Why a crypto transfer cannot be reversed — and what to do instead
There is no chargeback on a blockchain. Here is why, what that changes about how you should send, and the habits that prevent the mistakes that cost people money.
A bank transfer can be recalled. A card payment can be charged back. A blockchain transfer cannot be either, and this is not a policy choice anyone can make an exception to — it is how the technology works.
A confirmed transaction has been written into a ledger that thousands of independent computers agree on. There is no authority with the power to edit it, which is the entire point of the design. The flip side is that a mistake is permanent.
The three mistakes that actually happen
Wrong network. Sending a token on a network the destination does not support. The funds exist, but at an address nobody controls on that chain.
Wrong address. One wrong character makes an address that either fails a checksum check or belongs to a stranger. Pasting is safer than typing, and checking the first and last five characters after pasting is safer still.
Right address, wrong coin. Some networks share an address format. An address can be valid and still be the wrong destination for the specific token you are sending.
Habits that cost nothing and prevent all three
Copy the address with the copy button rather than selecting it by hand, and never retype it.
Scan the QR code when you are sending from a phone. A QR code cannot drop a character.
Send a small test amount first when the destination is new to you and the sum is large. Paying one fee twice is cheaper than losing the whole transfer once.
Read the network label, not just the coin name. USDT is the coin; TRC20 or ERC20 is the network, and only the network determines where it arrives.
What a wallet can honestly do for you
A wallet cannot undo a confirmed transfer. What it can do is refuse an address that does not match the network you picked, which is what BYCRYPTO checks before a transfer is accepted. That catches the wrong-network case before it costs anything — the one case that is otherwise invisible until it is too late.
