Kleros (PNK): What It Is, Uses and Risks

Kleros is a dispute resolution layer built on blockchain technology. The project says it offers fast, secure and affordable arbitration for a wide range of disputes. Instead of sending a case to one court or company, it connects the parties with jurors who have the skills needed to judge the matter. Kleros describes this as crowdsourcing, which draws on a large, global pool of people rather than a fixed panel.

The project says blockchain records help keep evidence intact, make jury selection visible and support incentives for honest rulings. Because the project describes its services in broad terms, readers who want current details on which disputes it handles, and how its court products work, should read the official project materials and recent documentation.

PNK is the native token of the Kleros system. Public reporting and project descriptions say it is used for staking, for juror selection and for incentives that encourage fair dispute outcomes. In general terms, staking means locking tokens as a commitment to take part in the system. Jurors who participate are rewarded for rulings the system considers sound, which is meant to push the network toward honest judgments.

A 2026 guide describes Humanity Court, a part of the system that resolves disputes about identity verification for Proof of Humanity, a protocol that maintains lists of verified unique people. Staking is part of that process too. An older 2020 proposal listed PNK uses such as reward programs, team compensation and over-the-counter sales. Those were historical allocation notes, so the current use of tokens may differ.

Market figures change constantly, so the numbers below are snapshots taken from data dated 2026-11-05 and should not be relied on for current decisions. At the time of writing, PNK traded at about 0.0082 US dollars, with a market capitalization of about 7.5 million dollars and a 24-hour trading volume of about 25,000 dollars. The token ranked around 1,444th by market capitalization. Its price was down about 59 percent over the past year.

Supply is roughly 915.5 million PNK, both circulating and total, and no maximum supply is listed in the data. The all-time high was about 0.38 dollars on May 10, 2021, and the all-time low was about 0.00196 dollars on September 11, 2018. Trading volume this low can make prices move sharply on small trades. This section describes past and recent data only and is not a forecast of future prices.

PNK is issued on Ethereum, on xDai (the chain now known as Gnosis Chain) and on Arbitrum. It is not the native token of any single blockchain, which means each network has its own version of the token with its own contract address. Some market data sites group it under the Gnosis Chain and Ethereum ecosystems.

Because the same token exists on several networks, the version you hold matters. Moving tokens between networks usually requires a bridge or an exchange that supports the chain in question. Before sending funds, confirm the network and the contract address using official project channels, and check that your wallet supports the network you intend to use.

Several risks apply. PNK's price has been volatile over its history, and its low trading volume can make it hard to sell at a predictable price. The value of the token is tied to the success of a project whose outcomes depend on juror behavior, participation and the design of its incentives. Smart contracts can contain bugs, and blockchain transactions are generally irreversible. Scammers also create fake tokens and fake sites that imitate well-known projects.

For storage, many people use a self-custody wallet, where they control the private keys or recovery phrase. Never share a recovery phrase, and be cautious with unsolicited messages or links.
