Crypto Wallet Address Validator

Cryptocurrency address errors cause billions in losses annually, and the irreversible nature of blockchain transactions means extra caution is essential.

The most common mistake is cross-chain sends: sending Bitcoin to an Ethereum address or vice versa almost always results in permanent loss—the receiving blockchain can't recognize or access those funds.

Similarly, sending tokens to incompatible addresses (like sending ERC-20 tokens to a Bitcoin address) loses funds forever.

Address poisoning is a growing scam: attackers send tiny amounts from addresses that look similar to ones you've used, hoping you'll copy the wrong address from your transaction history.

Always verify the complete address, not just first/last characters.

Clipboard malware is another threat: malicious software detects when you copy crypto addresses and substitutes the attacker's address.

Always verify the pasted address matches what you copied.

QR code scams involve overlaying fake codes on legitimate payment requests—verify the address shown matches what you expect.

Smart contract addresses versus wallet addresses cause confusion: sending tokens to a token's contract address usually burns them permanently.

Exchange deposit addresses have additional requirements: some cryptocurrencies require memo/destination tags (like XRP or XLM)—omitting these can result in lost deposits that take weeks to recover, if possible.

Address reuse hurts privacy: while technically safe, using the same address repeatedly allows anyone to track your entire transaction history.

For security, use hardware wallets for large amounts, verify addresses on the device screen (not just computer), enable address whitelisting on exchanges, maintain an address book of verified addresses, and never share private keys or seed phrases—legitimate services never ask for these.

Remember: if you make a mistake, there's no customer service, no chargeback, and no recovery.

Triple-check everything.
