# Pumpfun Smart Contract - TOKEN2022 Integration
## Overview
The Pump.fun Smart Contract integrates with TOKEN2022, the latest upgrade to the SPL token program on Solana. TOKEN2022 adds new features like programmatic governance, custom fees, and tax handling, making it ideal for projects that need flexible token mechanics and DeFi capabilities.
## Why TOKEN2022?
TOKEN2022 improves on the original SPL token standard, adding more functionality and flexibility for tokenized assets. Key benefits include:
- **Enhanced Tokenomics** – Support for built-in tax mechanisms, royalties, and custom transaction fees.
- **Improved Governance** – On-chain governance capabilities allow seamless protocol upgrades and community-driven decision-making.
- **Expanded Flexibility** – Developers can create tokens with advanced behavior, optimizing interactions within decentralized applications.
