Polkadot Multisig uses a flexible structure that combines a pure proxy with a multisig, and we refer to this as a vault. This is a structure native to Polkadot that enables a "Gnosis Safe" style multisig, where you can add and remove signers while keeping the address the same. Your funds will be stored in the pure proxy address, which we call the vault address.
If you have previously created a pure-proxy multisig in Polkadot.js or other multisig software, you are able to import it and use it from Polkadot Multisig.
Vaults have properties that define how they work.
| Property | Storage Location | Notes |
| Vault Name | Database | User-friendly name to help remember / distinguish your vault |
| Vault Address | On-chain | An on-chain identity will be displayed in place of the address if available. If you hover over the identity you will be able to see the full address |
| Proxy Type ("Multisig controls") | On-Chain | Defaults to an "Any," but advanced users can specific different types of proxy relationships such as "Governance" or "Non-transfer" |
| Time Delay | On-chain | This is an advanced feature that is not yet supported in Polkadot Multisig |
| Approval Threshold | On-chain | A multisig will have a set of members who can sign. The approval threshold |
| Members | On-chain | The members are the signers on the multisig, who are individuals who can approve transactions. |
