How the STRK ERC20 → USDC Polygon order runs
- Work out the amount in the calculator: orders start at 7,429.42 STRK ERC20.
- Enter a USDC address in Polygon and a way to reach you.
- Send STRK ERC20 in Ethereum (ERC20) 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 STRK ERC20
- The address network is Polygon. Sending through another network usually means losing the transfer.
- The transfer must not be smaller than 7,429.42 STRK ERC20.
- 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.
