DAppNode has been an important part of Ethereum infrastucture since 2018 by allowing non-technical users to run their own nodes and validators.

Because we are in the trenches with our users, solo stakers and home Nod eRunners, we have direct experience with the problems they face. In this quest for better User Experience in the web3 ecosystem, we've created a wealth of Open Source tools that any project can use.

Keymanger API: We coordinated client implementers and stakeholders to standardize the way keys are managed between different pieces of software.
Keymanager UI (https://github.com/dappnode/eth2-keymanager-frontend) - a front-end that uses the Keymanager API (https://ethereum.github.io/keymanager-APIs/) to connect to any validator implementation and web3signer.
