Safe multi-sig wallet DeFi teams how to use

Best Multi-Sig Wallet for DeFi Treasuries: Safe vs Squads vs Fireblocks

By Chanuka Geekiyanage Aug 13, 2026

A multi-sig wallet requires more than one signer to approve a transaction before funds move, and for a DeFi team, that decision determines whether a single compromised laptop can drain the treasury or not. Safe is the default choice for most EVM teams, but it is not the only option, and picking the wrong setup creates real problems: slow approvals that stall payroll, over-concentrated signer groups that recreate single-key risk, or a chain mismatch that leaves a team without multi-sig coverage at all. This guide compares Safe against the alternatives DeFi teams actually consider, walks through how to size an approval threshold, and flags the mistakes that turn a security tool into an operational bottleneck.

Why the Multi-Sig Choice Matters

Treasury losses rarely come from exotic hacks. They come from one signer holding too much power, a phishing link, or a wallet that never got upgraded after a team member left.

Learn everything about multi-sig wallets and when your team should set one up before comparing platforms, since the right timing depends on treasury size and team structure, not just security preference. A three-person project moving $50,000 has different needs than a DAO managing $50 million.

Safe vs the Alternatives

Safe (formerly Gnosis Safe) dominates EVM multi-sig because it is audited repeatedly, deployed as an on-chain smart contract, and supported by nearly every wallet and block explorer. It is not the only serious option, though, and the right choice depends on chain and team type.

· Safe works for any EVM chain and supports Modules and Guards for programmable permissions, like spending limits or automated recurring payments. The tradeoff is that it is EVM-only, so teams operating on Solana or other non-EVM chains need a different tool entirely.

· Squads Protocol is the equivalent standard on Solana, used by many Solana-native DAOs and protocols for treasury management and program upgrade authority. It benefits from Solana's low transaction costs, which matters for teams approving many small payments, but it has a smaller ecosystem of integrations than Safe.

· Fireblocks targets institutions and exchanges rather than DAOs. It combines MPC (multi-party computation) key management with policy engines and insurance options, but it is a paid enterprise product, not a free on-chain contract, so it suits funded companies more than community-run protocols.

Protocol	Strengths	Weaknesses	Best For
Safe	Audited, EVM-wide, Modules/Guards for automation	EVM-only, no native Solana support	DAOs and protocols on Ethereum, Base, Arbitrum, and other EVM chains
Squads Protocol	Low fees, Solana-native, used for program upgrade authority	Smaller ecosystem, Solana-only	Solana DAOs and protocol teams
Fireblocks	MPC custody, compliance tooling, insurance options	Paid enterprise product, less transparent than on-chain contracts	Funded companies, exchanges, market makers

How to Evaluate a Multi-Sig Setup

Start with three questions before choosing a platform: which chain holds the treasury, how many people should realistically hold signing power, and how fast does the team need transactions to clear. A protocol executing time-sensitive liquidations needs faster approval paths than a DAO paying quarterly grants.

Check the audit history next. Safe has been audited by multiple firms, including OpenZeppelin, and has years of mainnet history securing tens of billions in aggregate value, which matters more than marketing claims. A newer multi-sig tool with no audit trail is not worth the risk, regardless of its feature set.

Confirm recovery options last. A wallet that offers no path to replace a lost or compromised signer key turns one bad day into a permanent problem.

Choosing an Approval Threshold

The threshold is the number of signatures required out of total owners, and it is the single biggest lever a team controls. A 2-of-3 setup approves fast but tolerates less signer redundancy.

A 3-of-5 threshold is the most common starting point because it survives one signer going offline while still requiring real consensus. A 4-of-7 or higher threshold suits large DAOs where governance legitimacy matters as much as speed, since more signers reviewing a transaction reduces the odds of a rushed or malicious approval slipping through.

If You...	Recommended Threshold	Why
Are a 3-person early-stage project	2-of-3	Speed matters more than redundancy at this size
Manage a mid-size treasury ($1M-$50M)	3-of-5	Balances security with signer availability
Run a large DAO with public governance	4-of-7 or higher	Broader consensus reduces insider and rushed-approval risk
Need emergency pause capability	Separate lower-threshold Safe for emergency actions only	Isolates fast-response power from treasury funds

Common Mistakes DeFi Teams Make

Concentrating signers who work closely together defeats the point of a multi-sig, since a phishing campaign targeting one office or Discord group can compromise all of them at once. Teams should spread signers across different locations, devices, and social circles.

Skipping hardware wallets is the second most common mistake. Explore the comparison between hardware wallets and software wallets before assigning signer roles, because a software-only signer key is still a single point of failure even inside a multi-sig structure.

Letting stale signers keep access after they leave the team is the third. Regular permission audits catch this before it becomes a liability.

Risks and Tradeoffs

Multi-sig does not eliminate risk; it redistributes it. A malicious majority of signers can still drain a treasury, which is why threshold and signer selection matter more than the software itself.

Smart contract risk also applies. Safe's contracts are heavily audited, but any upgrade to Modules or Guards should go through the same review process as a protocol's own smart contracts, since a misconfigured Module can bypass the approval logic entirely.

Coordination lag is a real operational cost, not just an inconvenience. Teams moving funds during a live exploit need a pre-agreed emergency process, not a scramble to reach five people across time zones.

My Take

For most EVM DeFi teams, Safe is still the right default. It has the deepest audit history, the widest wallet and tooling support, and Modules that let teams automate routine payments without giving up multi-sig protection on large transfers.

I would only look elsewhere in two cases: a Solana-native team, where Squads is the better fit, or a funded company that needs compliance reporting and insurance, where Fireblocks earns its subscription cost. What Safe will not protect a team from is bad signer selection. A 3-of-5 Safe where four signers share an office is functionally closer to a 1-of-1 wallet than teams realize, so I'd rather see a smaller, more geographically distributed signer set than a large one that looks secure on paper.

Before moving real funds, run a small test transaction and confirm every signer can independently access their hardware wallet. Skipping that step is the most common way teams discover a broken setup during an actual emergency.

Conclusion

Safe remains the strongest default for EVM treasuries because of its audit history and ecosystem support, but the right choice depends on chain, team size, and how much speed the team is willing to trade for security. A 3-of-5 threshold with geographically distributed, hardware-wallet-backed signers covers most mid-size teams well, while larger DAOs should lean toward higher thresholds and Solana-native teams should evaluate Squads instead. Whatever platform a team picks, the setup only works if signer selection and recovery planning get as much attention as the software itself.

FAQs

1. Is Safe better than Squads for a DAO treasury?

Safe is the stronger choice for any EVM-based DAO because of its longer audit history and wider tooling support. Squads is the better choice if the treasury lives on Solana, since Safe does not support that chain.

2. What approval threshold should a small DeFi team start with?

Most teams under 10 people start with 3-of-5, which balances speed with redundancy if one signer is unavailable. Teams under five people sometimes use 2-of-3 for faster execution, accepting slightly less redundancy.

3. Can a multi-sig wallet be hacked?

A multi-sig cannot be drained by one compromised key, but it can be drained if a majority of signers are compromised or collude. This is why signer diversity and hardware wallet use matter as much as the threshold number itself.

4. Is Fireblocks worth the cost compared to Safe?

Fireblocks makes sense for funded companies and exchanges that need compliance reporting, insurance, and MPC key management beyond what an on-chain contract provides. For most DAOs and early-stage protocols, Safe's free, audited contract covers the same core security need without a subscription fee.

5. What is the biggest mistake teams make when setting up a multi-sig?

Choosing signers who are geographically or socially close together, which recreates single-point-of-failure risk even with a high threshold. The second most common mistake is skipping hardware wallets for individual signer keys.
