Crypto Address Format Checker
One mistyped character or the wrong chain on an on-chain transfer, and the coins are gone for good. Before you send, paste the receiving address here and check which chain its format belongs to and whether it is valid. The check runs only in your browser; the address is never uploaded.
Paste the receiving address
Waiting for an address
Paste an address on the left to check the format automatically
Check the first and last few characters, not just the middle — a lot of clipboard malware only swaps the middle.
Confirm the chain matches: if the recipient takes TRC20-USDT, you must use the TRON chain; pick the wrong one (sending as ERC20, say) and the funds can be lost outright.
The first time you send to an address, test with a small amount and confirm it arrives before sending more.
This tool only checks the address format (character set, length, which chain), and cannot confirm the address really belongs to your recipient, nor does it look up on-chain balances. A valid format does not mean you are sending to the right person. Always re-check the full address with the recipient and test with a small amount first. For reference only.
