Wrapped Fantom wallet

What is Wrapped Fantom (WFTM)?

Wrapping exists because a chain's own coin is not a token. On Fantom Opera, FTM pays for gas and staking but has no ERC-20 interface, so contracts that expect a standard token cannot handle it directly. WFTM solves that: deposit native FTM into the wrapper contract, get the same amount back as an ERC-20 balance, burn the WFTM later and the native coin returns one for one. The rate never drifts, and the only cost of going in or out is the network fee.

That is the Fantom-side story. The versions of this asset that live on Ethereum and BNB Smart Chain are a different thing wearing a similar name: bridged representations, issued by a bridge that holds the original. They cannot pay gas on their host chain, so an ERC-20 balance needs ETH and a BEP-20 balance needs BNB before anything can move. Fantom itself has since been reorganised as Sonic, with FTM converted to the S token, which means a wrapped or bridged FTM balance may point back to a chain that has moved on.

Since the same ticker appears on several chains at once, Tangem keeps each chain's balance separate and names the network a transfer is leaving from on the screen you confirm before the card signs. Read that line first: an address can look identical on two EVM chains while only one of them holds your coins. Checking it yourself, once, keeps this arrangement working.
