USD1 is a U.S. dollar stablecoin launched in March 2025 under the brand of World Liberty Financial (WLFI), a crypto company backed by U.S. President Donald Trump's family. It is designed to trade at one dollar and be redeemable one-for-one.
The token itself is issued and redeemed by BitGo Bank & Trust, N.A., a national trust bank supervised by the U.S. Office of the Comptroller of the Currency. World Liberty owns the USD1 brand, while BitGo handles minting, redemptions, custody of the reserves and daily reconciliation.
In roughly a year and a half, USD1 has become one of the ten largest stablecoins, with around $4 billion in circulation as of October 2026, most of it on Solana, Ethereum and BNB Chain.
How USD1 is backed
USD1 is a fiat-backed stablecoin. According to BitGo's August 2026 reserve report, examined by KPMG, the roughly $4.2 billion of reserves sat in two buckets: about 73% in U.S. government money market funds and about 27% in cash held in bank deposit accounts, slightly more than the tokens outstanding.
BitGo publishes a monthly attestation under the AICPA criteria for fiat-pegged tokens, and World Liberty runs a proof-of-reserves dashboard. Only registered BitGo customers in good standing can mint and redeem directly; everyone else buys and sells USD1 on exchanges.
Where USD1 runs
As of October 2026, USD1 supply is split almost evenly across three networks: Solana (about 35%), Ethereum (about 33%) and BNB Chain (about 30%). Smaller amounts live on Aptos, Tron and a handful of newer chains.
Who uses USD1
USD1's growth has been driven by large trading venues more than by everyday payments. Abu Dhabi's MGX used USD1 to settle its $2 billion investment in Binance in 2025, and Binance has since listed multiple USD1 trading pairs and run holder reward campaigns. Exchanges including Bybit, Gate, MEXC and Aster DEX now support it, and single-day trading volume has topped $1.6 billion.
World Liberty is now pushing into payments: an AgentPay SDK for AI-agent transactions launched in March 2026, a planned remittance product called World Swap, and a Mesh partnership announced in October 2026 to let USD1 holders spend at Mesh's merchant network.
- Trading pairs and collateral on centralized and decentralized exchanges
- Large institutional settlements, such as the MGX investment in Binance
- DeFi lending and liquidity on Solana, Ethereum and BNB Chain
- Emerging merchant and AI-agent payments via World Liberty partners
What to watch
Political and governance risk is the defining issue. USD1's ties to the sitting U.S. president's family have drawn questions from lawmakers about conflicts of interest and foreign ownership links, and regulatory or political shifts could affect how institutions treat it.
Concentration is the second. Supply depends heavily on a few large holders and venues: in October 2026, USD1 shed more than $400 million, about 9% of its market cap, in two weeks of large redemptions on Ethereum and BNB Chain, including nearly $200 million from a single address. The peg held between $0.998 and $1.000 throughout, which is a good sign for the redemption process, but supply can swing quickly.
