How to Route Bridge Proceeds to a Multisig Treasury

A protocol can route bridge proceeds to a 3-of-5 multisig treasury, so three of five designated signers must approve a later spend. The 3-of-5 setup is an example; the protocol chooses its own owners and approval threshold.

The basic idea is to make the treasury the receiving address on the destination chain. If the bridge transfer also involves a token swap, the mantle bridge guide covers whether to swap before or after crossing and the fee trade-off.

How do bridge proceeds reach a multisig?

They reach it when the destination-side transfer sends the assets to the multisig’s address. A bridge may lock tokens on one chain and release them on another, or burn tokens on the source chain and mint them on the destination chain. In either case, the team must set the receiving address correctly.

That address can be a multisig smart account, such as a Safe, if the bridge supports sending to it. Some routes instead deliver funds to the connected wallet or another fixed recipient. Check the bridge’s recipient field and confirm the account can receive the token on the destination network before sending funds.

“Proceeds” can mean the bridged token itself or the result of a swap along the route. Those are different outcomes. A treasury that expects a stablecoin, for example, may receive a different asset if the route only transfers the original token.

What can the multisig control after the transfer?

A multisig holds assets at a shared address, and a set number of its owners must approve a transaction before it executes. If a treasury uses a 3-of-5 threshold, any three of its five owners must approve a spend. The bridge transfer does not spend those funds; it delivers them to an account controlled by that approval setup.

This separates receipt from spending. A single operator may initiate the bridge transfer, while the destination treasury’s signers control any later move. The trade-off is that sending to the wrong address or network can be difficult to fix, and a transfer can arrive in a token the treasury did not plan to manage.

What should a team check before sending?

Check the receiving chain, the exact treasury address, the token being delivered and any swap built into the route. Then confirm the multisig is deployed and usable on that chain, and that its owners can review and approve transactions there.

• Copy the treasury address from a trusted source and verify the full address.
• Confirm the bridge’s recipient field accepts a contract account.
• Check whether the route transfers, swaps or both, and which token should arrive.
• For a large transfer, consider a small test and verify the received balance first.

A direct transfer is simpler when the bridge can pay the multisig in the token the treasury needs. An extra swap or intermediary step can add fees and another point where the route may not match the team’s expectation. Choose the shortest route that delivers the right asset to the right account.

For the next transfer, watch the bridge’s completion status and the multisig’s balance on the destination chain. Treat the treasury as funded only after the expected token appears at the correct address.
