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).
