3NUM Shields are cryptographically secure, meaning they can be used for end to end encrypted messaging

3NUM Features

Messaging PFP

3NUM Shields include a unique, generative PFP that can visually represent your messaging persona, and is inextricably linked to your mobile number, helping solve the problem “who am I really talking to

No SIM Swaps

3NUM Shields are fully controlled by a users wallet, and are built with smart contracts, not SIM cards, meaning it is impossible for 3NUM Shields to be SIM Swapped

Shielded Numbers

The underlying number of a 3NUM Shield is never made public. Instead, it is hashed and used as the tokenID during the minting process.

Spam Prevention

3NUM puts the user in full control over incoming messages, and includes innovative spam prevention features to stop annoying and dangerous spam in its tracks

No-Dox Number

3NUM Shields are purchased with crypto and require zero kyc info, meaning they can be used as a trusted, no-dox number for popular messaging apps like Telegram, Signal and WhatsApp

Wallet Secure SMS 2FA

Traditional SMS based 2FA is horribly insecure. Because 3NUMs are secured by a users wallet, 3NUM replaces insecure SMS 2FA with the security of SIWE

Web3 Wrapping

Wrap your 3NUM Shield with your favorite ENS or AVVY domain name, allowing users to lookup and message you via your favorite Web3 name

Full 2-Way Call/SMS

3NUM aims to replace your current mobile plan. With 3NUM users can enjoy full call and sms functionality while only needing data access.
