Is this crypto address validator really offline?

Yes. The tool runs in your browser and does not require any API calls. It validates format and checksum rules locally.

What chains does this tool support?

It supports Bitcoin (legacy and bc1), Ethereum (EIP-55 checksum), TRON (TRX), Solana (SOL), and XRP classic addresses.

Why is checksum validation important?

Checksums help detect typing or copy/paste mistakes before you send funds. A checksum mismatch often indicates a typo.

Can a valid address still be the wrong destination?

Yes. Validation confirms format/checksum only. Always verify the recipient, correct network/chain, and exchange requirements before sending.

Do I need a Memo/Tag for some transfers?

Sometimes. Exchanges may require a Memo/Tag (for example on XRP). Missing it can cause delayed credit or loss, so always follow the exchange instructions.

Q2. Why does checksum matter?
Checksums help detect typing/copy mistakes before you send funds.

Q3. Can a valid address still be wrong?
