ChangeX
Self-custodial multichain wallet with built-in card, IBAN, swaps, and staking across Bitcoin, Ethereum, Polygon, and Arbitrum.
What is ChangeX?
ChangeX is a non-custodial wallet that combines crypto holdings with traditional finance rails. Users can hold and swap Bitcoin, Ethereum, Polygon, Arbitrum, and other major assets, stake supported tokens for yield, and spend balances directly via a built-in Visa card and IBAN account. The app integrates fiat on- and off-ramps so users can move between traditional banking and self-custodial crypto without leaving one interface.
