About This Type

32-byte public key identifying a Subtensor account.

The primary account identifier on Subtensor. Every coldkey and hotkey is an AccountId32. Displayed as SS58 addresses (starting with "5") for human readability.

Encoding: Always exactly 32 bytes, no length prefix. SS58 is a display format, not an encoding.

Hex → SS58: encodeAddress(hex, 42) where 42 is the Bittensor network prefix.
