Frequently Asked Questions
What is a multi-sig wallet?
A wallet requiring multiple private key signatures to authorize transactions, improving security over single-key wallets.
Is 2-of-3 or 3-of-5 better?
2-of-3 offers better usability (any 2 of 3 can transact) while 3-of-5 provides higher security against compromise. Choose based on your threat model.
How does key loss affect security?
If you lose too many keys (>= total - required + 1), the wallet becomes permanently inaccessible. The calculator shows survival probability over time.
