Web3 Connectivity and Digital Identity

Depinsim extends mobile connectivity into the Web3 ecosystem by transforming each eSIM phone number into a blockchain-compatible digital identity.

This integration bridges communication, identity, and finance — enabling users to access decentralized services directly from their mobile devices, without relying on external wallets, browser extensions, or complex onboarding flows.

eSIM as a Web3 Identity

Each Depinsim eSIM is mapped to a blockchain address through the FMIP identity layer, turning a phone number into a verifiable on-chain credential.

This enables users to:

• Send and receive crypto using simple, number-based identifiers

• Authenticate securely when interacting with decentralized applications

• Unify communication, identity, and value exchange under a single, self-owned account

With this architecture, the eSIM evolves beyond a connectivity tool — becoming a digital passport for the decentralized internet.

Decentralized Identity (DID) and Privacy

Depinsim integrates Decentralized Identity (DID) standards to ensure full user ownership over identity and personal data.

Authentication and verification occur through on-chain mechanisms, eliminating reliance on centralized authorities and reducing the risk of identity manipulation or access revocation.

Key protections include:

• End-to-End Encryption for messages and identity credentials

• Immutable Ownership of phone numbers and identity keys

• Elimination of SIM Swap Risk through blockchain-level registration and recovery mechanisms

This identity model preserves user sovereignty while maintaining interoperability across the Web3 ecosystem.

Cross-Chain Interoperability

Built on BNB Chain, Depinsim is designed to support interaction across EVM-compatible and major blockchain networks.

Through a single eSIM-linked identity, users can seamlessly access decentralized services across multiple chains, ensuring:

• Universal access to Web3 utilities, DeFi platforms, and decentralized applications

• A future-proof identity layer adaptable to emerging blockchain standards

• Smooth integration across multi-chain ecosystems without fragmented credentials

Through this approach, Depinsim redefines connectivity — not merely as access to the internet, but as direct access to the decentralized economy itself.
