Javascript SDK

  • eosjs: A Javascript library which provides an API for integrating with EOSIO-based blockchains using the EOSIO Nodeos RPC API
  • eosjs-keygen: A Javascript library for managing keys in local storage

Swift SDK

  • eosio-swift: A set of components for integrating with EOSIO-based blockchains using the EOSIO RPC API
  • eosio-swift-vault: Consists of two main components--Vault and Vault Signature Provider. Vault is a utility library for working with public/private keys and signing with Apple's Keychain and Secure Enclave. Vault Signature Provider is a pluggable signature provider for EOSIO SDK for Swift. It allows for signing transactions using keys stored in Keychain or the device's Secure Enclave
  • eosio-swift-ios-example-app: A simple application demonstrating how to integrate an iOS app with EOSIO-based blockchains using EOSIO SDK for Swift
