What is Ethsign?

Ethsign, part of the Dapp tools suite distribution, makes use of secure/offline key storage to sign Ethereum transactions. Developers can offer secure smart contract signing to their DApps, although they'd have to install the entire suite and only call those which they require. The platform is built with Nix, and contributions from the community are encouraged.
