In a major expansion, Transak has integrated its fiat on-ramp and off-ramp services into Tether’s Wallet Development Kit (WDK). This will help developers add fiat-to-crypto transactions to self-custodial wallets without building payment infrastructure from scratch.
The integration makes Transak an officially listed fiat payment provider within WDK, an open-source toolkit that enables developers to build self-custodial, multi-chain wallets. Users of wallets built with the toolkit can purchase cryptocurrencies using credit or debit cards, bank transfers, Apple Pay and Google Pay. They can also convert their crypto holdings back into fiat currency.
The partnership targets businesses building crypto wallets and other financial products. It addresses a key infrastructure challenge which is connecting users’ bank accounts with self-custodial wallets while managing payment integrations, regulatory requirements and local payout methods.
For developers, integrating fiat payment services can require establishing banking relationships, supporting different payment methods across markets and meeting applicable regulatory requirements. By incorporating Transak’s services, WDK-based wallet developers can access these capabilities without building a separate payment system.
Transak said its infrastructure supports more than 136 cryptocurrencies across 45-plus blockchains, alongside payment options including cards, bank transfers, SEPA, Faster Payments, wire transfers and regional payment methods.
Transak is now live as a fiat on-ramp and off-ramp in @WDK_tether.

“Every wallet eventually needs a way for people to fund with fiat and withdraw,” said Chandrasekar Kuppusamy, director of developer relations at Transak in a press release shared with Block of Fame. He added that the integration allows teams building on WDK to access payment methods and payout processing without developing the infrastructure independently.
As per its official blog, company also provides identity verification, fraud monitoring and compliance services through its regulated entities and payment infrastructure. According to Transak, more than 600 platforms already use its services.
The arrangement is designed to preserve the self-custodial nature of wallets built using WDK. Users retain control of their private keys, while Transak handles the fiat payment leg of transactions.
The integration also extends Transak’s reach across the businesses developing on Tether’s wallet infrastructure. Potential use cases include crypto wallets and exchanges, fintech companies and neobanks adding digital assets, as well as remittance and payroll platforms that need to facilitate payments in local currencies.
Now , the businesses building on other technology stacks can also integrate Transak separately through its partner account and API infrastructure.
Tether’s WDK provides developers with tools to build self-custodial wallets across multiple blockchain networks. Integrating fiat on- and off-ramps addresses a different part of the wallet development process: enabling users to move between traditional payment methods and digital assets.
Transak said its integration supports access to USD₮, Tether’s US dollar-pegged stablecoin, XAU₮, its gold-backed token, USA₮, and Bitcoin.
The announcement did not disclose financial terms for the partnership or provide figures on the number of WDK-based wallets expected to adopt Transak’s services.
For Transak, the integration adds another distribution channel for its business-to-business payments infrastructure, positioning the company to serve developers and financial platforms seeking to incorporate crypto transactions into their products without managing the full payment stack themselves.
