I want to learn more about the advanced options of adding a wallet in Keeper.

Add a wallet (Advanced):

Timelock: Use this option when you want to store away your sats and only access them on a future date or block height.

Degrading Multisig: Setup this wallet when you perceive a scenario where you need lesser number of keys to access your bitcoin over time. For example, you could setup a 5-of-5 degrading multisig to require all 5 keys for immediate use. Only requiring 3-of-5 keys 6 months later, only 2 keys a year later and just 1 key 2 years after the initial 5-of-5 was setup.

Custom Multisig: Decide the configuration you want to have for a multisig setup. Ideal for businesses hodling and transacting in bitcoin.
