# Guide: How to Upload a Smart Contract on the Juno Chain

{% embed url="<https://youtu.be/e_-xxpfQfwU>" %}

## **Preparation:**

**Required Materials:** A computer with an internet connection, familiarity with GitHub, and basic knowledge of smart contracts.

## **Steps:**

1. **Find an Example Smart Contract:**

(Note: The steps here mainly involve browsing, no specific bash commands.)

In this tutorial we will be using [https://github.com/Reecepbcups/cw-clock-exampl](https://github.com/Reecepbcups/cw-clock-example)

2. **Connect to the Juno Testnet:**

Check out our new video that shows you how to deploy a local env

<https://github.com/Reecepbcups/cw-clock-example>

3. **Create a Juno Wallet:**

```json
bash junod keys add MyWalletName
```

**5. Claim junox Test Tokens:**

Head to Juno Discord <https://discord.com/invite/caEBtA4QDb> and find FAUCET section. In there you can get some using the API provided and inputting the wallet address you created in the previous step. <https://faucet.reece.sh/uni-6/JUNO_ADDRESS_HERE>

**6. Verify Token Receipt:**

```
junod query bank balances [YOUR_WALLET_ADDRESS]
```

**7. Configure the Juno Command Line:**

```json
bash junod config node [NODE_URL] 
junod config chain-id [CHAIN_ID] 
junod config gas auto 
junod config gas-prices 0.025ujuno
```

**8. Deploy the Smart Contract:**

Assuming you've downloaded clock\_example.wasm to your current directory

```
junod tx wasm store clock_example.wasm --from MyWalletName --gas 1500000 --chain-id [CHAIN_ID]
```

**9. Instantiate the Smart Contract:**

Replace \[CODE\_ID] with the code ID obtained from the previous step e.g 3785

```json
 junod tx wasm instantiate [CODE_ID] '{"count": 0}' --label "my-clock-instance" --from MyWalletName --amount 100ujuno
```

**10. Interact with the Smart Contract:**

Query the smart contract (replace \[CONTRACT\_ADDRESS] with the address from instantiation) junod query wasm contract \[CONTRACT\_ADDRESS]

```json

junod tx wasm execute [CONTRACT_ADDRESS] '{"increment": {}}' --from MyWalletName --amount 10ujuno
```

### **Conclusion:**

* You've now successfully uploaded, instantiated, and interacted with a smart contract on the Juno testnet.
* If you have further questions or ideas, join the Juno community on Discord, particularly the "developer lounge".

**Note:** Adjust the bash commands to fit your specific situation, and always double-check them, especially when working with real tokens or live environments.\\
