We explored the lifecycle of Solana DEX traders (the time span from the first to the last DEX transaction) and filtered out new addresses whose first DEX transaction occurred within the past 24 hours. We discovered several interesting insights. - The total number of Solana DEX trading addresses exceeds 750 million, but 96.6% of these addresses have a lifespan of less than 24 hours, with an average lifespan of approximately 15 minutes. Most of these addresses are likely used to pump new Memecoin trading volume. - Solana DEX traders have a high level of address stickiness. The number of addresses with a lifespan of 1 day to 1 week, 1 week to 1 month, 1 month to 1 quarter, and 1 quarter to 1 year is relatively close. Furthermore, the number of addresses with a lifespan of 1 quarter to 1 year is higher than those with a lifespan of 1 week to 1 month or 1 month to 1 quarter. - There are over 1.8 million addresses with a lifespan of more than 1 year, with an average lifespan of 655 days.
