Secure, production-ready smart contracts built by Web3 specialists.
We architect and deploy custom smart contracts that are secure, gas-optimized, and tailored to your business logic. Our development process includes:
- Formal verification and multi-audit cycles before mainnet deployment.
- Gas optimization to reduce user transaction costs by up to 40%.
- Upgradeable patterns using
ProxyandDiamondstandards for future-proofing.
From tokenomics (
ERC-20,ERC-721,ERC-1155) to complex DeFi primitives, we deliver battle-tested code.
Our engineers specialize in Solidity 0.8+, Vyper, and Rust (for Solana), implementing OpenZeppelin best practices. We ensure your contracts are not just functional, but enterprise-grade.
Avatar Identity & Reputation Systems
Frequently Asked Questions
Answers to common technical and commercial questions about our avatar identity and reputation system development services.
A complete, production-ready avatar identity system with on-chain reputation typically deploys in 6-10 weeks. This includes a 2-week discovery and design phase, 4-6 weeks of core development (smart contracts, SDK, UI), and 2 weeks for security audits and final integration. For simpler integrations using our modular components, deployment can be as fast as 2-3 weeks.
