TRON Vanity is an online tool for creating customized TRON (TRC20) addresses, letting users search for addresses that match a chosen prefix or suffix. Its browser-based generator repeatedly creates addresses and filters for the requested pattern, with options to recognize repeated or sequential letters and numbers. Users can adjust the number of processing threads to suit their computer and can run multiple generation pages at once. When they find an address they like, they can copy its private key or create and download a UTC/JSON Keystore file, which is compatible with TronLink.

The service emphasizes offline operation and privacy: address generation takes place in the user’s browser, and the site says generated information is not transmitted to or stored on its servers. It supports use without an internet connection and uses a cryptographically secure pseudorandom number generator. Keystore files are protected using AES-128-CTR and a key derivation process based on PBKDF2-SHA256.
