A TypeScript library enabling you to explore the Data Economy. It is built on top of ocean.js and offers feature complete, automated interactions with any Ocean Protocol ecosystem.

Overview

nautilus addresses many common pain points faced by developers interacting with the data economy by offering a range of features enhancing productivity and efficiency. You will find a quick introduction on this page to get you setup with the Data Economy TypeScript Toolkit.

Quick Start

1. Setup your Signer

Firstly, create the signer you want to use with your nautilus instance. nautilus uses the ethers.js Signer. You can read more about possible configurations in the official documentation.

import { Wallet, providers } from 'ethers'
import { Nautilus } from '@deltadao/nautilus'

const provider = new providers.JsonRpcProvider('https://rpc.dev.pontus-x.eu') 
const signer = new Wallet('0x...', provider) 

In this example we create an ethers Wallet from a given private key and connect to a RPC provider of our choice.

2. Setup the nautilus instance

Now that you have a Signer set up, you can use it to bootstrap your nautilus client instance.

import { Wallet, providers } from 'ethers'
import { Nautilus } from '@deltadao/nautilus'

const provider = new providers.JsonRpcProvider('https://rpc.dev.pontus-x.eu')
const signer = new Wallet('0x...', provider)

const nautilus = await Nautilus.create(signer) 

Note, that we use the previously created Wallet and pass it to Nautilus to create the instance with this signer.

3. Interact with the data economy

With the client instance bootstrapped you can now trigger any transactions or access calls supported by OceanProtocol.

import { Wallet, providers } from 'ethers'
import { Nautilus } from '@deltadao/nautilus'

const provider = new providers.JsonRpcProvider('https://rpc.dev.pontus-x.eu')
const signer = new Wallet('0x...', provider)

const nautilus = await Nautilus.create(signer)

const accessUrl = await nautilus.access({ assetDid: 'did:op:12345'}) 
const data = await fetch(accessUrl) 

In this example we construct a one-time accessUrl and can then use it to fetch the data associated with the respective data service.
