UpRock wallet

What is UpRock (UPT)?

UpRock belongs to the DePIN corner of Solana: networks where ordinary devices contribute a resource and the chain keeps the accounting. In UpRock's case the resource is unused internet bandwidth from phones, pooled so that web data can be gathered from many places at once and fed into AI systems that need current, varied material rather than a frozen snapshot. UPT is the SPL token that network is denominated in.

The practical thing to understand is that there are two different places a UPT balance can sit. One is inside the mobile app that runs the bandwidth side, where a balance is an entry in a service. The other is your own Solana address, where the token is genuinely yours and moves only when your key signs. Those are not the same, and a token that has not been withdrawn to an address you control is not in your custody. Once it is on-chain it behaves like any SPL holding: it sits in a token account attached to your address, and sending it costs SOL, so a little of that should be waiting in the wallet.

This also creates a neat separation with Tangem. The phone doing the bandwidth work never has to be the thing guarding the key, because the key is made inside the card and stays there; you bring the card to the phone only for the moment a transfer is signed, then it goes back in a pocket. Splitting the device that participates from the device that holds is a sensible way to run a DePIN token, and that split is exactly what the card gives you.
