# kitb create-tx metadata (#639)
Where: research-box /opt/sw/kitb.db, table cls (one row per v3 WETH pool, ~3,930 rows, last ~8 days of launches).
New columns: create_value_eth (REAL, ETH sent in the create tx), create_input_len (INT, calldata bytes). Existing: sender, to_, tx, kit, t, b.
Live: kitb.py (timer every 10 min) fills them for each new pool. Backfill of older rows runs 600 rows/run on the free public RPC (~70 min to finish all); check `count(create_value_eth)` vs `count(*)`.
Gaps: only v3 WETH pools in kitb's 8-day window; v4 Initialize-tx value and the 12 Sep v3hist backfill are ppdata #640.
Note: batched eth_getTransactionByHash of 20+ txs fails on the RPC (response size), so backfill is single calls.
Query: select kit, count(*), avg(create_value_eth>=12.5) from cls where create_value_eth is not null group by kit;
