Built on open standards with privacy at its core. Sirr combines the reliability of email with modern messaging features.
Unlike WhatsApp and Telegram, Sirr has no central server, no core node that can be shut down, and stores no user profile information or communication content.
Ultimate privacy - anyone can run a Sirr communication node, forming a truly distributed communication network. All your data can be stored on your own cross-border node, beyond anyone's censorship.
Users on different communication nodes can communicate freely and seamlessly across servers, without needing to know which node the other party is on.
Open source code that can be audited. Verify security yourself or trust the community's review.
All chat content is encrypted using OpenPGP, and only the communicating parties can decrypt and read the messages.
Download Sirr client on Android, iOS, and PC. All content syncs automatically.
No single point of control in the network, making it difficult to block or monitor.
Sirr uses the OpenPGP encryption standard to provide end-to-end encryption for all user communications. OpenPGP was born in 1991 when governments began mass surveillance of electronic communications. Its founder Zimmermann's goal was: to enable ordinary people to use military-grade encryption to protect communication freedom. Later, the core ideas of PGP were organized into an open standard that belongs to no company or government, maintained by global developers, with the open standard being RFC4880/4880bis. OpenPGP does not rely on central servers, does not need CA, each person owns their own keys and is responsible for them. Encryption happens on the client side, keys are never uploaded to servers, the server is just a "blind courier", even if all servers are compromised, attackers can only see encrypted gibberish. OpenPGP's algorithms are public, protocols are public, and have undergone continuous scrutiny by the global cryptographic community for over 30 years. This is the source of verifiable security. Even if one day Sirr no longer exists, users can still decrypt their historical messages. Therefore, Sirr is a system designed for long-term, serious, and secure communication.
Built-in decentralized wallet. When users create an account, a decentralized BNBChain wallet is automatically generated. The private key is only saved on your local client to ensure security. It supports free transfers between users and multi-person gift giving functions in group chats. You can deposit and withdraw at any time.
Available on all major platforms. Start messaging privately today.
Your BSC wallet address serves as your account. No registration required - just connect your wallet or create a new one. You have complete ownership of your identity, secured by your private key.
The built-in BSC wallet lets you manage BNB and BEP-20 tokens, send instant transfers to contacts, create and claim red packets, and view transaction history - all without leaving the app.
Red packets let you share crypto with friends in chats. Create a red packet with BNB or tokens, send it to a chat, and recipients can tap to claim. Great for celebrations, tips, or community rewards.
Yes! Messages are end-to-end encrypted using OpenPGP. Wallet transactions are secured by BSC blockchain. Your private keys never leave your device, giving you full control.
