Class Base class for every exception the Crossmint SDK throws. 
class CrossmintException implements Exception
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.

​
Constructors

​
CrossmintException

const CrossmintException(
  this.message, {
  this.code = CrossmintErrorCode.unknown,
  this.cause,
})
Creates a generic CrossmintException. Prefer throwing a subclass scoped to the failure domain (auth / wallet / signer / …).

​
Properties

​
message

final String message
Human-readable message suitable for logs. Not localized — do not show this directly to end users.

​
code

final CrossmintErrorCode code
A machine-readable error code for programmatic switch/case handling.

​
cause

final Object? cause
The underlying cause — typically a lower-level exception or an API response payload. Inspect this for extra detail when diagnosing errors.
