Wrapped Bittensor (Universal) wallet

What is Wrapped Bittensor (Universal) (UTAO)?

Behind each uTAO sits one TAO held by a custodian, and the wrapper exists so that Bittensor's coin can be held and traded on an EVM chain where it does not natively exist. Universal issues these uAssets as one-to-one backed representations with reserves published on chain, and redemption runs through the issuer rather than through a message-passing bridge.

TAO itself is the coin of Bittensor, a network split into subnets where machine-learning work is produced and scored, with TAO issued to the miners and validators taking part. That activity happens on Bittensor's own chain, which uses its own account format and its own staking to validators. None of it is reachable from the wrapped form: while the asset is uTAO, it cannot be delegated, cannot register on a subnet, and cannot pay a Bittensor fee. It is a claim on TAO, priced against TAO, and nothing more. TAO also has a hard cap of 21 million coins, and the wrapper does not change that arithmetic, since every uTAO corresponds to one already issued.

Moving uTAO costs gas in the native coin of the chain it lives on, not in TAO. Redeeming means handing the wrapped token back and receiving native TAO at a Bittensor address, so anyone planning to stake eventually should assume that extra step.

Supported networks in Tangem (1): Base. Keys for the address holding it are created inside the card's chip and stay there; a second identical card, kept somewhere else, restores the same address if the first is lost, and a seed phrase is available if you would rather have one. Someone parking a wrapped claim for a long stretch mostly needs a key that survives the wait, and this is one way to get it.
