Sonic Labs Launches Spawn, the First AI Platform for Building Web3 Apps From Natural Language

Sonic Labs, the team behind the high-performance Sonic blockchain, unveiled Spawn, the first purpose-built AI platform for creating full-stack Web3 applications from natural language. Previewed at ETH Denver 2026 with live demos and early access, ahead of a broader public release, Spawn turns plain English prompts into smart contracts and app infrastructure, enabling users to build and launch decentralized applications in minutes instead of weeks.

AI-powered builder tools have accelerated Web2 development, but Web3 has remained constrained by smart contract complexity, tooling fragmentation, and deployment overhead. Building a decentralized application today requires deep expertise across multiple domains: Solidity development, security auditing, compilation toolchains, blockchain deployment, wallet integration, and frontend engineering.

Purpose-built for Web3, Spawn solves this issue by translating natural language prompts into production-ready smart contracts, compiling and deploying them on-chain, and generating a fully integrated frontend with native wallet connectivity. From contract logic to UI and chain interaction, Spawn abstracts the full stack, enabling builders to move from idea to live dApp in minutes, without sacrificing on-chain functionality.

Samuel Harcourt, Core Contributor at Sonic Labs said “Web3 has always promised open access, but building on-chain has remained too complex for most people. With Spawn, we’re removing that barrier entirely. If you can describe your idea, you can deploy it. Simply describe your dApp in plain English, whether it’s a coin flip game where players wager S tokens or an NFT collection with a public mint, and Spawn handles the rest.”

From prompt to production, Spawn generates the smart contracts, compiles and deploys them to the Sonic testnet, and automatically builds a fully functional frontend wired directly to your on-chain logic. With Spawny, Spawn’s integrated AI agent, builders can iteratively modify contract logic, frontend components, and deployment configurations through a conversational development interface. What once required weeks of smart contract development and full-stack engineering now takes minutes, with no prior blockchain experience required.

Built natively on the Sonic blockchain, Spawn deploys applications directly to a high-performance, EVM-compatible network purpose-built for speed, scalability, and cost efficiency. With near-instant finality and ultra-low transaction fees, Sonic provides the performance layer required to support the next generation of interactive, user-facing Web3 applications. From on-chain games and NFT collections to DeFi protocols, DAOs, and payment systems, Spawn empowers builders to launch fully functional, production-ready Web3 applications in minutes.

At ETHDenver, Sonic Labs put Spawn to the test with a live demonstration by generating a fully playable Snake game, complete with an on-chain leaderboard, from a single natural language prompt. The game is live now at snake.soniclabs.com, where ETH Denver attendees competed for the top spot on the on-chain leaderboard and to win exclusive Sonic merch, showcasing in real time how Spawn turns prompts into fully deployed, interactive Web3 applications.
