Unlocking secure hardware for MetaMask developers
Hot-wallet simplicity meets cold-wallet security for MetaMask-powered dapps and Snaps.
Use the CubeSigner Snap to manage EVM and non-EVM keys on behalf of your MetaMask end users. Programmatically request signatures, and your users’ keys sign server-side from within secure hardware—and stay safe from attackers.
Sign transactions while users’ keys stay safe inside secure hardware
Building dapps or Snaps means taking on the liability of managing your users’ keys, and a single mis-managed key can cost your users thousands of dollars—or cost your reputation. Unfortunately, if you’re using keys stored in the browser, those keys are exposed to sophisticated remote attackers who can exfiltrate browser data.
CubeSigner keeps your users' keys safe in server-side secure hardware as you programmatically sign transactions.
The CubeSigner Snap abstracts the complexity of key management to a simple set of API endpoints, so you can securely power your users' in-dapp or in-Snap transactions across many chains.
