thirdweb

To empower developers to easily create decentralized internet products and serve them to billions of users.

thirdweb is a full-stack development platform that makes building web3 applications accessible to any developer. The company provides frontend, backend, and on-chain tools for creating apps and games that work across EVM-compatible chains and Solana. Over 100,000 developers use the platform monthly, with more than 1 million unique wallets interacting with thirdweb contracts on mainnet. Major companies like Shopify, AWS, Coinbase, Circle, and Animoca Brands rely on thirdweb to power their applications. The platform abstracts blockchain complexity through pre-built smart contracts, wallet infrastructure, and comprehensive SDKs, allowing teams to focus on user experience rather than infrastructure. Beyond traditional web3 apps, thirdweb is expanding into AI integration, building tools that enable autonomous agents to read on-chain data and execute transactions.

Products

The platform offers a comprehensive suite of web3 development tools. Core products include pre-built, audited smart contracts and customizable modular contracts for rapid deployment. Wallet infrastructure spans In-App Wallets, Ecosystem Wallets, and Account Abstraction to streamline user onboarding. The Universal Bridge and Payments APIs enable cross-chain token swaps and fiat-to-crypto purchases. Enterprise-grade infrastructure includes Engine Cloud for scalable transaction management and Insight for blockchain data querying. Recent additions include AI tools like the Nebula model and MCP Server for building autonomous agents. SDKs support React, Unity, Unreal Engine, and React Native across consumer apps, gaming, and DeFi use cases.

Funding

thirdweb has raised $29 million across two funding rounds. The company secured a $5 million seed round in December 2021 with angel investors including Gary Vaynerchuk and Mark Cuban. In August 2022, thirdweb completed a $24 million Series A led by Haun Ventures at a $160 million valuation. Strategic participants included Coinbase Ventures, Shopify, and Polygon. The company has used this capital to expand its ecosystem and recently acquired platforms like Yup and Web3Onboard in early 2025.
