0G Sign is a decentralized document signing platform built on 0G Storage. It enables users to upload documents with AES-256 client-side encryption, collect EIP-712 wallet signatures, and verify authen
🔐 Encrypted UploadDocuments are encrypted with AES-256 on the client side before upload. Encryption keys never leave your browser — only you and authorized signers can decrypt. ✍️ Wallet SigningSign with EIP-712 typed data — zero gas fees, cryptographically verifiable. Each signer receives a clear, human-readable confirmation in their wallet. 🌐 Permanent StorageFiles are stored on the decentralized 0G Network with content-addressed root hashes. No single point of failure, no subscription fees. | 🔗 Shareable LinksCreate a signing request and share the link. Counterparties open it, connect their wallet, and sign — no account required. ✅ On-Chain VerificationVerify document integrity and signer authenticity via root hash. Export cryptographic proof as JSON for auditing. 🎨 Dark Glass UIModern dark theme with glassmorphism effects, gradient accents, animated background orbs, and a step-by-step tutorial right on the homepage. |
<p>Built a Web3 document signing DApp on 0G Storage with the following core features:</p><p> 1. Encrypted Upload — Files are encrypted client-side using AES-256 before uploading</p><p> to the 0G decentralized storage network. Keys are managed by the user's wallet — the</p><p> server never sees plaintext.</p><p> 2. Content Addressing — Each file generates a unique Merkle Root Hash, serving as its</p><p> decentralized identifier with on-chain integrity verification.</p><p> 3. EIP-712 Signing — Users sign document hashes on-chain via MetaMask. Signatures are</p><p> publicly verifiable and provide a foundation for legal validity.</p><p> 4. Zero Single Point of Failure — Files are distributed across multiple 0G storage</p><p> nodes. No centralized server dependency, no subscription fees.</p><p> 5. Dual-Mode Architecture — Supports browser-side direct upload (MetaMask signed) and</p><p> server-side fallback upload,兼容 both wallet and non-wallet users.</p><p> Tech Stack: Next.js, TypeScript, ethers.js, 0G Storage SDK, Wagmi, AES-256 Encryption</p><p> Current Status: Core upload and signing flow completed. Debugging testnet node</p><p> compatibility issues.</p>
