What is zk402 (ZK402)?
zk402 is a next-generation privacy protocol designed to bring confidential, verifiable, and seamless on-chain transactions to the broader blockchain ecosystem. The project was created to combine zero-knowledge cryptography with the x402 payment infrastructure, forming a system where users can transact freely without revealing sensitive information while maintaining full on-chain validity. Today, most blockchain transactions are fully transparent and easily traced, which exposes financial data and limits privacy.
How does zk402 work?
zk402 is built to solve this problem by providing a privacy layer that protects users and businesses while keeping transactions trustless and verifiable. The core of zk402 enables private and secure transfers across more than 2800 supported coins and tokens. This allows users to transact using the assets they already hold while ensuring that the transaction amounts, sender, and receiver details are hidden using zero-knowledge proofs. Even though transaction details are shielded, all transactions remain verifiable on-chain, offering a balance between confidentiality and transparency.
What is zk402 used for?
This design makes zk402 suitable for personal financial protection, business payments, and decentralized applications that require privacy without compromising compliance. For developers, zk402 offers an SDK and API that simplify the integration of privacy features into any application. The SDK is designed to be lightweight, efficient, and compatible with existing workflows, allowing developers to add private transfers, confidential balances, and secure interactions without needing advanced cryptographic knowledge.
Where can you buy zk402?
zk402 (ZK402) is traded on a wide range of centralized and decentralized exchanges. The most liquid markets for ZK402 sit on tier-1 venues - the sort of exchanges where institutional desks and professional market makers rebalance continuously - which is what keeps the spread tight and the last price tied closely to fair value.
You can open the Markets section above to see the live list of exchanges quoting ZK402, sorted by 24-hour volume. Each row links to the venue's trade page so you can go directly from research to execution without copying the ticker around by hand.
What is the daily trading volume of zk402 (ZK402)?
The reported 24-hour trading volume of zk402 is $18.68. Volume is a live reading of how much ZK402 changed hands across all tracked exchanges in the past day and tends to rise during periods of price discovery and fall during consolidation.
For traders, the ratio between volume and market cap is often more informative than either number on its own: a high vol-to-mcap ratio indicates liquid, actively traded supply, while a low ratio suggests that most holders are sitting on the asset.
What is the highest and lowest price for zk402 (ZK402)?
zk402 reached an all-time high of $0.00008841 on November 17, 2025, and an all-time low of $0.000002450 on February 6, 2026. It is currently trading -95.91% from its peak and +47.33% from its bottom.
The distance from ATH is a useful gauge of recovery potential during a bear market and of stretched positioning during a bull market. Combined with the all-time-low figure it provides a quick statistical frame for thinking about where ZK402 sits in its long-run price range.
What is the market cap of zk402 (ZK402)?
zk402's market capitalization is currently $3.61K, and it is ranked #11749 by market cap on Cryptopricing. Market cap is calculated as the current price multiplied by the circulating supply (998.66 million ZK402 are actively circulating today).
Market cap is a common but imperfect measure. It reflects the theoretical value of every circulating token at the current market price, but it doesn't capture how thin the top of the order book might be - an important caveat for tokens with low floats or illiquid cap tables.
What is the fully diluted valuation of zk402 (ZK402)?
The fully diluted valuation (FDV) of zk402 is $3.61K. FDV is a projection of what the market cap would be if every token that will ever exist - including those that have not yet been unlocked, mined or issued - were in circulation at the current price.
FDV is a useful second reading alongside market cap. A large gap between mcap and FDV signals that future token emissions could dilute current holders, while a small gap indicates that supply is already mostly out.
How does the price performance of zk402 compare against its peers?
Over the past 24 hours, zk402 has moved -3.20%. Over the past seven days, the change is +7.07%. Comparing these figures to the global crypto market cap change (shown in the ticker at the top of this page) tells you whether ZK402 is leading, lagging or tracking the broader market.
For deeper analysis, the categories strip on the home page groups coins by theme - Layer 1, Meme, DePIN, AI, RWA and so on - and lets you compare zk402 against its closest peers. The category detail pages surface the underlying coins and their seven-day sparklines in a single view.
How to store zk402?
Like any crypto asset, the right way to store ZK402 depends on how often you plan to use it. Long-term holders typically self-custody using a hardware wallet such as Ledger or Trezor, which keeps private keys offline and immune to most remote attacks.
For active traders, a reputable custodial exchange wallet can be appropriate, especially one with clear proof-of-reserves attestations. Whatever approach you choose, the most important rule is to keep your recovery phrase offline, never share it, and never enter it into a web form or attached to a DM - no legitimate support agent will ever ask for it.
