Both phases preserve a constant product; their fee leg differs by launchpad.
Pons V2 curve
Invariant
k = virtual quote × virtual tokens
Buy output
Δtokens = Vtokens × Δquote ÷ (Vquote + Δquote)
Progress
sold tokens ÷ curve allocation
V4 migration seed
Seed
Tpool = Tswept × 4.2 ÷ (4.2 + 1.68)
Buy output
Δtokens = T × Δquote ÷ (quote reserve + Δquote)
Token-input sell output
Gross quote = Q × tokens sold ÷ (token reserve + tokens sold); net after fees
Target plan
bonding buy, then pool buy when target > curve allocation
Market cap is spot price × full token supply. This planning estimate excludes on-chain integer rounding, live dynamic fee config, priority fees and slippage.
