This repo is an unfinished/untested experiment to create a compliant token sale contract following the regulatory guidance coming out of the XRP case.
Concept: https://jamesbachini.com/xrp-legal-case/
The idea is to have an ERC20 token which get's distributed to stakeholders in the project. A percentage of their holdings gets deposited to a Uniswap v4 liquidity pool. The pool includes a hook which allows VC's and crypto funds to buy tokens for a period of time with a minimum sale amount. Once the private round is over the hook is bypassed to enable public trading.
