Sameca protocol

First buy

Optional seed buy is per book. On Robinhood Chain and BSC it can ride in the launch transaction. On Arc it cannot.

Robinhood Chain and BSC

Native coin → dollar stable → token, on the same DEX as the pool. The stable hop should use the deepest low-fee dollar pool; the token hop pays the Sameca take (1% + extra tax) on the curve, then on the hook after graduation.

Arc

Gas is USDC itself. There is no wrapped-native contract for a router to mint. The first buy is a second confirmation: approve the USDC ERC-20, then swap. The launch UI must show both steps. Relayed launches to Arc skip a bundled first buy.

Native USDC gas is 18 decimals. ERC-20 USDC is 6 decimals at 0x3600000000000000000000000000000000000000. They share one balance. Do not wrap. Do not mix the two scales in your head.
