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.
Comparison
| Feature | SolScript | Seahorse |
|---|---|---|
| Language | Solidity | Python |
| Target audience | ETH developers | Python developers |
| Output | Anchor/Rust or BPF | Anchor/Rust |
| Browser IDE | Yes (WASM) | No |
| Auto PDA mapping | Yes | Yes |
| Direct BPF compilation | Yes (LLVM) | No |
| VS Code extension | Yes (with LSP) | Basic |
| Smart contract patterns | ETH-native (ERC20, etc.) | Pythonic |
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).
