Definition
A wallet that requires approval from several signers before executing a transaction. On Solana, multisigs commonly hold program upgrade authorities and treasury funds instead of a single key.
Why it matters
A single private key controlling upgrades or treasury funds is a single point of failure. A multisig spreads that control across people and devices, which is why auditors and investors look for one.
What to check
- Ask who the signers are, what the threshold is, and whether keys sit on separate hardware wallets.
- Ask how signers are replaced if someone leaves the team.
Related terms
- Upgrade authorityThe key allowed to replace a deployed program’s code.
- Mint authorityThe key allowed to create new tokens of a given mint.
- Freeze authorityThe key that can freeze token accounts of a given mint, preventing transfers.
