Migrate from Ethereum

Overview

Because ThunderCore is a fork of geth, our blockchain natively supports EVM-compatible smart contracts. This document describes the steps required to port your existing Ethereum DApp to ThunderCore. If you haven't created a DApp before, checkout deploy your own game tutorial.

Connecting to our network

To connect to our network, see the RPC endpoints below. You can perform any RPC operation available in Ethereum on these URLs.

Network	RPC endpoint	Network ID
Mainnet	https://mainnet-rpc.thundercore.com	108
Testnet	https://testnet-rpc.thundercore.com	18

If you're using MetaMask, specify one of these URLs as a new, custom RPC.

If you're using Truffle, add the following section to your truffle.js file:

module.exports = {
  networks: {
    development: {
      host: 'localhost',
      port: 8545,
      network_id: '*' // Match any network id
    },
    thunder-mainnet: {
      provider: function() {
        return new HDWalletProvider(mnemonic, "https://mainnet-rpc.thundercore.com");
      },
      network_id: '108',
    },
    thunder-testnet: {
      provider: function() {
        return new HDWalletProvider(mnemonic, "https://testnet-rpc.thundercore.com");
      },
      network_id: '18',
    }
  },
  compilers: {
      solc: {
        version: "0.5.9",
        settings: {
          // see the solidity docs for advice about optimization and evmversion
          optimizer: {
            enabled: true,
            runs: 200
          },
          evmVersion: "byzantium" // Current EVM on ThunderCore is fixed to "byzantium"
        }
      }
    }
}

Solidity compiler

We're currently in the process of integrating the latest EVM changes (St. Petersberg) into our codebase, but until we'll have to lock the evmVersion of solc to byzantium. The relevant truffle config is shown above.

Yup, that's it

No need to rewrite your smart contracts or change any of your infrastructure code, you should be good to go! If you are facing any problems, post it in our Discord for direct access to, and immediate help from, some of our developers.
