“The best easy-to-use Canister Management Platform in IC ecosystem”
Personal development space
Comprehensive graphical centralized management
Webassemblies are saved uniformly and support reuse WebAssembly
Easy to use UI interface to deploy and manage your CANISTERS
iCAN = “I” C + “Canister”
It is an on-chain Canister management tool built on the ICP blockchain.
iCAN helps developers manage the Canister they create by a graphical interface, to create contracts, download WebAssembly modules, manage Canister indicators, etc.
Dynamic change of Canister’s Settings
More convenient Canister Management
Detailed description of Canister
Support ICP-Cycles exchange, and deposit Cycles to Canister directly
Timely feedback on the status of Canister, so that developers can understand the current status of Canister and manage it in time
