There are several alternative open-source projects in the web3 & swift field. But our library is the most technologically advanced and adopted by community.

We are keep growing. Thank you for your support!

2. Boilertalk/Web3.swift

   • Web3 library for Swift. Sign transactions and interact with Smart Contracts in the Ethereum Network.
   • pod 'Web3', '~> 0.4.1'
