a straightforward library to build, sign, and broadcast ethereum transactions anywhere you can run ruby.

ethereum on rails (template): connect metamask to ruby on rails.

This project implements an Ethereum-based token airdrop using Merkle Trees and EIP-712 signatures for secure and gas-efficient claims. The contract ensures that only eligible users (based on a pre-generated Merkle Root) can claim tokens, and it verifies their identity using cryptographic signatures.

A collection of links and resources I collected in order to implement EIP-191 and EIP-712 into geth.

A secure and efficient AWS KMS-based signer implementation for Ethereum and Tron networks. Uses AWS Key Management Service (KMS) for secure key management instead of plaintext private keys, supporting both EVM and Tron transaction signing.
