Pyth is an Oracle that offers on-chain low-latency market data from institutional sources. This means you can use prices from real-life assets in your Solana programs.
The price for each asset will be represented inside of a Solana account. We call those accounts price feeds.
For example, the price feed for SOL/USD on mainnet is represented on this account address: H6ARHf6YXhGYeQfUzQNGk6rDNnLBQKrenN712K4AQJEG.
You can find more of these price feeds here.
To use such a price feed, you need to pass its account into your instructions context.
You can get an asset's information by reading the account's data. The feed will consist of:
- A price
- A confidence interval
- An exponent
