Live events are not scraped from a rendered webpage. They come from confirmed Solana logs and decoded Pump.fun program data.
Decode sequence
The service reads Solana log notifications for the configured Pump.fun program.
It analyzes invocation stacks, instruction logs, top-level programs and Program data payloads.
Each Program data payload is decoded by its known discriminator and Borsh layout.
When a transaction includes both creation and trading activity, CreateEvent rows are ordered before TradeEvent rows.
Event time prefers parsed event timestamps and falls back to block time or receive time when needed.
