Multi-chain NFT aggregation
VC-backed, production scale
Overview
A VC-backed multi-chain NFT platform with integrated wallet, enabling discovery, minting, trading, and staking across multiple marketplaces. Komet set out to make DeFi and NFTs approachable through a secure multi-chain wallet, and UniDev's work as Web3 developer centered on the NFT infrastructure and account abstraction layer that made it actually work under the hood.
Client results
- Unified discovery across marketplaces
- Better UX at serious transaction volume
- Investor-grade product credibility
Who this is for
- NFT traders and collectors
- Web3 startups raising and scaling
- Teams needing wallet + marketplace in one
The problem
- Fragmented NFT marketplaces across chains
- High transaction fees and poor UX bottlenecking adoption
- Complex wallet and multi-chain interactions for newcomers
- Lack of real-time NFT insights and alerts
What we built
- NFT smart contracts across ERC721, ERC1155, and ERC721A, tuned for gasless minting, drops, and airdrop mechanics
- ERC-4337 account abstraction giving users one consistent wallet address across chains instead of one per network
- Transaction bundling contracts and cross-chain execution improvements tied to the Berry Protocol integration
- A simplified transaction flow that cuts friction for Web3 newcomers
