Your Words, In Your World.
Know who you are talking to. Keep your conversations private. Make the moments that matter verifiable.
Officially incubated by @GIWA_by_Upbit via GASOK
Unwanted messages, uncertain identities, and conversations that can disappear or change. UMUL brings privacy, identity checks, and on-chain proof to familiar messaging.
WHAT MAKES UMUL DIFFERENT
From connection to conversation to proof.
One connected experience.
01 / PRIVATE BY DESIGN
Connect with your wallet and exchange end-to-end encrypted messages. Your conversations are designed to be readable only by their participants.
02 / TRUST BEFORE TALK
Check a contact’s verification status through GIWA DOJANG. Messages from unknown people go to requests, so you can review who is reaching out before continuing.
03 / PROOF THAT LASTS
Record mutually approved conversation proofs on GIWA Chain. A hash, not the message text, makes changes detectable while keeping the conversation private.
UNDER THE SURFACE / 01
UMUL separates the messaging network from the chain used for identity checks and proofs. Each system handles only the information it needs.
Messages travel via XMTP end-to-end encryption. Decrypted conversation content stays on participants’ devices; UMUL’s server cannot read it.
Check a wallet’s verification status to learn about a contact, and confirm every participant’s status before creating proof.
DOJANG verification and proof recording happen on the same chain. At submission, the contract rechecks verification and records a hash instead of the conversation text.
UNDER THE SURFACE / 02
A proof is not built on one person’s claim. Every participant checks their own record and signs the same content.
Select the messages to prove and check each participant’s DOJANG verification status.
Each participant recalculates the same conversation hash on their own device.
Only when the hashes match does each participant sign with their wallet using EIP-712.
The contract rechecks verification and records the hash and signatures on GIWA Sepolia.
The original proof is stored encrypted and can only be recovered by a signing wallet’s owner. Compare it with the public hash to detect changes.
SIMPLE TO START
Start with your wallet instead of a lengthy sign-up, and create proof only when it matters.
Connect your wallet and create a UMUL profile.
Verify a contact and exchange encrypted messages.
