What is SIMChain Protocol?

SIMChain Protocol is a blockchain protocol designed to bring Web3 identity and finance to everyone with a mobile phone that has a cellular network connection. It transforms any mobile phone number into a secure blockchain wallet and digital identity, enabling access to decentralized financial services without smartphones, internet, or complex onboarding.

Built on the Solana network, SIMChain is tailored for low-connectivity and offline environments, SIMChain will be a revolutionary blockchain solution that makes blockchain technology accessible to everyone. Just dial a short code and you're connected to the global blockchain ecosystem.

Think of it as making blockchain as simple as sending a text message.

The Problem We're Solving

Current Blockchain is Too Complex

Most blockchain and cryptocurrency solutions require:

  • Expensive smartphones
  • High-speed internet
  • Technical knowledge
  • Complex wallet management

This excludes billions of people who only have basic mobile phones or limited internet access.

Traditional Banking Has Limitations

Even for those with bank accounts:

  • High fees for international transfers (3-7%)
  • Slow processing times (1-5 business days)
  • Limited access to new financial technologies
  • Geographic restrictions

Mobile Money is Fragmented

While mobile money (like M-Pesa) has been successful in Africa, these systems:

  • Don't work across borders
  • Are controlled by single companies
  • Can't connect to global financial services
  • Have limited functionality
