WHAT WE BUILD
What does your Web3 game need?
Smart Contract Development
Solidity contracts for NFT minting, marketplace logic, staking, and reward distribution. OpenZeppelin standards, reentrancy guards, and access controls built in. Audit-ready from the first line of code.
NFT Minting & Marketplace
ERC-721 and ERC-1155 contracts with on-chain metadata. In-game or standalone marketplace with listing, bidding, and royalty enforcement. Built on OpenSea SDK or custom contract depending on requirements.
Play-to-Earn Mechanics
P2E systems designed to survive past launch. Controlled token emission, burn mechanics on major transactions, and real utility that makes tokens worth holding. Not farming.
Token Economy Design
Dual-token models, governance tokens, staking vaults, and liquidity pair management. We've seen what collapsed in 2022. We design economies with sinks first and emissions second.
On-Chain Game Logic
Tournament brackets with on-chain prize distribution, loot tables, crafting systems that burn assets to mint higher-rarity ones, and guild contract systems for multi-player coordination.
Web3 Wallet Integration
MetaMask, WalletConnect, and Magic Link email wallets for players who don't want self-custody. Multi-chain support for Ethereum, Polygon, Solana, and Immutable X. Requiring MetaMask on signup loses 90% of potential players.

"Afnexis built our smart contract stack and P2E mechanics from scratch. They flagged 3 tokenomics issues before we launched that would have killed the game in month 2. Solid team."

HOW IT WORKS
From call to production in weeks.
Economy Design
We design the token model, emission schedule, and sink mechanics before writing a contract. This is where most Web3 games fail. We fix it at the architecture stage.
Smart Contracts
Solidity or Rust contracts written to OpenZeppelin standards. Testnet deployment, internal review, and third-party audit coordination before mainnet.
Game Integration
Unity or Unreal client connected to contracts via Web3 SDK. Wallet onboarding, NFT inventory, and marketplace UI. Mainnet deployment with gas relay if needed.
PRICING
Fixed price. No surprises.
Ranges from 50+ real projects. Milestone billing. No retainers.

FAQ
Quick answers.
What blockchain should we build on?
Depends on transaction volume and gas cost tolerance. Ethereum for maximum trust. Polygon for low gas with Ethereum security. Immutable X for zero gas fees for players. Solana for high throughput. We recommend after reviewing your expected transaction volume.
Are your smart contracts audited?
We write contracts to OpenZeppelin standards with reentrancy guards and proper access controls. We coordinate with third-party auditors like Certik or Hacken for production contracts handling player funds. Audit costs are separate from development.
How do you handle player onboarding without MetaMask?
Magic Link creates a wallet tied to an email address. Players who want self-custody can migrate later. We support MetaMask, WalletConnect, Phantom, and Magic Link. Players who don't want crypto friction still play.
What went wrong with play-to-earn in 2022?
Pure token-farming games collapsed when player growth stopped. Emissions exceeded demand and tokens crashed. The surviving games focus on digital ownership of scarce assets and burn mechanics. We design economies with sinks first and emissions second.
