The problem: Solana has mass dev interest (17k+ active developers in 2025), but the Rust learning curve remains a 3-6 month barrier. Anchor helps, but you still need to grok ownership, lifetimes, and borrowing. Meanwhile, there are 30k+ Solidity developers who already know how to write smart contracts.
SolScript bridges that gap. You write this:
contract Token {
mapping(address => uint256) public balanceOf;
function transfer(address to, uint256 amount) public {
balanceOf[msg.sender] -= amount;
balanceOf[to] += amount;
emit Transfer(msg.sender, to, amount);
}
}
- Parser turns Solidity-like source into an AST - Type checker validates and annotates
- Two codegen backends: (1) Anchor/Rust output that goes through cargo build-sbf, or (2) direct LLVM-to-BPF compilation - Mappings become PDAs automatically, account structs are derived from your type system
What's supported:
- State variables, structs, arrays, nested mappings
- Events and custom errors
- Modifiers (inlined)
- Cross-program invocation (CPI)
- SPL Token operations - msg.sender, block.timestamp equivalents
Current limitations:
- No msg.value for incoming SOL (use wrapped SOL or explicit transfers) - No Token 2022 support yet (planned for v0.4) - Modifiers are inlined, so keep them small
The output is standard Anchor/Rust code. You can eject anytime and continue in pure Rust. It's a launchpad, not a lock-in.
Written in Rust. Ships with a VS Code extension (LSP, syntax highlighting, go-to-definition, autocomplete).
Install: cargo install solscript-cli
I'd love feedback on the language design, the compilation approach, or use cases I haven't thought of. Happy to answer questions about the internals.
