Unit Solana wallet

What is Unit Solana (USOL)?

Holding USOL is not the same as holding SOL on Solana. Unit is the tokenization layer that brings outside coins into the Hyperliquid stack: you send the native asset to a deposit address Unit generates, Unit holds the original, and a matching balance appears on the Hyperliquid side. USOL is that representation of Solana's native coin, and on HyperEVM it behaves like any ordinary token there.

That has practical consequences. USOL carries none of Solana's own functions: there is no staking with it, and transfers of it are paid for in HYPE, the gas coin of HyperEVM, rather than in SOL. Getting back to the Solana network is a withdrawal through Unit to a Solana address, not a normal transfer. Until that happens, the balance lives entirely on the Hyperliquid side.

The other thing to keep straight is that wrapped and bridged versions of SOL exist on many chains, and they are not interchangeable with one another. A USOL balance only makes sense in the place Unit issues it.

Supported networks in Tangem (1): HyperEVM.

Tangem keeps every network as its own line and names the chain a transfer is leaving on, so you can compare that against what the receiving side expects before the card signs anything. Keeping USOL here works because the wallet never blurs your Hyperliquid-side holdings together with anything you hold on Solana itself.
