Polysign
Polysign is a prototype web3 implementation of esignature collection built on Polygon smart contracts and IPFS.
Enables Docusign-like capabilities / use-cases using web3 infrastructure.
Built for the Road to Web3 hackathon 2022.
- Polysign enables anyone to create and collect esignature against documents without a vendor agreement. A polygon smart contract is deployed for each request.
- Each packet of documents for esignature is made accessible at an IPFS url.
- When the esignature is completed, an NFT is generated that links both the signer's signature and the documents being agreed on.
- Hosted documents and the request are immutable.
- Smart contract deployed on Polygon which marks the progress/fulfillment of the esignature request. The contract can only be marked completed by the designated signer address at time of final signature.
- View history of requests and completed esignatures using the covalent chain history API directly from the app.
- An individual in the context of the Polysign application is the pairing of a canvas (handwritten) signature and wallet signature/address.
- Covalent: Enables in-app history queries of past esignature requests and fulfillment for a given polygon address.
- NFTPort: Generation of the esignature record / proof. Attaches the final esignature/agreement to an NFT and saves a link to it in the smart contract.
- Moralis: Serves as main backend for the app - uses IPFS to enable support/hosting of the document packets for each request.
- Polygon: In-app deployment of the request smart contract and marked completed upon completion of the each request based on receival of signer's signature. A new Polygon contract is deployed for each new esignature request.
- Sequence: Wallet for facilitating polygon and submitting final sign request. Deployment can toggle between sequence wallet or metamask.
This project is a hackathon prototype and would require additional work / deployment to be production ready.
To run/demo the project locally, Polysign requires the following environment variables.
REACT_APP_MORALIS_ID={YOUR_MORALIS_APP_ID} # Moralis app id
REACT_APP_MORALIS_SERVER={YOUR_MORALIS_SERVER_URL} # Moralis server url
REACT_APP_COVALENT_KEY={YOUR_COVALENT_API_KEY} # Covalent key for the history page.
REACT_APP_NFT_PORT_KEY={YOUR_NFT_PORT_API_KEY} # NFT port api key for receipt creation.
REACT_APP_USE_SEQUENCE={TRUE_OR_FALSE (optional)} # Indicates whether to use sequence or metamask as primary wallet provider.
After declaring the above environment variables, use the below command to start the project:
yarn yarn start
Recompiling contract:
cd contracts; npx hardhat compile
