Etherscan Lite

etherscan-lite - light-weight machinery / helper for the Etherscan (blockchain) JSON HTTP API / web services (note: API key sign-up required)

Usage

Step 0 - Setup - Configure ETHERSCAN API Key

The etherscan lite machinery will (auto-magically) lookup the ETHERSCAN_KEY environment variable or will load a dotenv file (.env) in the working / current directory or use in your script:

Etherscan.config.key = 'YOUR_API_KEY_HERE'

# or

Etherscan.configure do |config|
  config.key = 'YOUR_API_KEY_HERE'
end

Etherscan API Recipes

Let's try the "official" recipes from the Eherscan API docu

  • Get All USDT Transfers from Binance
  • Get the Latest Moonbird Non-Fungible Token (NFT) Transfers
  • List ETH deposits to Arbitrum Bridge

Get All USDT Transfers from Binance

see https://docs.etherscan.io/recipes/get-all-usdt-transfers-from-binance

require 'etherscan-lite'

USDT_ADDRESS       = '0xdac17f958d2ee523a2206206994597c13d831ec7'
BINANCE_HOT_WALLET = '0xdfd5293d8e347dfe59e90efd55b2956a1343963d'

data = Etherscan.tokentx( address: BINANCE_HOT_WALLET,
                          contractaddress: USDT_ADDRESS )
pp data

resulting in:
