Project overview

The City Hall of Love is a virtual sanctuary where couples can come together in a digital union, complete with an NFT marriage certificate, followed by joyous celebrations. This project opens the door to marriage for those who face legal constraints, ensuring that love knows no bounds or barriers.

Metaverse frontend

Celebration in chapel

The scene was constructed in the Decentraland metaverse using the Decentraland SDK, with 3D models supplied by the talented 3D artist.

Smart Contract

Opensea collection

I designed a straightforward Ethereum smart contract for minting certificates. Upon one participant completing the minting process, both participants receive a shared NFT certificate in their respective wallets

Backend

I developed a backend server, with help of decentraland authorization module. The server validates data retrieved from the API by cross-referencing it with Ethereum contract data.

Marriage certificate

Once contract transaction is completed and users have minted their tokens - the server generates certificate image, and from here on users are considered virtually married
