FAQs

Technical FAQ

Is ThunderCore compatible with Ethereum?

ThunderCore and Ethereum use the same virtual machine (EVM). As such, smart contracts that run on Ethereum can run on ThunderCore as well, which means that ThunderCore supports coding languages that Ethereum supports; including Solidity, Vyper, etc.
Furthermore, ThunderCore exposes Ethereum's JSON RPC, which makes it compatible with tools that use the JSON RPC, such as web3.js, MetaMask, Truffle, etc.
In general, any DApp that runs on Ethereum can be made to run on ThunderCore with very few or minor modifications. Visit the tutorial to learn how to migrate from Ethereum to ThunderCore.

Is ThunderCore decentralized?

Yes, ThunderCore is based on decentralized trust. Users have to trust neither the consensus nodes, nor the accelerator. Users only need to trust the honest majority for ThunderCore to be secure (which is the same for standard blockchains). To understand the consensus algorithm, see the Whitepaper.

How do I write smart contracts for ThunderCore?

Since ThunderCore is compatible with Ethereum smart contracts, you can write smart contracts the same way you would for Ethereum. Most people use Truffle, but other tools should work as well. Check out our tutorial to deploy your own game.

How do I deploy smart contracts on ThunderCore?

The process for deploying smart contracts on ThunderCoure would be the same way that you deploy them on Ethereum. Most people use Truffle, but other tools should work as well. See our tutorials on building and migrating Ethereum DApps to ThunderCore.

What if I already developed a DApp or smart contracts on Ethereum?

Since ThunderCore is compatible with Ethereum, it’s easy to migrate DApps and smart contracts to ThunderCore in just a few steps. Check out our migrate Ethereum DApps to ThunderCore tutorial.

How much does it cost to use ThunderCore?

On the ThunderCore Mainnet, ThunderCore (TT) are used to pay for gas fees. ThunderCore doesn't rely on an expensive Proof-of-Work (PoW) algorithm and is therefore able to produce blocks at a lower cost.

Can I mine or stake ThunderCore (TT)?

Since ThunderCore utilizes Proof-of-Stake, as a result all ThunderCore (TT) are premined. No new tokens can be mined as we do not mint new tokens as part of our consensus process. ThunderCore validators, called committee node members, earn rewards through gas/txn fees. People can take part in the ThunderCore consensus mechanism and participate in securing the ThunderCore blockchain upon its public launch.

How can I get access to ThunderCore?

ThunderCore is a public chain. The ThunderCore Mainnet is easily accessible via the published network addresses found here.

Is ThunderCore available for DApp development?

Yes. We encourage DApp developers to experience a boost in performance while leveraging full EVM compatibility. DApps can be migrated to ThunderCore within as fast as five minutes.
ThunderCore (TT) are available to individuals and teams desiring to try the ThunderCore Mainnet. The ThunderCore Testnet has been running and available since February 2019 for DApp development. You can get started by obtaining Testnet Tokens from here. Please also stay on the lookout for incentives to port your DApps to ThunderCore!
Right now you will have to configure most of the wallets to point to any one of the custom RPC url of ThunderCore:

Is ThunderCore(TT) an ERC-20 token?

No, ThunderCore (TT) is the native currency of an independent public blockchain, ThunderCore.
ThunderCore is an Ethereum Virtual Machine (EVM) compliant blockchain. Tokens based on the ERC-20 standard can be minted and deployed on ThunderCore.

What can I do with ThunderCore (TT)?

ThunderCore (TT) is the native currency of an independent public blockchain, ThunderCore. ThunderCore (TT) can be used to build and monetize decentralized applications on the ThunderCore blockchain. ThunderCore (TT) can be used to pay for gas costs, execute transactions and underwrite smart contracts on the ThunderCore blockchain.

Why is MetaMask showing my tokens as ETH and a large USD amount as its value?

When adding a custom RPC URL in MetaMask, MetaMask by default treats any token/coin as ETH and shows the portfolio value using the USD price of ETH.
To correct this, use the "Show Advanced Options" menu when adding the custom URL for Thunder Core (https://mainnet-rpc.thundercore.com). Add 108 (0x6c) as Chain ID and TT as the Symbol.
Once you do that your Thunder Tokens will appear as TT on you MetaMask wallet.

Gas Fees

Gas Price

Gas Limit

  • Use the eth_estimateGas RPC call to estimate the computation and storage cost required by the transaction. If you know for sure the destination address is a regular account and not a smart contract, you can use specify a gas limit of 21 K (21,000)

How to Prevent Rate Limit?

  • Optimize application program logic and reduce the frequency of query
  • Use batch query

The ability to query ancient states

  • Balancing network performance by trading off the ability to query ancient states, such as account balances from months ago. Querying RPC with block numbers may fail if the timestamp of that block was processed a long time ago. Including:
    • eth_getBalance
    • eth_getCode
    • eth_getTransactionCount
    • eth_getStorage
    • eth_call

Address Generation

  • ThunderCore addresses use the same format as Ethereum e.g. 0x519A3B21130Eb8496F7a8E4782fa3106aE4cFF27
  • HD Wallet derivation path to obtain private keys from a 12-word mnemonic is (BIP32 Derivation Path): m/44'/1001'/0'/0
