What is USD1? The dollar stablecoin from World Liberty Financial

USD1 is a dollar stablecoin from World Liberty Financial, the crypto firm co-founded by Donald Trump and his three sons. Each token is meant to be worth $1. It launched in March 2025. Cash and short-term US Treasuries back it, held by the custodian BitGo.

The supply is real. About $4.28 billion of USD1 was in circulation on 10 October 2026, according to DefiLlama, spread mainly across the Ethereum, Solana and BNB networks. That makes it one of the larger dollar stablecoins, though USDT and USDC remain many times its size.

Who is behind USD1

World Liberty Financial debuted in October 2024. Its co-founders include President Donald Trump and his three sons, which is why the project draws far more attention than its size alone would earn. Zach Witkoff, the company's chief executive and a co-founder, has been the public face of its deals.

One point trips people up. The firm also sells a governance token called WLFI, and USD1 is a separate thing. One is a stablecoin meant to track the dollar. The other trades like any speculative crypto token. That difference, a stablecoin versus everything else, sits at the heart of the question over whether XRP counts as a stablecoin.

How USD1 is supposed to stay worth a dollar

The idea behind any dollar stablecoin is simple. For every token in circulation, the issuer is supposed to hold $1, or something close to it, in reserve. When demand rises, approved partners hand over dollars and receive new tokens. When they want out, they return tokens and get dollars back. That minting and redemption is what pins the market price near a dollar. If USD1 slips below $1, a trader can buy it cheap and redeem it for the full amount, which pushes the price back up.

In practice, USD1 works the same way. The catch is that direct minting and redemption are open to approved institutions, not to someone buying $100 of it on an exchange. Most holders rely on the open market, and on trust that the reserves are really there, to keep the peg honest.

What backs USD1

USD1 is meant to be fully backed. World Liberty Financial says every token is covered by short-term US government Treasuries, US dollar deposits and other cash equivalents. The reserves sit with BitGo, a regulated custodian that handles issuance, custody and redemption. BitGo publishes a reserve report each month. The most recent one listed on its page covers August 2026.

Here is the part that matters. Those monthly reports are attestations, not full audits. BitGo's page says an independent accounting firm examines management's own assertion about how many USD1 tokens can be redeemed and the assets set aside for them, using the 2025 AICPA criteria for asset-backed fiat-pegged tokens. The firm is not named there. No dollar figures either. Audits dig deeper. For a token holding billions, that gap is worth knowing.

Rules now sit behind that promise. The GENIUS Act, the federal stablecoin law President Donald Trump signed on 18 July 2025, requires dollar stablecoins to hold $1 of safe reserves, such as cash and short-term Treasuries, for every token in issue. It also tells issuers to report their reserves regularly. Full annual audited financial statements are required only for the biggest issuers, those with more than $50 billion in tokens outstanding. USD1, near $4.28 billion, sits well below that line, so its monthly attestations fit what the law asks of a stablecoin its size.

How people actually use USD1

Most of USD1's growth has come from big, arranged deals rather than retail demand. In 2025, the Abu Dhabi investment firm MGX used USD1 in connection with a $2 billion investment in Binance, the world's largest crypto exchange by trading volume. That single deal put the young stablecoin on the map.

Binance pushed it further. On 11 December 2025 the exchange said it would add USD1 trading pairs for tokens such as BNB, Ether and Solana across some of its busiest spot markets. It also said it would convert the collateral behind its Binance-Peg BUSD token into USD1 at a one-to-one rate within the week.

Witkoff called the move "an important moment in WLFI's effort to make digital US dollar stablecoins." The stablecoin trades on several exchanges now, and buying or selling it looks much like trading any other token.

By 10 October 2026, USD1's roughly $4.28 billion in supply sat mostly on three networks, with about $1.5 billion on Ethereum, $1.4 billion on Solana and $1.3 billion on the BNB Chain, according to DefiLlama. The rest was scattered across smaller chains.

Has USD1 held its peg?

Mostly, yes. The one notable wobble came on 23 February 2026, when USD1 slipped to about $0.994, roughly 0.6% below its dollar peg, according to CoinGecko. It climbed back toward $1 the same day.

World Liberty Financial blamed a coordinated attack. In a post on X, the team said several co-founders' accounts had been hacked, that paid influencers spread doubt, and that large short positions were opened against its WLFI governance token. The firm said its redemption system, which lets approved holders swap tokens for dollars one for one, kept the peg intact, and that the attack "didn't work." No outside party has confirmed that account. The price data is the only independent record, and it shows a brief dip, not a collapse.

The questions around USD1

A stablecoin tied to a sitting president is new. Because Trump and his sons are among World Liberty Financial's co-founders, the project has drawn criticism from government ethics experts over possible conflicts of interest, as The Block and other outlets have reported. Supporters call it an ordinary dollar stablecoin. Critics say a president should not profit from one.

There are plainer concerns too. Ordinary users do not redeem USD1 with the issuer directly. They buy and sell it on exchanges, while minting and direct redemption run through approved institutional channels. And its monthly reserve disclosures stop short of the detail that larger issuers now publish, the kind of reserve rules Circle has argued over with EU regulators.

Risks to weigh with USD1

No stablecoin is risk-free, and USD1 carries the usual risks plus a few of its own. A peg can slip if reserves fall short or a custodian runs into trouble. USD1 leans on one custodian, BitGo, which concentrates that risk. Its reporting is an attestation, so holders trust a snapshot rather than a deep audit. Its close link to a political family means headlines, not just markets, can swing sentiment.

None of this is a recommendation. The takeaway is simpler. Read the monthly reserve reports, understand who stands behind the token, and remember that a stablecoin is only as stable as the assets behind it.
