《A Brief Understanding of the Differences Between USDD, USDT, and USDC Stablecoins》
Many people treat stablecoins as "cash".
But the truth is: USDC/USDT are more like bank deposits, while USDD is more like native DeFi cash. The difference isn't about "who is bigger", but rather: are you more afraid of volatility, or more afraid of a switch that can be turned off at any moment? (Let the bullets fly for a while; we'll clarify the logic.)
First, let's position the three brothers correctly:
USDC / USDT = centrally issued on-chain USD: strong compliance, strong liquidity, strong redemption mindset;
USDD = emphasizes a permissionless + anti-censorship narrative stable system: leaning towards DeFi logic. If you treat them as "the same thing", you are likely to fall into a trap at critical moments—because what you are buying is not the same kind of "risk structure".
Why do I say that USDD's advantages are often underestimated?
First, choice. The strength of USDC/USDT lies in compliance and risk control, but the cost is that the address may be restricted/frozen; the core narrative of USDD is exactly the opposite: closer to a "permissionless stablecoin". If you are doing cross-border payments, on-chain high-frequency strategies, or if you simply dislike "centralized switches", USDD offers you not profits but psychological safety margins.
Second, DeFi native structure. USDD emphasizes on-chain mechanisms more: collateralized minting (CDP) + stable exchange module (PSM) provides 1:1 exchange anchors and arbitrage channels. It is more like a composable stable system, rather than just "I give you an IOU".
Third, the TRON ecosystem experience feels like cash. Many people use TRC20 for reasons you understand: cheap, fast, usable everywhere for receiving and transferring. If your activity radius is within TRON (transfers/receiving/mining/lending/LP), the ecological smoothness of USDD will be more apparent—especially at high frequencies, the cost difference will be infinitely magnified.
Finally, to be honest (and a risk reminder):
The advantages of USDC/USDT are "strong redemption/strong compliance/strong liquidity";
The advantages of USDD are "permissionless/anti-freeze narrative/DeFi native/ecosystem experience".
But don’t use USDD to claim "most stable and safest" head-on—there is no perfect solution for stablecoins, only trade-offs.
Here comes the question: if you had to choose one, do you care more about "stability" or "not being switched off"? Share your usage scenarios in the comments. @USDD - Decentralized USD
