STABLEVAULT

One of the WORLDS GREATEST TO KEEP STABLECOINS SAFE

StableVault is a next-generation cold wallet designed and produced by XCards Inc. for the growing stablecoin economy.

Built in a credit-card form factor with e-ink display, numeric keypad, and biometric fingerprint sensor, it provides offline, hack-proof, AI-assisted asset management. Unlike traditional cold wallets that are purely passive storage, StableVault incorporates an embedded AI module to help users track stablecoin yield opportunities, flag suspicious transactions, and optimize portfolio allocations — all without exposing private keys to the internet.
