Write smart contracts in TypeScript.
Skittles lets you write blockchain smart contracts using TypeScript — the language you already know. No new syntax to learn. Full IDE support with autocomplete, type checking, and go-to-definition. Under the hood, Skittles compiles to Solidity for compatibility with every EVM tool and blockchain.

Requires Node.js 22+.
npx skittles@latest init
npx skittles compileThis scaffolds a project with an example token contract and compiles it to build/.
import { address, msg, SkittlesEvent, Indexed } from "skittles";
export class Token {
Transfer: SkittlesEvent<{
from: Indexed<address>;
to: Indexed<address>;
value: number;
}>;
name: string = "My Token";
symbol: string = "TKN";
totalSupply: number = 0;
balances: Record<address, number> = {};
constructor(initialSupply: number) {
this.totalSupply = initialSupply;
this.balances[msg.sender] = initialSupply;
}
transfer(to: address, amount: number): boolean {
if (this.balances[msg.sender] < amount) {
throw new Error("Insufficient balance");
}
this.balances[msg.sender] -= amount;
this.balances[to] += amount;
this.Transfer.emit({ from: msg.sender, to, value: amount });
return true;
}
}This creates a simple token contract. Users can transfer tokens to each other, with balance checks and a Transfer event that logs activity on the blockchain.
