Unit Plasma wallet

What is Unit Plasma (UXPL)?

Unit Plasma (UXPL) is not the coin of the Plasma network itself but its representation inside the Hyperliquid ecosystem. Unit is the layer that lets assets from other chains enter Hyperliquid: a holder deposits the original coin to an address issued by Unit, a group of independent guardians holds it, and the same amount appears on Hyperliquid as a Unit asset with a U in front of the ticker. UXPL follows that scheme for XPL, the native coin of Plasma. Every UXPL is backed one to one by XPL held on the origin chain, and the reverse path works the same way: send UXPL to a Unit withdrawal address and native XPL arrives on Plasma.

What this means for a holder:

• On HyperEVM UXPL is an ordinary ERC-20. Transaction fees are paid in HYPE, so a small HYPE balance has to sit next to it or the token cannot move.
• The balance does not change on its own. There is no rebase and no accrual built into the token; it stays what you put in.
• The same ticker exists in more than one form. Native XPL on Plasma, UXPL on the HyperEVM side and UXPL on the Hyperliquid spot side are separate holdings, and an address on Plasma will not receive UXPL, even though both networks use the same address format.

That last point is where mistakes happen. In Tangem each form of the asset is its own line, and a transfer goes out from the line you open, so the network is a decision you see rather than a default you never notice. The card signs only what you have chosen there.

If you plan to keep UXPL parked between uses, a card that only comes out when you want to move it fits how this asset behaves: nothing happens to the balance while the key stays offline.
