Hey, I'm Bora 👋

I build the on-chain layer for games and digital assets — smart contracts, NFT and token infrastructure, cross-chain bridging, and the engine-side integration that makes all of it work inside a real game. In games since 2020, in blockchain since 2021, and founder of Game Block LLC since January 2025. The systems I have shipped carry $4M+ in NFT volume and have moved live collections between chains.

Before Game Block I spent a year and a half as Blockchain Integration Engineer on Providence, one of the few fully on-chain AA+ titles on the market. I work both sides of the wall — engine and chain — which is exactly where most projects lose their months.

🤝 What I'm Looking For

I am not job hunting — I am looking for people to build with. Game Block is taking on new partners, and I have projects of my own that deserve better than being built alone.

🎮 Game studios that need the on-chain half done properly — integration, economy, contracts
🪙 NFT and token teams who want infrastructure that survives launch day, not just a demo
💰 Investors and publishers for the Medieval War game and the products in the workshop below
🌐 Chains and ecosystems looking for a team that actually ships games on them
🧠 Co-founders and collaborators — if one of the workshop projects is the thing you have been wanting to build, say so

📬 info@gameblock.us — tell me what you are building.

🧱 Game Block

Game Block is a small engineering studio shipping on-chain infrastructure for games and tokens — plus the game-side integration that makes any of it usable.


🔗 In-game blockchain integration	Wallet, signing and transaction flow inside your Unreal Engine, Unity Engine or web client, and the contracts behind it
📊 Game economy design	Sinks, mints, supply caps and reward curves modelled before deployment, then written into the contracts
⚙️ Game logic on-chain	Governance, clans, betting, rentals — rules as a protocol other developers can build on
🖼️ NFT collections & token launches	Asset pipeline, metadata, mint mechanics, staking and vesting, gas-checked end to end

We put the chain behind the game loop instead of in front of it: signature-gated actions, batched writes, and a client that stays playable when the network is slow.

Blockchain should be infrastructure — not hype. Systems that scale under load, survive production, minimise trust assumptions, and can still be maintained a year later.

⭐ Selected Works

	Ulak — Cross-chain Messaging Infrastructure. Ulak carries verifiable messages between chains. A relay mesh moves the messages, light clients verify them at the destination, and an attestation queue orders them into channels — infrastructure other contracts can build cross-chain features on top of, without trusting a single relayer.
	Quills Adventure — OG NFT project on the Somnia Network. Frontend, backend, event-based custom contracts, a bespoke NFT builder, an on-chain chat app, and the bridge that made Quills the first collection to migrate to Somnia. Two collections, $4M+ in combined secondary volume.
	Quills: The Medieval War — medieval combat game in Unreal Engine 5, built with a designer. Playable demo in the first three months, shown at Tokyo Game Show 2025 and Token2049 Singapore. Announcement teaser →
	Zk Chickens — casual online shooter on zkSync Era, shipped to Google Play. ERC-1155 items minted on the web and usable in the next match. Rewards come out of match fees rather than fresh emissions — skill earns, and the economy does not need new buyers to keep paying.
