Thirdweb
Thirdweb is a Wallets & Dev Infrastructure company founded in 2021 and based in San Francisco, United States. It has raised $29M in total funding, most recently a Series A in 2022 at a $160M valuation.
Founded in 2021 by Furqan Rydhan and Steven Bartlett, Thirdweb gives developers a full-stack web3 SDK that reduces the time and cost of building on-chain applications. Its tools cover smart-contract deployment, embedded and account-abstraction wallets, fiat and crypto onboarding, and cross-chain payments. Thirdweb has expanded into AI-agent infrastructure, including x402 support across its SDK and a gasless facilitator that lets agents and APIs discover and pay for services on-chain. It raised a $24M Series A in 2022 at a $160M valuation led by Haun Ventures.
Thirdweb lowers the floor for building on-chain apps and wallets, and its x402 and AI-agent tooling positions it at the front of machine-to-machine crypto payments.
