PROVEN METHODOLOGY
Our Development & Integration Process
A structured, security-first approach to building and deploying interoperable avatar protocols. We deliver production-ready systems, not proof-of-concepts.
01
Architecture & Protocol Design
We design your core avatar protocol using standards like ERC-6551 (Token-Bound Accounts) and ERC-721, ensuring seamless asset portability and composability across virtual worlds. This establishes the foundation for true cross-metaverse identity.
ERC-6551
Core Standard
2-3 weeks

02
Smart Contract Development
Secure, gas-optimized contract suite built in Solidity 0.8+. Includes avatar minting, upgrade logic, and cross-chain state management. All contracts follow OpenZeppelin best practices from day one.

Common Questions on Cross-Metaverse Avatar Protocol Development
Get clear, technical answers on timelines, security, and integration for your cross-metaverse avatar project.
A standard cross-metaverse avatar protocol with core interoperability features (ERC-6551/ERC-4337 integration, 2-3 target chains) typically deploys in 4-6 weeks. Costs are project-based, ranging from $45K to $120K+, depending on avatar complexity, number of supported metaverse platforms (Decentraland, The Sandbox, etc.), and custom features like dynamic NFT traits or AI integration. We provide a fixed-price quote after a technical scoping session.
