Setting up Third-Party Custody

As discussed previously, the services your custodian offers, and your experience working with them, is one of the most important parts of the MetaMask Institutional platform. That's why one of the first steps in getting MMI set up is choosing one of our custodial partners; reach out to us if you need help in that process.

The procedure, in general, will involve getting signed up with a custodian, and configuring the corresponding profiles, accounts, and permissions that you need for your specific business needs. Once you've done that, you'll need to import the private keys from your custodial accounts into MMI so that you can use them with all the DeFi tools you wish to.
