- Enter a USDC address in BASE and a way to reach you.
- Send CAT in Simon's Cat for exactly the amount stated in the order.
- Once the network confirms your transfer, USD Coin leaves for your address. The order page tracks every step.
Check this before sending CAT

- Copy the address whole, then compare the first and last characters after pasting.
- Coins go through an AML check: a flagged transfer can be held until the check is finished.
