Keeping your First Digital USD safe - how Zypto handles security
Zypto App is non-custodial. Your private keys are generated and stored on your device. Zypto never has access to your FDUSD, and every transaction is signed locally. For higher security, pair with the Vault Key Card, the card-based cold-wallet hardware that signs transactions over NFC without exposing keys to the internet.
What is First Digital USD?
First Digital USD, traded as FDUSD, is a US dollar stablecoin built to hold a steady value of about one dollar. It follows a fully collateralized model, where each token is intended to be backed by cash and cash-equivalent reserves held with a trust partner and redeemable on a one-to-one basis. FDUSD runs across several networks, including Ethereum, BNB Chain, Solana, Sui, and Arbitrum, giving users flexibility in where they hold it. Its reserves are described as held in segregated accounts separate from the issuer's operations. As with any fiat-backed stablecoin, its dependability rests on the strength of its reserves. You can track the First Digital USD price and hold FDUSD in a self-custody wallet.
