KuCoin Community Chain, or KCC Chain, is a public blockchain being developed by the KuCoin community.
As a high-performance platform, KCC Chain boasts higher throughput and lower transaction fees than Ethereum and many other blockchains, but is undeniably more centralized, due there currently being just a dozen nodes involved in maintaining its integrity.
KuCoin Community Chain is unusual among blockchains in that instead of creating an entirely new gas token, the developers opted to incorporate the pre-existing KCS token instead. As a result, users need to spend KCS when submitting transactions on the blockchain.

How Does It Work?
Due to its relatively low activity, most blocks remain empty, meaning the platform generates very little in the way of transaction fee revenue. According to data from the official KCC Chain block explorer, daily transaction fee revenue generally hovers between $150-$300/day, to be shared between participating nodes.
As of writing, KCC Chain has a total of 12 nodes in operation, one of which has been inactive for more than a month. The platform is expected to support up to 29 validator nodes. New validators can only be voted into position by existing validators.
The KCS token is now used for paying for smart contact operations and regular transactions on the KCC blockchain.
Assets can be migrated to/from KCC Chain through the use of the KCC Bridge. This currently supports transfers between KuCoin Community Chain and Ethereum, BNB Chain, Polygon, Fantom, and Avalanche.
What Makes KCC Chain Unique?
KCC Chain faces strong competition from other, currently more successful exchange-associated blockchains, including Binance’s BNB Chain, OKEX’s OKC Chain, and Crypto.com’s Cronos Chain.
To help it succeed in an increasingly competitive layer-1 landscape, KCC Chain includes a number of distinguishing features.
Unlike many other exchange-associated blockchains, KuCoin Community Chain is not owned and operated by a centralized exchange. Instead, it is being built by members of the KuCoin community. Because of this, it claims to be more decentralized than many of its competitors, since it is free to evolve as per the whims of the community — rather than in response to regulations or the will of its creators.
KCC Chain has a block time of just 3 seconds (the same as BNB Chain). Because of this, the average transaction will typically achieve finality within 3 seconds. This makes it around four times faster than Ethereum, which currently has a block time of ~13 seconds.
Low transaction fees
KCC Chain is currently one of the cheapest blockchains by average transaction fee.
Since the platform is relatively inactive, the average transaction fee currently hovers around $0.01. This, however, can be expected to increase if competition for block space grows — e.g. if KCC Chain’s DApp ecosystem expands and/or if its user base grows.
To put this into perspective, the average Ethereum transaction fee is around $1.5 whereas the average fee on Solana is 0.000005 SOL (equivalent to <$0.001).
Does KuCoin Community Chain Have Any DApps?
Despite launching its mainnet in June 2021, KuCoin Community Chain has so far seen relatively little uptake among developers, and just a small handful of applications are currently live on the platform.
The three most popular in terms of their total value locked (TVL) are:
- MojitoSwap: An automated market maker running exclusively on KCC. The platform allows users to trade digital assets and provide liquidity to earn yields in the form of trading fees. Like many AMMs, it also features a variety of yield farms, in which users can stake their MojitoSwap LP tokens to earn additional rewards.
- KuSwap: Arguably an entire DeFi ecosystem into itself, KuSwap is similar to MojitoSwap in that it includes both AMM and yield farm functionality. But this is extended with additional features like an NFT marketplace, NFT trading battle game, lottery, and vault system. It also has its own IGO + IDO incubator and launchpad, which has hosted 4 projects as of writing, raising $1.16 million in total.
- KillSwitch: A DeFi yield aggregator, KillSwitch allows users to maximize the yields they earn on their KCC Chain-based assets through the use of a variety of specialized tools. Some of its additional features include an automated take profit and stop-loss tool, kill position option, and boost tool — all of which are designed to increase yields and minimize losses.
In the last year, the platform has seen the total value locked (TVL) in its DeFi protocols swell from $0 to over $76 million at its peak. The vast majority of this TVL is associated with MojitoSwap, which has an impressive dominance of more than 86%. Other DApps on KCC Chain currently have a TVL of under $1 million.
Overall, more than two dozen DApps are operating on KCC Chain, but most of these have very few users and limited utility.
To help expand its ecosystem and build out its DApp landscape, KuCoin Community Chain recently announced a $50 million ecosystem accelerator program.
It remains unclear whether the program has been a success. KCC Chain remains relatively underdeveloped compared to competing EVM chains.
