Fantom wallet

What is Fantom (FTM)?

FTM is the coin of the Fantom Opera network, an EVM chain that reached consensus through its Lachesis protocol and became known for transactions that confirm in a second or two for a fraction of a cent. On Opera the coin is native: it pays gas directly, and it is what validators and delegators stake to secure the chain.

The complication with FTM is that it has never existed in only one form. Alongside the native coin, versions of FTM have circulated on other chains, and a holder can end up with a balance that looks right and is sitting in the wrong place - the wrong version cannot pay Opera gas or be staked there, and reaching Opera means a bridge rather than a transfer. There is a second migration in FTM's story as well: the Fantom network's successor chain, Sonic, introduced the S token, with FTM convertible to it. Which form you are actually holding is worth establishing before you move anything.

Supported networks in Tangem (2): Fantom, BNB Beacon Chain.

Tangem keeps each of those as its own balance instead of merging them, and the network a withdrawal goes out on is shown on screen before the card signs. That is a check you have to perform yourself, since an address gives no hint which chain the person on the other end is watching - but having it in front of you, with a card that only signs when you touch it, is a reasonable way to hold a coin that exists in several forms.
