Data Types

• bigint: Large integer values for token amounts

• string: Text values for addresses and identifiers

• number: Numeric values for percentages and timestamps

• PreciseDecimal: High-precision decimal representation for UI display

• DecoderType: Enum indicating the decoder type (RAYDIUM_CPMM)

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.
