Wrapped TAO (WTAO) is a token that represents the original TAO token on a different blockchain. It is an ERC-20 token, which means it conforms to the Ethereum blockchain's regulations and specifications. The value of WTAO remains equivalent to TAO, maintaining a 1:1 ratio. This token is used to enhance accessibility and liquidity by allowing users to interact with smart contracts on the Ethereum blockchain. It promotes interoperability among different blockchain ecosystems, enabling trading and use-cases not originally possible on the native blockchain of TAO.

To store Wrapped TAO (WTAO) tokens securely, it is recommended to use a cold wallet. There are two types of cold wallets:

1. Paper Wallet: This involves generating public and private keys offline and printing them on a piece of paper. The keys are in the form of QR codes, which can be scanned for future transactions. This method is considered secure as it is offline and not connected to the internet.

2. Hardware Cold Wallet: This is a physical device that stores your cryptocurrency. Your crypto addresses and keys are kept on a USB drive, and only the person with the USB drive can access the assets. Hardware cold wallets are preferred by many users, especially for storing large amounts of coins or tokens.
