Trustless. Secure. Sovereign.
Cryptocurrencies require a platform that is secure, trustworthy, and fully under your control. That’s why we don’t offer a web or mobile app—they’re inherently insecure and often subject to outside control.
Built for local sovereignty
No cloud. No tracking. No accounts. Everything important stays on your device.
Runs on Your Device
Our software runs locally on Linux, Windows, and macOS—no cloud, no third-party tracking. You remain in full control: your data cannot be accessed, seen, or intercepted by anyone else. All sensitive information, including private keys, transactions, and settings, is stored in encrypted databases on your machine.
No KYC. No Accounts.
We don’t ask for your email, phone number, passport or ID. You simply launch the app and create local databases. Unlike other platforms, there's no sign-up process and no server-side identity.
Your Data Stays Local
Everything runs on your device—no syncing, no uploads, no surveillance. All critical data is sealed in an encrypted vault file that only you control.
Transparent Fees
We earn from transaction fees—clearly shown in the app, no hidden charges. Check them anytime under the Fees menu.
Why Off-Chain Isn't Sovereign
Centralized platforms often settle trades off-chain—inside private databases rather than on the blockchain. This creates hidden risks: transactions may be frozen, reversed, or disclosed without your consent.
Onisin is built to keep transactions on-chain, giving you visibility and control.
OECD CARF: Global Crypto Reporting Begins 2026
Starting January 1st, 2026, the OECD's Crypto-Asset Reporting Framework (CARF) will require platforms operating in many jurisdictions to report user transactions to tax authorities.
Most off-chain providers will be subject to this—by design. Our app is different: it doesn't collect personal data, and your encrypted data never leaves your device.
You remain independent—even under evolving regulation.
