iOS: Mainnet library is not available for iOS. No idea what to use here.
We're using OpenAPI generators, which allows you to build clients for dozens of programming languages, or you can use the REST API directly.
All these clients (PHP, Go, Python, etc...) can't sign transactions or generate private keys, they are thin REST wrappers and defer all important tasks to the REST server.
Here's how this works:
The docs for specific REST methods are here (opens new window).
We are automatically generating some clients, namely:
- PHP (opens new window)
composer require mainnet-cash/mainnet-php-generated
- Python (opens new window)
pip install mainnet
- Go (opens new window)
go get https://github.com/mainnet-cash/mainnet-go-generated
- NodeJS (opens new window) (not auto-generated)
yarn add mainnet-js
...and we'll be adding to this list soon.
To build the client for another language, run the following commands:
git clone https://github.com/mainnet-cash/mainnet-js.git yarn api:build:client $lang
$lang is the language you want to build, see here (opens new window) for the list
