Endless Possibilities with Smart Hashinals

While this demo uses mint count and Chainlink price oracles, the real power of HCS-7 lies in its ability to create NFTs and metadata that evolve based on all kinds of on-chain data—like DeFi metrics, token prices, or user behavior—without needing off-chain infrastructure. Plug in popular smart contracts like SaucerSwap V2 pools and enable your asset to evolve as liquidity swings up or down.

📈

DeFi-Reactive NFTs

Create NFTs that transform based on token prices and liquidity ranges - visualize HBAR price changes, display fees and returns in real-time. Your NFT becomes a living dashboard.

👤

Holder-Reactive Identity

Create NFTs that adapt to their current holder's on-chain identity - transform based on their KNS profile, token holdings,transaction history, and social graph. Your NFT becomes a living reflection of its owner.

🎮

Composable Game Assets

Design items that level up based on complex game achievements - combining multiple contract states,time-weighted scores, and cross-game interactions to unlock new forms and abilities.

Roadmap

Go live on Testnet

Publish the standard in draft mode, open source the tooling to read and create HCS-7 Topics, and publish a number of examples.

Integrate Chainlink Price Oracles Contracts

Add examples utilizing the Chainlink Price oracles to create price-reactive NFTs with HCS-7

Integrate LaunchPage Contracts

Enable the LaunchPage smart contracts to work with HCS-7 examples to create content that changes every time a new mint is made.

Ecosystem Compatability

Ensure HCS-7 works smoothly across the entire Hedera ecosystem

Launch on Production

After obtaining review from peers in the ecosystem and hardening up the infrastructure, publish and enable it on mainnet.

FAQ

How does it work?

HCS-7 combines on-chain data from Smart Contracts, passes them into a WASM Module, and returns the correct Topic Id. WASM Modules can be customized and built for specific needs.

When will Smart Hashinals be live on mainnet?

The standard is currently in a draft standard and undergoing feedback. Upon review and improvements to infrastructure, HCS-7 will go live on mainnet.

How much will Smart Hashinals cost to Inscribe?

Fundamentally the same as regular Hashinals.

Do I need to write code to create Smart Hashinals?

Nope! Pre-created WASM modules and EVM configurations like Chainlink routers will enable utilization immediately. However, newer use cases with different combinations of smart contracts and WASM modules would need custom development.
