Problem Statement

OverviewDeckFair Trade is a Uniswap V4 pool that launches tokens with safety guarantees for future token holders and traders. By leveraging Uniswap V4 hooks, projects can safely raise ETH, distribute tokens, pool liquidity, and put time-locks on tokens.BenefitsInstead of raising funds for a new token or project using Excel or a hot wallet, deploy Fair Trade and track liquidity raised for the project on the blockchain.Once the project creator is ready to launch the token (target ETH is raised), user callslaunchwhich will launch an ERC 20 token, distribute this token to initial liquidity providers, lock the token + ETH raised in a Uniswap V4 pool and then trading can begin.For the first year, trading can take place for anyone that is not flagged as a "funder" and the initial liquidity pool is locked.
