overview
CORE SERVICE
Smart Contract Development
Secure, audited smart contract development for DeFi, NFTs, and enterprise applications.
- Full Lifecycle Development: From initial design and
Hardhat/Foundrytesting to mainnet deployment and verification. - Security-First Approach: All contracts undergo internal audits and are prepared for third-party review by firms like CertiK or Quantstamp.
- Protocol Specialization: Custom logic for
ERC-20,ERC-721,ERC-1155, Automated Market Makers (AMMs), staking pools, and governance systems. - Measurable Outcomes: Achieve >95% test coverage and gas optimizations up to 40% versus initial implementations.
We deliver contracts that are secure by design, reducing time-to-audit and mitigating costly post-deployment vulnerabilities.

PROVEN METHODOLOGY
Our Development Process
A structured, transparent workflow designed to deliver a production-ready, secure, and scalable avatar SDK that accelerates your game's time-to-market.
01
Architecture & Design Sprint
We define your avatar's on-chain identity schema, cross-chain asset flow, and smart contract architecture in a collaborative 1-week sprint. This ensures a scalable foundation for your game's economy.
