Wrapped FRAX wallet

What is Wrapped FRAX (WFRAX)?

First thing to get straight, because it trips up almost everyone: WFRAX is not a dollar token. The FRAX ticker changed hands inside the Frax ecosystem - the dollar-pegged stablecoin now goes by frxUSD, and the FRAX name belongs to the protocol's own coin, which also serves as the native gas asset of the Fraxtal network. WFRAX is the wrapped ERC-20 form of that coin, the same trick WETH plays for ether: a native coin cannot be passed to token contracts directly, so a wrapper makes it behave like a standard token.

From there it travels. WFRAX is deployed as a bridged token across a long list of chains, and each deployment is its own contract with its own balance. The address you use is identical across the EVM chains, which is convenient and also the cause of the classic mistake - sending to the right address on the wrong chain. Fees are always paid in whatever the host chain uses natively, never in WFRAX itself, so a small balance of the local gas coin has to ride along on every chain where you plan to move it.

Supported networks in Tangem (16): Ethereum, Scroll, Polygon zkEVM, Blast, Arbitrum One, Optimism, Base, BNB Smart Chain, Solana, Avalanche, X Layer, Polygon POS, Aurora, Sei Network, Katana, Ink.

Tangem handles that shape of asset without ceremony: the gas coin for each chain sits in the same wallet as the tokens it pays for, and a transfer is authorised by holding the card against the phone - no cable, no charging, no separate device to keep alive. For something you will move across a dozen chains over time, that is a practical way to keep it.
