Hot wallet

A hot wallet is a wallet whose signing keys are held in systems connected to the network, enabling immediate, often automated, transaction signing. Hot wallets exist for operational speed: client withdrawals, exchange connectivity, and settlement flows, and they carry the highest exposure of the storage tiers.

Running hot wallets safely in a bank

Even hot, keys belong in HSMs, never in application memory; policies cap balances and velocities; destinations are whitelisted; and compliance screening runs pre-signature. The hot tier should hold working capital only, with the bulk of assets in warm and cold tiers.

Taurus-PROTECT manages hot, warm, and cold tiers under one policy engine, so rebalancing between tiers is itself a governed, quorum-approved operation.
