Crypto address validator
A valid address means it is well formed, not that it belongs to who you think. Clipboard malware and look-alike “address poisoning” swap in addresses that pass every checksum. Compare the whole address with the source, and send a small test amount first.
Questions
What does this check?
Every address format has a built-in checksum. If a character is mistyped, the checksum fails and the address is invalid. The tool also recognises the network (mainnet or testnet) and the address type.
If it says valid, is it safe to send?
Valid means well formed. It cannot tell whether the address belongs to the person you intend. Scammers use clipboard malware and look-alike addresses that are perfectly valid. Always compare the full address and send a small test first.
Why does a lower-case Ethereum address show a warning?
EVM addresses carry their checksum in the capitalisation (EIP-55). An all-lower-case address is valid, but has no checksum to catch a typo.
Can I use the same address on Ethereum and BNB Chain?
The same EVM address exists on every EVM chain, but a token sent on the wrong network may be unrecoverable if the recipient’s wallet or exchange does not support it. Always match the network the recipient asked for.
