+# Example Full-Stack App: 1$ Mint
+
+The example contract is deployed at : `0x19f8503273cdb5aa93ffe4539277684615242127aa2e65ef91424136a316c9c7`
+
+The goal of this contract is managing an NFT mint where the mint is paid in native currency but the cost of one NFT is always 1$.
+This example is intended to be run on Aptos testnet because it depends on Pyth and Wormhole existing onchain.
+
+### Important files :
+
+- `./sources/minting.move` has the smart contract logic (the code that will run onchain)
+- `./app/src/App.tsx` has the React application. The core logic of how the frontend will interact with the wallet and the blockchain.
+  Both combined contain the key pieces of code needed to make an Aptos fullstack app using Pyth!
+
+### How to deploy the smart contract :
+
+- Use `aptos init` with rest_url : `https://testnet.aptoslabs.com/` and faucet `https://faucet.testnet.aptoslabs.com` to generate a new keypair.
+- Use a faucet to airdrop testnet APT to your newly created account by calling `aptos account fund-with-faucet --account default`. If this doesn't work, I have had success importing my private key from `.aptos/config.yaml` into Petra and clicking the airdrop button. Otherwise send APT from another account.
+- Get your account address from `.aptos/config.yaml` and replace `mint_nft="0x19f8503273cdb5aa93ffe4539277684615242127aa2e65ef91424136a316c9c7"` by `mint_nft="<ADDRESS>"` in `Move.toml`
+- `aptos move compile`
+- `aptos move publish`
+
+### How to run the webapp :
+
+- In `app/src/App.tsx` replace `const MINT_NFT_MODULE = "0x19f8503273cdb5aa93ffe4539277684615242127aa2e65ef91424136a316c9c7"` by `const MINT_NFT_MODULE = "<ADDRESS>"` the address of your module from above.
+- `npm install`
+- `npm run start`
+- Go to `http://localhost:3000/` in your browser and use Petra wallet to transact with the app.
