Uniswap Launches Continuous Clearing Auctions on Base
Uniswap has rolled out its Continuous Clearing Auctions (CCA) feature on Base, giving developers a permissionless way to launch tokens on-chain with built-in price discovery and automatic liquidity provisioning.
The rollout was confirmed on Jan. 22, with CCA now available to builders using Uniswap v4 on the Base network.
How CCA works on Base
The CCA framework allows teams to conduct fully on-chain token auctions that sell supply gradually rather than in a single event. Bids are cleared block by block, allowing a market-driven price to form organically before public trading begins.
Once an auction concludes, liquidity is automatically seeded into a Uniswap v4 pool at the final cleared price. This removes the need for manual pool creation and helps reduce volatility and price distortions often seen during token launches.
The system is designed to mitigate common launch issues such as sniping, front-running, and bundled transactions, which can occur in fixed-price or single-moment launches. By spreading distribution over time, CCA aims to create a fairer and more transparent starting point for new tokens.
Auction parameters can be customized by teams, while keeping the entire process fully on-chain and verifiable.
Open access for Base developers
The CCA feature is permissionless, requiring no approvals or special access. Any team building on Base can integrate CCA into their token launch process.
The feature was first introduced in late 2025 and has already been used by projects such as Aztec Network for early-stage price discovery and liquidity setup.
Why the rollout matters
By bringing CCA to Base, Uniswap is expanding structured token launch tools to one of the most active Ethereum layer-2 networks. Developers can now manage auctions, pricing, and liquidity through a single Uniswap v4 workflow.
The move strengthens Base’s growing DeFi ecosystem, particularly for teams seeking alternatives to private sales or unstable fair-launch models.
Uniswap has continued expanding its v4 infrastructure across multiple networks in recent months. In addition to launches on Monad and X Layer, the protocol has also integrated with partners such as Revolut for fiat access and Ledger for secure swaps via its trading API.
