Gold Farmers gamefied on-chain NFT on Blast

Mission

To create a fun gamified NFT, that would stretch our abilities of on-chain technologies. We learned about the Blast L2 blockchain and thought it had interesting mechanics like native yield and gas revenue sharing. That combined with the low prices of on-chain transactions of the Layer 2 blockchains, made a good space to explore this new project.

Result

Gold Farmers collection, an experimental fully on-chain game on Blast. Players could mint fully-refundable Farmer NFT (with lock up period). Each farmer was able to mint a Flower NFT on-chain per season. Each season those flowers could be watered on-chain and had a random chance to grow which gave players more points, as the flower leveled up.

Highlights

Farmers NFT

• Farmer NFT art had over 70 traits all generated as SVGs with scripts, generated and stored on-chain.

Flowers NFT

• Flower NFTs were the main part of the game, where having a farmer allowed you to water flowers, and while staying on-chain see them evolve.

Watering Flower NFTs experience

• Players could use our web-app to interact with the smart contract, see their flowers and water then, generating a random result on-chain.

Farmers list

• A tab to display all your farmer NFTs, with metadata info and links to relevant marketplaces.

Flowers list

• A tab to display all your Flowers, with filtering options, metadata info and links to relevant marketplaces.

Flower details page

• Each flower had a details page, where players could water or use the fertilizer as well as see more detailed info on that flower.

Leaderboard

• The leaderboard is its own on-chain smart contract which kept track of the points of players based on flowers levels and farmers.

Mint Seeds

• Each farmer at the start of seasons could mint a seed for that farmer, we made a page to let players easily mint them.

Over 65,000 on-chain transactions generated

• When players minted flowers, watered or fertilized them for points they made an on-chain transaction.

Tech Stack

• Smart Contract: We used Solidity to create the collections 3 smart contracts in the Blast L2 blockchain.
• On-chain: Everything from the art, metadata to the leaderboard points tracking were kept on-chain.
• On-chain randomization: We used Pyth Entropy for securely generating random numbers on-chain.
• Web App: NextJs, React, HTML, CSS, Typescript were the main technologies used for creating the web-app which interacted with the smart contracts.
• Scripts: We used Python scripts for many utility aspects including distribution of prizes.
