Data Types

• bigint: Large integer values for token amounts and reserves

• string: Text values for addresses, names, symbols, and URIs

• number: Numeric values for other integer values

• boolean: True/false values for buy/sell direction

• PreciseDecimal: High-precision decimal representation for UI display

• DecoderType: Enum indicating the decoder type (BOOP_FUN)

Usage

The decoder automatically determines the event type and returns the appropriate structure. All monetary values are provided in both raw (bigint) and UI-formatted (PreciseDecimal) versions for flexibility in different use cases. The Boop Fun decoder handles token initialization and swapping mechanics with virtual reserve management and balance tracking.
