TL;DR
- Uniswap deployed Continuous Clearing Auctions on the Base network, offering fully on-chain token launches through auctions.
- The CCA model sells tokens block by block and automatically seeds liquidity into Uniswap v4 pools at the final auction price, avoiding manual configuration.
- Access to CCA on Base is open and permissionless, allowing teams to adjust auction parameters.
Uniswap has deployed its Continuous Clearing Auctions (CCA) framework on the Base network, enabling developers to launch tokens fully on-chain with structured auctions, price discovery, and automatic liquidity provisioning. The mechanism is available to all teams using Uniswap v4 on this Ethereum layer-2 network.
With CCA live on Base, tokens are sold gradually through block-by-block auctions. This mechanism generates a progressive market price before open secondary trading begins. Once the auction ends, liquidity is automatically seeded into a Uniswap v4 pool at the final cleared auction price, removing the need to manually configure pools after launch.
Developers can adjust parameters such as auction duration, allocation structure, and other sale rules, making the entire process fully transparent and entirely on-chain. The core logic follows the same block-by-block clearing process across all supported projects.
Uniswap Seeks to Optimize Token Launches
The model is designed to mitigate common token launch risks, including supply concentration, price manipulation, and the dominance of optimized traders in the early blocks. Phased selling distributes supply over time and allows price formation to develop gradually. Teams can rely on the final auction price when configuring pools, reducing the need to estimate an initial listing price.
Access to CCA on Base is open to all Uniswap developers and does not require approvals or whitelists. Projects can integrate auctions, price discovery, and liquidity provisioning through the same contract, maintaining non-custodial execution and aligning liquidity creation with actual demand.
Availability for All Developers
The rollout of CCA on Base is part of Uniswap v4’s broader expansion, which also includes deployments on networks such as Monad and X Layer, as well as partnerships with firms like Revolut for fiat on-ramps and Ledger for secure swaps via API. CCA had already been adopted by projects such as Aztec Network to establish initial pricing and liquidity during their token launches
