Rare TRON is an online tool for generating custom TRON addresses that match user-selected prefixes or suffixes, including distinctive number and letter patterns. Designed for creating personalized TRC20 addresses, it searches for matches directly in the user’s browser and lets users adjust the number of processing threads to suit their device. When a preferred address is found, users can copy its private key or create and download an encrypted Keystore file.

The service emphasizes offline operation and privacy: address generation takes place on the user’s computer, and the site says generated information is not transmitted or stored. It supports use without an internet connection and uses a cryptographically secure pseudorandom number generator. Keystore files are encrypted using AES-128-CTR with a key derived through PBKDF2-SHA256. Generated addresses follow the TRC20 standard, and the Keystore files are compatible with TronLink. Rare TRON can also be used on phones and tablets, though the site notes that performance may be better on a computer and can vary by browser, with Chrome currently offering the best results.
