How to choose
Pick by chain
Safe covers EVM chains, Squads covers Solana, and Nunchuk, Unchained and Casa cover bitcoin. Casa also holds ETH, USDT and USDC.
Decide who holds a key
With Unchained, you hold two of three keys and Unchained holds one backup key, so it cannot move funds alone. With Safe, Squads or free Nunchuk, every key is yours to store.
Verify what you sign
In a Feb 28, 2025 statement, the Safe Ecosystem Foundation said the attack on Bybit’s Safe came through a compromised Safe{Wallet} developer machine, and reviewers found no vulnerability in the Safe contracts. Check each transaction on the hardware wallet screen, not only in the web app.
Keep keys on separate devices
A 2-of-3 setup protects you only if the keys sit on different devices in different places.
Who should skip all of these
- Solo users with small balances: a single hardware wallet is simpler.
- Anyone who wants one app for EVM, Solana and Bitcoin: each multisig here covers only part of that set.
- People who cannot coordinate co-signers quickly: every transaction waits for enough signatures.
Bottom line
Use Safe on EVM chains and Squads on Solana; both are free to start.
For bitcoin, Nunchuk is free if you manage the keys, while Unchained and Casa charge $250 a year to share that work.
