Pons graduation census
Nobody has added liquidity to any of these pools.
Two log queries give the funnel: how many tokens Pons launched in the window, and how many reached a Uniswap v4 pool. The graduated ones are then read one at a time, because what matters is not in the launch record. Each of those pools reports a fee of zero and is not free, and in each of them the locked full-range position the launchpad minted at graduation is still the entire active book. That share is measured below, per pool, against the pool’s own liquidity.
Counting launches and graduations from chain logs, then reading each graduated pool.
