Claus (CLAUS) is an Ethereum token with a Uniswap v4 pool whose trading mechanics can change after launch. Replaceable hook code currently supports fee-funded token buybacks and burns, liquidity funding, and a weather-dependent allocation between burns and liquidity. The Claus agent conducts conversations, research and idea gathering on X. The project publishes its current mechanisms, onchain sources and a chronological Journal at claus.si. The official token address remains the same when hook implementations change.
