Uniswap brings token launch auctions and price discovery to Base

• CCA runs fully on-chain auctions that clear bids block by block for gradual price discovery.
• After auctions end, liquidity is automatically added to a Uniswap v4 pool at the final cleared price.
• The model aims to reduce sniping, front-running, and bundled transactions during token launches.

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

The decentralised exchange confirmed the rollout on Jan. 22, with the CCA framework now available to builders using Uniswap v4 on the Base network.

The update expands Uniswap’s structured token launch tools to one of the busiest Ethereum layer-2 ecosystems, offering teams a single workflow for auctions, pricing, and liquidity.

With CCA now live for Base developers, projects can run token sales that settle gradually over time rather than relying on one-time listings or fixed-price launches that can trigger sharp price swings.

What CCA does on Base

CCA allows teams to run fully on-chain token auctions where tokens are sold gradually instead of all at once.

The mechanism clears bids block by block, which helps prices form naturally before open trading begins.

Once the auction ends, liquidity is added automatically to a Uniswap v4 pool at the final cleared price.

This reduces the need for teams to manually create a pool after launch and aims to avoid common listing issues linked to sudden volatility at the start of trading.

Developers can also adjust auction settings to fit their launch requirements while keeping the entire process on-chain and transparent.

How auctions reduce launch risks

The model is designed to create a fairer starting point for new tokens by spreading distribution over time.

Rather than concentrating activity into a single launch moment, CCA introduces a phased selling process that can lower the impact of sniping, front-running, and bundled transactions.

By clearing bids over multiple blocks, the auction format supports more gradual price discovery.

This can help reduce sharp dislocations that often happen when tokens go live with limited liquidity or when early trading activity is dominated by automated strategies.

For teams, this approach bundles the early steps of a token launch into one on-chain flow, covering auction mechanics, pricing formation, and liquidity provisioning without requiring separate manual actions.

Open access for all Base developers

Uniswap’s deployment on Base is open to all developers building on the network. The feature does not require approvals or special access, meaning any team can integrate CCA into its token launch process.

This open availability may appeal to projects looking for alternatives to private sales or unstable fair-launch formats.

It also supports teams that want a more standardised on-chain approach to distributing tokens while setting up liquidity in a predictable way once the auction completes.

With CCA, teams can rely on the auction’s final cleared price to determine the pool setup, rather than selecting an initial listing price independently.

Uniswap’s wider v4 expansion

The Base rollout follows Uniswap’s broader expansion of v4 tools across multiple chains in recent months.

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.

Uniswap has also been integrating with partners such as Revolut for fiat access and Ledger for safe swaps via its trading API.

Separately, the protocol has gone live on networks including Monad and X Layer.

By bringing CCA to Base, Uniswap is extending structured launch infrastructure into a major Ethereum layer-2 environment, while continuing to expand its product suite and chain support across decentralised finance.
