Practical overview
When it fits
Use Wordlines when you want a mobile word-puzzle experience with wallet-connected NFT rewards, or when examining its documented proof and transaction flow.
Who it is for
- Mobile players who enjoy word puzzles and want NFT rewards tied to solving them.
- Developers studying how puzzle proofs and mobile wallet transactions can connect to an NFT minting contract.
Documented uses
- Solve a letter puzzle by covering its letters with valid, linked words.
- Use a connected mobile wallet to submit a transaction for an NFT reward.
- Explore a proof-backed puzzle flow involving a mobile client, a proof server and an Ethereum minting contract.
Requirements & limits
The README says the demo is available through TestFlight by contacting the project author to be added as a tester. The public repository lists an MIT license.
- WalletConnect is used to connect the mobile app to a wallet.
- A central server computes zero-knowledge proofs, so proof generation is not fully decentralized.
- The circuit checks letter coverage, dictionary membership and sequential word links; the puzzle dictionary encodes the rule about letters on different sides.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Play WordLines and submit a puzzle solution for NFT minting
Follow the documented mobile-game flow from wallet connection through submission of the NFT-mint transaction to the wallet.
Before you start
- Access to the WordLines mobile app; the README describes a TestFlight demo and says to contact the project author to be added as a tester.
- A mobile wallet that can connect through WalletConnect.
Steps
Connect a mobile wallet to the app using WalletConnect.
Play the puzzle and have the app process the ZK proof and assemble calldata for a transaction calling the NFT-minting smart contract.
Submit the transaction back to the wallet, which handles signing, broadcasting, and gas pricing.
Expected outcome
The minting transaction is submitted to the connected wallet for handling.
Guide limitations
- The README says access to the TestFlight demo requires contacting the author to be added as a tester.
- The app relies on a central server to compute ZK proofs, so the described architecture is not fully decentralized.
- The source does not document what happens after the transaction is submitted to the wallet.
