# Web3

Our official Ethereum contract is located at [0x7553a5ced41c29fa4833ebe65ec9da6e2a9efdf0](https://etherscan.io/address/0x7553a5ced41c29fa4833ebe65ec9da6e2a9efdf0#internaltx).

Our contract was [audited by Cyfrin](https://github.com/Cyfrin/cyfrin-audit-reports/blob/main/reports/2025-04-24-cyfrin-cryptoart-v2.0.pdf).  

#### **Standards**<br>

* **ERC721:** NFT standard (Enumerable, Burnable).
* **ERC2981:** NFT Royalty Standard.
* **IERC7160:** Multi-Metadata for managing pairing status.
* **Story Inscriptions/iStory:** Interface for adding creator/collector stories.

#### **Decentralization**

When an NFT is created (minted), its metadata is permanently stored on the InterPlanetary File System (IPFS). This ensures your NFT remains tradable even if Cryptoart.com shuts down.

How is the redemption status updated?&#x20;

Our contract uses the ERC-7160 standard to toggle a single metadata trait (redeemable = TRUE/FALSE). NFT holders and Cryptoart.com (since it's tied to a service we provide) can update the redemption status.&#x20;
