Run every Safe from one place.
Connect the Safes you have, create new ones, and upgrade them for bank payments. Fully compatible with app.safe.global, so every signer can sign from either.
Manage every Safe, or create one
Three ways in, from the same place you add every other account.
- Auto-detect. Connect your wallet and every Safe it signs for is listed.
- Paste an address. The owners and threshold are read from the chain.
- Create a new Safe on the chain you pick, with the owners and threshold you set.
Sign here or on app.safe.global
A payment proposed in Mezzanine sits in the Safe's own queue, and a signature from either site counts toward the same threshold. Every queued action links straight to it on app.safe.global.
Your Safe stays a standard Safe: fully compatible and fully portable. Nothing about it depends on Mezzanine, and your signers can keep using the tools they already trust.
Try it Collect two signatures, one from each place.

Everything a Safe needs, day to day
See your money
Every asset the Safe holds, next to your banks, wallets and other accounts.
Owners and proposers
Add or remove owners, change how many signatures a payment needs, and let proposers queue payments they cannot sign.
Sign and run
See what is waiting and who has signed, then run it once the threshold is met. Withdraw a proposal for free, or cancel it on chain.
History
Every payment, swap and settings change the Safe has made, each linked to the chain explorer.
Changing the owners or the signatures needed is a transaction like any other: it takes the next slot in the queue and needs the Safe's own signatures.
Your signers hold the keys.
The software never holds a key to your Safe. It proposes transactions and collects signatures, and the Safe's owners and threshold decide what runs. Anyone can watch a Safe; only its owners can sign.
Self-custody doesn't have to be the only option, but it should always be one.
Mezzanine is backed by the Safe Foundation.
Out of one person's wallet
Company money often starts in a founder's MetaMask, on a hardware wallet, or on an exchange. Move it somewhere no one person controls.
- Create a Safe with the owners and the number of signatures you choose.
- Connect the wallet the money sits in, and send it to the Safe with an Internal Transfer. The move is on the record, as the company's own money changing accounts.
- From an exchange, withdraw to the Safe's address on the exchange itself. An exchange account is tracked, never sent from.
From then on, nothing leaves without the Safe's signatures and your approval rules.
Upgrade it for banks
Give a Safe its own bank details, so wires arrive as USDC, and pay bank accounts straight from it in dollars.
