    Smart contracts in decentralized blockchains can be used to implement neutral exchanges of goods, i.e. decentralized marketplaces. The marketplace actors can audit and trust the correctness and neutrality of the smart contract to act as a neutral third party. While many such marketplaces have been demonstrated, they are constrained to operate in a single blockchain. We present a decentralized marketplace spread over two blockchains, allowing separation of concerns between different blockchains and simultaneously increasing overall performance. The presented marketplace shows how smart lockers are rented on the platform, and how access tokens to the rented lockers are communicated securely in a manner that facilitates off-grid physical access.
