Using ThunderCore with Blockmason Link
ThunderCore is an Ethereum compatible, Smart Contract platform boasting 1,200+ transactions-per-second (TPS), quick block confirmations and low gas costs, making it quick and easy for DApps to deploy and scale.
In this onboarding example, we will deploy a smart contract to the ThunderCore Testnet.
You can obtain some testnet TT tokens from ThunderCore Testnet Faucet to be sent to your Link default account address (note you need to sign-in with Google or Github):
- Note: ThunderCore also offers a small amount of free Mainnet TT tokens to build applications there. See https://developers.thundercore.com/docs/get-tokens/
API project setup in Link
- In Link, either press the
+ Create newbutton above the code editor or open up the setting dropdown menu and select
New Project- both which starts the new project wizard.
- Under Which contract would you like to use?, select
Ownershipif the contract already exists, or select
Create newand then copy and paste the
Ownership.solcode into the Source Code field. Set the Display Name as
- Under Which Ethereum account would you like to use?, use the
Default Account. This is the account we seeded with test TT tokens as part of the setup.
- Under Which network would you like to use?, select
Create newand call it
ThunderCore Testnet. Keep the Block Confirmations Needed at 0.
At the time writing this guide, ThunderCore uses the byzantium EVM Version. Please check https://developers.thundercore.com/docs/migrate-to-thunder/ for the latest version information.
- Under Which connector would you like to use?, select
Create new. Call this connector
ThunderCore Testnet Connectorand use the URL
https://testnet-rpc.thundercore.com(see https://developers.thundercore.com/docs/migrate-to-thunder/ for more details). Ensure the Network selected is
ThunderCore Testnet. Press
- Now we just need to label our Deployment. Under Where is your contract deployed?, select
Create new. Call this deployment
Ownership ThunderCore Testnet Deployment. Since we do not have an existing contract deployment, leave the Address field blank. Ensure the Account is the
Default Account, the Contract is the
Ownershipcontract and the Network
ThunderCore Testnet. Press
- Now we're ready to deploy our contract to the ThunderCore Testnet. Press
Deployand you should get a deployment in progress indicator icon. This might take up to a minute to complete. If deployed correctly, you'll proceed to the next step to set up your API.
- Now we label our Ownership contract API. Under Name, call it
ownership-thundercore-testnetAlso add in a human-readable display name. Ensure you are using the correct Contract Deployment. Press
- Now we label our Ownership API Consumer. This would normally be the name of the app or service calling the API. For example, let's call the consumer
Collectible Stamps App. Ensure you are using the correct API and Account. Press
- Lastly, your consumer needs to authenticate with the Ownership API. An OAuth2.0 Client Secret is automatically generated. Ensure you are using the correct Principal/Consumer. Press
Once you hit
Finish, you should end up back at Home page and see your Ownership code in the IDE, the API tab and a gear icon containing the
client_secret at the bottom of the page which you will use in your app.
Let's also check that our Ownership contract deployed correctly on the ThunderCore Testnet. Click on the
Ethereum Contract Deployments menu item to see a list of contract deployments and their addresses. Copy and paste the address of the
Ownership ThunderCore Testnet Deployment into the ThunderCore Testnet explorer https://scan-testnet.thundercore.com/ to see the details of your contract deployment.
In the above example, the contract address on the ThunderCore network is
And we see our contract deployed on ThunderCore!
Now you can go ahead and use the Link API endpoints which are linked to the Ownership smart contract deployed on ThunderCore Testnet!
Test Ownership API endpoints
npm installfrom your Terminal to install the
ownership-link-sdk-demo.js, update the
Finally run the
ownership-link-sdk-demo.jsscript using Node from the Terminal. You should see an output in Terminal similar to the following:
Check your Ownership contract using the ThunderCore Testnet Explorer to confirm the new transactions representing the
Deploying to ThunderCore Mainnet
If you want to deploy on the ThunderCore Mainnet, just follow the same steps above with the following differences:
- Acquire Mainnet TT tokens to send to your Link default account wallet
- Use the use the appropriate ThunderCore Mainnet RPC endpoint.
