Гаманець для Fathom Dollar

What is Fathom Dollar (FXD)?

FXD does not arrive from a bank account. It is minted against collateral: XDC is locked in a smart-contract vault run by Fathom DAO, and FXD is drawn out against that locked value. The peg to the dollar is soft and maintained by that overcollateralization plus the incentive to buy FXD back cheaply and close a position, which is a different design from a token redeemable one-for-one at an issuer's window. Anyone who minted their own FXD keeps a debt position behind it, and that position can be liquidated if the collateral value drops too far. Someone who simply received FXD carries none of that, but the stability of the token still rests on how those vaults behave.

The practical side is the XDC Network. FXD is an XDC-native token, so every transfer is paid for in XDC and a wallet holding only FXD cannot move it. Keep a little XDC beside it. XDC addresses are commonly shown with an xdc prefix rather than 0x; the account is the same either way, and some tools display one form while others display the other.

Because FXD and the XDC that pays its fees sit side by side in one Tangem wallet, a transfer is a tap of the card against the phone: no cable, nothing to charge, and the fee coin is already where it needs to be. That combination is why an FXD balance is comfortable to keep on a card rather than on a device you have to keep powered.
