Smart contracts: what they are and how they work.
Get smart about smart contracts

As people pay more attention to web3, knowledge of the space and how it fundamentally functions will become an invaluable toolset far into the future. 

And that means understanding the building blocks that make web3 smooth and transparent. 

So, let’s expand that knowledge base and set you up for success in this decentralized future we’re living in. 

If you've been keeping up with the latest buzzwords in the tech industry, you've probably heard of "smart contracts." But what exactly are they, and why should you care? 

In this blog post, we'll break down the basics of smart contracts, how to deploy them, and how they change how we do business in web3. 

What are smart contracts?

Smart contracts are computer programs that automatically enforce the terms of a contract. They're built using blockchain technology, which provides a secure and decentralized way to store and process data. By using smart contracts, businesses, and individuals can automate complex transactions and eliminate the need for intermediaries like lawyers and banks.

How do smart contracts work?

Smart contracts use "if-then" statements to enforce the terms of an agreement. For example, if Party A sends 10 tokens to Party B, then Party B will release a digital asset to Party A. Once the conditions are met, the smart contract automatically executes the transaction without manual intervention.

Smart contracts are stored on a blockchain, which acts as a tamper-proof ledger of all transactions. This means that once a smart contract is deployed, it can't be altered or deleted, providing a high level of transparency and immutability.

Benefits of smart contracts

There are many benefits to using smart contracts, including but not limited to:

Efficiency and cost savings

Smart contracts can automate many manual processes, reducing the time and costs associated with traditional contract management. 

Use-case example: Streamlined Supply Chain Management

In the global supply chain, smart contracts can be used to improve efficiency and reduce costs by automating processes, such as payment and delivery confirmations. By integrating smart contracts into a supply chain management system, companies can automatically execute contractual agreements between multiple parties, eliminating the need for manual intervention and reducing the likelihood of errors or disputes. This streamlined approach speeds up the process and leads to significant cost savings in labor, administrative expenses, and dispute resolutions.

Transparency and immutability

Because smart contracts are stored on a blockchain, all parties can see the contract terms and the transaction's outcome. This provides high transparency and immutability, reducing the risk of fraud and disputes.

Use-case example: Transparent Charity Donation Tracking

Smart contracts can be employed to create a transparent and accountable system for tracking charitable donations. By leveraging blockchain technology, donations can be recorded and tracked in real-time, giving donors a clear view of how their contributions are utilized. Smart contracts can also automatically distribute funds to the intended recipients or projects based on predefined criteria, ensuring that the donations are used as intended. This level of transparency and immutability fosters trust between donors and charitable organizations while improving overall accountability.

Decentralization and trustlessness

Smart contracts are decentralized, meaning they don't rely on a central authority to enforce the terms of the contract. Instead, they rely on the network's consensus, which provides a high level of trustlessness and security.

Use-case example: Decentralized Identity Management

Smart contracts can facilitate the creation of a decentralized identity management system, empowering individuals to control and manage their digital identities without relying on centralized authorities. Users can store their personal information and credentials on a blockchain, with smart contracts governing access to the data. Users can grant or revoke access to specific parties, ensuring their personal information remains secure and controlled. This trustless approach to identity management enhances privacy and reduces the risk of identity theft and data breaches.

Important note on auditing your smart contracts

While smart contracts offer many benefits, risks, and challenges still exist—one of the most important aspects being code vulnerabilities and security risks.

Smart contracts are only as secure as the code they're built on. If there are vulnerabilities in the code, attackers can exploit them to steal funds or disrupt the network. So ensure your smart contract is thoroughly audited and tested before deploying it.

Getting started 

If you're interested in using smart contracts, here are some steps to get started:

Choosing a blockchain platform

Many blockchain platforms support smart contracts. However, each platform has its strengths and weaknesses, so it's necessary to research and choose the one that best suits your needs.

Writing and testing your smart contract

Once you've chosen a blockchain platform, it’s time to write and test your smart contract. This can be done automatically using RECUR Builder, or manually with programming languages like Solidity or Vyper. Again, many online resources and tutorials are available to help you get started.

Deploying your smart contract

Once your smart contract is written and tested, you can deploy it to the blockchain platform of your choice. This will often require you to pay a fee in cryptocurrency, so be sure to factor that into your budget.

Using your smart contract

Once your smart contract is deployed, you can start using it to automate transactions and enforce the terms of your agreements. Be sure to monitor your smart contract regularly to ensure that it's working as intended.


Smart contracts are a powerful tool for automating complex transactions. While there are risks and challenges to consider, the benefits of smart contracts are clear: increased efficiency, transparency, and decentralization. If you're interested in using smart contracts, be sure to do your research, choose a reputable blockchain platform, and ensure that your smart contract is appropriately audited and tested before deploying it.

As with any new technology, there's a learning curve involved. But by taking the time to understand how smart contracts work and how they can benefit your business, you'll set yourself up to stay ahead of the curve as web3 adoption skyrockets.
