FAQ — TON wallet addresses

      
What is a user-friendly TON address?

      
A 48-character base64url string (often starting with EQ or UQ) that encodes workchain, 256-bit account id, bounceable/test-only flags, and a CRC16 checksum.

      
Does this tool send my address to a server?

      
No. Parsing and CRC checks run in JavaScript in your browser.
