Uniswap Labs has deployed Continuous Clearing Auctions (CCA) on Arbitrum One, giving builders a new onchain way to launch tokens with open participation and transparent pricing. With the rollout, Arbitrum teams can run token auctions onchain, discover a clearing price through live bids, and then seed liquidity on Uniswap v4 at that same market price. Uniswap said CCA is permissionless and free to use, with guides available for teams that want to integrate it.
CCA is built to address common launch problems that crop up during early token distribution. The fixed price sales may result in rushes and mispricing, and the Dutch auctions may provide a reward to timing rather than valuation. One-shot auctions are prone to last-minute sniping, and even bonding curves can be manipulated in the thin liquidity case.
A lot of launches are also dependent on centralized market makers, which introduces a sense of trust and potentially moves value off-user. CCA replaces those approaches with an auction that clears continuously and spreads demand across time.
Arbitrum also promoted the deployment as a new option for fairer token launches on Arbitrum One. In a post on X, the network said CCA supports market-driven price discovery and automatic liquidity seeding while running on its platform and liquidity ecosystem. Community responses have lauded the launch as useful for both sides of the market, since builders get distribution and liquidity tooling, and users get an auditable process.
🔸 How Uniswap’s CCA Runs Auctions and Seeds Liquidity
A Continuous Clearing Auction starts when a project commits a portion of its token supply and sets parameters such as duration and a floor price. Participants then place bids using a budget and a maximum price they are willing to pay. Instead of selling everything at once, CCA releases tokens over time using a block-by-block schedule.

Uniswap Labs has officially rolled out its Continuous Clearing Auctions (CCA) mechanism directly on the Uniswap web interface, marking the first time this on-chain liquidity auction model has been widely accessible to the public. The move could significantly reshape how new tokens are launched and how liquidity is formed on decentralized exchanges across the Ethereum ecosystem.
CCA is a permissionless, fully on-chain auction system initially introduced as a concept late last year. It is designed to improve price discovery for newly launched tokens or assets with limited liquidity. By integrating CCA into Uniswap’s frontend, users can now easily discover active auctions, place bids, and receive tokens directly within the platform—without relying on third-party interfaces.
According to Uniswap Labs, traditional token launches often involve liquidity formation happening behind closed doors. This lack of transparency can result in thin order books, sharp volatility, and unfair advantages for automated trading bots once public trading begins. CCA aims to solve these issues by making the entire process transparent and verifiable on-chain.
Under the CCA model, token distribution, pricing, bidding, and allocation occur openly on the blockchain. Instead of a sudden liquidity injection that invites aggressive “sniping” by bots, tokens are introduced into the market gradually. Prices adjust dynamically based on real demand, while an automated system continuously calculates a fair market-clearing price.
One of the key benefits of CCA is its ability to reduce bot-driven manipulation during token launches. By slowing down liquidity deployment and matching supply with genuine buyer interest, CCA minimizes extreme price swings and creates a more orderly market environment.
Once an auction concludes, participants automatically receive their allocated tokens, and real liquidity is seamlessly added to a Uniswap v4 trading pool, enabling immediate secondary market trading without abrupt disruptions.
CCA is not limited to brand-new assets. Existing projects can also leverage the mechanism to distribute additional token supply or establish initial liquidity in a transparent and community-driven manner. This effectively “crowdsources” price discovery and reduces reliance on centralized decisions.
Although CCA does not alter Uniswap’s core protocol, its prominence on the official frontend could fundamentally change token launch workflows on DEXs—making them fairer, more decentralized, and less prone to early-stage manipulation.
The smart contracts powering CCA are already live on Ethereum mainnet, Unichain, and Layer 2 networks including Arbitrum and Base.
Uniswap highlighted Aztec as the first project to utilize CCA for token distribution in November. The auction reportedly raised $60 million from over 17,000 participants, with no observed cases of bot sniping or automated manipulation. The entire process was fully on-chain, allowing real-time monitoring of market formation.
Looking ahead, Uniswap Labs plans to prominently display ongoing and upcoming CCA auctions directly on its main interface, eliminating the need for projects to build custom frontends for each launch. Developers will also be able to customize key auction parameters such as token supply, starting price, auction duration, and verification tools—including integrations like ZK Passport.
By pushing transparency, fairness, and automation to the forefront, CCA could mark a major evolution in decentralized token launches and on-chain liquidity formation.

Uniswap: The Unmissable Giant of Decentralized Finance#uniswap $UNI
If Decentralized Finance (DeFi) had a capital, it would be called Uniswap. Launched in 2018 on the Ethereum blockchain, this protocol has become the central pillar of the sector by enabling cryptocurrency exchanges without intermediaries, without registration, and without order books.
The Concept: The Automated Market Maker (AMM)
Unlike traditional exchanges like Binance or Coinbase that use "order books" (buyers vs sellers), Uniswap uses an automated market maker (AMM) model.
