AML check on Bittensor

Bittensor (TAO) is a Substrate-based network for AI subnets. Native addresses start with 5, and funds sit on the wallet's coldkey, not its hotkey.

Address formatStarts with 5 · SS58 format (prefix 42); the coldkey address holds the funds57V8Q2sgn2PLZGo69SZHQccCEH3sczarQ6FjVyoqgRxZtPmuExample for illustration, not a real address.
Note

When checking a Bittensor wallet, screen the coldkey address (starts with 5), since that's the one that holds TAO. A 0x address is a Bittensor EVM account, which maps to a separate native 'mirror' account.

How to check a Bittensor address

  1. Get the public addressAsk your counterparty for the address they will send from — or copy it from the incoming transaction.
  2. Pick a service that covers BittensorChoose one marked “Supported” in the list above. Only send TAO to a coldkey address. The official docs warn that sending it to a hotkey can strand the funds.
  3. Run the check and read itKeep your coldkey and seed phrase offline where you can, and never type the phrase into apps, chats or cloud documents.
A real AML check needs only a public address. Never share a seed phrase or private key.

Bittensor specifics

  • Every Bittensor wallet has two keys: the coldkey holds funds and signs transfers and staking, while the hotkey is an operating key that validators and miners use on subnets.[1]
  • The official docs say to always send TAO to a coldkey address; sending to a hotkey address is technically possible but can strand the funds.[2]
  • Bittensor is split into subnets, each an independent incentive market with its own token (called alpha) that trades against TAO.[3]
  • Staking backs a validator's hotkey with your TAO; on a subnet, staking swaps TAO into that subnet's alpha at the pool price, so the position's value follows that price, while on the root network (netuid 0) stake stays in TAO.[4]
  • Bittensor also runs an EVM with 0x (H160) accounts usable in MetaMask (mainnet chain ID 964); MetaMask assumes 18 decimals while native TAO uses 9, so amounts can look different for the same funds.[5]
  • In July 2024 a malicious version (6.12.2) of the Bittensor Python package stole users’ unencrypted coldkey details. On 2 July the Opentensor Foundation put chain validators behind a firewall and switched the network to safe mode, stopping all transactions; it says the blockchain itself was not affected.[6]

FAQ

Which Bittensor address should I check: the coldkey or the hotkey?

The coldkey. According to the official docs it holds funds and signs transfers and staking. The hotkey is an operating key used for work on subnets.

Why does my Bittensor key show a different address on another Substrate or Polkadot chain?

SS58 addresses include a network prefix, so the same public key encodes to a different address on each chain. Bittensor addresses use prefix 42 and start with 5.

Is there native USDT or USDC on Bittensor?

No. As of October 2026, Bittensor isn't on Tether's list of supported USDT blockchains or on Circle's list of native USDC chains.

How do I check a Bittensor address for AML risk?

Copy the public address, open one of the services listed above that supports Bittensor, and run the check. You never need a seed phrase or private key.

What does “Not verified” mean?

The service claims support somewhere — in marketing copy or a third-party page — but its own docs, pricing or FAQ do not list the network. Treat it as unknown.
