Getting started
Deploy Ethereum smart contracts and DApps using tools you already use
The Oasis Network is a high-performance and privacy-first blockchain network. It is operated by a group of independent and decentralized nodes. Each node is free to run its own software and to provide computing services to the public, as long as the network can reach a consensus on the computational results.
Second State has created the Oasis Ethereum runtime that supports both EVM and Ewasm smart contracts and dapps (decentralized applications). A network of Oasis validator nodes will deploy the Second State runtime and provide Ethereum services to the public. With BUIDL, it is a breeze to develop dapps on Oasis Network's Ethereum runtime nodes.
Step1 Configure BUIDL for Oasis Ethereum
The easy way is to just click the link below to launch BUIDL in your browser. It pre-loads all the configurations for you.
Step 2 Get some Oasis ETH tokens for gas
In the Accounts tab, you will see 5 auto-generated addresses, and you can set any of them as default. The default address is used to sign transactions. Because of that, you will need to send a little Oasis ETH into that account to pay for gas fees.
Go to the faucet website, enter your default address from BUIDL and give yourself some gas.
Now, go back to BUILD's Accounts tab and you should see 0.01 OETH (or 10^18 wei) in your default address.
Step 3 Compile and deploy a smart contract
Click on the Compile button to compile the contract. A sidebar will open to show you the compiled ABI and bytecode of the contract.
Next, you can press the Deploy to the chain button on the left panel to instantiate and deploy the contract to Oasis Network Ethereum runtime nodes. You can interact with deployed contracts by calling its public methods from inside BUIDL -- you can set its value and click on the Transact button to save the value onto the blockchain, and then click on the Call button to see the value in the LOG panel.
Step 4 Create an HTML Dapp
Once deployed, click on the dapp button on the left bar to work on your DApp.
The HTML tab above shows a simple HTML page with two buttons.
Next, go to the JS tab. It shows JavaScript on how to interact with the smart contract. It provides event handlers for the buttons. When a user clicks on the button, the JavaScript calls the smart contract functions via the web3 library.
Finally, click on the Run button to run the DApp. You will see the DApp UI in the right panel. You can click on the Set Data button to store a number, and Get Data button to retrieve the stored number.
Congratulations. You now have a complete DApp deployed on the Oasis Network!
Next, you can go through our tutorials to create and publish a decentralized social media app or your own ERC-20 tokens to be traded on Uniswap!
