You open the account and the DAI line is gone. In its place sits USDS, for exactly the same number of tokens, and nothing ever asked you to confirm anything. That is not a display glitch and nobody touched your balance in the night.

The dates explain it. Binance's English announcement says all existing DAI spot trading pairs were removed at 2026-04-07 03:00 (UTC), that DAI deposits and withdrawals were suspended half an hour later at 03:30, and that balances were distributed at a ratio of 1 DAI = 1 USDS. Trading in BTC/USDS, ETH/USDS and USDS/USDT opened at 2026-04-09 08:00 (UTC). Times and wording follow the announcements as published; we checked them in September 2026.

What makes this confusing is that two different things happened at once: the issuer upgraded DAI into USDS, and an exchange swapped the balance in your account for you. They differ in who acted, whether it can be undone, and what is left open afterwards. If you want the mechanics of how any of these tokens hold a dollar in the first place, that's in what a stablecoin actually is; this page is only about the rename.

What the announcements actually scheduled

Here are the lines that touch an ordinary holder, in order. All times are UTC, as the English announcements give them.

WhenWhat the announcement says
2026-03-31 08:00Deposits and withdrawals over the POL (Polygon POS) network suspended
2026-04-07 03:00All existing DAI spot trading pairs removed
2026-04-07 03:30DAI deposits and withdrawals suspended
Distribution"The distribution was conducted at a ratio of 1 DAI = 1 USDS."
2026-04-09 08:00Trading opens for BTC/USDS, ETH/USDS and USDS/USDT

Note the first row. The Polygon network closed a week before everything else, which is the kind of detail that only matters if you happened to be moving tokens on that chain that week, and the kind that gets lost when a rename is summarised in one sentence.

The same announcement covers other product lines as well, each on its own schedule. Those sit outside what this site covers, so read the announcement itself rather than trusting any second-hand figure, including ours.

On the protocol side, DAI was not retired

Start with the issuer, because that decides whether the old tokens are worth anything at all.

Sky's developer documentation has a short section on the converter between the two tokens, and it is unusually plain about it. The converter moves DAI into USDS at a fixed ratio of 1:1 and back the other way. No fees are assessed. And then a sentence you don't often see in token documentation: "Fees cannot be enabled on this route in the future."

So DAI was not declared void, and nothing forced it out of existence. Upgrade here means the issuer shipped a new token and moved its attention to it — not that the old one stopped being redeemable for the new one.

USDS comes with a savings rate entry point. Sky's own site describes it as a variable protocol rate funded from aggregate protocol surplus that can change over time, and says in the same breath that Sky.money does not control, set or guarantee it. We don't write yield tutorials here, so treat the number on the day as whatever the official page says on the day.

The exchange side: a swap done for you, and what is left for old DAI

The protocol offers a route you may take or ignore. The exchange did something else: it converted everyone's balance on a published schedule, without asking and without anything for you to click. Both got reported in the same week, and the result is a vague impression that DAI disappeared.

If your tokens simply sat on the exchange, this was the easy version of the event. No deadline to catch, and the token count came out the same. You paid no network fee for any of it. The part worth noticing is that open orders were cancelled automatically when the pairs came out.

When an announcement carries phrases like "will remove all existing DAI spot trading pairs", cancelling your own orders first is usually easier than letting the system do it. Not because the system gets it wrong. It is that deciding what to do after the cancellation is easier while you are watching the market, instead of finding a flat balance and a different market the next morning.

Then there is the group that gets skipped in most coverage: the tokens were never on the exchange, so no swap reached them. The completion announcement covers this case, but only if you read three of its sentences together:

Read together, the exchange route is one-way and its closing date is not yours to choose. The other route is the converter described above: two-way, no fee, at the cost of doing it yourself on-chain and carrying the usual network fee and wrong-address risk.

Which one suits you depends on where the tokens are, how much is involved and whether you use an on-chain wallet at all. We're not picking for you, and we wouldn't rush the decision on account of the rename alone.

Whether the new token is still the decentralized kind

This is the question people actually type into a search box, and the one most pages answer with a shrug. We'll stay with what the issuer's own documents say.

Sky's developer documentation describes USDS as an ERC-20 token with added support for permit functionality and EIP-1271 smart contract signature validation, and states that it "is designed with upgradeability in mind, using the UUPS pattern and ERC-1967 proxy storage standards". Upgradeable proxy is the load-bearing phrase: it means a path exists for the contract's logic to be changed after deployment, rather than being fixed the moment it goes live.

Sky's legal risk documentation is blunter still. On parameters: those "including interest rates, collateral requirements, fees, and reward allocations — can change at any time through processes in which Skybase International does not participate". On code: bugs, defects or exploits "even after auditing — can lead to loss, freezing, or theft of assets". And on the peg itself: a stablecoin such as USDS "aims to hold a stable value but may not do so at all times".

One thing we will not do here is repeat a claim we couldn't verify. Several third-party write-ups say USDS carries a freeze or blacklist capability that DAI lacked. We read Sky's developer page for USDS and its user-risk document line by line, and neither contains such a clause; the only mention of freezing sits inside the sentence about code exploits quoted above. So we're not stating it as fact and we're not treating a review site as the authority on an issuer's contract. If it matters to your decision, the place to settle it is the issuer's contract documentation and governance records.

Which brings the question back to definitions. If decentralized means "nobody can alter the contract once it ships", the documentation already tells you USDS was designed the other way. If it means "no single company stands between you and redemption", then you assess it the same way you'd assess any newer token: read the terms, find out who may redeem, find out who can change the parameters. We ran that routine across the recent arrivals in USDe, PYUSD and the newer stablecoins.

Whether to keep holding is not something this page decides. The name changed and the balance didn't. The redemption questions sit exactly where they were, and they are easier to weigh on their own.

Common questions

I did nothing and my DAI balance turned into USDS. Is that expected?

Per the announcements, the exchange carried out the swap for every holder at a ratio of 1 DAI = 1 USDS, with no confirmation needed from you. The distribution announcement states it was conducted at that ratio, which is why the ticker changed and the number did not. Times and wording follow the announcements as published; checked September 2026.

What can I still do with old DAI sitting in my own wallet?

Two routes. The issuer's converter, which Sky's developer documentation describes as converting DAI to USDS at a fixed 1:1 ratio and back again, with no fees assessed and no ability to enable fees on that route later. Or deposit the old tokens to the exchange and use Convert to swap them 1:1, keeping in mind that the announcement says deposits and conversion of old DAI may stop without prior notice, and that withdrawals of old DAI are no longer supported.

Is USDS still the decentralized stablecoin DAI was?

It depends on which part of decentralization you mean. Sky's developer documentation states USDS is designed with upgradeability in mind, using the UUPS pattern and ERC-1967 proxy storage standards, and Sky's legal risk page states that parameters including interest rates, collateral requirements, fees and reward allocations can change at any time. Those are facts from the issuer's own documents; whether they meet your standard is not a call we make for you.

Primary sources and check date

Checked 21 September 2026; any of these may have changed since:

Two further citations are not linked separately: Sky's own site for the wording that the savings rate is a variable protocol rate funded from surplus and is not controlled, set or guaranteed, and Sky's legal user-risk document for the passages on parameter changes, code exploits and the peg. Both checked on the same date.
