overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
From a 2-week MVP to a full protocol suite, we deliver battle-tested code with a focus on security and scalability.
- Security-First Development: Every contract undergoes internal review and is built for formal verification. We integrate with
SlitherandMythXfrom the start. - Full Lifecycle Support: We handle deployment, upgradeability planning (using
TransparentorUUPSproxies), and frontend integration. - Measurable Outcomes: Typical projects see a 40% reduction in gas costs and launch with zero critical vulnerabilities post-audit.

Frequently Asked Questions
Get clear answers on how we build secure, scalable protocols that unify digital asset commerce across virtual worlds.
An Inter-Metaverse Marketplace Aggregator is a protocol that connects disparate NFT and digital asset marketplaces across different virtual worlds (e.g., Decentraland, The Sandbox, Otherside) into a single, seamless interface. You need one to increase liquidity, reduce user friction, and capture cross-platform trading volume. Instead of users checking multiple isolated markets, your platform becomes the go-to hub, offering better prices, broader discovery, and a unified wallet experience, directly driving user acquisition and transaction fees.
