5 Crypto Address Mistakes That Cost Real Money

Blockchain transfers are final. There is no bank to call and no chargeback. The good news: almost every loss comes from one of five predictable mistakes, and each takes seconds to prevent.

1. Sending on the wrong network

Many tokens exist on several chains, and EVM chains (Ethereum, BNB Chain, Polygon, Arbitrum) share the same 0x address format. An address can be valid on all of them while your wallet only watches one. Always check the network name, not just the address. More in USDT TRC-20 vs ERC-20.

2. Forgetting the memo or destination tag

Exchanges use one shared address for XRP, XLM, TON or ATOM deposits and tell customers apart by the memo. Without it, your coins arrive but are not credited. If a memo is shown — when you deposit or in your payout wallet — include it.

3. Address poisoning

Attackers send tiny amounts from addresses that start and end with the same characters as addresses you use, hoping you will copy the wrong one from your history later. Never copy an address from transaction history; copy it from the receive screen or your address book.

4. Clipboard malware

Some malware replaces crypto addresses in your clipboard with the attacker’s. After pasting, compare at least the first six and last six characters with the original.

5. Typos and truncated addresses

Typing an address by hand is asking for trouble. Many formats include a checksum that rejects typos, but not all. Paste, or scan a QR code.

The 30-second checklist

• Copy from the receive screen, never from history.
• Check the network name on both sides.
• Compare the first and last characters after pasting.
• Add the memo if one is shown.
• New address or large amount? Send a small test first.

Our swap form validates the address format for every coin before an order is created, which catches network mix-ups early. Keep your order ID so tracking and support can help if anything looks wrong.
