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, too.
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.
Give a Safe its own bank details.
Let wires arrive as USDC, and pay from Safes to bank accounts in dollars.

Sign here or on app.safe.global.
Safe and Mezzanine are fully compatible, so a signature from either site counts toward the same threshold. Your Safe stays yours, and your signers can use whichever platform fits their needs.

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.
Professionalize company crypto management.
Company money shouldn't depend on the founder's MetaMask, hardware wallet, or exchange login. Mezzanine gives your team a simple system for permissions, structured access, and oversight on company funds.
- 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.
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.
