Solidity vs Rust: Which Is the Better Language for Smart Contracts?

Posted on

When it comes to developing smart contracts, choosing the right programming language is crucial. Solidity vs Rust are two of the most popular languages used for writing smart contracts on blockchain platforms such as Ethereum and Polkadot. In this article, we’ll take a closer look at the differences between Solidity and Rust and help you decide which one might be better suited for your needs.


Solidity is a contract-oriented programming language that was specifically designed for writing smart contracts on the Ethereum platform. It is a statically typed language with syntax similar to that of JavaScript and is widely used for creating decentralized applications (DApps) on the Ethereum blockchain.

One of the main advantages of Solidity is its ease of use. It has a relatively simple syntax and is easy to learn, even for developers who are new to blockchain development. Solidity also has a large community of developers who are constantly contributing to its development, which means that new features and updates are regularly released.

However, one of the drawbacks of Solidity is its security. Smart contracts written in Solidity are prone to vulnerabilities, such as reentrancy attacks and integer overflows. To mitigate these risks, developers need to be well-versed in secure coding practices and must thoroughly test their contracts before deployment.


Rust is a systems programming language that is designed to be fast, reliable, and secure. It has gained popularity in the blockchain community due to its performance and safety features. Rust is a memory-safe language that prevents common programming errors such as null pointer dereferences and buffer overflows.

One of the main advantages of Rust is its safety. Smart contracts written in Rust are less prone to vulnerabilities than those written in Solidity. Rust also has a large and growing community of developers who are constantly contributing to its development.

However, one of the drawbacks of Rust is its complexity. The language has a steep learning curve and is more difficult to learn than Solidity. This means that developers who are new to Rust may need to invest more time and effort into learning the language before they can start writing smart contracts.

Solidity vs Rust: The Main Differences in Code

There are several key differences in the code between Solidity and Rust. For example:

  • Solidity is an object-oriented language, whereas Rust is a systems programming language.
  • Solidity is designed to run on the Ethereum Virtual Machine (EVM), whereas Rust is designed to run on any platform that supports the language.
  • Solidity uses a stack-based memory model, whereas Rust uses a heap-based memory model.

Pros and Cons

Solidity Pros:

  • Easy to use and learn.
  • Large community of developers.
  • Specifically designed for Ethereum.

Solidity Cons:

  • Prone to vulnerabilities
  • Relatively new language.
  • Limited interoperability with other blockchains.

Rust Pros:

  • Fast, reliable, and secure.
  • Memory-safe language.
  • Large and growing community.

Rust Cons:

  • Steep learning curve.
  • Not specifically designed for blockchain.
  • Less mature than Solidity.

Blockchain which supports each one

Solidity Support:

  • Ethereum (most used)
  • Ethereum-compatible blockchains (EVM)
  • Solana (with Solang compiler)

Rust Support:

  • Solana (most used)
  • Polkadot, NEAR and Oasis


In conclusion, both Solidity and Rust are excellent languages for developing smart contracts. Solidity is well-suited for developers who are new to blockchain development and want an easy-to-use language that is specifically designed for Ethereum. Rust, on the other hand, is well-suited for developers who prioritize safety and performance and are willing to invest more.
