About this app
Datawallet+ | Your Sovereign Financial Operating System
Datawallet+ is not just a crypto wallet. It is the primary gateway to the Datachain Rope blockchain ecosystem, a comprehensive financial operating system that puts your identity, your data, and your assets under your exclusive control.
Whether you are managing a multi-chain portfolio, tokenizing a real-world asset, staking in private pools, or verifying your identity for a regulated offering, Datawallet+ brings every capability together in a single, privacy-first application.
Self-Sovereign Identity
Your identity is anchored to your wallet, not to a server. Datawallet+ generates a W3C-compliant Decentralized Identifier (DID) derived from your own cryptographic keys. On-chain KYC claims via the T-REX / ONCHAINID framework let you participate in regulated token offerings and ERC-3643 security token transfers, with eligibility verified automatically, on-chain, without sharing more than necessary.
Multi-Chain Wallet
Native support for Datachain Rope (DCR-20, DC FAT, DCNFT), Ethereum, Polygon, and XDC Network, all from one interface. WalletConnect v2 lets you connect to any compatible dApp by scanning a QR code or deep-linking. Manage sessions, sign transactions, and switch chains with full transparency and biometric protection.
Encrypted Data Sovereignty
Your personal data belongs to you. Datawallet+ stores your profile, identity claims, and chat history as AES-256-GCM encrypted documents on IPFS, pinned with multi-tier redundancy and readable only with your wallet keys. A built-in Sovereign Data Manager tracks your migration progress and lets you export a complete encrypted archive of your data at any time.
Real-World Asset Tokenization
Tokenize supercars, luxury watches, fine wine, real estate, art, and collectibles directly from the app. Asset metadata is pinned to IPFS for permanent, verifiable provenance. Listings integrate seamlessly with the Tanastok marketplace for secondary trading and institutional visibility.
Staking & Private Pools
Access staking pools across the Datachain ecosystem, including Tanastok private pools and Careaway health ecosystem pools. View real-time APY, total value locked, and your personal stake positions. Accept or decline private pool invitations, all within the app.
Fiat On-Ramp & Neobanking
Buy crypto with traditional payment methods through integrated Onramper support. View enhanced bank account summaries and virtual card interfaces in the FIAT tab, bridging the gap between traditional finance and the decentralized economy.
Encrypted Peer-to-Peer Messaging
Chat and call directly with contacts identified by wallet address, no phone number, no email required. Real-time encrypted messaging, voice calls, and video calls are built in. Contacts are wallet-first: portable, verifiable, and platform-independent.
Post-Quantum Security
Datawallet+ is built for the future. Alongside classical Ed25519 signatures, it implements ML-DSA-65 (Dilithium3) post-quantum signing providing a quantum-resistant security layer without breaking compatibility with today's verification infrastructure.
Ecosystem Hub
Datawallet+ connects natively to the full Datachain Rope constellation: DCSwap (DEX), NaturaProof (environmental certification), AlterOS, Picentriq, Careaway, and Skywatcher with a programmable Datawallet Connect API for ecosystem partners.
Datawallet+ is developed by Datachain Foundation SAS and published through Braincities Lab. It embodies a single thesis: the future of personal finance demands not just a wallet, but a sovereign operating system where identity, data, communication, and financial activity converge under your exclusive control.
