Today we completed MyZubster’s first full NFT end-to-end flow.
MyZubsterCharacter is now deployed on Ethereum Sepolia, and the first real Character NFT mint has been completed successfully.
What is working now:
ERC-721 MyZubsterCharacter smart contract
Deployment and interaction on Ethereum Sepolia
Wallet ownership verification using challenge + cryptographic signature
On-chain Character NFT minting
Automatic transaction receipt verification
Contract address, token ID, and wallet owner validation
NFT registration in the MyZubster backend
Asset status changes to minted only after successful on-chain verification
Genesis test
Token ID: #1
Network: Ethereum Sepolia
Status: minted
On-chain verification: true
Contract
0x5Ce389EB9222d40917b6110079a7D93CBf25B4D0

This means the Character NFT MVP is no longer just code or a simulation. The full flow — account → wallet → signature → mint → blockchain → verification → backend — has now been executed successfully end to end.
Next steps: UI integration, metadata and asset pipeline, marketplace functionality, and further contract/security hardening.
Build in public. Ship. Verify. Iterate.
