Pyth Network
Consume Pyth Network prices on Aptos
Aptos contracts can update and fetch Pyth prices using the Pyth Aptos package, which has been deployed on Mainnet. The documented source code can be found here.
Use cases for Pyth with Econia
The core variable utilized by decentralized derivative exchanges, traditionally perpetual futures, is the oracle index price, which powers the exchange’s funding rate mechanism and liquidation engine. Without a reliable and secure oracle provider, innovative on-chain platforms of this nature cannot be built.
By leveraging Pyth’s price data feeds to build these exchange components, and combining them with Econia’s hyper-parallelized order book to match and settle trades, developers can build a high performance perpetual derivatives trading platform.

Updating price feeds
The mechanism by which Pyth price feeds are updated on Aptos is explained here.
The pyth-aptos-js package can be used to fetch price feed update data, which can then be passed to the pyth::update_price on-chain function.
Examples
- Minimal on-chain contract which updates and returns the Pyth BTC/USD price.
- Full-stack React app and on-chain contract which uses the
pyth-aptos-jspackage to update the price used by the contract. - In-depth explanation of how Pyth works on Aptos and how to integrate Pyth data in your application.
Networks
Pyth is currently deployed on Aptos Mainnet and Testnet.
Addresses
When deploying contracts using Pyth, the named addresses pyth, wormhole and deployer need to be defined at compile time. These addresses are the same across both Testnet and Mainnet.
| Named Address | Value |
|---|---|
pyth | 0x7e783b349d3e89cf5931af376ebeadbfab855b3fa239b7ada8f5a92fbea6b387 |
wormhole | 0x5bc11445584a763c1fa7ed39081f1b920954da14e04b32440cba863d03e19625 |
deployer | 0xb31e712b26fd295357355f6845e77c888298636609e93bc9b05f0f604049f434 |
deployer and wormhole are implementation details of the Pyth contract: you will not need to interact with these.
