Transak

Transak provides payments infrastructure for Web3 apps that want embedded fiat on ramp and off ramp flows inside wallets, games, marketplaces, and other products.

Its official documentation highlights prebuilt widgets, SDKs, and whitelabel options that let partners support crypto purchases with cards, bank transfers, and local methods, then enable cash outs back to fiat as well.

The platform is presented as an onboarding and exit layer that handles compliance, risk controls, and user flow complexity for integrators working across many chains.
