What is Coldstar?
Overview
Coldstar enables users to convert standard USB drives into air-gapped cold wallets for the Solana blockchain. The system addresses the security risks of hot wallets by ensuring private keys remain encrypted at rest on offline storage and are decrypted only in RAM for the brief moment required to sign transactions. The tool is used by individuals seeking self-custody solutions without relying on third-party key management.
How it works
Coldstar operates as an open-source command-line tool installable via pip and as a mobile application on the Solana Mobile Seeker dApp Store. Private keys are encrypted using AES-256-GCM with Argon2id key derivation, decrypted temporarily in volatile memory to sign transactions, then immediately wiped. Keys are never written to disk and never touch networked machines, maintaining an air-gapped security model.
Token and supply
COLD is the governance and community token of the Coldstar protocol. The token has a maximum supply of 1 billion, with approximately 1 billion in total and circulating supply.
