🔵The Substrate address standard

SS58 address

SS58 is a simple address format designed for Substrate based chains. SS58 address is base58 encoding of an account’s 32 byte Substrate public key. By default, SS58 address start with number 1 but this can be customized by blockchain developers ( For eg: Polkadot addresses always start with the number 1). Eg: 5DAAnrj7VHTznn2AWBemMuyBwZWs6FNFjdyVXUeYum3PTXFy (public key: 0x306721211d5404bd9da88e0204360a1a9ab8b87c66c1bc2fcdd37f3c2222cc20)

The conversion between 32 byte public key and SS58 representation of an account can be done using the Subkey tool.
