Can I migrate my existing personal wallet to Safe?

Not directly. Safe is a smart contract, distinct from an EOA, and has its own address. You need to create a new Safe, then transfer assets from your personal wallet to the Safe's address. When transferring, use the deployed Safe's address as the receiver; the coins will enter the Safe and be governed by the multisig logic.

Does Safe support NFTs and any tokens?

Yes. Safe is a generic smart contract holder — it can hold ETH, ERC-20 tokens, ERC-721 NFTs, ERC-1155 tokens, and interact with any other smart contract. You can use Safe to stake, swap, lend, trade NFTs — any action you can take with a regular EOA wallet.

How much does it cost to use Safe?

The Safe Foundation does not charge a direct fee. You only pay the gas fee for each transaction (deploy, propose, execute). On L2s (Arbitrum, Base, Optimism), the total cost is ~$1-5 per transaction. On Ethereum mainnet, it's ~$50-200 per transaction. Some advanced modules (Safe{Pass}, Safe{Wallet} subscription) have their own fees, but most users do not need them.

Can I change the owners and threshold after setup?

Yes. Any change (adding or removing an owner, changing the threshold) is an on-chain transaction requiring the threshold of N owners to sign. For example, a 3-of-5 Safe wanting to add a new owner needs 3/5 owners to sign the 'addOwner' proposal. This is a good mechanism — no single individual can secretly alter the configuration.

Is Safe at risk if an owner's private key is compromised?

There is a risk, but it is limited. If one owner is hacked (1 key compromised) in a 3-of-5 setup, the hacker cannot withdraw funds because they need 2 more signatures. However, the hacker could propose a transaction and wait for an opportunity. Mitigation: as soon as a key compromise is detected, the remaining owners should propose removing that owner and adding a new owner with a clean key.

I'm a solo founder, do I need Safe?

It depends on the fund size. If the fund is under 100 million VND, Safe might be overkill — the gas costs and overhead outweigh the benefits. If the fund is over 500 million VND, I recommend Safe even for solo founders. You can set up a 2-of-3 Safe with 2 of your own wallets (e.g., Ledger + MetaMask on different devices) + 1 trusted backup. This protects against single device failure without needing an external party.

The 2025-2026 period has seen an explosion of Vietnamese Web3 groups — from small DAOs of a few people, to community funds managing billions of VND, to DAO investment clubs with dozens of members. All face a common problem: how to manage a shared fund securely without trusting a single individual to hold the private key? The industry standard answer is the multisig wallet — and Safe (formerly Gnosis Safe) is the most widely used solution, currently securing over $100 billion in assets globally. This article provides a detailed guide for Vietnamese teams to set up Safe, choose the right N-of-M threshold, and implement 7 best practices drawn from real-world experience.
