On-chain infrastructure built for you

We build the contracts,
tooling and infrastructure
crypto businesses run on.

Game Block is a small engineering studio. We ship smart contracts, token and NFT launches, staking and vesting systems, and the game-side integration that makes them usable — ten shipped projects across Base, Somnia and EVM chains.

Services

Scoped as fixed deliverables. Each one ends with deployed, verified contracts and the frontend or SDK your team needs to use them.

Cross-chain & bridging

Move tokens, NFTs and messages between chains — the contracts on both ends, plus the interface holders actually use.

Cross-chainBridging

Token launch

Utility or governance token, from contract and access control through distribution and the launch itself.

ERC-20Launch

NFT collection development

Asset pipeline, metadata, mint mechanics and the mint frontend. ERC-721 and ERC-1155, gas-checked.

ERC-721ERC-1155

Staking & vesting

Staking pools and cliff/linear vesting for teams and investors, with an admin surface and a claim UI.

StakingVesting

In-game blockchain integration

Wallet, signing and transaction flow inside your game client, plus the contracts behind it. Unity and web builds.

UnityEVM

Game logic on-chain

Move the rules your game depends on into contracts, so other developers can build on top of them as a protocol.

How we work

Four phases, each with a written deliverable you can review before the next one starts.

Phase 01

Scope

A call, then a written scope: what ships, what doesn't, what it costs.

Deliverable — scope document

Phase 02

Architecture

Contract boundaries, storage layout, upgrade and admin story, threat notes.

Deliverable — architecture note

Phase 03

Build & review

Contracts with tests, internal review, gas pass, external audit if the scope needs it.

Deliverable — tested code + gas report

Phase 04

Launch & handover

Mainnet deployment, verified sources, and a session with your engineers.

Deliverable — deployment + docs

Sample — item mint hook

function mintItem(uint256 id, bytes calldata sig)
    external
    payable
{
    require(_verify(id, sig), "bad signature");
    _mint(msg.sender, id, 1, "");
    emit ItemMinted(msg.sender, id, block.number);
}

Every engagement ships with tests, deployment scripts and verified sources.
