3NUM

3NUM was created to solve the fundamental privacy and security flaws of traditional phone numbers. Its core innovation, the 3NUM Shield, transforms a globally routable +1 number into a Web3-native identity secured by your crypto wallet. Unlike SIM-based numbers, 3NUM Shields cannot be SIM swapped, are anonymous by default, and enable secure messaging between wallets, Web3 usernames, or traditional contacts.

The platform is powered by the 3NUM Protocol, which functions as a decentralized telephony stack. It allows users to access encrypted messaging, spam filtering, smart inboxes, and even pay-to-message mechanics using crypto. Currently deployed on Ethereum, 3NUM is expanding minting support to chains like Solana and Avalanche. Users can connect via MetaMask, WalletConnect, or Coinbase Wallet, and communicate over WiFi and data—eliminating the need for legacy mobile plans.

In addition to core communication tools, 3NUM is building out robust ecosystem functionality including smart 2FA, customizable inbox permissions, integration with XMTP and Signal protocols, and support for bringing existing numbers on-chain. Its roadmap includes a tokenized decentralized protocol, relayer incentives, and eventual DAO governance under the 3NUMDAO initiative.

Trusted by investors like BlueYard Capital and Notation Capital, and with a growing user base secured via their Speak.3Z mobile app, 3NUM offers the next evolution in trusted, decentralized communication—one number, fully owned by you.

3NUM offers revolutionary features and benefits that redefine what mobile communication looks like in the Web3 era:

• Web3 Mobile Numbers: The 3NUM Shield is a +1 mobile number that operates as an on-chain identity, fully owned and secured by your wallet.
• End-to-End Encryption: Decentralized, secure messaging and voice calling (launching 2025) between wallets and phone numbers.
• No SIM Swaps: Numbers are wallet-custodied, removing the SIM card attack vector entirely.
