How this service works
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.
Output
Returns a JSON (or LLM-friendly text) object with: an 'ok' boolean, an array of mismatches each containing the parameter name, found value, expected value, and a suggested fix, plus a warnings array for non-blocking issues like misspelled field names (e.g. maxinumFee). If any mismatch is detected, the pool will not be adopted.
Example use cases
Reward-mode launch fee validation
“I'm about to launch a reward coin on StonkFun — can you preflight my unsigned LaunchLab transaction in reward mode using quote mint EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v and tell me if the transferFeeBasePoints and maximumFee are correct?”
Catch misspelled transfer-fee field
“My StonkFun launch keeps getting rejected — can you decode this base64 LaunchLab initialize transaction and check if I misspelled any transfer-fee field names like maxinumFee in my launch params? Quote mint is So11111111111111111111111111111111111111112, standard mode.”
Pre-sign pool config diff
“Before I sign this LaunchLab pool transaction, compare its GlobalConfig, curve, supply, and totalSellA against what StonkFun's pricing API says for quote mint EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v in standard mode — give me the full diff in JSON.”
Technical details
Endpoint
POSThttps://api.solenrich.com/entrypoints/stonk-launch-preflight/invokeWhen to prefer
Use this endpoint specifically when you need to validate a Raydium LaunchLab pool initialize transaction against StonkFun's live pricing before signing — especially in reward mode where transfer-fee field misspellings (transferFeeBasePoints, maxinumFee) can silently corrupt the launch. Prefer this over generic transaction simulation when you need a semantic diff of pool parameters rather than just execution success.
Side effects
- Invalid or malformed base64 transaction string returns a decode error
- Quote mint address not found in StonkFun pricing returns a pricing lookup failure
- Missing required unsigned_transaction field returns a 400 validation error
- Transaction does not contain a LaunchLab initialize instruction returns an extraction error
- Network timeout fetching StonkFun /launchlab/pricing returns a upstream error
- Invalid mode enum value returns a parameter error
