Validating TRON Addresses Securely

Published: July 14, 2025

All TRON addresses begin with a T when in Base58 format. Internally, they are derived from a hex address that starts with the 41 prefix. This prefix distinguishes them from Ethereum addresses, which start with 0x.

TRON and Ethereum both use the same key pair generation algorithm (ECDSA with secp256k1). The main difference lies in the address prefix and encoding:

• TRON hex addresses start with 41
• Ethereum addresses omit this prefix and start with 0x
• Base58Check encoding of a TRON hex address results in a Base58 address that starts with T

For example, the TRON Base58 address: TNPeeaaFB7K9cmo4uQpcU32zGK8G1NYqeL
corresponds to hex: 418840E6C55B9ADA326D211D818C34A994AECED808
