USDH wallet

What is USDH (USDH)?

USDH is a collateral-backed dollar unit from Hubble on Solana. Rather than sitting against a bank balance, it is minted by borrowers who lock crypto collateral in a vault and burned when they unlock it again, with the system designed to keep the collateral worth more than the debt behind it. The peg rests on that mint, burn and liquidation machinery, so it is a soft peg maintained by mechanism, not a redemption guarantee from an issuer.

Two things matter once it is in your hands. First, the ticker is not unique: a separate and unrelated stablecoin also called USDH exists elsewhere in crypto, so confirm which chain and which issuer any deposit address, listing or transfer refers to. Second, this one is a plain SPL token on Solana, which means it lives in a token account tied to your address, created once with a small SOL rent deposit, and SOL pays the fee on everything you do with it.

A dollar token tends to get spent in small, frequent pieces, and that is where the signing step decides whether it is convenient. In Tangem the SOL that covers fees sits in the same wallet as the token, and a payment is approved by touching the card to the phone, with no cable, no charging and no computer in the loop.
