Owning ZKJ: Uses, Storage and Risks

Polyhedra Network describes ZKJ as the utility token of EXPchain, where it is used to pay transaction fees. That gives the token a stated network function, but it does not tell you how much demand there will be: fee use depends on people and applications using the network.

Before you use or hold ZKJ, check that the network you intend to interact with supports it and that you have selected the right chain. A token can appear in your wallet without being usable for every purpose on that network. ZKJ is also issued on Ethereum and BNB Chain, so a wallet balance on one chain is not automatically the same as a balance on another.

The project’s token utility is not a promise of price growth or income. Treat ZKJ as a volatile crypto asset, and do not rely on a forecast or a token’s stated role as evidence that it will retain value.

ZKJ is issued on Ethereum and BNB Chain. Polyhedra documentation also describes it as EXPchain’s native utility token. These network labels matter when you send, receive or withdraw ZKJ: your wallet and the destination must support the same network, or you could lose access to the tokens.

You can use a wallet that supports the relevant network, including compatible self-custody wallets, or keep ZKJ with a crypto exchange that lists it. An exchange may support withdrawals on only some networks, and availability can change. Check the withdrawal network and token details in the exchange and receiving wallet before confirming a transfer.

Do not choose a token contract address based on a name or symbol alone; scammers can create lookalike tokens. Confirm the network and contract through Polyhedra’s official channels or the platform you are using. If you are moving a meaningful amount, consider first sending a small test transaction and checking that it arrives on the intended network.

As of 2026-11-08, ZKJ’s reported supply is about 669.9 million circulating, out of a total and maximum supply of 1 billion. That leaves roughly 330.1 million tokens outside the reported circulating supply; this figure alone does not establish when or how those tokens may enter circulation.

A fixed maximum can help you understand the upper limit, but it does not prevent dilution for current holders if more of the existing supply becomes available. Check the project’s token distribution and release updates before making assumptions about future circulation. A circulating supply figure can also differ between data providers because their counting methods may not match.

ZKJ’s market value can change sharply even if its supply stays the same. Supply figures are not a measure of demand, liquidity or the ease of selling. Use dated figures when comparing them, and avoid treating market capitalization or fully diluted valuation as guaranteed value you could recover.

For self-custody, use a wallet that supports the network holding your ZKJ. Back up its recovery phrase offline, keep it private, and never type it into a website or share it with someone claiming to provide support. A hardware wallet can keep signing keys offline, but it cannot protect you if you approve a malicious transaction or send tokens to the wrong address.

Before transferring, check the network, recipient address and token details. Be cautious of unsolicited messages, fake airdrops and requests to connect your wallet or sign unfamiliar transactions. If you use an exchange, secure the account with a unique password and strong authentication, and understand that the exchange controls the keys while your tokens are held there.

ZKJ has experienced severe volatility: in June 2025, reports described a drop of more than 80% amid liquidity-provider withdrawals. That history is a reminder that liquidity can disappear and prices can move quickly. You could lose some or all of your funds, and no storage method removes market or network risk.
