Protocol: DFX Finance
Integration: DFX is an Ethereum-based decentralized exchange protocol with a dynamically bonding curve optimized for fiat-backed stablecoins using real-world FX price feeds.
The following assets will be included in the Oracle:
|Asset Markets Overview
|NGN Asset Information
|NGN is the symbol representing the Nigerian Naira, the native currency of Nigeria.
- Moving Average Price with Interquartile Range (MAIR) will be used to calculate the price for the assets. Learn more about it here
- 0.5% deviation threshold for updates trigger will be applied for each asset
- 30min time window for trades aggregation will be applied for each asset
- 24-hour update frequency will be added for each asset
|Oracle on Ethereum
|Is testnet deployment required?
Thank you for requesting a data feed via DIA CDR. We confirm the CDR specifications were requested correctly. Find the oracle information below:
The oracle is deployed and can be accessed here.
You can query for assets by calling the read function getValue() with parameters such as “NGN/USD”. It will return two values:
- The price of the asset queried with 8 decimals
- 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.
Each deployed oracle 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: 0xf1c1bc28a6447386e1e6a31e472d176ac57dda5f
You can view the markets included for each feed by pressing on a link to DIA App in the deployed assets list:
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.
Amendment: Please change delivery method to Polygon instead of Ethereum
