eSIM Wallet Smart Contract

Every eSIM is linked to a unique eSIM Wallet, providing an on-chain representation of the eSIM. Users can purchase data bundles through these wallets. For instance, if a user has three eSIMs, three corresponding eSIM Wallets will be deployed, each linked to a unique eSIM. The eSIM Wallets can pull ETH from the Device Wallet, offering a streamlined experience without requiring individual top-ups. Users retain full control over their eSIM Wallets and can revoke or update permissions for each one.

For seamless synchronization, a backend server securely generates unique identifiers for the device and eSIMs. These identifiers are stored in the respective wallets, ensuring secure eSIM generation and accurate data bundle application.
