Yes. An existing DAO or company treasury can migrate to a multisig at any time. In fact, this is how most treasuries end up on multisig in the first place.
Very few projects start with a multisig on day one. Early on, things move fast. One founder wallet. Maybe a hardware wallet. Maybe a trusted operator. That works until the value grows, more people get involved, or outside capital enters the picture. That is usually the moment teams realize a single wallet no longer makes sense.
Migrating later is normal. It is expected. And it is usually straightforward.
A multisig wallet created with platforms like Safe is a completely separate on chain address. You do not convert your existing wallet into a multisig. You create a new multisig and then move funds into it.
The migration itself is just a transfer. Funds are sent from the old treasury wallet to the new multisig address. From the blockchain’s perspective, there is nothing special happening. What changes is governance. Once the funds are inside the multisig, no single person can move them alone anymore.
Most mature teams do not migrate everything in one shot. They take a phased approach. First, they create the multisig and carefully verify the signers and approval threshold. Then they send a small test amount to confirm everything works as expected. Only after that do they move larger balances or long term reserves.
This gradual migration reduces risk and builds confidence across the team.
Another concern people raise is disruption. Will migration break operations? Usually not. Teams often keep a small operational balance in the original wallet for day to day expenses while moving long term or strategic funds into the multisig. Over time, more activity shifts into the multisig as processes mature.
For DAOs, migration often coincides with governance changes. The multisig becomes the execution layer for on chain or off chain votes. For companies, it usually aligns with board oversight, audits, or investor requirements. In both cases, multisig acts as a control layer, not a blocker.
There is no deadline for doing this. You can migrate at ten thousand dollars or at ten million. The only real difference is how painful the lesson is if something goes wrong before you do it.
The biggest mistake teams make is waiting too long because migration feels intimidating. In reality, staying on a single wallet while value grows is the riskier choice. Multisig migration is reversible, manageable, and well understood. Loss from a compromised single wallet is not.
The practical takeaway is simple. Starting without multisig is common. Staying without multisig once real value is involved is a decision you should be able to defend.
Multisig is not a launch feature. It is a maturity milestone.
