#usdd以稳见信 1. USDD Overview: Evolution from 1.0 to 2.0

USDD is a decentralized stablecoin on the TRON network, pegged 1:1 to the US dollar, ensuring stability through an over-collateralization mechanism. Unlike centralized stablecoins (such as USDT), the USDD 2.0 version introduces a 'freeze-free' design, independent audits, and on-chain data transparency to avoid risks associated with control by a single entity.

Core Mechanism: Collateral assets include TRX, BTC, ETH, etc., with a collateralization ratio maintained above 120%. sUSDD is its interest-bearing token, allowing users to earn approximately 12% base APY just by holding it.

Ecological Positioning: Integrates TRON, Ethereum, and BNB Chain, supporting DeFi protocols such as JustLend DAO, Uniswap, and Aave.

USDD emphasizes 'trust but verify': all collateral data is publicly available on-chain, allowing users to monitor reserve changes in real-time. This stands out in the stablecoin market, avoiding the blind trust model of 'Trust me, bro'.
