Project 20 - SuiSign @SuixSign is a blockchain-based tool that lets you securely sign, verify, and store documents online without relying on a middleman. It ensures signatures are permanent, tamper-proof, and easily accessible on @SuiNetwork and @WalrusProtocol. x.com/Silverhard_/status/195…

Ever had that situation where a signed document suddenly goes missing? Or when someone doubts if a signature is real? Yeah, it’s frustrating. But what if I told you it doesn’t have to be that way anymore? .@SuixSign is the solution. Overflow series 20 ↓🧵 @GiveRep

→ What is @SuixSign? It is a blockchain based tool that enables you to sign documents online without relying on a middleman. You can upload a file, choose who you want to sign it and then store those signatures permanently onchain using @SuiNetwork and @WalrusProtocol. This means the signatures can’t be altered, faked or lost and there is no central company controlling the process.

→ What can you use @SuixSign for? - Multi-signature verification You can get multiple people to sign a single document and each signature is securely authenticated and kept in the blockchain so it can't be faked. - Decentralized and zkLogin-Powered The app isn't owned by anyone centrally and you can log in using Gmail without giving away your information and having it kept secure on the blockchain. - Dynamic agreement fees The cost to sign depends on how many people are signing and how much space the document needs. Normally, the signer pays, but the sender can choose to cover it instead.

→ How does @SuixSign works? 1. Upload or select draft Choose an old draft or upload a new PDF. You can even make it public if you want. 2. Define sign areas and add signers Show exactly where to sign and add the email or wallet address of each signer. 3. Send and pay agreement fee The signer or sender pays a small fee for storage and blockchain processing. A secure link is sent. 4. Signer reviews and signs The signer opens the document, signs in the marked spots and confirms it on the blockchain.

→ What makes @SuixSign different? - Strong security Your documents are protected by advanced blockchain technology so no one can fake or forge them. - Fast results Get documents signed and verified in minutes, with instant blockchain proof, no waiting days for approvals. - Full privacy Your files are encrypted and sent on a secure network so that only you are in control of them. - Fair pricing No charges to sign up or unexpected fees, you just pay for what you use.
