API Description
Use Cases
  • Simplified Cryptocurrency Transactions: Users can send or receive cryptocurrency using phone numbers, making the process more accessible and user-friendly.
  • Web3 Identity & Authentication: The API enables unique identification in the web3 ecosystem, facilitating user authentication and verification services.
  • Tokenization of Physical Assets: Companies can tokenize real-world assets and link them to phone numbers, enabling easier investment and trading of digital assets backed by physical items.
  • Customer Loyalty Programs: Businesses can implement loyalty programs where customers earn tokens or rewards linked to their phone numbers.
  • Voting & Decentralized Governance: The API can be used in voting systems and decentralized autonomous organizations (DAOs), allowing users to participate in collective decision-making using their phone numbers.
  • E-commerce Integration: Online platforms can enable cryptocurrency payments based on phone numbers, streamlining the checkout process.
  • Decentralized Identity Management: Managing decentralized identifiers (DIDs) within the web3 ecosystem by linking them to traditional phone numbers.
Benefits
  • Simplified User Experience: Users no longer need to manage or remember complex blockchain addresses. Transactions become as easy as sending a message via phone number.
  • Improved Security: Validates phone number ownership, adding an extra layer of security to blockchain transactions implementing strict authentication using 3-legged OAuth tokens.
  • Privacy-Focused: Respects user consent and data privacy, aligning with modern data protection regulations.
  • Interoperability Across Telcos & Web3 Ecosystem: Promotes standardization across different telecom operators (MNOs) and blockchain platforms, facilitating wider integration and usage.
  • New Revenue Streams: Opens opportunities for telecom operators to participate in the growing web3 ecosystem.
  • Operational efficiency for the API customer (cost savings).
