How do I verify official Mapstone NFTs and smart contracts?
Every smart contract deployed on Ethereum has a unique contract address. Verifying this address helps confirm that an NFT, Marketplace transaction, or token approval is interacting with the official contract rather than an imitation.
Names, symbols, logos, images, and NFT metadata can be copied by scammers. The contract address is the most reliable way to identify the authentic blockchain asset or application.
Official Mapstone contract addresses
| Contract | Ethereum Mainnet Address | Purpose |
|---|---|---|
| MapstoneCore | 0x364CaA63E832158520F90C267E7f9DBeAC0Ed515 |
The official ERC-721 contract used to mint and record ownership of Mapstone NFTs. |
| Mapstone Marketplace | 0x1937265df8Ffcb1A50e1fE80fb366Bbd4076BE72 |
The official contract used to facilitate supported Mapstone Marketplace transactions. |
| Wrapped Ether (WETH) | 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 |
The canonical Ethereum Mainnet WETH contract used for wrapping, unwrapping, and Mapstone Marketplace offers. This contract was not created or operated by Mapstone. |
Always confirm that your wallet is connected to Ethereum Mainnet when reviewing these addresses.
How to verify a Mapstone NFT
- Open the NFT in your wallet or on a blockchain explorer.
- Locate its Contract Address or Token Contract.
- Confirm that the address exactly matches the official MapstoneCore address:
0x364CaA63E832158520F90C267E7f9DBeAC0Ed515 - Confirm that the NFT is recorded on Ethereum Mainnet.
- Review its token ID, current owner, and transaction history on Etherscan.
An NFT displaying the Mapstone name, logo, artwork, address, or metadata is not necessarily authentic if it was created from a different contract address.
Transferring or listing an authentic Mapstone NFT on a third-party marketplace does not change its original MapstoneCore contract address.
Which contract should appear in my wallet request?
The contract displayed by your wallet depends on the action you are completing:
- Minting: The transaction may interact with the MapstoneCore contract.
- NFT Marketplace approval: The request may interact with MapstoneCore and authorize the official Mapstone Marketplace contract to facilitate a future transfer.
- Marketplace purchase, sale, cancellation, or offer acceptance: The transaction may interact with the Mapstone Marketplace contract.
- Wrapping, unwrapping, or approving WETH: The transaction may interact with the canonical WETH contract. A WETH spending approval for Mapstone offers should identify the official Mapstone Marketplace contract as the approved spender.
Some Mapstone actions involve more than one wallet request. For example, your wallet may first request an approval transaction and then request the Marketplace transaction itself. Review each request separately before confirming it.
How to protect yourself from fake NFTs and websites
- Only connect your wallet through mapstone.io.
- Check the complete website domain before connecting your wallet or approving a transaction.
- Do not trust an NFT based only on its name, image, collection title, or logo.
- Compare the complete contract address, not only its first or last few characters.
- Do not approve NFT or token access for an unfamiliar contract or spender.
- Read every wallet message and transaction request before signing or confirming it.
- Never share your private key, Secret Recovery Phrase, wallet password, or one-time login code.
Mapstone Support will never ask you to send cryptocurrency or NFTs to verify your wallet, recover your account, or resolve a support ticket.
What should I do if I am unsure?
If a contract address, NFT, approval request, website, message, or transaction appears suspicious, reject the wallet request and do not continue.
You can submit a support ticket before taking any action. Include the relevant URL, contract address, token ID, transaction hash, or screenshot, but never include private wallet credentials.
See How do I submit and manage a support ticket? for instructions.
