Privacy Coins Zano and Firo Trend as Demand for Untraceable Transactions Grows
Zano (ZANO) and Firo (FIRO) both appeared in CoinGecko’s trending assets list on May 14 as the privacy coin sector drew renewed attention. Zano rose 3.1% in 24 hours to $11.61, putting its market capitalization at $178 million.
Firo gained 4.5% over the same period to $1.29, with a market cap of $24 million. The pairing of two structurally different privacy protocols in the same trending window points to a broader shift in trader attention toward fungibility-focused cryptocurrency assets.
What Makes Zano and Firo Different
Zano is a privacy-centric blockchain launched in 2019.
It uses ring signatures and stealth addresses to obscure the sender, receiver, and amount in every transaction. Ring signatures work by bundling a real transaction with a set of decoy signatures, making it cryptographically impossible to identify which participant actually signed.
Stealth addresses generate a unique one-time address for every payment, so recipients cannot be linked across transactions by on-chain analysis alone.
Firo takes a different approach. The protocol uses a cryptographic method called Lelantus Spark, which allows users to burn coins into an anonymity pool and then redeem new coins from that pool with no traceable link to the original input.
The burn-and-redeem mechanism provides strong unlinkability without requiring the ring-signature construction Zano uses. Firo has been developing privacy technology since its original launch as Zcoin in 2016 and rebranded to its current name in 2020.
The two protocols represent the two dominant engineering philosophies in the privacy coin space: ring-signature-based obfuscation, shared by Monero’s design lineage, and zero-knowledge-proof-adjacent pool systems, which Firo pioneered alongside developments at Zcash (ZEC).

Why They Are Trending Together on May 14
Privacy coin activity tends to cluster around two catalysts: macro risk-off sentiment that drives users toward censorship-resistant alternatives, and regulatory developments that heighten awareness of transaction surveillance.
On May 14, both dynamics are present. The Senate Banking Committee advanced the CLARITY Act earlier this week, a bill that would establish a comprehensive framework for digital asset classification.
Among its provisions, the bill addresses reporting obligations for cryptocurrency transactions above certain thresholds.
That regulatory backdrop has historically coincided with spikes in interest for assets offering baseline transaction opacity. Zcash, which sits at market cap rank 16 and has faced repeated scrutiny over its privacy features, did not appear in the trending cohort on May 14.
Zano and Firo, which sit well below Zcash by market cap, drew disproportionate attention relative to their size.
Zano’s $178 million market cap and $2 million in 24-hour trading volume represent a small absolute market. Firo’s $24 million market cap and $522,000 in daily volume are smaller still.
High trending visibility with low absolute volume is a pattern often associated with speculative retail rotation rather than structural institutional accumulation.

The Broader Privacy Coin Landscape
The privacy coin sector has faced persistent pressure from regulators and exchanges in recent years. Several major centralized exchanges delisted Monero and Zcash between 2021 and 2024, citing anti-money-laundering compliance concerns.
That delistings cycle reduced accessible on-ramps for privacy assets and suppressed volume across the category. Zano and Firo, both smaller by market cap, were less affected by the delistings wave because they had narrower centralized exchange footprints to begin with.
Monero, the category’s dominant asset by market cap and the protocol most frequently cited in regulatory enforcement actions, has experienced a prolonged period of regulatory attention.
That attention has not disappeared, but the privacy coin sector’s overall ranking in regulatory priority appears to have shifted as regulators have focused more intently on stablecoin issuers and large centralized exchange compliance since 2025.

What to Watch
The durability of Zano and Firo’s trending status will depend on whether the CLARITY Act’s final text includes specific provisions targeting privacy coins. If it does, the attention could translate into sustained demand.
If the legislative language proves less restrictive than feared, the rotation may fade within days. Traders watching this sector should track the $178 million Zano market cap level as a key threshold.
A sustained break above $200 million would represent the first meaningful upward step in Zano’s market cap history in over 18 months.
