Гаманець для Wrapped TAO

What is Wrapped TAO (WTAO)?

What you hold with wTAO is an Ethereum-side claim on TAO that sits locked with a bridge custodian on Bittensor. The wrapper exists because native TAO lives on a Substrate-style network with its own address format, where coldkeys and hotkeys, subnet registration and delegation to validators all happen. None of that reaches wTAO. On Ethereum it behaves like any other ERC-20 - it moves with an ETH fee, sits in the same account as the rest of your tokens, and is redeemed for real TAO only by sending it back through the bridge and unwrapping.

So the two are not interchangeable in use, only in amount. A holder who intends to delegate to a subnet validator has to get back to Bittensor first; a holder who just wants TAO exposure inside Ethereum tooling stays wrapped. The trade-off is that wTAO carries bridge risk that native TAO does not, since the peg depends on the locked coins behind it.

Supported networks in Tangem (1): Ethereum.

A wrapped position like this often sits untouched for months between the day it is minted and the day it goes back over the bridge. Tangem builds the private key inside the card's secure element and it stays there, signing only when the card is tapped; a second card from the same set is the copy that brings the wallet back if the first one is lost, and writing down a seed phrase is a choice rather than a step. Long gaps between transactions are exactly when a key that never left hardware is worth the most.
