What is USDD?
About USDD
USDD (Decentralized USD) is a stablecoin launched in May 2022 by the TRON DAO Reserve in the TRON ecosystem founded by Justin Sun. USDD targets a 1:1 peg to the US dollar. It originally launched as an algorithmic stablecoin using a TRX mint-and-burn mechanism similar to Terra's UST, but after the Terra collapse in May 2022 and USDD's own depeg to about $0.97 in June 2022, the TRON DAO Reserve added collateral and moved the protocol toward an over-collateralized model. USDD 2.0 launched on TRON in January 2025 with an over-collateralized design and a staking yield subsidized by TRON DAO, and it was deployed on Ethereum on September 8, 2025, according to Messari and DropsTab.
USDD supply and backing
USDD does not have a fixed maximum supply. New USDD is minted when demand increases and burned when holders redeem, with supply adjusting to maintain the dollar peg. The backing model relies on crypto assets and stablecoins held by the TRON DAO Reserve rather than on cash reserves or US Treasuries.
Supply — approximately 1.58 billion USDD as of October 2026, according to CoinGecko
Collateral — a basket of crypto assets and stablecoins, including TRX, sTRX, BTC, USDT, and USDC, held by the TRON DAO Reserve; the reserve composition and collateral ratio are published by TRON DAO and change over time
Peg Stability Module (PSM) — enables 1:1 swaps between USDD and USDT or USDC, allowing arbitrageurs to correct peg deviations
sUSDD — staked USDD earns a variable yield; the 20% APY announced for the USDD 2.0 launch in January 2025 was fully subsidized by TRON DAO, and current yields can differ
Chains — natively issued as TRC-20 on TRON; deployed on Ethereum since September 8, 2025; also available on BNB Chain
What determines USDD's peg stability
USDD's peg relies on layers of defense. The PSM provides the first line: any time USDD trades below $1, arbitrageurs can swap USDD for USDT or USDC at par through the module and sell for profit, which pushes the price back to $1. Over-collateralization provides the second line: reserve assets are meant to exceed the USDD in circulation, which absorbs a decline in TRX or BTC before the peg is threatened. Reserve rebalancing by the TRON DAO Reserve provides the third line: the published composition has shifted over time from TRX-heavy toward stablecoins, which reduces volatility exposure.
USDD's history includes depeg events (June 2022 and later in 2022) that tested earlier versions of the stability mechanism. The reserve is managed by TRON DAO Reserve, so holders depend on its published reserve data and management, and the collateral mix still includes TRX and other volatile assets.

Frequently Asked Questions About USDD (USDD)
The TRON DAO Reserve manages USDD's reserve in the TRON ecosystem founded by Justin Sun. USDD is backed by a basket of crypto assets, including TRX, sTRX, BTC, USDT, and USDC; the collateral ratio and reserve composition are published by the TRON DAO Reserve.
Yes. It launched in May 2022 with a TRX mint-and-burn mechanism similar to Terra's UST. After Terra's collapse in May 2022 and USDD's own depeg to $0.97 in June 2022, the protocol moved to an over-collateralized model.
USDD 2.0 launched on TRON in January 2025 with an over-collateralized design, a Peg Stability Module for 1:1 swaps against USDT or USDC, and a staking yield subsidized by TRON DAO. It was deployed on Ethereum on September 8, 2025.
If USDD trades below $1, arbitrageurs swap USDD for USDT or USDC at par through the module and sell the stablecoin for a profit. The buying pressure pushes USDD back toward $1.
It means the reserve assets are meant to be worth more than the USDD in circulation. The extra buffer absorbs a sharp fall in TRX or BTC before the peg is threatened, but it does not remove the risk. Check the collateral ratio published by the TRON DAO Reserve for the current figure.
In 2022 the reserve was TRX-heavy. Since then the TRON DAO Reserve has shifted toward stablecoins such as USDT and USDC while still holding TRX, sTRX, and BTC. The current composition is published by the TRON DAO Reserve.
The TRON DAO Reserve manages the reserve assets backing USDD. Holders rely on its published reserve data and on the stability mechanisms, which makes reserve transparency a key point to check.
sUSDD is staked USDD that earns a variable yield. TRON DAO announced a 20% APY, fully subsidized by TRON DAO, for the USDD 2.0 launch in January 2025; later rates can differ. Treat any advertised yield as variable and not guaranteed.
USDD is natively issued as TRC-20 on TRON, was deployed on Ethereum on September 8, 2025, and is also available on BNB Chain. Choose the network the swap offer states.
Yes. USDD fell to about $0.97 in June 2022, and a later depeg in 2022 is also reported. CoinGecko listed USDD at about $0.999 in October 2026. A stable price today does not remove depeg risk.
Open swapzone.io/exchange/usdd, enter the amount, and compare offers. Choose TRON, Ethereum, or BNB Chain, paste the matching address, send USDD to the deposit address, and track the order. No MEMO is needed.
USDD stands for Decentralized USD. It is a stablecoin issued by the TRON DAO Reserve, designed to maintain a $1.00 peg to the US dollar. Unlike fiat-backed stablecoins (USDT, USDC), USDD maintains its peg through an over-collateralization mechanism backed by TRX (TRON's native token) and other crypto assets held in the TRON DAO Reserve. USDD launched on the TRON blockchain in May 2022 and is also available on Ethereum and BNB Smart Chain. Total USDD supply was approximately 1.74 billion as of October 2026, according to CoinGecko.
USDT is issued by Tether Limited, backed by off-chain cash and Treasury bills held in custody, with no on-chain collateral. USDD is issued by the TRON DAO Reserve, backed by on-chain crypto collateral (primarily TRX and Bitcoin) held in smart contracts. This means USDD carries algorithmic and collateral risks similar to other over-collateralized crypto-backed stablecoins, while USDT carries custodial and counterparty risk from Tether's reserve management. USDD also experienced a de-pegging event in 2022 during market stress, which is a relevant context for evaluating the peg mechanism's resilience.
USDD can be swapped for any cryptocurrency supported by Swapzone's exchange partners, including BTC, ETH, XMR, USDT, and hundreds of other assets. Select USDD as the sending asset, choose the receiving asset, and compare live offers. USDD on TRON (TRC-20) requires TRX for gas. USDD on Ethereum (ERC-20) requires ETH. USDD on BNB Smart Chain (BEP-20) requires BNB. Always match the network to the partner's deposit requirements.
USDD has maintained approximate dollar parity since recovering from a 2022 de-pegging event, but it carries structural risks different from fiat-backed stablecoins. As an over-collateralized crypto-backed stablecoin, USDD's peg stability depends on the TRX collateral value remaining above the required ratio. If TRX drops sharply, the TRON DAO Reserve must add collateral or liquidate positions to maintain the peg. These mechanics are transparent and on-chain but introduce volatility risk that cash-backed stablecoins do not carry. All stablecoins carry some form of reserve or protocol risk.

The site experience was great. But choose your exchange platform wisely.
The site experience was great, as on previous occasions. I made a mistake, however, by choosing a different exchange provider, EasyBit, and the result was much worse than I was given to expect. Changelly was the best before and I will choose that option in future.

Unstaking ONT without having ONG
My problem was to unstake ONT in my wallet which I administrate with the Exodus software without having ONG for gas fee. The swapping function in Exodus is no longer available and they will suspend the support of Ontology soon. By means of the fantastic swapzone-node I was able now to swap TRX into ONG and receive the ONG directly at my adress of ONT-asset. So I was able to start the unstaking procedure. And one more advantage: The swapping of TRX to ONG and sending it to the ONG-adress was quite simple for beginners like me: I'm used to krypto ledger, but this was my first experience with swapping-nodes.
Great service with great support!
not so long ago I was looking for a service that allows you to exchange cryptocurrency quickly and effortlessly. today, when I once again decided to exchange usdt to eth - I wrote the wrong wallet, namely the wallet from the last exchange (incorrectly indicated the amount), to which the usdt should have been sent. after contacting support, I was almost immediately refunded, which I am very happy about! I recommend using this service! 100/100
Very competitive pricing and fast support - great!
I used swapzone.io over 10 times recently and never had an issue. In fact, I had once a visual bug of the swap interface when the funds were sent but it was correct again the second I started a chat with support. In less than 2 minutes I had a very friendly employee talking to me. Very competitive pricing and fast support.
everything was fine
i successfully exchanged currencies. it took just a couple of minutes
everything is in one place
I'm new to cryptocurrency, and I'm always frightened by the choice of services. I really liked that everything is in one place here, and you can choose from familiar names and compare prices between them. The exchange took place fast and without any problems.
I tried swapping nearly $1000 worth of
I tried swapping nearly $1000 worth of bitcoin with the cake app four different times this evening and it wouldn’t work. Thankfully, their support was able to give me my money back quick and I was able to come here and I found an even better rate than what I got with cake. This will probably be my new go to crypto swapping platform. 100 out of 10 recommend and you can order with confidence :-)

Honestly in this industry it’s hard to fbb in f great costed service but Liam at swapzone handled an issue for me and solved it and no bs just helping me out. Thank you. My first time using swap zone to swap crypto was great and I’ll be back now .
Read this carefully
Works every time and helps to find the best deal. Is what I would say if I wanted to leave regular review. What I am going to say is that this service is unmatched in crypto sphere how they handle their business. I sent crypto to a swap in 2 transactions instead of one(my mistake) and when I opened the chat and explained my issue they contacted the parter doing the swap and gave me option to get a refund or continue with the swap at the current rate. Others would just keep it of tell you its lost. So not only they help you find the swaps but they act as a liaison if there are issues.
perfect service
perfect service. great support. I can wholeheartedly recommend this service. The support is fast, helpful, and solution-oriented. You won't find that with other Exchange services. A++++ thanks
