Stonk Launch Preflight Invoke

by SolEnrich in Onchain & crypto

x402 APIPassing, checked 3 h ago

Decodes the Raydium LaunchLab initialize in your unsigned transaction and diffs it against StonkFun's /launchlab/pricing for that quote + mode: GlobalConfig, platform id, curve, supply, totalSellA, raise, 6-decimal Token-2022 base mint, quote token program, curve-rule account last, and the reward-mode transfer fee (catches the transferFeeBasePoints / maxinumFee spelling). Returns ok, mismatches with fixes, warnings. A mismatched pool is never adopted.
