# Core Features

USDD stands out as a next-generation stablecoin built on principles of decentralization, transparency, and user empowerment. Below are the core features that define its functionality and value:

1. **Decentralized Governance**\
   USDD is governed by a transparent, community-driven process through decentralized proposals and on-chain voting mechanisms.
2. **Transparency and Auditability**\
   All collateral and transactions supporting USDD are fully auditable and recorded on the blockchain. This open-source approach guarantees users can verify the system's integrity in real-time, fostering trust and security.
3. **Enhanced Security**\
   Over-collateralized reserves help support USDD’s stability and provide a buffer against market fluctuations. Decentralized governance mechanisms further safeguard the stability and security of the ecosystem.
4. **Seamless DeFi Integration**\
   USDD integrates effortlessly into the broader DeFi ecosystem, enabling use cases like lending, borrowing, staking, and trading. This interoperability makes it a versatile tool for both individual users and institutions.
5. **Freeze-Free Transactions**\
   Once USDD is held in a self-custodial wallet on-chain, no centralized authority can directly freeze the USDD token itself.
6. **Multichain**\
   The current USDD application supports **TRON, Ethereum, and BNB Chain**. Token transfers and bridge or migration routes are distinct from protocol features such as Vaults, PSM, and Savings; availability, collateral types, and parameters depend on the selected network. Check the application and [Contract Addresses](https://docs.usdd.io/introduction/collateral-asset-contract-addresses) for that network before use. References to USDDOLD or historical BTTC migration routes do not establish current USDD protocol support on BTTC.

These core features make USDD a robust and adaptable stablecoin, designed to empower its users while maintaining the highest standards of stability, security, and decentralization.
