NFT Marketplace

Project: Ghostmarket

Problem:

Ghostmarket needed to expand beyond Phantasma to other chains (ETH, BSC, Polygon, Avalanche) to be a major player amoung the NFT marketplaces, while maintaining contract security and development efficiency.

Solution:

Migrated Opensource codebase from Truffle to Hardhat for modern testing/deployment
Across multiple mainets deployed:
ERC721/ERC1155 contracts
Custom Marketplace contracts
Relayer contracts for nft market makers
Built a SDK kit to interact with the smart contracts of the marketplace

Impact:

Very fast contract iterations thanks to modern development frameworks
Multichain support across major chains
First Multichain marketplaces on Avalanche
