## Description

DeCerta is a decentralized document notarization and storage app. Sign in with a self-custodied wallet, anchor your documents to the SCI Network or BNB Smart Chain, and prove ownership without trusting any single server.<br><br>  How it works<br>  • Pick a file — PDF, image, document, anything up to 50 MB.<br>  • DeCerta hashes it locally and registers a tamper-evidence anchor on-chain.                                               <br>  • File contents are encrypted and split between on-chain proofs and our backend, keyed by content hash.                    <br>  • Only your wallet can authorize retrieval. The app reassembles the file, verifies the hash matches what was anchored, and shows it to you.                                                                                                           <br><br>  Features                                                                             <br>  • Self-custodied wallet — your private key never leaves the device.                                                        <br>  • Mnemonic recovery — restore your wallet on any device.                             <br>  • Two networks — SCI Network for low fees in SCI, BNB Smart Chain for BNB.                                                 <br>  • Tamper-evident — every retrieval re-verifies the on-chain hash before opening.                                           <br>  • Read-only access to legacy documents anchored before our V2 contract upgrade.                                            <br>  • Multi-language UI — English, Turkish, Arabic, Spanish, French, Russian, and more.                                        <br>                                                                                                                             <br>  Use cases                                                                                                                  <br>  • Diplomas, certificates, contracts, deeds, agreements.                              <br>  • Anything you want a verifiable timestamp + content proof for.                                                            <br>                                           <br>  Privacy                                                                                                                    <br>  • Wallet-signed authentication for every API call. No passwords on our servers.                                            <br>  • File contents are end-to-end protected — the backend stores only encrypted packets keyed by hash.                        <br>  • Privacy policy: https://decerta.scimatic.net/privacy-policy                                                              <br><br>  DeCerta is built on Web5 principles: your data, your keys, your control. Public-good infrastructure for a verifiable internet.
