What it does

A new token's launch can make one first buy per pool before trading opens, at the launch price, delivered to the creator. It pays every fee a buy pays. The creator may hold at most 5% of supply when the launch finalizes, and the launch liquidity stays until the dev-buy lock ends.

How it works on reel

LaunchDevBuy(quote_in, min_out, lock_secs): new tokens only, once per pool, before LaunchFinalize. On a guarded pool it needs snipe_tax > 0 and snipe_cap ≥ quote_in (DevBuyRefused). Finalize checks escrow_left + dev_bought ≤ 5% of supply (RetainedAboveCap), and principal_lock_until = max(guard end, open + dev lock, open + lock end).

Worked example

A 1 SOL dev buy on the SOL pool with a 7-day lock pays the base fee, Snipe tax, LP Rewards and burn like any buy; LP parts land in the creator's own launch position, and its liquidity can't leave for 7 days.
