- Interaction with remote node via JSON RPC 💭
- Smart-contract ABI parsing 📖
- ABI deconding (V2 is supported with return of structures from public functions. Part of 0.4.22 Solidity compiler)
- RLP encoding
- Interactions (read/write to Smart contracts) 🔄
- Local keystore management (
gethcompatible) - Batched requests in concurrent mode
- Literally following the standards:
- Comprehensive Unit and Integration Test Coverage
- Complete Documentation
- Not every JSON RPC function is exposed yet, and priority is given to the ones required for mobile devices
- Functionality was focused on serializing and signing transactions locally on the device to send raw transactions to Ethereum network
- Requirements for password input on every transaction are indeed a design decision. Interface designers can save user passwords with the user's consent
- Public function for private key export is exposed for user convenience but marked as UNSAFE_ :) Normal workflow takes care of EIP155 compatibility and proper clearing of private key data from memory
- iOS 9.0+ / macOS 10.11+
- Xcode 9.0+
- Swift 4.1+

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:
$ sudo gem install cocoapodsTo integrate web3swift into your Xcode project using CocoaPods, specify it in your Podfile:
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '9.0'
target '<Your Target Name>' do
use_frameworks!
pod 'web3swift'
endThen, run the following command:
$ pod installCarthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.
You can install Carthage with Homebrew using the following command:
$ brew update
$ brew install carthageTo integrate web3swift into your Xcode project using Carthage, specify it in your Cartfile:
github "web3swift/web3swift" ~> 1.1.9
Run carthage update to build the framework and drag the built web3swift.framework into your Xcode project.
You can try lib by running the example project:
- Clone the repo:
git clone https://github.com/matterinc/web3swift.git - Move to the repo:
cd web3swift/Example/web3swiftExample - Install Dependencies:
pod install - Open:
open ./web3swiftExample.xcworkspace
