Who controls Mapstone’s smart contracts, and what can be changed?
Mapstone uses two primary smart contracts on Ethereum Mainnet. Their addresses are public and can be reviewed on Etherscan.
Official Mapstone smart contracts
| Ethereum Mainnet Address | Purpose |
|---|---|
MapstoneCore0x364CaA63E832158520F90C267E7f9DBeAC0Ed515 |
The official ERC-721 contract used to mint Mapstone NFTs, record their ownership, and store their metadata links. |
Mapstone Marketplace0x1937265df8Ffcb1A50e1fE80fb366Bbd4076BE72 |
The official contract used to process supported listings, offers, and sales on the Mapstone Marketplace. |
Who controls the MapstoneCore contract?
Administrative functions in the MapstoneCore smart contract are controlled by Mapstone’s multisignature Contract Owner Safe wallet. This provides shared control rather than placing administrative authority in a single personal wallet.
These administrative functions include:
- Updating base mint prices
- Updating royalty and platform allocation percentages (such as the referral commission percentage, Neighborhood owner percentage, charity donation percentage, Address Quest™ prize pool allocation percentage, and the Mapstone Marketplace platform fee)
- Updating the official holding wallets that receive specific allocations, such as the Address Quest™ prize pool wallet (
addressquest.mapstone.eth) and charity wallet (charity.mapstone.eth) - Updating an NFT’s metadata
- Permanently burning an NFT
How does Mapstone authorize new NFT mints?
Each valid mint must be approved through Mapstone’s system before it can be submitted to the smart contract. The approval is tied to the wallet completing the mint and the exact NFT information being minted.
This prevents someone from bypassing Mapstone’s review and pricing controls to mint arbitrary NFTs directly through Etherscan. The authorization process does not give Mapstone control over existing NFTs and cannot be used to transfer or reassign them.
Can Mapstone update an NFT’s metadata?
Yes. Only the Contract Owner Safe can update an NFT’s metadata link. This may be appropriate when verified information about a location changes, such as a well known stadium, hotel, landmark, or other point of interest receiving a new official name.
Updating metadata does not change the NFT’s token ID, geographic location, or owner.
If you own a Mapstone NFT and believe its name, image, address information, or other metadata is incorrect or outdated, please submit a request through Mapstone Support. Include the NFT’s token ID or Mapstone page URL and reliable information supporting the requested correction.
Mapstone will review each request for accuracy before deciding whether an update is appropriate.
Can Mapstone permanently burn an NFT?
Yes. Only the Contract Owner Safe can permanently burn an existing NFT. This requires approval through the multisignature Safe wallet.
Burning permanently destroys that token. It does not transfer or reassign the NFT to Mapstone or another wallet.
Can Mapstone transfer or reassign someone’s NFT?
No. Mapstone does not have an administrative function that can forcibly transfer or reassign an NFT to another wallet. Transfers require authorization from the NFT owner.
The Mapstone Marketplace contract can facilitate a sale or transfer only when the NFT owner has authorized the Marketplace transaction. It does not give Mapstone general control over NFTs held in users’ wallets.
Can the smart contract code be changed?
No. The deployed MapstoneCore and Mapstone Marketplace contracts are not upgradeable. Their underlying code cannot be changed or replaced at their existing contract addresses.
The Contract Owner Safe can use the administrative functions already built into MapstoneCore, such as updating prices or metadata, but it cannot add new functions or rewrite the deployed contract code.
How can I verify this information?
You can review both contracts and their public transaction histories using the Etherscan links above. For more information, see How do I verify official Mapstone NFTs and smart contracts?
