I did some basic tests, but it's different from what many of my friends thought. Indeed, coins can be issued on the SOLANA chain, but only on Pump and Launch Lab. And these two platforms are mainly for sending Memes. There are indeed three options for market making: 1. Volume (volume based market making) Theoretical core: Improve transaction activity and visibility. By frequently buying and selling (usually in pairs) to create a market appearance of "transactions occurring", improve candlestick and trading volume data. Emphasize the matching of buying and selling within the same transaction. Mainly to generate transaction volume. 2. Turnover cycle Theoretical core: circulating assets between wallets to increase turnover rate. It's not just about boosting or smashing the market, but about forming on chain liquidity activities through multi address asset rotation. The main focus is on creating turnover and increasing activity. 3. Robot price Theoretical core: Make directional interventions towards the target price. Converge the price towards the target value by continuously buying (pushing up) or selling (lowering). It is to set the high point and high point of the price, and achieve it through buying and selling. The essence of this tool should be on chain execution automation+multi wallet strategy tool, because they are all command line, without UI, and do not have the infrastructure for market making. So it's not very convenient to use for my friends. It is possible to use it as an automated execution tool. For example, sending a Meme and then performing simple operations on your own is still possible.
