SolScript vs Seahorse: Choosing a High-Level Solana Language

Both SolScript and Seahorse let you write Solana programs without Rust. SolScript uses Solidity syntax, Seahorse uses Python. Here's how to choose between them.

Key Takeaways

  • SolScript uses Solidity syntax -- ideal for the 200,000+ Ethereum developers worldwide.
  • Seahorse uses Python syntax -- ideal for developers with Python backgrounds.
  • Both generate Anchor/Rust code, so output quality and performance are comparable.
  • SolScript has a browser-based WASM playground for instant compilation without setup.

Which Should You Choose?

Choose SolScript If

  • You know Solidity from Ethereum development
  • You want to migrate ETH contracts to Solana
  • You want a browser-based development playground
  • You prefer the ERC20/ERC721 contract patterns
  • You want both Anchor and direct BPF output

Choose Seahorse If

  • You're most comfortable with Python syntax
  • You don't have Ethereum/Solidity background
  • You prefer Python-style patterns and idioms
  • You're coming from data science or scripting backgrounds

Frequently Asked Questions

What is the difference between SolScript and Seahorse?
SolScript uses Solidity syntax and targets Ethereum developers migrating to Solana. Seahorse uses Python syntax and targets Python developers. Both compile to Anchor/Rust code for Solana.
Which has a larger developer community?
Solidity has a significantly larger developer community than Python in blockchain development. There are over 200,000 Solidity developers globally, making SolScript's approach accessible to a larger pool of developers.
Can I use both SolScript and Seahorse in the same project?
Both tools generate standalone Anchor programs. You can deploy programs from either tool on Solana and have them interact via Cross-Program Invocations (CPIs).
