Eth.rb

Eth.rb is an open-source Ruby library for constructing, signing and broadcasting Ethereum transactions. It separates key handling from node management and includes tools for ABI and RLP encoding, RPC connections, signatures, token transfers and smart-contract interactions.

Understand the project

Practical overview

When it fits

Use Eth.rb when a Ruby application needs Ethereum transaction, signature or contract-interaction components, especially when key handling and node connectivity should be managed separately.

Who it is for

  • Ruby developers building Ethereum-enabled applications.
  • Teams integrating transaction signing and submission into Ruby backends.
  • Developers working with Ethereum contract calls, ABI data or signed-message authentication.

Documented uses

  • Construct and sign Ethereum transactions in Ruby.
  • Broadcast signed transactions through a local or remote node.
  • Encode and decode ABI data and interact with smart contracts.
  • Sign messages and recover signatures for authentication workflows.
Before you choose

Requirements & limits

  • The project is a Ruby library distributed as the eth gem, rather than a hosted service.
  • The README describes transaction signing separately from broadcasting, which can be routed through local or remote nodes.
  • The documented RPC client supports IPC, HTTP and WebSocket connections.
  • The feature list includes ABI and RLP encoding, Solidity bindings, message signatures, typed transactions and smart-contract operations.
  • The project specifies the Apache-2.0 license.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install the eth Ruby gem

Add the eth library to a Ruby application or install it as a gem.

Before you start

  • A Ruby environment that can install gems.

Steps

  1. For an application using Bundler, add gem "eth" to its Gemfile.

  2. Alternatively, install the gem with gem install eth.

Expected outcome

The `eth` gem is installed or declared as an application dependency.

Guide limitations

  • These steps cover installation only; they do not configure a node or demonstrate transaction construction, signing, or broadcasting.
