Decaying Multisig

This model reduces the threshold of signatures over time to mitigate for some keys to be lost without locking the funds forever. As long as the wallet is used, the spending conditions are strict. If no transaction is signed for a long time, the threshold reduces to allow for recovery.

Expanding Multisig

This model does not reduce the number of keys required, instead it increases the pool of keys able to sign. This allows for example to have a recovery key held by the board of directors, only valid in case of a deadlock between the funders. These keys can also be held by third parties such as custodians, without sacrificing self-custody unless a timelock expires.

Safer Backups

The backup mnemonics can be timelocked, drastically the risk of theft and break ins. As long as an access to a backup key is detected before expiry of its timelock, the attacker cannot steal funds.

A combination of these tools can make your institutional wallet more secure against theft, and resilient to loss than the regular semi-custodial or multisig enterprise wallet.
