Non-custodial service provider

At MIDL.dev, we help you stake your cryptocurrency. We are a non-custodial staking-as-a-service company, which means that you hold your keys.

We will never ask you for your keys.

How it works

You maintain a signing device in a location of your choice. It is a small computer, connected to a Ledger hardware wallet which holds your signing keys. Two batteries ensure continuity of operations even in case of power loss.

The signing operations are simple enough that the physical setup remains relatively low maintenance. You may have to upgrade the firmware on the Ledger once in a while, but that is it. Everything else, including protocol upgrades, is handled by us.

We ship you the signing computers and batteries. Plug them in your closet, hidden behind the wi-fi router, or in a skunkworks collocation somewhere.

When turned on, the devices securely establish a connection to our infrastructure. When your turn comes, an message is tunneled to the signer, which signs it. It is then sent back for our infrastructure to broadcast it to the network.

The signers themselves are being monitored: if we lose touch with them, you will receive an alert email.

The signer operating system is fully open source and auditable.

Supported hardware wallets

We support Ledger Nano S, Ledger Nano S plus, and Yubikey.

Optional - set up your own

Our remote signers are best-in-class - reliable, redundant, and secure. But if you want to set up your own, we can assist !
