What problem does it solve? Pump.fun's May 2026 V2 upgrade changed quote-mints from SOL to USDC, added new instruction discriminators and accounts, and altered event layouts, breaking downstream code in hard-to-diagnose ways. This Skill identifies which changes affect a given codebase and routes each symptom to the correct fix and reference document. ## Core Features & Use Cases - Impact Diagnosis: A decision table maps your code's behavior (event parsing, instruction building, quote-mint assumptions) to the specific V2 changes that affect it. - Symptom-to-Fix Lookup: Common failures like MissingAccount errors, mis-scaled amounts, and empty creator vaults are matched to their root causes and remedies. - Ordered Migration Plan: An eight-step migration sequence from bumping pump-sdk to regression-testing against V1/V2 fixtures. - Use Case: Your event decoder silently ignores new pump.fun launches after May 2026. Use this Skill to identify the hardcoded V1 discriminator as the cause and follow the linked reference to update your decoder tables. ## Quick Start Ask the assistant to diagnose why your pump.fun event parser stopped decoding new launches after the V2 USDC rollout and produce a migration plan.
