Understand a transfer from the inside: address, network, ETH fee and why there's no undo. Without sending anything.
It starts with 0x and has 42 characters. Copy and paste it, never type it. Before sending, check the start and the end.
Your address is the same on Base, Ethereum and Arbitrum. The balance isn't: the money only shows up on the network it was sent on.
Receiving costs you nothing. The sender pays a network fee in ETH, even when sending USDC. On Base, it's usually cents.
No refund and no support team can reverse it. That's why, to a new address, you send a small amount first and see if it arrives.
Scammers make an address show up in your history with the same start and end as your contact's. Tap to compare the middle.
Always copy from the source, never from your history.
No need to do it now. Keep this checklist.
