How to buy USDAI, step by step

Choose an exchange that lists USDAI
USDAI trades on 4 of the exchanges we track. The most active is Fluid (Arbitrum), with $1.65M in 24-hour USDAI volume; Uniswap V4 (Arbitrum) and Aerodrome Slipstream 2 are the next options.
Check that the exchange is licensed or allowed to operate where you live — the same exchange can offer different coins in different countries.
Create an account and verify your identity
Centralized exchanges ask for an email, a password and, before you can deposit money, identity verification (KYC) with a photo ID. Turn on two-factor authentication with an authenticator app, not SMS, as soon as the account is open.
Deposit money and buy 0XAF88…5831
None of the USDAI markets we track are paired with a national currency, so it's a two-step purchase. 100% of USDAI trading is against 0XAF88…5831, so buy 0XAF88…5831 first with a bank transfer or card.
Buy USDAI
Open the USDAI/0XAF88…5831 market and enter how much you want to spend. A market order fills immediately at the best available price; a limit order waits until the price reaches the level you set. The gap between buy and sell prices is around 0.62% on the main markets, so a limit order can save you money on larger buys.
Decide where to keep it
You can leave USDAI on the exchange, which is simplest, or withdraw it to a wallet you control. Before withdrawing, check that your wallet supports USDAI on the same network the exchange sends on — funds sent over the wrong network can be lost.
