One of the loudest names in on-chain investigations has turned his attention to one of the strangest sales of the year: blockchain sleuth ZachXBT has publicly accused the zkSNARKs NFT project of extracting roughly 17 million USD from its privacy-first auction on Zcash — a sale that moved 8,000 encrypted “Zcash identities” and drew nearly 17,000 bids.
By Jordan Lee | September 20, 2026
The controversy centers on a project called zkSNARKs, which launched an auction built entirely around Zcash’s shielded transaction technology — the same cryptographic tool that lets the Zcash network hide sender, receiver and amount data. The sale offered 8,000 encrypted identities to bidders, and on September 17 it cleared at 1.5 ZEC per identity with 16,971 bids placed, according to Crypto Briefing. Two days later, ZachXBT alleged that the project extracted about 17 million USD from the auction while delivering what Crypto Briefing described as “minimal utility” to buyers.
The Hook: An NFT Sale Nobody Could See
Most NFT drops live in public: you can watch every bid, every wallet and every price on a block explorer. The zkSNARKs auction was the opposite. Because it ran through Zcash’s privacy machinery — zero-knowledge proofs called zk-SNARKs, which prove a transaction is valid without revealing its details — the sale was essentially invisible by design. Bidders participated without the usual public paper trail, an approach the project framed as a landmark privacy-first sale, as Coin Gabbar and other outlets reported when the 8,000 identities went live.
That privacy is exactly what makes the follow-up so awkward. When a sale cannot be publicly audited, the community has to rely on the project’s own accounting — and on investigators like ZachXBT, who built a reputation tracing funds through some of crypto’s biggest exploits, to raise red flags from the outside.
On-Chain Evidence: 16,971 Bids and a Hefty Haul
The numbers that are public tell a story of genuine demand. Crypto Briefing reported the auction cleared at 1.5 ZEC per identity with 16,971 bids — heavy participation for a niche, privacy-themed drop. The strong clearing price mattered because ZEC itself has been one of the market’s standout performers this year, riding a rally that pushed the coin into price discovery and drew fresh attention to the Zcash ecosystem, as our own coverage has tracked alongside KuCoin’s reporting on the ecosystem’s NFT boom.
But demand is not the same as value. The core allegation, as summarized by Hokanews and Crypto Briefing, is that the team behind zkSNARKs collected roughly 17 million USD through the auction while the identities themselves offer buyers little in the way of usable function — no clear governance rights, no obvious redemption path, and no demonstrated utility beyond the privacy branding itself.
The Core Conflict: Privacy Tech Versus Buyer Protection
The spat exposes a tension the NFT world has mostly avoided until now. Privacy-preserving sales are technically impressive — and they are also structurally harder to police. In a standard marketplace drop, a suspicious pattern of self-bidding or wallet clustering can be spotted within hours. In a shielded auction, the same behavior is hidden by the very feature being marketed. Buyers, in effect, traded transparency for exclusivity, and critics argue they got the worse end of the deal.
It is worth separating the technology from the team. Zero-knowledge proofs remain one of the most important innovations in crypto, powering everything from private payments to scalability research. An allegation against one project’s conduct is not a verdict against the cryptography — but it is a reminder that novel tech can be the best marketing cloak for an old-fashioned cash grab.
Market Implications: What This Means for NFT Buyers
For everyday collectors, the lesson is about defaults. When you buy from a marketplace with public records, the community can audit the sale after the fact. When you buy into a shielded or semi-private drop, you cannot — so the diligence has to happen beforehand. Questions worth asking of any similar project: Who is the team? What exactly does the token or identity confer? Where do the proceeds go, and is there any lock-up or accountability for them?
The timing also matters for the Zcash community. The ecosystem has enjoyed a wave of positive attention this year, from price strength to institutional products tied to the coin. A headline-grabbing accusation of a 17 million USD extraction is the kind of story that can cool speculative enthusiasm for ecosystem experiments — even ones that, unlike this sale, deliver real utility.
The Verdict
The zkSNARKs saga is still unfolding: an accusation is not a conviction, and the project has not had its say in the headlines captured so far. But the episode already delivers a clean warning. Privacy technology and buyer protection are pulling in opposite directions, and when a sale is invisible by design, the burden of proof shifts entirely onto the seller’s reputation. If a drop cannot show its work, treat the hype as unverified — however elegant the cryptography behind it.

16,971 bids on 8,000 encrypted identities and nobody could watch a single wallet bid. you could not design a better setup for a 17m cash grab
1.5 ZEC per identity sounded cheap until you remember the whole point was nobody could see who got what. lmao
8k identities at 1.5 ZEC each while ZEC is in price discovery, of course the haul looks big. zachxbt doing god work as usual tho
fair point on ZEC being in price discovery, but 1.5 ZEC a head was still a choice. they could have priced lower, they chose not to
zachxbt again with the receipts. the minimal utility line is doing heavy lifting, they sold privacy cosplay and walked
privacy cosplay is the perfect phrase honestly
16,971 bids on something nobody can audit. the privacy pitch was the whole product and now nobody can verify where the 17M went. poetic honestly
^ exactly. you cant build a privacy-first sale and then expect people to trust your own accounting after zachxbt calls it extraction
the wildest part is the shielded pool means zachxbt had to build the case from bids and payout timing outside zcash. respect the effort
