Imagine this scenario: In 2025, to seize market share, major NFT trading platforms are rapidly canceling royalty policies, and some even block contracts that enforce royalties at the frontend. Artists and project teams who rely on royalties collapse overnight, losing all passive income. The Web3 "rights confirmation" promise instantly turns into a bubble. Creators have no choice but to seek new paths unaffected by centralized platforms.

The turning point arrives: an on-chain payment model based on USDD 2.0 is becoming a lifeline for the copyright economy.

Why do royalties become ineffective? Simply put, they rely entirely on the "goodwill" of trading platforms. Just one word from the platform, and all income disappears.

USDD 2.0's approach is completely different—building a "direct economic pipeline" between creators and fans.

**Step 1: Programmable Subscription Streams**

Creators no longer rely on secondary market trades for small gains; instead, they issue "membership card NFTs." Holders establish a fund flow with the creator’s address via USDD smart contracts—such as automatically deducting 5 USDD each month. It sounds simple, but here’s the clever part: USDD transfers on Tron are ridiculously cheap, making high-frequency small payments economically feasible. Switch to Ethereum? Gas fees could eat up the entire subscription fee.

**Step 2: Income Yield Loop**

The USDD received by creators doesn’t just sit idle in their accounts. Smart contracts automatically bundle income into a Smart Allocator, participating in yield distribution. The money flows not only to creators but also continues to generate interest.

The core of this mechanism is: upgrading the relationship between creators and consumers from "transaction" to "collaboration," ensuring income is no longer bottlenecked by platforms but guaranteed by on-chain code. Once on the chain, no one can change it.
