# FracturedMibera — Soulbound Companion Collections

> 10 non-transferable ERC-721 collections tied to main Mibera token IDs.

## Overview

FracturedMibera is a set of 10 soulbound (non-transferable) NFT collections on Berachain. Each collection is an independent ERC-721 contract where token IDs mirror the main Mibera collection — if you own Mibera #42, you can mint FracturedMibera #42 in each of the 10 collections.

Tokens cannot be transferred, approved, or burned after minting. They are permanently bound to the minting wallet.

## Mechanics

### Soulbound Enforcement

The `_update` function is overridden to only allow minting (transfers from `address(0)`). Any transfer between addresses or burning reverts with `SoulboundTokensCannotBeTransferred()`. The `approve` and `setApprovalForAll` functions also revert.

### Minting

```
function mint(uint256[] calldata tokenIds) external payable
```

- Caller must own the corresponding Mibera token ID for each requested mint
- Batch minting supported — pass multiple token IDs in one transaction
- Payment: `mintPrice * tokenIds.length` in native BERA
- Ownership verified via `_mibera.ownerOf(tokenIds[i]) != msg.sender`

### Configuration

- `mintPrice` — configurable by owner
- `__baseURI` — metadata base URI, configurable by owner
- `withdraw()` — owner can withdraw collected mint fees

## Deployment

All 10 collections were deployed from a single script (`DeployFractured.s.sol`) that reads configuration from `fracturedData.json`:
- Collection names and symbols
- Shared mint price
- Reference to main Mibera contract address

## Relationship to Main Collection

- Token IDs are 1:1 with main Mibera collection (token #42 mints FracturedMibera #42)
- Ownership of the main Mibera NFT is required at mint time
- After minting, the Fractured token is independent (selling the main Mibera does not affect the Fractured token, but it cannot be transferred anyway)
