## Pyth Lazer Aptos Contract

This package is built using the Move language and Aptos framework.

`PythLazer` is an Aptos contract that allows consumers to easily verify Pyth Lazer updates for use on-chain.

### Build, test, deploy

```

Deploy to the network configured in your aptos profile:

Invoke deployed contract functions on-chain:

```shell
