How to access data
Accessing the oracle on-chain (Solidity)
To consume price data, you’ll need to invoke thegetValue
method on the oracle contract which you can access through the DIA Oracle library or the interface.
Below is an example of a contract consuming data from the oracle on Hydration testnet using the IDIAOracleV2 interface. If you pass BTC/USD
as the key, it will return the most recent price of BTC in USD with 8 decimal places (e.g. 9601458065403 is $96,014.58065403) along with the Unix timestamp of the last price update.
Adapter contracts
To consume price data from our oracle, you can use the adapter smart contract located at the adapter address for each asset. This will allow you to access the same methods on theAggregatorV3Interface
such as getRoundData
& latestRoundData
. You can learn more here.
