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

An Execution Abstraction framework that allows apps and frontends to fulfill their users' intents and retain their users' MEV by running auctions that match User Operations with Solver Operations. Users do not need a smart wallet. Permissionless for users, apps, and Solvers. Backwards-compatible with existing apps.

Tiny library with utility functions that can help with signing and verifying EIP-712 based messages

Tools to work with the Injective Chain, Injective EVM and EIP712.

311 byte EIP712 Signing Compliant Delegate-Call Enabled MultiSignature Wallet for the Ethereum Virtual Machine

TypeScript library that supports validation of any type of signature: account abstraction (ERC-1271, ERC-6492), standard signatures, ERC-712

Ethers.js Signer that connects to GCP KMS

EIP712 data structure management for python

A javascript library for working with typed structured data as defined by EIP712

Wizard-SDK, a TypeScript software development kit, is designed to visualize diverse protocol EIP-712 messages and simulate transactions that users sign daily in the web3.0 environment.

This repository shows how to implement signTypedData_4(EIP712) with NodeJS

PiggyFi is a Defi savings platform, without the need of an ethereum client e.g TrustWallet. That allows people from countries suffering from high inflation rates to save in a stable currency such as the USD, by leveraging on Stable cryptocurrencies such as USDT and generating interest on their savings through yield farming.

A limit order match engine and backend service with simple account management using RESTful API in Rust-lang.

Signature verification implementation for EIP712

Generalized signature validator supporting various signing standards.

A reference implementation of an EIP-5539-compatible revocation registry for Ethereum.

An example implementation of EIP712 using hardhat.

The node module that allows you to control your Ethereum revocation lists & resolve revocation keys.

🗝️ EIP-712 is a standard for structuring typed data for Ethereum smart contracts. It is a standard for how to encode typed data according to EIP-191 so that the encoded data may be used to produce a cryptographic hash and a signature.

How to verify Ethereum `personal_sign` EIP-191 and `eth_signTypedData_v4` EIP-712 in NEAR Protocol with Rust?
