Uniswap deploys Continuous Clearing Auction token launch feature to Base

Uniswap rolled out its Continuous Clearing Auctions feature on Base, giving developers a new way to launch tokens on-chain with built-in price discovery and liquidity setup.

Summary

• Uniswap’s CCA feature is now live on Base for permissionless token launches.
• The system discovers a market price before seeding liquidity on Uniswap v4.
• The rollout follows early CCA use in late 2025 and expands access to Base builders.

Uniswap has introduced its CCA feature on Base, giving developers a new way to launch tokens on-chain with built-in price discovery and automatic liquidity.

Uniswap confirmed the rollout on Jan. 22, with the CCA framework now available to builders using Uniswap (UNI) v4 on the Base network.

What the CCA deployment on Base enables

With CCA live, teams can run fully on-chain token auctions that sell tokens gradually rather than all at once. The process clears bids block by block, allowing prices to form naturally before trading begins.

After an auction finishes, liquidity is added automatically to a Uniswap v4 pool at the final cleared price. This removes the need for manual pool creation and helps avoid common launch problems tied to sharp price swings at listing.

Continuous Clearing Auctions have officially been deployed on @base, that means any Based builder can:

The feature is open to all Base developers and does not require approvals or special access. Any team building on the network can use CCA as part of their launch process.

The auction model is meant to create a fairer starting point for new tokens. Instead of fixed-price sales or single-moment launches, distribution happens over time, reducing the impact of sniping, front-running, and bundled transactions.

Teams can also adjust auction settings to fit their needs while keeping the entire process on-chain and transparent.

CCA was rolled out in late 2025 and has already been used by projects such as Aztec Network for early price discovery and liquidity setup.

Why the Base rollout matters

Uniswap is making structured token launches accessible on one of the busiest Ethereum (ETH) layer-2 networks by expanding the feature to Base. Developers can now handle auctions, pricing, and liquidity through a single workflow on Uniswap v4.

The update adds to Base’s growing decentralized finance toolkit, especially for teams moving away from private sales or unstable fair-launch models.

Uniswap has been expanding its v4 tools across several chains in recent months. Along with integrating with partners like Revolut for fiat access and Ledger for safe swaps via its trading API, the protocol has also gone live on networks like Monad and X Layer.
