The ONDC Network Protocols simply allow buyer-side applications like eCommerce stores, travel sites, food delivery applications, and others to work agnostically with the seller-side participants like kiranas, B2B vendors, Logistic players, etc. to complete the transaction. The protocols maintain registries to allow participants onto the platform and also ensure the network policies are maintained by all parties. The ONDC Protocols are also built to tackle the 4 steps of the transaction, the discoverability of the products and services on the network, the transaction between parties, the fulfilment of the contract, and the post-sales arbitration.
