K21 (K21): What It Is, Uses and Risks

K21 (K21) is an Ethereum-based crypto token associated with a curated collection of 21 NFT artworks. Public descriptions present it as a way to get liquid exposure to an art vault holding those works. That does not necessarily mean each token gives its holder a direct, legally enforceable claim to a particular artwork. The precise ownership, governance, redemption, and other rights depend on the project’s current documentation and arrangements, which readers should check before relying on them.

K21 is categorized as an NFT-related token, but it is not itself one of the artworks. It is a fungible token: units are designed to be interchangeable, unlike unique NFTs. The project’s name and art-vault description explain its association with a collection of 21 works, but they do not establish how the collection is managed today or whether token holders can influence its decisions.

K21’s stated purpose is to connect a tradable token with exposure to a collection of NFT art held in a closed-end art vault. In principle, this gives people a token they can transfer or trade rather than requiring them to buy or sell an artwork individually. However, trading K21 does not automatically transfer ownership of any specific NFT artwork, and the token’s market price is not necessarily equal to the value of the art collection divided among token holders.

Public sources do not establish specific holder benefits such as voting rights, a claim on proceeds, or a redemption process. Treat those as unconfirmed unless current project documents explicitly describe them. Before using K21 for its art-related purpose, check what the token contract and the project’s legal and operating terms say about the vault, the artwork, and holders’ rights. A token’s description alone is not a guarantee of access to, or ownership of, the underlying assets.

K21 was issued on Ethereum and is an ERC-20 token, rather than the native asset of a blockchain. This means it can be held in compatible Ethereum wallets and may be transferable through supported Ethereum applications. Public sources list Ethereum as its issuance chain; it does not identify other networks where K21 is issued. Be cautious with tokens bearing the same name on other chains, since they may not be the same asset.

K21 has a maximum and total supply of 21 million tokens. About 18.45 million were reported as circulating as of 2026-11-05, with the remainder not counted as circulating in that figure. Supply classifications can change, so check current contract and market information if the exact amount matters. The 21-million cap is a token-supply limit; it does not indicate how many artworks the vault currently holds beyond its stated association with 21 works, nor does it define the value of each token.

As of 2026-11-05, K21’s reported price was about $0.0138, with a market capitalization of roughly $254,000 and a fully diluted valuation near $289,000. These are approximate snapshots, not fixed values. Reported 24-hour trading volume was about $2 at that time, indicating very limited activity in the tracked markets. With such low volume, a displayed price may not reflect what a holder could receive when selling a meaningful amount; trades can move the price sharply, and it may be difficult to find a counterparty.

Market capitalization is calculated using the circulating supply and price, while fully diluted valuation uses the total or maximum supply. Neither figure measures the value of the artwork held by the vault or guarantees that K21 can be sold at the quoted price. Historical highs and lows also do not predict future performance. Consider current liquidity and the project’s underlying documentation separately from any headline price or valuation.

K21 carries both crypto-market risk and art-asset risk. Its price can be volatile, and the very low reported trading volume as of 2026-11-05 may make buying or selling difficult. The value and condition of an NFT art collection can be hard to assess, and token holders’ rights may depend on legal structures and project operations. Smart-contract bugs, lost access credentials, phishing, and mistaken transfers are additional risks. Do not assume that holding K21 guarantees a share of sale proceeds or control over the artworks.

For storage, use a wallet that supports Ethereum ERC-20 tokens and protect its recovery phrase offline. Verify the token’s official contract details through reliable project documentation before adding or transferring it; a matching name or symbol is not enough to identify a genuine token. Never share a recovery phrase or sign a transaction you do not understand. A hardware wallet can reduce exposure of signing keys, but it cannot remove market, contract, or project risks.
