What Is Multisig? How Multiple Signatures Protect Your Crypto Assets
The bottom line: a vault that won't open without multiple approvals
Multisig (multi-signature) is a mechanism that requires multiple signatures (approvals) to execute a transaction. For example, you can set it up so that "2 of 3 people must approve before funds can be sent (2-of-3)." The key advantage is that even if one key is stolen, no one can move funds alone. It's well suited to managing team and DAO treasuries, as well as storing high-value personal assets. On Solana, protocols like Squads are widely used.
Key points of this article
Multisig = a mechanism where a transaction can't go through without multiple signatures (e.g. 2-of-3). Benefits = a single leaked key doesn't cause immediate damage, and permissions are distributed across a team. Solana's flagship = Squads Protocol (used by DAOs and funds, publicly reported as formally verified). It becomes even more robust when combined with seed phrase management and a hardware wallet. For the fundamentals, see the account model.
How it works (the simple version)
It's the same idea as a company check that "requires the signatures of multiple executives." With multisig, a transaction is only executed once a predetermined number of signatures (the threshold) has been collected.
| Example setting | Meaning |
|---|---|
| 2-of-3 | Executes with approval from 2 of 3 people |
| 3-of-5 | Executes with approval from 3 of 5 people |
When is it used?
- Managing DAO and project treasuries: distributes authority to prevent solo fraud or mistakes
- Fund and corporate asset management: makes a multi-person approval flow mandatory
- High-value personal storage: splits across multiple devices and keys to spread risk
On Solana, Squads Protocol is used as the standard multisig, and it has been publicly reported as adopted by DAOs, funds, and projects such as Helium, Jito, and Pyth. It also offers features like timelocks and spending limits.
Powerful, but operational design matters
Multisig is powerful, but if you misconfigure the threshold or key-storage design, you can end up in a situation where "no one can move the funds (the keys are lost)." If you adopt it as an individual, make sure you fully understand the mechanism before testing with a small amount.

Frequently asked questions
Q. What is multisig? A. It is a mechanism that requires multiple signatures to execute a transaction. Even if one key is stolen, funds cannot be moved alone, which makes it well suited to managing team funds or high-value assets.
Q. What multisig options are available on Solana? A. Squads Protocol is the leading choice, and it has been publicly reported as used by DAOs, funds, and major projects.
Q. Can individuals use it? A. Yes, but if you misconfigure the threshold or key-storage design, you may end up unable to move your funds. It is safest to understand it first and test with a small amount.
