USDT Integration for Deposits, Withdrawals, and Spending
SFX has officially launched support for USDT (Tether) on its platform, marking a significant expansion of its stablecoin offerings. This integration allows users to deposit, withdraw, and spend USDT directly through the SFX app and its virtual Visa card. Previously, SFX primarily operated on USDC, facilitating low-cost global transfers and secure digital savings.
With the introduction of USDT, the most widely used stablecoin globally, SFX aims to provide enhanced flexibility, particularly in markets where USDT is prevalent in daily digital transactions.
Seamless USDT Transactions via Polygon Network
The new feature enables users to fund their SFX virtual card wallets with USDT through the Polygon network. This integration is designed to create a smoother and more accessible on-ramp for users worldwide, especially those who primarily use USDT for their digital asset transactions.
Users can also withdraw USDT back into their main SFX wallets, granting them complete control over fund management and storage. This two-way flow eliminates the need for external tools or converters, allowing for seamless transitions between spending and saving.

With this upgrade, SFX users can now spend their USDT balance through the app's virtual Visa card. This functionality extends to online shopping, subscriptions, global platforms, digital services, and contactless point-of-sale transactions. By enabling USDT-based spending across the Visa network, SFX aims to reduce friction in everyday payments and make stablecoin usage more practical in real-world scenarios.
Advancing Borderless Financial Inclusion
SFX states that the addition of USDT aligns with its core mission to provide accessible, borderless financial tools to users globally. Supporting both USDC and USDT enhances liquidity and offers customers more choices for saving, sending, and spending across international markets.
Stephen Udeh, the backend lead, emphasized that the USDT top-up feature is a significant advancement, offering users enhanced financial flexibility. He also highlighted that enabling instant USDT deposits directly into the SFX card account on the Polygon network removes barriers and provides a faster, more cost-effective, and secure method for funding everyday expenditures.
