USD1 wallet

What is USD1 (USD1)?

A dollar stablecoin from World Liberty Financial, USD1 is meant to sit at one US dollar and stay there. Each token is backed by short-term US government debt, dollar deposits and cash equivalents held with a regulated custodian, and it is redeemable for dollars through the issuer and its partners. It does not rebase, does not pay interest to holders and has no built-in mechanic that changes the number in your wallet: one USD1 today is one USD1 next year unless you move it.

Do not confuse USD1 with WLFI. WLFI is the protocol's governance token with a floating price and its own contract; USD1 is the stablecoin. They come from the same issuer and both show up in the same ecosystem lists, so check the ticker before you send or accept either one.

USD1 started on Ethereum and BNB Smart Chain as a standard ERC-20 and BEP-20 token and has since been issued on other chains, with cross-chain transfers handled by an interoperability protocol. Where it lives shapes what you need next to it:

• On Ethereum, BNB Smart Chain, Mantle and Monad your address is the same string, but each balance is separate and each transfer is paid in that chain's own gas coin (ETH, BNB, MNT, MON).
• On Solana it is an SPL token, so the first deposit opens a token account that costs a little SOL in rent, and every send burns a fraction of SOL.
• On TRON it is a TRC-20 token; transfers consume energy and bandwidth, which in practice means keeping some TRX in the same wallet.

Supported networks in Tangem (6): Ethereum, BNB Smart Chain, Solana, TRON, Mantle, Monad.

Because the same USD1 can sit on several chains at once, the Tangem app keeps a separate USD1 balance for each network and labels the network a transfer will leave on before the card signs it. That gives you a moment to match the network to what the recipient asked for, which for a multi-chain stablecoin is the detail that matters most.
