Fiat on- and off-ramp infrastructure supporting 136+ assets across 45+ networks
Transak is a fiat on-ramp and off-ramp provider for wallets, exchanges, neobanks and other financial applications. Its infrastructure supports 136+ assets across 45+ networks, and the company says more than 600 platforms use its products to reach 10M+ users.
Transak is led by co-founder and CEO Sami Start. Its August 2025 strategic round raised $16 million from Tether and IDG Capital. Gobi Partners invested in the company in April 2026. The company reports money transmitter licenses in 11 U.S. states and Digital Currency Exchange approval in Australia.
Applications can add a hosted widget, a Web SDK, a mobile WebView or a white-label API. The API lets an application control the checkout interface, while the widget provides a pre-built flow. Users can buy crypto with cards, bank transfers, SEPA or Apple Pay, depending on the market and asset.
Transak also handles crypto-to-fiat off-ramps that settle into a user's bank account. Its virtual-account product gives each user a named virtual bank account and a dedicated wallet address. Inbound wires can settle as USDC, USDT or another supported token. KYC is available through pre-built flows. KYC Reliance can reuse an existing verification through Sumsub.
Transak says its quoted-rate spread is 0% to 2.5%, depending on currency volatility. Headless Cards and Apple Pay support one-tap checkout in supported markets.
The service describes its coverage as global, with licensed on-ramps and off-ramps across the United States, United Kingdom, Australia, Canada and other markets. Availability varies by transaction, including by country, payment method and asset. KYC applies to the relevant flows and can be handled inside the application.
Transak achieved SOC 2 Type 2 compliance in March 2024. It reported money transmitter licenses in 11 U.S. states during 2025. These licenses enable wire transfers and bank-to-wallet stablecoin deposits in those states. The company reported a security incident on October 21, 2024, which affected 1.14% of its user base.
Its model leaves applications dependent on Transak, banking partners and local payment providers. Card fees and quoted spreads can raise the cost of small purchases, while payments can fail or be reversed. Regional licensing creates gaps between markets. Supported assets and networks also differ by route.
Transak offers fiat on- and off-ramp infrastructure for financial applications, but payment spreads, regional licensing gaps and a 2024 security incident remain material trade-offs.
Transak is a payments infrastructure provider for wallets, exchanges, neobanks and other financial applications. Its main strength is breadth: the service lists 136+ assets across 45+ networks and supports cards, bank transfers, SEPA and Apple Pay. It offers both on-ramp and off-ramp flows. Coverage still depends on the user's country, payment method and asset.
The developer offering is another clear strength. Partners can use a hosted widget, Web SDK, mobile WebView or white-label APIs, with webhooks and KYC Reliance for existing verification. Virtual Account Payments add named virtual IBANs and dedicated wallet addresses.
Transak says its quoted rate uses market pricing plus a spread of 0% to 2.5%, depending on currency volatility. The quoted spread is one part of the stated pricing. KYC is built into the service, with regional requirements varying by flow. Users also face failed-payment and reversal risks.
Transak says it holds money transmitter licenses in 11 U.S. states and has Digital Currency Exchange approval in Australia. It also reports licensed on- and off-ramps across the U.S., U.K., Australia, Canada and other markets. Its track record includes 600+ integrated platforms and 10M+ users. Tether and IDG Capital provided a $16 million strategic round in August 2025, while Gobi Partners invested in 2026.
Security has both a compliance milestone and a reported incident. Transak achieved SOC 2 Type 2 compliance in 2024, but a security incident on October 21, 2024 affected 1.14% of its user base.
