Safe

Safe, formerly known as Gnosis Safe, is a smart contract wallet infrastructure that lets individuals, teams, and organizations secure digital assets and manage on-chain activity using multi-signature approval, meaning a transaction requires sign-off from multiple designated parties before it executes, rather than any single private key holder being able to unilaterally move funds, which meaningfully reduces the risk of a single compromised key or a single rogue actor draining an entire treasury. Because it's implemented as a smart contract rather than relying purely on a traditional single-key wallet, Safe supports flexible configurations, such as requiring three out of five designated signers to approve a transaction, which suits organizations like decentralized autonomous organizations, crypto-native companies, and investment funds that need genuine multi-party control over shared digital assets rather than trusting one individual with sole custody. Safe has become widely used infrastructure across the Web3 ecosystem specifically because its contracts have been extensively audited and battle-tested securing a very large amount of on-chain value over time, which matters enormously in an industry where smart contract bugs have historically led to catastrophic, irreversible losses of funds. Beyond basic asset custody, Safe supports more advanced use cases like managing a treasury's participation in decentralized finance protocols with the same multi-signature security model applied to those more complex transactions. It's aimed at any group or organization that needs shared, secure control over meaningful on-chain assets rather than single-key custody.
