- Polysign enables anyone to create and collect esignature against documents without a vendor agreement. - 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.

How it's made

View the full detail here: Starts with a react template for the app with routes for creating the request, esigning, and viewing history for polygon addresses. Sponsors each play a key piece in fulfilling the signature requests. - 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/fulfillment of the each request signer's signature. - Sequence: Wallet for facilitating polygon and submitting final sign request. Deployment can toggle between sequence wallet or metamask.
