FAQ
Everything about USD1.
What is USD1 backed by?
U.S. cash, government money market funds, and short-term U.S. Treasury securities. Reserves are held in custody by BitGo Trust Company, a regulated South Dakota custodian; Treasury assets are managed by Fidelity Investments.
Why accept it instead of USDT or USDC?
USD1 plays the same role as other major stablecoins but also offers a clean U.S. regulatory framework and rapid institutional adoption. Businesses serving U.S. or U.S.-aligned clients increasingly request it as a settlement option.
How fast are transactions?
Confirmation depends on the network: under a second on Solana, a few seconds on BNB Chain or Tron, and slightly longer on Ethereum. All settled without waiting for banking hours.
Can I withdraw to a bank account?
Yes. USD1 can be redeemed for fiat through compliant off-ramps or held as a digital dollar for ongoing operations. Within 0xProcessing, you can also exchange it for other supported assets directly from your dashboard.
What networks does 0xProcessing support for USD1?
USD1 transactions are processed on Ethereum, BNB Chain, Tron, and Solana. We add new networks as the ecosystem expands.
What other cryptocurrencies can I accept?
0xProcessing supports 100+ cryptocurrencies across 18 blockchains – BTC, ETH, USDT, USDC, SOL, BNB, and many more.
