[![Travis-CI Build Status](https://travis-ci.org/datawookie/ether.svg?branch=master)](https://travis-ci.org/datawookie/ether)

The `ether` package provides functions for interacting with the Ethereum network.

The details of the RPC interface along with `curl` examples of interacting with it are documented in the [JSON RPC page](https://github.com/ethereum/wiki/wiki/JSON-RPC) on the Ethereum Wiki.

## Installation

Install from GitHub using

```{r gh-installation, eval = FALSE}

# install.packages("devtools")

devtools::install_github("datawookie/ether")

```

Alternatively there is a stable version listed on CRAN.

## Example

Load the package.

```{r}

library(ether)

```

You'll need to connect to an Ethereum node exposing a RPC interface. By default the package will attempt to connect to a node on `localhost` using port 8545. However, you can also make use of the public RPC nodes hosted by [infura.io](https://infura.io/). Assuming that you have created an infura.io API key and stored it in the `INFURA_MAINNET_KEY` environment variable.

```{r}

set_rpc_address("https://mainnet.infura.io/", key = Sys.getenv("INFURA_MAINNET_KEY"))

```

Once you've configured the connection to RPC you are ready to interact with the Ethereum blockchain.

```{r}

eth_blockNumber()

```

```{r}

eth_gasPrice()

```

```{r}

eth_getBalance("0xD34DA389374CAAD1A048FBDC4569AAE33fD5a375")

```

```{r}

eth_getTransactionCount("0xD34DA389374CAAD1A048FBDC4569AAE33fD5a375")

```
