Iran has some of the heaviest internet filtering in the world. Black Cat uses two protocols specifically built to stay connected where ordinary VPNs get blocked: VLESS-Reality (stealth) and Hysteria2 (fast, obfuscated QUIC). No email, no card, no account, pay on-chain with Bitcoin and other cryptocurrencies.
How it works: pick a plan → scan the QR from your wallet app → the link appears the moment the chain confirms, usually under a minute. No signup, no email.
$3/month, 5 devices, both protocols, all locations, unlimited traffic.
Get connected →VLESS-Reality disguises your traffic as normal HTTPS to a real website. Deep-packet inspection sees nothing unusual.
Hysteria2 rotates ports and wraps packets with Salamander obfuscation, so it resists throttling and UDP blocking.
Pay with Bitcoin and other cryptocurrencies, on-chain, no bank, no card. Nothing links the payment to a personal identity.
Your subscription link is your access. Import it into Hiddify, sing-box, or Clash Meta. 5 devices, all locations included.
Pay on the website → receive a subscription link by QR code → import into your VPN app. That's it. No email, no password, no account to create or verify.
Your subscription contains both protocols. When one gets blocked, switch to the other. VLESS-Reality blends with regular TLS traffic; Hysteria2 hops ports and wraps packets so it doesn't look like a VPN at all.
If you lose your subscription link: SOL payers can sign in at /account using a wallet message (SIWS, no private key leaves your device); BTC/ZEC payers use their transaction ID. Your subscription is always recoverable.
