Uniswap has rolled out continuous liquidation auction functionality on Base, giving developers a new way to launch tokens on-chain with built-in price discovery and liquidity settings.
summary
- Uniswap's CCA feature is currently running on Base for unauthorized token launches.
- The system detects market prices before seeding liquidity into Uniswap v4.
- This rollout expands access to Base Builder following initial CCA availability in late 2025.
Uniswap introduces CCA functionality to Base, giving developers a new way to launch tokens on-chain with built-in price discovery and automatic liquidity.
Uniswap confirmed the rollout on January 22nd, making the CCA framework available to builders using Uniswap (UNI) v4 on the base network.
What is possible by introducing CCA to Base
CCA Live allows teams to run fully on-chain token auctions that sell tokens in stages rather than all at once. This process clears bids block by block, allowing prices to form naturally before trading begins.
When the auction ends, liquidity is automatically added to the Uniswap v4 pool at the final liquidation price. This eliminates the need to manually create pools and avoids common launch issues associated with rapid price changes when listed.
Continuous liquidation auctions are officially deployed to @base. In other words, a Based builder can:
→ Run a complete on-chain token auction
→ Know reliable market prices
→ Uniswap v4 bootstrap liquidity pic.twitter.com/OKkwI26Sm8— Uniswap Labs 🦄 (@Uniswap) January 21, 2026
This feature is open to all Base developers and does not require approval or special access. Teams building on the network can use CCA as part of their ramp-up process.
The auction model aims to create a fairer starting point for new tokens. Distribution occurs over time, rather than fixed-price sales or instant launches, reducing the impact of sniping, front-running, and bundling deals.
Teams can also adjust auction settings to suit their needs, with on-chain transparency throughout the process.
CCA will be rolled out in late 2025 and is already being used in projects such as Aztec Network for early price discovery and liquidity creation.
Why is the Base rollout important?
Uniswap is extending this functionality to Base to provide access to structured token launches on one of the busiest Ethereum (ETH) Layer 2 networks. Developers can now handle auctions, pricing, and liquidity through a single workflow on Uniswap v4.
This update adds to Base's ever-growing decentralized finance toolkit, especially for teams looking to move away from private sales and unstable fair launch models.
Uniswap has been expanding its v4 tool across multiple chains in recent months. In addition to integrations with partners such as Revolut for fiat access and Ledger for secure swaps via trading APIs, the protocol also went live on networks such as Monad and X Layer.
