What Are Hot and Warm Vaults?
In institutional crypto operations, “hot” and “warm” vaults define how close funds are to the network and how quickly they can move:
- Hot vaults are always online, optimized for high‑frequency deposits and withdrawals, and protected with strict policy rules and real‑time monitoring.
- Warm vaults hold larger balances with slower movement, adding extra approval layers and security controls while remaining programmable through APIs.
Vaultody combines both vault types in a single MPC platform so you can segment risk, automate flows and still retain full non‑custodial control over your keys and assets.
Why Use Vaultody for Hot & Warm Vault Management?
Vaultody is built for teams that need to move quickly on‑chain without sacrificing institutional controls.
- MPC/TSS security – Private keys are never assembled; signing is distributed across multiple parties and hardware enclaves.
- Policy‑driven governance – Define per‑vault rules for limits, approvers, assets, destinations and time windows.
- Non‑custodial by design – Your business remains the custodian; Vaultody provides infrastructure, not balance‑sheet risk.
- Multi‑chain coverage – Manage hot and warm wallets across leading L1/L2 blockchains, stablecoins and tokens from one interface.
- Real‑time observability – Webhooks and unified logs for every vault, account and address so risk teams can react instantly.
