Privacy Tokens Zano and Firo Trend Together as Demand for Untraceable Transactions Grows
Zano (ZANO) and Firo (FIRO) landed simultaneously on the CoinGecko trending list on May 13, the first time both privacy-focused tokens have appeared together in the same trending window in the current cycle. ZANO traded at approximately $11.31, down about 3.8% over 24 hours, with a market cap of $172 million.
FIRO traded near $1.25, down about 7%, with a market cap of $23 million. Both tokens are classified as privacy coins, a category of cryptocurrency designed to obscure sender identities, receiver identities, and transaction amounts on a public blockchain.
Their simultaneous appearance on the trending list signals a rotation of retail attention into the privacy coin sector that extends beyond any single project.
How Zano and Firo Work
Zano is a privacy-centric blockchain launched in 2019. The protocol uses ring signatures and stealth addresses to make transactions untraceable.
A ring signature groups a real transaction with a set of decoy inputs, making it statistically difficult to identify which input authorized the spend. A stealth address is a one-time address generated for each transaction, preventing outside observers from linking multiple payments to the same receiver.
Firo, formerly known as Zcoin, takes a different technical approach.
The protocol uses a zero-knowledge proof mechanism called Lelantus Spark, which allows users to destroy coins in one transaction and mint fresh, unlinkable coins in a subsequent transaction. Zero-knowledge proofs are cryptographic tools that allow one party to prove a statement is true without revealing the underlying data.
Firo’s approach provides strong unlinkability without requiring the trusted setup phase that earlier privacy coin architectures needed.
Both protocols operate independently of Ethereum (ETH) and Solana (SOL), running their own native chains rather than deploying as smart contract tokens.

The Privacy Coin Landscape in 2026
The privacy coin sector has historically operated under regulatory pressure in the United States and Europe. Monero (XMR) and Zcash (ZEC) have been delisted from multiple centralized exchanges in response to requests from regulators concerned about anti-money-laundering compliance. The Financial Action Task Force, the international body that sets standards for anti-money-laundering regulation, published guidance in 2021 classifying privacy coins as higher-risk assets requiring enhanced due diligence.
Despite that pressure, the sector has not collapsed.
A subset of users, including privacy advocates, journalists operating in restrictive jurisdictions, and cryptocurrency developers building confidential transaction infrastructure, has maintained consistent demand for privacy-preserving blockchain protocols. On-chain activity across privacy coin networks has grown modestly in the first half of 2026, partly driven by wider geopolitical concerns about financial surveillance.
Zano and Firo both sit below the top 200 and top 850 by market cap respectively, making them small-cap assets with limited liquidity outside specialist venues.
Their volume figures, $1.1 million for ZANO and $643,000 for FIRO on May 13, are modest. The trending signal reflects search and watchlist interest rather than large absolute trading flows.

Background
Firo rebranded from Zcoin to Firo in October 2020 after the project abandoned its original Zerocoin cryptographic scheme in favor of the more robust Lelantus protocol.
The rebrand coincided with a broader push to differentiate Firo from earlier-generation privacy coins that had been compromised by cryptographic weaknesses. Zano launched around the same period, positioning itself as a privacy chain with smart contract capabilities, a feature that Monero and older privacy coins do not support natively.
Both projects have operated with small, independent development teams funded through block rewards rather than venture capital.
That funding model limits development speed but also insulates the projects from investor pressure to compromise privacy features for exchange listing compliance.

What to Watch
The simultaneous trending of Zano and Firo suggests retail attention is cycling through the privacy coin sector broadly rather than concentrating in a single project. If that rotation extends to Zcash (ZEC) or Monero, it may reflect a more durable narrative shift.
The key risk for both tokens is regulatory action. Any exchange delisting driven by compliance pressure would sharply reduce liquidity and likely reverse recent price gains.
Developers and long-term holders should monitor the FATF guidance updates scheduled for later in 2026, which may further define expectations around privacy coin handling at regulated venues.
