Arcanus is a decentralized privacy protocol on Arc Mainnet. It is a dePIN network for encrypted communication, not a single-company VPN with a yearly plan. The same dashboard gives you encrypted tunnels through independent city nodes, wallet-to-wallet voice, sealed mail, and live messenger. You pick a live city, pay for capacity, and import a WireGuard or V2Ray file into the official app for VPN. Voice uses your 0x address as the number, with no SIM and no carrier in the middle. Encryption starts on the device and stays there, so operators see receipts and requests, not plaintext. Incoming mail and chat stay open. You spend $ARCANUS to use the network, while native USDC on Arc covers gas.
