MonerOS

View the sourcecode at GitHub (https://github.com/MonerOS-dev/MonerOS). MonerOS is a free, open-source dual-OS ecosystem providing a professional-grade security bridge for your digital assets. By decoupling transaction preparation from private key signing, it eliminates online vulnerabilities. It features two nodes: HotWalletOS, a hardened internet-connected gateway to watch the blockchain and prepare transactions, and ColdWalletOS, a strictly air-gapped offline vault where keys securely sign them. Key features include hardware independence to convert standard amd64 PCs into a vault, true air-gapped security with networking completely disabled, a hardened attack surface where software installation is disabled by default, and a 100% open-source transparent design. Note: MonerOS is in Beta, and Bitcoin support is coming after Monero stress-testing.
