Neurolanche X Labs | Token Price Feed

INTRODUCTION

Protocol: Neurolanche X Labs

Website: https://www.neurolanche.com/

Integration: Price Feed

Use case: The Price Feed Oracle will be used to fetch the ASTR token price to get the price dynamically.

Blockchain: Astar EVM (Parachain)

REQUEST INFORMATION

Assets

Following assets will be included in the Oracle:

Asset Ticker Asset Blockchain Asset Address Asset Markets Overview Comments
ASTR Astar 0x0000000000000000000000000000000000000000 ASTR Asset Information

Methodology

Select the methodologies that will define the feeds:

  • Moving Average Price with Interquartile Range (MAIR) will be used to calculate the price for the assets. Learn more about it here:
  • .5% deviation threshold for updates trigger will be applied for each asset:
  • 120 secs update frequency check will be applied.

DELIVERY INFORMATION

Select if the feed should be delivered on-chain via oracle and if so, which network:

  • Delivery method: Oracle on Astar-EVM
  • Testnet required: No

Thank you for requesting a data feed via DIA CDR. We confirm the CDR specifications were requested correctly. Find the oracle information below:

Oracle

The oracle is deployed and can be accessed here.

You can query for assets by calling the read function getValue() with parameters such as “ASTR/USD”. It will return two values:

  1. The price of the asset queried with 8 decimals
  2. The unix timestamp of the last update

You can see Solidity and Vyper code integration examples here or use a dedicated DIA oracles integration library described in detail here.

Funding

Each deployed oracle contract has a separate gas wallet which is the only entity allowed to update oracle values based on selected parameters. To find out more information on how it works, visit the following link.

Please make sure to top up the gas wallet, as we only put in some gas to deploy and start the oracle.

Gas Wallet address: 0x0687d29675595139479d2fD7a32b75Db91741f81

Markets

You can view the markets included for each feed by pressing on a link to DIA App in the deployed assets list:

  1. Astar-0x0000000000000000000000000000000000000000

Note: DIA uses Blockchain-Address querying formatting to ensure asset selection precision (token symbols might duplicate)

You can also query current asset prices and find other market information on the asset by using the DIA API as described here.
