: What ZRC-20 Actually Is
According to the project’s own technical documentation, ZRC-20 is a draft specification that stores token instructions as JSON data inside encrypted memo fields attached to shielded Zcash outputs — a 512-byte note that rides along with private transactions. Independent indexers would read those instructions in block order and calculate balances outside the Zcash consensus system.
If that sounds familiar, it should: ZRC-20 borrows its structure from Bitcoin’s BRC-20 format, which records token instructions through inscriptions. The key differences:
- Not a consensus change — Zcash nodes would neither validate nor reject ZRC-20 token instructions
- No smart contracts — balances live in third-party indexers, not on the blockchain itself
- Three operations only — deploy, mint, and transfer, with balances recognized only by software following the indexer’s rules
The privacy angle is murkier than it appears, too. The documentation notes that one proposed design sends operations to a common protocol address and publishes its incoming viewing key so indexers can decrypt the token instructions — meaning token activity would be readable by the indexer even though other parts of the transaction remain shielded. Ownership would rely on Ed25519 signatures embedded in each payload. Several features, including atomic trading, remain unresolved open questions.
The Core Conflict: Third-Party Tokens on Someone Else’s Chain
The Foundation’s central point is a distinction many investors miss: anyone can build an application that uses Zcash transactions without approval from the Foundation or the network’s developers. Using the blockchain does not make a product official. Official Zcash changes follow the Zcash Improvement Proposal process, which involves public specifications, community feedback, and coordination among developers and node operators. ZRC-20 does not appear anywhere in that process.
There is even a naming collision. ZetaChain already uses “ZRC-20” for its own omnichain token format, and the Zcash community discussed the same label years ago when debating token functionality. Meanwhile, actual Zcash development centers on the formal NU7 upgrade proposals, including reducing the block target from 75 seconds to 25 seconds while adjusting rewards to keep the issuance schedule intact.
Market Implications: Lesson for Every Altcoin Holder
This episode lands during a volatile stretch for ZEC itself. The privacy coin gained roughly 43 percent in the first week of September, broke above 1,000 USD, touched a multi-year high near 1,290 USD, pulled back toward 1,139 USD with about 17.2 million USD in long liquidations, then surged more than 20 percent to around 1,337 USD by Sept. 16 as traders watched the NU7 vote — all per earlier crypto.news reporting. High volatility plus a hot narrative is exactly when unofficial token schemes flourish.
For US investors especially, a third party’s use of an established blockchain settles nothing about how regulators may treat its token. In August, the SEC proposed crypto-asset rules covering certain investment contracts, with possible exemptions for offerings up to 5 million USD over four years or up to 75 million USD in a 12-month period. Whether CASH fits any framework depends on how it is issued, marketed, and sold — and, notably, the reviewed project material does not clearly identify a company, legal entity, or named developers behind it.
The Verdict: Verify Before You Mint
The playbook here applies far beyond Zcash. When a token announcement appears on an official-sounding channel, check whether the network’s actual governance process — a ZIP, an improvement proposal, a foundation statement — backs it. An anonymous team, an unofficial standard, and a borrowed name are three red flags stacking on top of each other.
Zcash the network is functioning fine, with real upgrades moving through its formal process. But ZRC-20 and CASH are, for now, exactly what the Foundation says they are: someone else’s project riding on its rails. Treat them accordingly.

the announcement came from the Foundation own X account and they still disowned it hours later? someone got phished or someone is getting fired today
@zkshield_99 more likely a scheduled post for an unofficial drop slipped through. the CASH token repo had zero Foundation commits, this was never their build
zero foundation commits in the CASH repo is the smoking gun tbh. someone queued promo for a third party drop and nobody checked the schedule
zero foundation commits and it still got promo from the official account. whoever queued that post had access they shouldnt have had
checked the repo after your comment. zero foundation commits and a promo slot on the official X anyway, whoever queued that post owes the whole community an explanation
the scheduled post excuse only holds if several people can queue to the main account, which is its own problem for a foundation this size. one unreviewed slot reaching the official X should not be possible
Storing token instructions as JSON inside encrypted memo fields was always a hack. Independent indexers literally cannot read shielded notes without opt-in, so good luck trading ZRC-20 anywhere.
512 bytes per memo field for an entire token standard lol, Malin is right, that constraint alone screams side project
512 bytes was never a design decision, it was legacy memo constraints from the start. the whole standard reads like a weekend build
Storing token data as JSON in 512-byte shielded memos is clever and completely indexer-hostile. No wonder third parties are struggling to track it.
Bigger issue to me is how the promo went out from the Foundation X account at all. Compromised or careless, either answer is bad.
compromised, careless, or complicit, and none of those three look great on a foundation roadmap tbh
careless is the charitable read. foundation accounts posting third party drops is how takeover rumors start and never fully die
indexer hostile is putting it nicely. try building wallet UX around 512 byte shielded memos, its a nonstarter before you even get to the JSON parsing
Naming an unofficial token CASH was the loudest red flag. If a disclaimer was needed, the project already failed.
