I’d like to take on this issue by building a robust NFT and in-game item marketplace contract using Soroban. I’ll design clean, extensible data structures for listings, offers, and escrow, implement secure buy/sell flows with marketplace fees and creator royalties, and add support for offers, counter-offers, and listing cancellations. I’ll also include helper functions for item discovery and filtering, plus comprehensive tests covering the full marketplace lifecycle. The end result will be a secure, well-tested contract ready for testnet deployment and real in-game trading scenarios.
