Grant Proposal EthSign

Name of Project / DAO / Company


Application type

DAO Governance Tool, dAPP

Proposal overview

EthSign is built upon Web3 infrastructure that has just become mature over the past few years: Decentralized Identity, smart contract platforms and decentralized storage networks. EthSign‘s mission is to become the underlying infrastructure and platform for multi-party collaboration such as DAO proposal execution (investment, portfolio lock-up management), credit lending, crowdfunding, etc.

We currently have two offerings:

  • EthSign 3.0 (PDF Signing) is a completely serverless website (, statically hosted on IPFS + Arweave and runs entirely within the user’s browser. provides the same functionality and UX as a Web 2.0 electronic agreement signing platform, while leveraging the power of blockchains to enhance transparency and security.

  • EthSign Smart Agreements (ESA) is our upcoming customizable and extendable framework that truly realizes the vision for “smart contracts”. ESA enables electronic agreements to have tighter binding properties by enforcing its execution using smart contracts in addition to or in place of existing legal enforcement. Powered by Chainlink Oracles and Keepers, one use case of ESA is smart escrow triggered by on-chain and/or off-chain conditions.
