The Ethereum ecosystem meme issuance platform jump.fun has officially launched on the mainnet, aiming to provide a one-stop solution for developers and users for meme coin issuance and trading. It is reported that jump.fun allows users to fill in basic token information (name, symbol, and simple description) to complete meme issuance, and each newly issued token immediately receives a free liquidity loan of 6 ETH for providing initial liquidity on Uniswap. The 'LiqWar' model proposed by jump.fun allows meme coins to compete in batches in the form of liquidity competitions, with the winner's liquidity being multiplied. Additionally, 100% of the platform's revenue is used to buy back JUMP and is distributed proportionally: 25% for token burning, 25% to support protocol development, and 50% allocated as community rewards.
