Ethereum Node focused on Developer Experience

  


    

    

  


## Features

- RPC support

- state snapshots (`evm_snapshot`), time manipulation (`evm_increaseTime`), mining control (`evm_mine`)

- print out decoded logs and calldata for all transactions (even reverted ones!)

- display revert reasons

- built-in blockchain explorer

- ignore nonce errors (perfect while working with Metamask 🦊)

- much faster (60%) than Ganache

**Note**: current features represent just a gist of what we want to accomplish

## Installation

```

npm install --save-dev deth

```

## Getting started

```sh

deth [config]

```

Sample config (we support only `.js` configs for now):

```js

const BN = require('bn.js')

module.exports = {

  blockchain: {

    accounts: {

      privateKeys: [

        '0x47be2b1589bb515b76b47c514be96b23cd60ee37e81d63c2ae9c92f7d7667e1a',

      ],

      initialBalance: new BN(10000).pow(new BN(18))

    },

    chainId: 420

  },

  debugger: {

    abiFilesGlob: '../contracts/**/out/*.abi'

  }

}

```

NOTE: `debugger > abiFilesGlob`.

You can find defaults [here](https://github.com/ethereum-ts/deth/blob/master/packages/node/src/config/config.ts)

## Roadmap

- original source code (sol) awareness (source maps, memory layouts etc.)

- More advanced block explorer

- real debugger (via webinterface or directly in the IDE)

## Architecture

Currently it uses forked `ethereumjs-vm` as a virtual machine but we evaluate other designs (like writing our own VM). Our state manager and blockchain is entirely in memory, without usage of merkle patricia trees. Snapshots are implemented simply as deep copy which makes our snapshot mechanism much more reliable than one used in `Ganache`.
