True Network SDK

True Network provides the easy-to-use infrastructure for building blockchain-based reputation systems for the internet.

This SDK:

• You can use in NEXT.JS / Node.JS
• You can use to give on-chain attestations to users
• You can write & deploy the algorithms to True Network's Testnet
• Connect to the True Network Nodes (Testnet / Mainnet)

About Testnet

True Network launched it's testnet in the end of April 2024, named Raman Network (named after Great Indian Scientist: C.V. Raman).

It has 3 main pallets from the True Network's Node (repository):

• Issuer (Registering Issuer / dApp On-Chain)
• Credentials (Creating & storing new schemas and Issuing Attestations)
• Algorithms (Storing wasm file for the algorithm & running to get reputaiton score)

Alice account is pre-funded with some test tokens.

Explore the Example Usage

We have create a simple example usage for on-chain attestation, here.

This is a simple nodejs app, that is created using the True Network CLI and it gives on-chain attestation to user for progress in a game.

SDK Installation

Install it as dependency:

 yarn add @truenetworkio/sdk

Use the package to create a new TrueApi instance like this:

  import { TrueApi } from '@truenetworkio/sdk'

  const setup = async (): TrueApi => {
    const trueApi = await TrueApi.create('//Alice')

    // Set issuer.
    trueApi.setIssuer('issuerHash')

    return trueApi;
  }

Using CLI for faster development

True Network has created a CLI tool for creating a project structure for on-chain attestations & creating an keypair in-built in the config.

Installing CLI:

 npm install -g reputation-cli

Init a new True Network Project

Inside any existing nodejs + typescript project, run:

 reputation-cli init

It will ask a few questions like Issuer Name, existing keypair, etc. and will create a new config file in the true-network directory inside project.

Register Issuer On-Chain

Run the following code to register issuer:

 reputation-cli regsiter

Make sure you have some testnet tokens in the newly created account, else fund it from Alice acount.

Fetching the True Network Instance

Now you can just import the getTrueNetworkInstance method from the 'true-network' directory to get the instance.

 const trueApi = await getTrueNetworkInstance()
