Avalanche's Primary Network is a subnet that has three chains: P-Chain, X-Chain, and C-Chain. The C-Chain is an instance of the Ethereum Virtual Machine powered by Avalanche’s Snowman consensus protocol. The C-Chain RPC can do anything a typical Ethereum client can by using the Ethereum-standard RPC calls. The immediate benefits of using the C-Chain rather than Ethereum are all of the benefits of using Avalanche. These properties that could considerably improve the performance of DApps and the user experience.
Today, we will deploy and test a smart contract on Avalanche using Remix and MetaMask.
Log in to MetaMask -> Click the Network drop-down -> Select Custom RPC
Network Name: Avalanche Mainnet C-Chain
New RPC URL: https://api.avax.network/ext/bc/C/rpc
Network Name: Avalanche FUJI C-Chain
New RPC URL: https://api.avax-test.network/ext/bc/C/rpc
Network Name: Avalanche Local
New RPC URL: http://localhost:9650/ext/bc/C/rpc
On the main net, you can use the Avalanche Wallet to transfer funds from the X-Chain to your C-Chain address. The process is simple, as explained in this tutorial. Wallet can be used on test and local networks, too.
For funding on the test network, you can also use the Test Network Faucet. Navigate to https://faucet.avax-test.network/ and paste your C-AVAX address. All you need to do is add a "C-" prefix and the faucet will switch from AVAX to C-AVAX.
On a local network, you can easily fund your addresses by deploying your own faucet. Tutorial
Open Remix -> Select Solidity
Load or create the smart contracts that we want to compile and deploy using Remix file explorer.
For this example, we will deploy an ERC20 contract from OpenZeppelin.
Navigate to Deploy Tab -> Open the "ENVIRONMENT" drop-down and select Injected Web3 (make sure MetaMask is loaded)
Once we injected the web3-> Go back to the compiler, and compile the selected contract -> Navigate to Deploy Tab
Now, the smart contract is compiled, MetaMask is injected, and we are ready to deploy our ERC20. Click "Deploy."
Confirm the transaction on the MetaMask pop up.
Our contract is successfully deployed!
Now, we can expand it by selecting it from the "Deployed Contracts" tab and test it out.
The contract ABI and Bytecode are available on the compiler tab.
