❓What is Transak Off-Ramp Stream?

Transak Off-Ramp Stream is the latest innovation in crypto off-ramping, allowing users to receive fiat directly into their bank accounts/cards with just one click. As simple as sending crypto from one wallet to another, Transak Stream makes moving between crypto and fiat seamless and intuitive.
With Transak's APIs, apps and platforms can build Streams into their workflows, enabling smooth, one-click flows for their users. From remittances to payroll and e-commerce payouts, Transak Stream simplifies crypto-to-fiat automation for both businesses and users.

Example: A user with a Web3 wallet wants to withdraw $1000 USDC. All they have to do is tap the "withdraw to bank" button directly within their wallet. Just like transferring funds between wallets, the USDC is seamlessly sent to their dedicated Transak wallet address. Within minutes, the equivalent fiat is deposited into their bank account—no need to open additional apps or deal with the Transak interface. This smooth, hassle-free process redefines the off-ramp experience, making it incredibly user-friendly while giving wallet partners a competitive advantage.
