Document Store
The Document Store repository contains both the smart contract code for document store (in /contracts
) as well as the node package for using this library (in /src
).
Prerequisite
- Node (optionally, use nvm to manage node version)
- Node version 18 onwards.
Installation
npm i @tradetrust-tt/document-store
Usage
To use the package, you will need to provide your own Web3 provider or signer (if you are writing to the blockchain).
Deploy new document store
import { deployAndWait } from "@tradetrust-tt/document-store";
const documentStore = await deployAndWait("My Document Store", signer).then(console.log);
Connect to existing document store
import { connect } from "@tradetrust-tt/document-store";
const documentStore = await connect("0x4077534e82c97be03a07fb10f5c853d2bc7161fb", providerOrSigner);
Interact with document store
const issueMerkleRoot = async () => {
const documentStore = connect("0x4077534e82c97be03a07fb10f5c853d2bc7161fb", signer);
const tx = await documentStore.issue("0x7fe0b58ed760804eb7118988637693c4351613be327b56527e55bcd0a8d170d7");
const receipt = await tx.wait();
console.log(receipt);
const isIssued = await instance.isIssued("0x7fe0b58ed760804eb7118988637693c4351613be327b56527e55bcd0a8d170d7");
console.log(isIssued);
};

Provider & Signer
Different ways to get provider or signer:
import { Wallet, providers, getDefaultProvider } from "ethers";
// Providers
const mainnetProvider = getDefaultProvider();
const goerliProvider = getDefaultProvider("goerli");
const metamaskProvider = new providers.Web3Provider(web3.currentProvider); // Will change network automatically
// Signer
const signerFromPrivateKey = new Wallet("YOUR-PRIVATE-KEY-HERE", provider);
const signerFromEncryptedJson = Wallet.fromEncryptedJson(json, password);
signerFromEncryptedJson.connect(provider);
const signerFromMnemonic = Wallet.fromMnemonic("MNEMONIC-HERE");
signerFromMnemonic.connect(provider);
Setup
npm install
npm lint
npm test
npm truffle <command>
Contract Benchmark
A benchmark is provided to show the different transaction cost of the different variants of the document store.
npm run benchmark
