Cold Storage Multisig
Combining offline key storage with a multi-signature requirement for maximum custody security.
Cold storage multisig combines two security practices — keeping private keys offline (cold storage) and requiring multiple independent signatures to authorize a transaction (multisig) — commonly used by institutions and security-conscious individuals holding significant value.
This layered approach means an attacker would need to compromise multiple offline keys, held potentially in different physical locations, rather than a single point of failure.
Examples
- An institution might hold treasury funds in cold storage multisig requiring signatures from geographically separated keys.
- Cold storage multisig combines two independent layers of security rather than relying on just one.
