Etherscan.io api client for R (work in progress)

etherscanr

The package offers an easy way to use the etherscan.io API to query information about the Ethereum network. The package uses Rmpfr for number represenstation where possible.

Currently work in progress. This is an unofficial package. As always use it at your own risk.

Install

Currently, the package is only available from GitHub:

devtools::install_github("dirkschumacher/etherscanr")

API

• Accounts
  • etherscan_transactions get all transaction of an account
  • etherscan_internal_transactions get all internal transactions
  • etherscan_balance retrieve account balances
• Stats
  • etherscan_ethsupply returns the total Ether supply in Wei
  • etherscan_lastprice returns the last price in USD
• Helpers
  • to_ether converts wei to ether using the Multiple Precision Floating-Point Reliable (MPFR) library.

Example

For example let us examine all the transactions of account 0x6F46CF5569AEfA1acC1009290c8E043747172d89:

library(etherscanr)
library(dplyr)
library(ggplot2)
etherscan_transactions("0x6F46CF5569AEfA1acC1009290c8E043747172d89") %>% 
  mutate(value = to_ether(value, from = "wei")) %>% 
  filter(value > 0) %>% 
  ggplot(aes(x = timeStamp, y = value)) + 
  geom_point() +
  stat_smooth() + # we smooth it just because it looks nice ;)
  theme(legend.position = "bottom") + 
  expand_limits(y = 0)
