What Programming Languages Are Best Suited for Writing Secure Financial Smart Contracts?

Solidity is the most widely used language, primarily for the Ethereum Virtual Machine (EVM). It is specifically designed for smart contracts, but its flexibility can also lead to vulnerabilities.

Vyper is another Pythonic language for the EVM that prioritizes security and auditability by having a simpler, more restrictive design. Outside of the EVM ecosystem, languages like Rust (used by Solana and Polkadot) and Move (developed for Diem and now used by Aptos/Sui) are gaining traction.

They are designed with a strong focus on resource safety and preventing common bugs, making them well-suited for high-stakes financial applications.
