Browse, talk, publish and share privately. Every computer is a node, and no single one of them is in charge.

Two ways to use HidraNet
A browser to get onto the network, and the infrastructure to publish on it — anonymously.

Publish sites, chat, mail and forums without revealing your IP or identity. No central servers, no single point of failure.

// Architecture
The 6 pillars of HidraNet
A network built to stay up and to protect the people using it.
Hardened cryptography
Noise handshake with a hybrid X25519 + ML-KEM-1024 key exchange. Traffic captured today does not become readable when a quantum computer exists.
Onion routing
3 to 7 hops with chaffing. Your IP is never exposed to the other end.
DHT Kademlia
Fully decentralised. No central servers, no single point of failure.
Obfuscation
Traffic indistinguishable from ordinary HTTPS.
Hidden services
Publish .hidra sites without revealing your IP or identity.
Native apps
Chat, mail, forum and site builder — all anonymous, all built into the browser.
// Ecosystem
Everything you need, anonymously
Native apps built into HidraBrowser — no sign-up, no trace.
Chat
E2E messages, no phone number, no history on servers.
Encrypted mailboxes with .hidra addresses.
Forum
Persistent public communities, hard to take down.
Site builder
Publish .hidra pages in minutes, without revealing who you are.

Opening it on a Mac
HidraBrowser is not signed with an Apple Developer ID, so macOS blocks it on first launch. On Apple Silicon the message is “HidraNet.app is damaged and can’t be opened” — the download is fine; macOS says that about any unsigned app. Three commands fix it:
xattr -cr HidraNet.app
codesign --force --sign - \
HidraNet.app/Contents/Resources/bin/tor/tor
codesign --force --deep --sign - HidraNet.app
The bundled Tor has to be signed on its own, and before the app:
--deep does not reach binaries under Resources/.
Skip that line and the browser opens but cannot connect — it reports
“tor exited with code null”.
The ZIP also contains Start HidraNet.command, which runs all of them
for you, and README-macOS.txt with the full walkthrough.
Still blocked? On macOS 15 (Sequoia) and later, right-click → Open no longer works — Apple removed it. Go to System Settings › Privacy & Security, scroll down, and click Open Anyway.
Why not just sign it: signing and notarising requires a paid Apple Developer account. Until the project has one, we would rather explain two commands than claim the app is signed when it is not.
// Principles
Privacy is a right, not a feature. HidraNet is built so that keeping your communications to yourself does not require asking anyone's permission.
// Support
Support the network
No ads, no tracking, no data to sell. Relay bandwidth, exit nodes and development are paid for directly — by the people who use the network.
Support with $HNET
Solana · send to this walletPays the running costs: relay and exit bandwidth, build infrastructure, releases. Any amount, no account, nothing to sign up for.
HNET support wallet
$HNET on Solana only. This is a wallet, not
the token: the mint below ends in pump, this address does not.
Bitcoin and coins from other networks cannot arrive at a Solana address.
The HNET token
Solana · SPL token · for verifying, not sendingThe community token around the network. Holding it funds the same work and nothing else — it is how the people who believe in the project back it in public.
HNET mint address
This is the token, not a wallet — never send anything to it. Check it character by character before you buy: anyone can create a token and copy a name. HNET is not an investment, carries no claim on HidraNet and promises no return.
