Kadena (KDA): From a 650% Rally in 2021 to the End of the Kadena Organization

Update 25 September 2026: On 21 October 2025 the Kadena organization announced that it would cease all business activity and stop actively maintaining the Kadena blockchain. The network itself keeps running on independent miners, but KDA now trades at about $0.008 according to CoinGecko data from 25 September 2026, more than 99% below its all-time high of $27.64. The original article from November 2021 follows below as a dated snapshot, with outdated statements corrected.

What happened to Kadena after the 2021 rally?

This article first appeared on 9 November 2021, in the middle of a rally that had lifted KDA by roughly 650% in a single month. Two days later, on 11 November 2021, KDA set its all-time high of $27.64. From there the price went into a decline that lasted for almost four years.

The turning point came on 21 October 2025. In a public announcement on X, the Kadena organization said it was no longer able to continue business operations and would end all business activity and active maintenance of the blockchain with immediate effect. It kept a small team for the wind-down and said it would release a node update so the network could run without the company. According to CoinGecko, KDA fell from about $0.21 to about $0.09 within hours of the announcement.

The blockchain did not switch off. Kadena is a proof-of-work network, so blocks are produced by independent miners and not by the company that designed it. Since the wind-down, miners and community volunteers keep the chain alive. What is gone is the funded core team that drove development, partnerships and marketing. Anyone looking at KDA today is looking at a community-run network with a market value of under $3 million, not at the project that was described in 2021.

Kadena (KDA): What is Kadena coin?

KDA is the native coin of the Kadena public blockchain. It pays for computing power on the network in the same way ETH pays for transactions on Ethereum: miners receive KDA for producing blocks, and users pay transaction fees in KDA.

Kadena was built for scalability. Its proof-of-work design, called Chainweb, runs many individually mined chains in parallel that reference each other, which raises throughput on the base layer without a separate layer-2 network. Smart contracts on Kadena are written in Pact, a language designed to be human-readable and to support upgradeable contracts with formal verification.

Next to the public chain, Kadena also developed a private, permissioned blockchain called Kadena Kuro (formerly ScalableBFT), which used a Byzantine Fault Tolerant consensus mechanism and was aimed at enterprise use.

Why did KDA rise by almost 650% in 2021?

Several developments came together in October and November 2021. DeFi was booming, and new staking opportunities for KDA appeared on exchanges such as Crypto.com and CoinMetro.

The second driver was wKDA, a wrapped version of KDA on Ethereum that made the token usable in EVM-compatible DeFi applications. On 6 November 2021, Kadena announced on X that wKDA had been submitted to the Ethplorer token tracker, and said it planned bridges to other layer-1 networks such as Terra, Polkadot, Celo and Cosmos. Terra collapsed in May 2022, so that part of the plan never happened.

Kadena also promoted NFTs and gaming on its chain. At the end of October 2021 it announced that the UFO token project would build an NFT gaming platform on Kadena.

What was special about Kadena's tokenomics?

According to the Kadena documentation, the total supply of KDA is capped at 1 billion coins, to be mined over a period of around 120 years. Because Kadena is a public proof-of-work chain, the largest share of coins is issued through mining rewards and not through a sale.

At the time the original article was written, KDA traded at $17.15. Its monthly return stood at almost +650%, its three-month return at almost +2,800% and its one-year return at around +7,600%.

What does the 2021 outlook look like in hindsight?

The original article argued that KDA could be profitable in the following weeks and months and should be seen as a long-term investment, comparing the market to the end of 2017. The comparison held in an unexpected way: just as in early 2018, the peak came almost immediately. KDA topped out two days after publication, and a holder who bought at $17.15 in November 2021 was sitting on a loss of more than 99% by September 2026.

The lesson from Kadena is not specific to one coin. A strong rally says little about whether a project can finance itself through a bear market. Current prices for the largest cryptocurrencies are on our crypto prices overview, and our guides explain how a blockchain works and what DeFi is.
