KARASTAR — Play-to-Earn Ecosystem

Discipline

Blockchain / GameFi

Full GameFi ecosystem: NFT characters, dual-token economy, staking, and PvP on BNB Chain.

The brief

What it is and how it was built.

KARASTAR is one of the most complete GameFi products Golden Sea has shipped. The client, a crypto gaming studio, had a strong concept but no engineers, and needed one team to build both the game and the blockchain side.

Golden Sea designed two tokens. KAR is earned by playing and spent on items, breeding and entry fees. KSHARE is for governance and staking and goes to long-term holders, so players have a reason to hold rather than sell everything they earn straight away.

The contracts were written in Solidity and deployed on BNB Chain for its low fees. Before mainnet, CertiK ran a full security audit, and every issue it found was fixed before launch.

The Unity client connects to the blockchain through an SDK the team built on Web3.js, with MetaMask or WalletConnect. Inside the game it feels like an ordinary mobile RPG; players only deal with on-chain assets when they open the wallet tab. In its first 30 days the project passed 15,000 registered wallets.
