Unified interface for interacting with TradeTrust's various services. This library contains a set of modules.

Module	Description
Verify	Verify TradeTrust issued document
Utils	Provide utility methods for TradeTrust functionalities

Installation

npm i @tradetrust-tt/tradetrust-core

Verify

verify allows you to verify issued document programmatically. After verification, use isValid method to answer some questions:

Has the document been tampered with ?
Is the issuance state of the document valid ?
Is the document issuer identity valid ? (see identity proof)

Document can be either verifiable document or transferrable record which follows TradeTrust document schema

// verify document using network name
import { verify, isValid } from '@tradetrust-tt/tradetrust-core/verify'
let document = {
    // your tradetrust document
}
const fragments = await verify(document, {
    network: 'sepolia', // can also provide other networks such as homestead
})
console.log(isValid(fragments))

// verify document using provider
import { ethers } from 'ethers'
import { utils } from '@tradetrust-tt/tt-verify'

const providerOptions = {
    // modify your provider options accordingly
    network: 'sepolia',
    providerType: 'infura',
    apiKey: 'abdfddsfe23232',
}
const provider = utils.generateProvider(providerOptions)

let document = {
    // your tradetrust document
}
const fragments = await verify(document, { provider })
console.log(isValid(fragments))

Utils

This module provides utility methods that supports the shared functionalities for other TradeTrust modules.

InterpretFragments

interpretFragments allows you to extract out the verified results from the fragments.

import {interpretFragments} from '@tradetrust-tt/tradetrust-core/utils`;

const fragments = await verify(document, {
            network: 'sepolia',
});

const {hasValid, issuedValid, identityValid} = interpretFragments(fragments);
console.log({hasValid, issuedValid, identityValid});
