## Pyth Lazer Sui Contract
2+
3+
`pyth_lazer` is a Sui package that allows consumers to easily parse and verify cryptographically signed price feed data from the Pyth Network's high-frequency Lazer protocol for use on-chain.
4+
5+
This package is built using the Move language and Sui framework.
6+
7+
### Build, test, deploy
8+
9+
Install Sui CLI and build the project:
10+
11+
```shell
12+
brew install sui
13+
sui move build
14+
```
15+
16+
Run tests:
17+
18+
```shell
19+
sui move test
20+
sui move test test_parse_and_verify_le_ecdsa_update # run a specific test
21+
```
22+
23+
Deploy:
