Compressed NFTs (cNFTs)

Compressed NFTs (cNFTs) are a format that allows for the creation of massive collections (up to one billion NFTs) without significant time and $TON costs typically associated with minting. The cNFT format combines two types of storage:

• On-chain: Data is stored directly on the blockchain, making it visible and accessible to all network participants.
• Off-chain: Data is stored on a secure server (e.g., Amazon), which enables faster and more efficient operations with NFTs since they do not require direct blockchain processing.

Minting (registering on the blockchain) of a cNFT occurs upon the first interaction with the digital item. At this moment, the cNFT becomes indistinguishable from a regular NFT, as the digital item is added to the blockchain, making it visible and exchangeable. The cost of registering a cNFT on the blockchain is equivalent to the cost of minting a regular NFT, which is a small symbolic fee.

For technical implementation details on how to create and manage cNFTs, please refer to:

• Compressed NFT Smart Contract:: This repository provides the smart contract required for working with cNFTs on the TON blockchain and includes all necessary documentation to get started.

cNFT Indexing Service

The cNFT Indexing Service allows you to add and index your cNFTs via the Tonconsole interface, making them available through TonAPI without requiring immediate on-chain minting.

• Tonconsole Interface: Enables the addition and indexing of cNFTs, making them searchable and accessible across all applications that use TonAPI, including Tonviewer and Tonkeeper, without needing to mint them on-chain until the first interaction.

For more information on how to index your cNFTs using Tonconsole, please refer to the relevant documentation and console usage guides.
