If you sent USDC to the wrong address or network, what you can do depends on where the funds were sent and whether you control the receiving wallet.
If the transaction completed on the network you used, your USDC is on that network, you may just need to switch your wallet to view it.
Blockchain transactions can’t be reversed. If you sent USDC to the wrong address, Circle can’t recover the funds. If you know who controls the receiving wallet, contact them directly.
Switch your wallet to the network you used.
Open the transaction in a block explorer and confirm it shows Success/Complete.
Check whether your wallet supports USDC on that network.
