FracturedMibera — Soulbound Companion Collections

From MiCodex, the free Mibera encyclopedia.

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

[view source]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.

[view source]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

[view source]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

[view source]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)
