Fire up local network

First, fire up avash.

Add Custom RPC to Metamask

Next, install Metamask.

Now, add your local network to Metamask. Networks -> Custom RPC -> New Network

• Network Name: Avalanche C-Chain
• New RPC URL: http://localhost:9650/ext/C/rpc
• ChainID: 43110
• Symbol: C-AVA

Import the whale account

Now, import the local network C Chain whale. In metamask "Import Account"

• Private Key

This will give you a balance of 1,000,000,000 C-AVA

Remix

Next, go to Remix. In the Deploy and Run tab set ENVIRONMENT to "Injected Web3". This will prompt you to connect Remix to Metamask. Next, Open Storage.sol in the File Explorers tab. Now, in the Solidity Compiler tab click Compile 1_Storage.sol

Back in the Deploy and Run tab click Deploy. Even if you get the failure popup just click through and approve the tx with metamask. In the same tab under the "Deployed Contracts" heading open the Storage contract and paste 31415927 in to the store input field. Confirm and pay the tx with metamask. Lastly, click the retrieve button to get the value from the blockchain.
