By developing a smart contract, I streamlined international payments for a global supply chain company. Traditionally, the process of international payment shortly depended on manual verification of invoices and their approval by different parties, which was lengthy and prone to errors. The categorical steps of the smart contract automated these processes. They ensured that, upon shipment confirmation—recorded on the blockchain ledger—a secure transfer of funds from the buyer initiates a tamper-proof escrow account on the blockchain. It is also registered on the blockchain ledger once the recipient has confirmed delivery. Only then is the payment to the vendor automatically triggered. These processes eliminated manual intervention and mountains of paperwork while also ensuring security and transparency in every transaction. The smart contract even reduced processing times and avoided possible errors through key stages.
