  • 120 sec updates frequency check will be applied
  • 120 sec oracle update frequency will be added for each asset

DELIVERY INFORMATION

Delivery Method Oracle on Moonbase Alpha
Is testnet deployment required? Yes
Delivery Estimate 10 days

Please deploy an oracle with above assets on Moonbeam mainnet in addition to moonbeam testnet

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:
Moonbeam
Moonbeam Alpha

You can query for assets by calling the read function getValue() with parameters such as “ARB/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 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:

Moonbeam: 0xcbe6fd95b1fb97ee38d5260340771a1a4bff15cd
Moonbeam Alpha: 0x519a83db1d93cfdb612864dd22658381fb19f5f2

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.

Please add to this oracle the following assets:

Asset Ticker Asset Blockchain
CELO Celo
cUSD Celo
KAVA Kava

The updates have been deployed to both oracles (Moonbeam and Moonbeam Alpha).
