Why a pre-send check matters
Crypto transfers are irreversible. There's no bank to call and no chargeback — once a transaction confirms on-chain, it's final. That's the whole reason a 30-second review before you hit send is worth it. The vast majority of lost transfers come down to four avoidable mistakes: a wrong or tampered address, the wrong network, a missing memo or tag, or simply not testing first. This checklist walks you through each one.
The five things to verify before you send
- Address — copy-paste it, then eyeball the first and last few characters against the source. Malware can silently swap a copied address.
- Network — the sending and receiving network must match exactly (e.g. USDC on Solana → a Solana address). Same coin, different chain, is a common loss.
- Memo / destination tag — if the receiver gave you one, include it. Required on XRP, XLM, Cosmos, and many exchange deposits.
- Fee — confirm the network fee is reasonable for the amount; switch to a cheaper chain for small sends.
- Test send — move a few dollars first, confirm it arrives, then send the rest.
Address-swap malware and how to beat it
"Clipboard hijacking" is one of the most common crypto thefts: malware watches your clipboard, detects a copied wallet address, and replaces it with the attacker's address a fraction of a second before you paste. You think you pasted the right address; you didn't. The defense is simple and free — after pasting, read the first four and last four characters and compare them to the address the receiver sent you. On large transfers, verify the address through a second channel (a call or message) as well. This habit alone defeats the entire attack.
What happens if you skip these checks
Skip the network check and your coins may land on a chain the receiver can't access — sometimes recoverable, sometimes not. Skip the memo and exchange deposits can sit in a pooled wallet awaiting a manual support ticket. Skip the address check and a clipboard swap sends your funds straight to a thief, with no recovery at all. If something has already gone wrong, our Wrong-Network Checker helps you figure out which situation you're in and what, if anything, can be done.
FAQ
Always copy and paste the address — never type it — then verify the first four and last four characters match what the receiver gave you. Clipboard-hijacking malware can swap an address you copied, so the visual check matters. Confirm the network matches too, since the same address format can exist on multiple chains.
Some networks (XRP, XLM, Cosmos) and many exchange deposit addresses require a memo or destination tag — a short code that tells the exchange which account the funds belong to. Leaving it off when it's required can mean the funds land in the exchange's pooled wallet and need a manual recovery request. If the receiver gave you a memo or tag, it is not optional.
A small test send — a few dollars — confirms the address, network, and memo all work before you commit the full amount. If the test arrives, send the rest. If it doesn't, you've only risked a few dollars instead of your whole transfer. It costs an extra fee but it's the single best habit for avoiding a total loss.
