Autonomys Auto SDK Monorepo

Overview

The Autonomys Auto SDK is a powerful toolkit designed to empower developers to seamlessly integrate with the Autonomys Network. It enables interaction through familiar programming languages like TypeScript, without needing to delve into the complexities of blockchain or smart contracts. The SDK provides simple APIs for issuing and verifying Auto IDs, interacting with the consensus layer, handling data uploads, and managing payments using Auto Coin.

Packages

This monorepo contains multiple packages, each serving a specific purpose. All packages are published to npm under the @autonomys scope:

• @autonomys/auto-utils: Core utility functions for interacting with the Autonomys Network.
• @autonomys/auto-consensus: Functions for interacting with the Consensus Layer.
• @autonomys/auto-drive: Tools for preparing and managing data for on-chain storage.
• @autonomys/auto-id: Functions for generating, renewing, and revoking Decentralized Identities (Auto IDs).

Installation

Requirements

• Node.js (version 14 or higher)
• Yarn or npm

Installation

Install the packages you need via npm or yarn. For example, to install @autonomys/auto-utils and @autonomys/auto-consensus:

# Using npm
npm install @autonomys/auto-utils @autonomys/auto-consensus

# Using yarn
yarn add @autonomys/auto-utils @autonomys/auto-consensus

Usage Examples

Below are small, reproducible examples demonstrating how to use each package. Packages are grouped where it makes sense to show how they interact.

1. Using @autonomys/auto-utils and @autonomys/auto-consensus

These two packages work hand-in-hand to allow you to interact with the Autonomys Network and perform actions like checking balances and transferring funds.

Activate a Wallet and Check Balance

// Import necessary functions
import { activateWallet } from '@autonomys/auto-utils'
import { balance } from '@autonomys/auto-consensus'
;(async () => {
  // Activate a wallet using a mnemonic phrase
  const { api, accounts } = await activateWallet({
    mnemonic: 'your mnemonic phrase here', // Replace with your mnemonic
    networkId: 'gemini-3h', // Optional: specify the network ID
  })

  const account = accounts[0]
  console.log(`Connected with account address: ${account.address}`)

  // Check the account balance
  const accountBalance = await balance(api, account.address)
  console.log(`Account balance: ${accountBalance.free}`)

  // Disconnect when done
  await api.disconnect()
})()

Transfer Funds Between Accounts

// Import necessary functions
import { activateWallet } from '@autonomys/auto-utils'
import { transfer } from '@autonomys/auto-consensus'
;(async () => {
  // Activate sender's wallet
  const senderWallet = await activateWallet({
    mnemonic: 'sender mnemonic phrase', // Replace with sender's mnemonic
  })
  const sender = senderWallet.accounts[0]

  // Activate receiver's wallet
  const receiverWallet = await activateWallet({
    mnemonic: 'receiver mnemonic phrase', // Replace with receiver's mnemonic
  })
  const receiver = receiverWallet.accounts[0]

  // Transfer 1 ATC from sender to receiver
  const amount = 1 // Amount in ATC
  const transferTx = await transfer(senderWallet.api, receiver.address, amount)

  // Sign and send the transaction
  await transferTx.signAndSend(sender, ({ status, txHash, events }) => {
    if (status.isInBlock) {
      console.log(`Transaction included at blockHash ${status.asInBlock}`)
      console.log(`Transaction hash: ${txHash}`)
    } else if (status.isFinalized) {
      console.log(`Transaction finalized at blockHash ${status.asFinalized}`)
    }
  })

  // Disconnect when done
  await senderWallet.api.disconnect()
  await receiverWallet.api.disconnect()
})()

2. Using @autonomys/auto-drive

The @autonomys/auto-drive package provides utilities for creating and managing IPLD DAGs (InterPlanetary Linked Data Directed Acyclic Graphs) for files and folders.

Creating an IPLD DAG from a File

// Import necessary functions
import { createFileIPLDDag } from '@autonomys/auto-drive'
import fs from 'fs'

const fileBuffer = fs.readFileSync('path/to/your/file.txt')

// Create an IPLD DAG from the file data
const dag = createFileIPLDDag(fileBuffer, 'file.txt')

console.log(`Created DAG with head CID: ${dag.headCID}`)

// The 'nodes' map contains all nodes in the DAG
console.log(`Total nodes in DAG: ${dag.nodes.size}`)

Creating an IPLD DAG from a Folder

// Import necessary functions
import { createFolderIPLDDag } from '@autonomys/auto-drive'
import { CID } from 'multiformats'
import fs from 'fs'
import path from 'path'

// Function to read files from a directory and create CIDs
function getFilesCIDs(directoryPath: string): CID[] {
  const fileNames = fs.readdirSync(directoryPath)
  const cids: CID[] = []

  fileNames.forEach((fileName) => {
    const filePath = path.join(directoryPath, fileName)
    const fileBuffer = fs.readFileSync(filePath)
    const fileDag = createFileIPLDDag(fileBuffer, fileName)
    cids.push(fileDag.headCID)
  })

  return cids
}

const directoryPath = 'path/to/your/folder'
const childCIDs = getFilesCIDs(directoryPath)
const folderName = 'my-folder'
const folderSize = childCIDs.length

// Create an IPLD DAG for the folder
const folderDag = createFolderIPLDDag(childCIDs, folderName, folderSize)

console.log(`Created folder DAG with head CID: ${folderDag.headCID}`)

3. Using @autonomys/auto-id

The @autonomys/auto-id package provides functionalities for managing certificates, authenticating users, and integrating Zero-Knowledge Proofs (ZKPs) on the Autonomys Network.

Authenticate a User with Auto ID

// Import necessary functions
import { authenticateAutoIdUser } from '@autonomys/auto-id'
import { activate } from '@autonomys/auto-utils'

;(async () => {
  // Activate the network API
  const api = await activate()

  // User's Auto ID
  const autoId = 'user-auto-id' // Replace with the user's Auto ID

  // Challenge message that the user needs to sign
  const challengeMessage = 'Please sign this message to authenticate.'
  const challenge = new TextEncoder().encode(challengeMessage)

  // Assume the user provides the signature
  const signature = new Uint8Array([...]) // User's signature as Uint8Array

  // Authenticate the user
  const isAuthenticated = await authenticateAutoIdUser(api, autoId, challenge, signature)

  if (isAuthenticated) {
    console.log('User authenticated successfully.')
  } else {
    console.log('Authentication failed.')
  }

  // Disconnect when done
  await api.disconnect()
})()

Self-Issuing a Certificate

// Import necessary functions
import { selfIssueCertificate } from '@autonomys/auto-id'
import { generateKeyPair } from '@autonomys/auto-utils'
;(async () => {
  // Generate a key pair
  const keyPair = await generateKeyPair()

  // Subject name for the certificate
  const subjectName = 'CN=User Name' // Replace with appropriate subject

  // Generate a self-signed certificate
  const certificate = await selfIssueCertificate(subjectName, keyPair)

  console.log('Certificate created:', certificate)
})()
