EXPERT GUIDANCE
Our Standardization Consulting Services
We provide actionable, protocol-specific consulting to define, implement, and scale your avatar metadata strategy. Our approach ensures interoperability, reduces development risk, and accelerates your time-to-market.
01
ERC-6551 & ERC-721 Integration Strategy
Architect token-bound accounts and dynamic NFT avatars with proven integration patterns. We design systems where ERC-6551 wallets own assets, enabling complex on-chain identity and interaction layers.
