Incognfto: A Private NFT Gallery

The NFT Privacy Solution That Puts Owners in Control

In the fast-evolving NFT landscape, data security, intellectual property protection, and privacy concerns are crucial. We built Incognfto to address these challenges by offering a solution that allows NFT owners to mint and enjoy their assets securely. Leveraging Spheron Network and Lit Protocol, Incognfto ensures exclusive access to NFTs for rightful owners while maintaining ownership control and privacy.

Our vision is to prioritize security, privatization, and an enriched NFT experience for owners, artists, collectors, and enthusiasts. By harnessing the Lit Protocol's advanced encryption and programmable signing, Incognfto empowers users to manage sovereign identities and maintain client-side data encryption without relying on centralized key custodians. This innovative approach sets a new standard for NFT ownership, enhancing security and privacy in the dynamic world of NFTs.

What is Lit Protocol?

Lit Protocol is a distributed key management network that offers encryption and programmable signing services based on threshold cryptography. It enables various use cases, including DeFi, infrastructure, sovereign data, Web3 social, gaming, and token gating for Web2 apps, providing developers with a versatile toolkit for enhancing security, privacy, and access control in the blockchain and decentralized space.

To illustrate how Incognfto stands out as a superior option compared to other NFT galleries, we have prepared a helpful comparison chart for your better understanding.

How does it work?

Incognfto follows a straightforward workflow to ensure privacy and secure access to NFTs. Here's a high-level overview:

1. Encryption: Safeguarding NFT Content

At the core of Incognfto's privacy measures is a robust encryption process that employs the Lit Protocol to ensure confidentiality and protection of NFT content from unauthorized access. The encryptFile function plays a vital role in this process, utilizing the encryptUpload function from the Spheron Browser SDK to encrypt NFT files before uploading them to IPFS. The process involves the following steps:

  • First, the function checks if the Lit Node client is connected; if not, it establishes the connection.

  • Second, it obtains an authentication signature (authSig) through LitJsSdk's checkAndSignAuthMessage method, ensuring user authentication and access validation during encryption.

  • Third, the createAccessControlCondition function defines access control conditions, determining authorized users for decryption and data access.

  • Fourth, the encryptUpload function has parameters like authSig, access control conditions, blockchain network, NFT file, Lit Node client instance, and additional configuration.

  • Finally, the encryptFile function returns the encryption result, which may include the encrypted file's location or identifier.

async encryptFile(id: string, file: any, configuration: any) {
   if (!this.litNodeClient) await this.connect();
   const authSig = await LitJsSdk.checkAndSignAuthMessage({ chain });
   const uploadRes = encryptUpload({
     accessControlConditions: createAccessControlCondition(id),
     litNodeClient: this.litNodeClient,
   return uploadRes;

2. Minting and Ownership: Creating Unique NFT Tokens

Once an NFT is encrypted on Incognfto, the platform mints it on the blockchain, creating a unique ownership token linked to the owner's wallet address. This token grants exclusive decryption and viewing privileges to the NFT's content, ensuring controlled access. To achieve this, Incognfto harnesses the robust access controls offered by the Lit Protocol. The createAccessControlCondition function takes an id parameter, representing the NFT's unique identifier, and constructs an access control condition using the Lit Protocol's schema. By implementing and leveraging access control conditions as shown in the provided code snippet, Incognfto ensures that only the rightful NFT owner can access and decrypt the locked data, enhancing security and privacy within the gallery while empowering NFT owners with full control over their digital assets.

const client = new LitJsSdk.LitNodeClient({});
const chain = "mumbai";

const createAccessControlCondition = (id: string) => {
 return [
     contractAddress: process.env.REACT_APP_CONTRACT_ADDRESS,
     standardContractType: "ERC721",
     method: "ownerOf",
     parameters: [id],
     returnValueTest: {
       comparator: "=",
       value: ":userAddress",

3. Unlocking NFTs

Unlocking an NFT is a seamless experience for authorized users on Incognfto, as the platform verifies their access rights before decryption. The Lit Protocol's access control conditions are pivotal in determining who can access and decrypt the locked NFT data. The decryption process is handled by the decryptFile function, which ensures a secure connection with the Lit Node client and authenticates users with an authentication signature (authSig) from LIT Protocol's checkAndSignAuthMessage method. Using the authSig and IPFS CID, the decryptUpload function decrypts the NFT file, presenting the unlocked content to authorized users through the decryptFile function. This enables users to fully enjoy their NFTs within the private gallery, with complete ownership and control.

async decryptFile(ipfsCid: string) {
   if (!this.litNodeClient) await this.connect();
   const authSig = await LitJsSdk.checkAndSignAuthMessage({ chain });
   const decryptedFile = await decryptUpload({
     litNodeClient: this.litNodeClient,
   return decryptedFile;
