“The best easy-to-use Canister Management Platform in IC ecosystem”

Introduction

Easy to use UI interface to deploy and manage your CANISTERS

  1. iCAN = “I” C + “Canister”

    It is an on-chain Canister management tool built on the ICP blockchain.

  2. iCAN helps developers manage the Canister they create by a graphical interface, to create contracts, download WebAssembly modules, manage Canister indicators, etc.

Functions

1.Detailed Management

2.Status Detection

3.Graphical Canister management Interface

4.Created Canister Import

5.WebAssembly Management

Introduce the public interface of iCAN Canister and Hub Canister
