SPL Token Operations

Name: tessl/pypi-solana
Author: tessl

Comprehensive SPL Token program interface for token creation, account management, transfers, and advanced token operations. The library supports both the standard SPL Token program and the newer Token-2022 program with enhanced features.

Capabilities

Token Client Initialization

Create token instances for interacting with existing tokens or initialize new tokens with mint authorities and program configurations.
