Overview
Safe (formerly Gnosis Safe) is the industry-standard multi-signature wallet for Ethereum and EVM-compatible chains. It secures over $100 billion in digital assets and is used by leading DAOs, protocols, and organizations to manage their treasuries. Unlike traditional wallets that rely on a single private key, Safe requires multiple signers to approve each transaction, dramatically reducing the risk of theft or unauthorized access. Safe is a smart contract-based wallet, meaning it lives on the blockchain and offers programmable security rules. It is fully open-source and has been battle-tested since 2018.
Pros & Cons

- ✓Extensive dApp integration via Safe Apps
- ✓Fully open-source and battle-tested
Cons
- ✗Requires gas fees for each transaction
- ✗Complex setup for beginners
- ✗Primarily Ethereum and EVM chains only
- ✗Multi-sig coordination can be slow
Multi-Signature Security
Safe's core feature is multi-signature (multi-sig) transaction approval. When creating a Safe, you define the number of owner addresses and the threshold required to execute transactions (for example, 3-of-5 means any 3 of 5 owners must approve). This means no single person can unilaterally move funds, which is essential for organizational security. Each signer can use their own wallet (MetaMask, Ledger, Trezor, etc.) to approve transactions. The threshold can be changed later through a multi-sig approved transaction.
Safe Apps Ecosystem
Safe includes an app store called Safe Apps that lets you interact with DeFi protocols directly from the Safe interface. You can access Uniswap, Aave, Compound, Lido, Yearn, and dozens of other protocols without leaving the Safe dashboard. Transactions initiated through Safe Apps go through the same multi-sig approval process. This means your organization can participate in DeFi, manage NFTs, and execute complex transactions while maintaining the security of multi-sig approval for every action.
Transaction Batching
Safe supports transaction batching, which allows you to combine multiple actions into a single multi-sig approval. For example, you can approve 10 token transfers, 3 DeFi interactions, and 2 contract calls as a single batch. All signers review and approve the batch, and all transactions execute atomically. This saves significant gas fees compared to executing each transaction individually and reduces the coordination overhead for multi-sig teams.
Modules & Guards
Safe's programmable architecture supports modules and guards that extend its functionality. Modules can add features like spending limits (allowing small transactions without full multi-sig approval), recurring payments, role-based access control, and automated DeFi strategies. Guards add validation rules that must pass before any transaction can execute. These programmable elements make Safe adaptable to complex organizational needs beyond simple multi-sig approval.
DAO Treasury Management
Safe has become the default treasury management solution for DAOs and crypto organizations. Major protocols like Uniswap, Aave, ENS, and Lido use Safe to manage billions in treasury assets. The multi-sig structure maps naturally to DAO governance, where council members or elected signers must collectively approve fund movements. Safe integrates with governance tools like Snapshot and Tally, allowing governance proposals to trigger multi-sig transactions when approved by token holders.
Supported Chains & Deployment
Safe is deployed on Ethereum mainnet and most major EVM-compatible chains including Polygon, Arbitrum, Optimism, Avalanche, BNB Chain, Gnosis Chain, Base, and others. You can create separate Safe wallets on each chain or use the same set of signers across multiple chains. Creating a Safe requires a blockchain transaction and incurs gas fees. The Safe web interface at app.safe.global provides a unified dashboard for managing Safes across all supported networks.

Frequently Asked Questions
What is a multi-sig wallet?
A multi-signature (multi-sig) wallet requires multiple private key holders to approve a transaction before it can execute. For example, a 2-of-3 multi-sig requires any 2 of 3 designated signers to approve. This prevents any single person from moving funds unilaterally and protects against key theft, insider threats, and single points of failure.
Do I need a Safe wallet as an individual?
Safe is primarily designed for organizations, DAOs, and teams. Individual users can benefit from multi-sig if they want to distribute their key security (for example, using multiple hardware wallets as signers). However, for most individual users, a hardware wallet like Ledger or Trezor provides sufficient security with less complexity.
How much does it cost to create a Safe?
Creating a Safe requires deploying a smart contract, which costs gas fees. On Ethereum mainnet, this typically costs $20-$100 depending on network congestion. On Layer 2 networks like Arbitrum or Optimism, creation costs are usually under $1. Each transaction executed through the Safe also incurs gas fees.
Can I recover a Safe if signers lose their keys?
Recovery depends on your threshold setup. If you have a 2-of-3 Safe and one signer loses their key, the remaining two signers can approve a transaction to replace the lost signer. If enough signers lose their keys that the threshold cannot be met, the funds become permanently inaccessible. This is why proper key management for each signer is critical.
Is Safe the same as Gnosis Safe?
Yes. Safe was originally called Gnosis Safe when it was a product of Gnosis Ltd. In 2022, it was spun out as an independent entity called Safe Ecosystem Foundation. The product, smart contracts, and functionality remained the same. The rebranding to Safe reflects its broader mission beyond the Gnosis ecosystem.
