How to Code a Smart Contract for Automating Supply Chain Payments

As technology continues to develop in the 21st century, it affects everything from communication to commerce. One of the more revolutionary and cutting-edge technologies is blockchain, which can be used to facilitate payments and automate services such as supply chain payments.

Coding a smart contract for automating supply chain payments is not an overly complicated process. But, it does need some knowledge of coding languages such as Solidity or JavaScript. Continue reading to learn more about smart contracts and their uses in automation, supply chain payments, and other industries.

What is a smart contract?

Smart contracts are self-executing digital agreements. They allow for the automatic enforcement of contractual obligations between two or more parties. They are stored on a blockchain and can be used to automate transactions and exchanges of data, money, assets, or other items of value in a secure, transparent way. 

This type of contract is often seen to be more reliable than traditional paper-based contracts because the terms are programmed into the code, eliminating any potential for misunderstandings or disputes. There is also a strong argument for its security because the code is stored on the blockchain and can’t be easily changed or manipulated. 

What is supply chain automation?

Supply chain automation is the use of technology to streamline and automate supply chain processes. This includes everything from inventory management and order fulfillment to transportation and logistics. Automation can help businesses to improve efficiency, reduce costs, and enhance customer satisfaction. 

How can smart contracts be used to automate supply chain payments?

Smart contracts can be used to automate supply chain payments securely and transparently. By encoding specific conditions into the smart contract, transactions can be automatically triggered when specific criteria are met, such as when goods are shipped or received. This eliminates the need for manual intervention and helps to ensure the timely payment of invoices and other financial obligations within the supply chain. 

What steps are involved in coding a smart contract for automating supply chain payments? 

Automating supply chain payments is one of the best use cases of a smart contract. To do this, your developers will need to meet certain criteria in the development process and follow best coding practices to ensure the contract’s accuracy and reliability. 

1. Identifying the terms.

The first step is to identify and define the terms and conditions that must be met to trigger payment. This can be any process within the supply chain, such as when goods are shipped or received. It’s important to be as specific as possible to avoid any ambiguity or misunderstandings later on.

Additionally, when defining the terms, be sure to include which parties are involved, what assets will be exchanged, when payments should be made, and any other conditions that need to be met for the payment to take place.

2. Drafting the smart contract.

Once the conditions for payment have been identified, they can be encoded into a smart contract. This contract must specify the identified terms of the agreement and determine how payments will be made automatically. 

To do this, your developer must create an ERC-20-compatible token. This token will be used to facilitate the payment process in your supply chain. Once you have created the token, you will need to write the code that outlines the conditions and function of your smart contract, as mentioned above.

3. Testing

Before deploying the smart contract onto a blockchain, it’s important to test it thoroughly to ensure it works as intended. This will help to avoid any errors or unforeseen issues later on. Many developers use a testnet blockchain to deploy and test their smart contracts before deploying them onto a mainnet.

4. Deployment

After you have written and tested your code, it will be deployed onto a blockchain network. You will need to choose a platform, such as Ethereum or Hyperledger, for your smart contract and the language you would like to use. Once deployed, it is ready for transactions to be executed on it. This will allow parties on both sides of the transaction to track progress, view payments, and more. 

With the smart contract in place, payments can now be automated in your supply chain. This means that funds are transferred from one party to another automatically and securely, eliminating the need for manual processes.

Other Use Cases of Smart Contracts

Aside from the supply chain, smart contracts can also be used in other areas, such as real estate, insurance, and healthcare. 

Real Estate

In the real estate industry, smart contracts can be used to automate rental payments and facilitate transactions between buyers and sellers. The advantage of using smart contracts in this industry is that they can help to streamline processes and reduce the need for paper documents. Transactions can also be performed faster and more efficiently with the security and automation that smart contracts provide.


Smart contracts can also be used in the insurance industry to automate claims processing and payments. For instance, it can be highly reliable in product liability insurance for supply chain businesses. By encoding specific conditions into the smart contract, insurers can trigger automatic payments when policyholders meet specific criteria, such as filing a claim or completing a health check. It can also be used at the beginning of the insurance process by identifying potential clients who qualify for an insurance policy.


Smart contracts are also useful in the healthcare industry. They can be used to automate medical record sharing and payments between providers. Plus, healthcare organizations can securely access patient data with permission from the patient and process payments quickly. 


Overall, smart contracts provide an efficient way to streamline supply chain payments. And, they can also automate other processes in various industries. With this technology in place, supply chain businesses can manage their finances better while providing an improved customer experience. But it is important to remember that smart contracts require regular maintenance and updates to ensure they remain secure and effective.
