SS58 functions

ss58 or substrate58 is an address encoding scheme that is commonly used in substrate-based chains. It is similar to Base58 encoding format, with some modifications.

Under basic ss58 encoding format an address can be encoded as:

base58encode ( concat ( <address-type>, <address>, <checksum> ) )

Functions

from_ss58()

from_ss58(varchar) → varbinary

Converts an ss58-encoded string to the corresponding VARBINARY address.

SELECT 
    from_ss58('1qnJN7FViy3HZaxZK9tGAA71zxHSBeUweirKqCaox4t8GT7')
-- results in VARBINARY 0x2534454d30f8a028e42654d6b535e0651d1d026ddf115cef59ae1dd71bae074e

to_ss58()

to_ss58(varbinary, int) → varchar

Encodes an address of a specific network type into its ss58 VARCHAR representation. For example:

• Polkadot has address type 0
• Kusama has address type 2
• Generic Substrate has address type 42

SELECT 
    to_ss58('0x2534454d30f8a028e42654d6b535e0651d1d026ddf115cef59ae1dd71bae074e', 2)
