# **Minting Cycles in Motoko**
This repository provides an example of how to **programmatically mint cycles** in **Motoko** by interacting with the **ICP Ledger** and the **Cycles Minting Canister (CMC)**.
## **Overview**
To mint cycles for a canister, the process involves two main steps:
1. **Send ICP to the CMC canister** via an `icrc1_transfer` transaction on the ICP ledger.
2. **Notify the CMC** with the block index and canister ID to convert the ICP into cycles for the target canister.
### **Process Flow**
```mermaid

User->>Ledger: Send ICP to CMC via Ledger
Ledger-->>User: Return block index
User->>CMC: Send block index and canister ID
CMC->>Canister: Mint cycles
CMC-->>User: Confirm cycles minted
```

```
## **How It Works**
1. Transfers ICP to the **CMC canister**.
2. Retrieves the **block index** from the transfer.
3. Calls `notify_top_up` with the **block index** and **target canister ID**.
4. The **CMC converts ICP into cycles** and credits them to the specified canister.
