CrossmintException class

Base class for every exception the Crossmint SDK throws.

Every subclass carries a code (CrossmintErrorCode) so consumer code can switch on error categories instead of string-matching on message. The optional cause preserves the original error / payload that triggered this exception — useful for logging and programmatic handling.

Implemented types

• Exception

Constructors

CrossmintException(String message, {CrossmintErrorCode code = CrossmintErrorCode.unknown, Object? cause})

Creates a generic CrossmintException. Prefer throwing a subclass scoped to the failure domain (auth / wallet / signer / …).

const

Properties

cause → Object?
