[Ethereum] Vyper vs. Solidity – benefits and differences


What are the benefits and differences of using Vyper over Solidity for smart contracts?

  • Are there any other differences besides syntax?
  • Are there any features for better developer experience (besides less typing with cleaner syntax)
  • Does Vyper provide better safety and security e.g. by stricter modifiers, defaults, and so on
  • Can Vyper and Solidity interact 100% – i.e. all Solidity functions can be called from Vyper and vice versa
  • What is the difference in toolchain maturity: static analyzers, code coverage tools, easy of installation, documentation and so on

I originally used Vyper for doing more complex math (specifically the curve integrals and inverse curve integrals for bonding curves), as it has a lot of securities built-in (such as over/underflow protection etc) but it can be quite a hassle. In my project, we ended up rewriting the math back into Solidity for continuity within our repo, and because the way that Vyper does square roots (the Babylonian method) was the same level of accuracy we got in Solidity anyway so there was no value add.

If you want to work with it just to try it out, go for it, but if you are looking for a specific reason to use it I wouldn't recommend unless you are going to be using some heavy math and want the Pythonic structure.
