Frequently asked questions
What is liquidity decay?
For each token that graduated on a UTC day: pool liquidity 24 hours (or 7 days) after graduation divided by liquidity 1 hour after graduation. The page shows the median per launchpad and day.
What is volume decay?
The rolling 24-hour volume 7 days after graduation divided by the rolling 24-hour volume 24 hours after graduation. Both are complete 24-hour windows after graduation.
Why is a 0.00 median possible?
Many graduated tokens have no trades a week later. When more than half of a cohort has zero 7-day volume, the median ratio is zero.
