Privacy Cryptocurrencies

Cryptocurrencies with built-in privacy features — from untraceable to confidential transactions.

# Cryptocurrency Privacy Type Explanation
01 Monero Monero (XMR) Untraceable Monero integrated Seraphis and Triptych, enhancing privacy by optimizing ring signatures and reducing transaction size with Bulletproofs+, while maintaining stealth addresses and RingCT for full confidentiality. It is now preparing to adopt Jamtis, aiming to further improve scalability, privacy, and resistance to advanced blockchain analysis and potential quantum attacks.
02 Firo Firo (FIRO) Untraceable Firo uses Lelantus Spark, an advanced privacy protocol ensuring 100% private transactions by default: amounts, senders, and recipients are hidden via zk-SNARKs proofs, untraceable stealth addresses, and a trustless modular design. Spark also enables one-click transparent→private transactions, simplifying use while guaranteeing full anonymity.

The protocol is audited with no critical vulnerabilities, and adds features like Spark Names (human-readable addresses) and Spark Assets (custom private assets), boosting both privacy and usability.
03 Verge Verge (XVG) Untraceable Routes transactions through Tor and I2P networks. Wraith Protocol allows switching between public and private ledgers.
04 Dash Dash Confidential Optional PrivateSend feature mixes transactions using CoinJoin to obscure the transaction trail.
05 XELIS XELIS (XEL) Confidential MiCA and DIC8 compliant confidential transactions. Combines BlockDAG speed with built-in privacy at the protocol level.
