🔥 Clear Signing on Safe is here — with Ledger Multisig. Tens of billions in assets are secured by Safe, the gold standard for onchain multisig. But nearly every team using it shares the same fatal flaw: blind signing. You’re asked to approve a treasury transaction, and all you see is a random hex string. You’re forced to trust your browser. That’s not security. That’s a gamble. And a lot of people are losing at this game. Today, we’re fixing it. Introducing Ledger Multisig, built on Safe, powered by Ledger’s world-class hardware security. It’s the missing link: the security and clarity layer every multisig should have. With Ledger Multisig, Clear Signing comes to every collective operation. No more guessing. Every transaction, amount, destination, contract function, is displayed in plain English on your Ledger’s Secure Screen. What you see is what you sign. Always. For existing Safe users, the transition is instant. No migrations. No setup pain. Just connect your Ledger, your Safes appear, now protected by Ledger security and Transaction Checks. It just works. We’re launching on EVMs today, securing Safe first, and expanding fast. Support for Solana Squads and native Bitcoin multisig is already in development. Our goal: a universal security layer for all on-chain collaboration. And the best part? Ledger Multisig is free. No extra cost. No complexity. Now there’s truly no excuse to blind-sign a treasury transaction. No excuse to “trust” an interface. No excuse for compromise. Secure your collective assets, today.
