Method

The window

Each pool is measured over 10 slots, s_open through s_open + 9.

• Slot activation: s_open = max(creation slot, activation point).
• Timestamp activation: s_open is the slot of the first swap at or after the activation time.

SNP10

SNP10 = Σ base tokens bought by non-creator payers in the window ÷ swap_base_amount, where swap_base_amount is the sellable supply on the curve, read from the pool’s PoolConfig.

• The payer of a buy is the payer account of the DBC swap instruction that emitted the event. EvtSwap2 carries no payer field, so the emitting instruction is located by its stack height.
• A buy whose payer cannot be paired with an instruction is counted as non-creator.
• Windows are finalized from confirmed signatures only; a window with unconfirmable signatures is marked partial.

Ranking

• A config is ranked by its median SNP10 once it has at least 20 complete windows from at least 5 distinct creators.
• Each median carries a 90% bootstrap confidence interval with a fixed seed, so reruns agree.
• Configs whose intervals overlap share a rank, shown as =3.

Limits

A creator who funds fresh wallets and buys through them looks like an outsider. SNP10 counts those wallets as non-creator, so it measures supply taken by anyone other than the creator’s own signing wallet, not proven third-party snipers.

Nothing is shown from before the indexer’s capture start slot; history accumulates from that slot forward.
