Summary:

• PiggyVest now supports USDT and USDC deposits into Flex Dollar from external crypto wallets.
• Users can deposit across Ethereum (ERC-20), Tron (TRC-20), Polygon, Arbitrum, Solana, and BNB Chain.
• The integration connects PiggyVest’s mainstream savings ecosystem with Web3 and stablecoin infrastructure, potentially making dollar savings more accessible to existing crypto users in Nigeria.

PiggyVest has introduced stablecoin deposits for its Flex Dollar wallet, allowing users to fund their dollar savings with USDT and USDC directly from external crypto wallets across multiple blockchain networks.

PiggyVest unveiled the new feature on Saturday, September 26, 2026, during PiggyVest’s OpenHouse 2026 at the National Theatre in Lagos, where the fintech showcased new products and experiences to its community.

According to the new in-app deposit flow seen by Crypto Africa News, Flex Dollar users can now select either USDC or USDT when generating a crypto deposit address.

The available networks supported include Ethereum (ERC-20), Tron (TRC-20), Polygon, Arbitrum, Solana, and BNB Chain, giving users several options for moving stablecoins into their Flex Dollar accounts.

PiggyVest’s in-app notice tells users that they must send the selected stablecoin from a wallet they control to the deposit address generated for them. It also warns that sending the wrong asset or using an unsupported network can result in permanent loss of funds.

The deposit address generated for a user is described as permanent and reusable for future Flex Dollar funding.

A New Funding Route for Flex Dollar

The stablecoin integration expands the ways PiggyVest users can fund their dollar wallets.

Before the new feature, users could purchase dollars through their Flex Naira balance or use a Naira debit card. PiggyVest also provides users with a dedicated Flex Dollar Virtual Account Number (VAN) that can receive USD through ACH or domestic wire transfers.

The VAN is provided through PiggyVest’s partnership with Oval Technologies Ltd, also known as Graph Finance, which PiggyVest says is licensed by the Central Bank of Nigeria as an International Money Transfer Operator.

ACH and domestic wire deposits can take between one and three working days to process, according to PiggyVest.

Stablecoin deposits introduce a fundamentally different funding route because users can now move dollar-pegged digital assets from an external crypto wallet directly into the PiggyVest ecosystem.

This could be particularly relevant for Nigerians who already hold USDT or USDC but previously had to convert their stablecoins into fiat before accessing a traditional dollar savings product.

How the New Stablecoin Deposit Works

According to the process shown in PiggyVest’s new interface, users can choose between USDC and USDT before generating their deposit address.

Multiple-network support means that a user holding USDT on Tron, for example, would need to ensure that the PiggyVest deposit address generated for the transaction supports the same network before sending the funds.

This is particularly important because stablecoins such as USDT and USDC exist across multiple blockchains, and sending an asset through an incompatible network can result in funds becoming unrecoverable.

Flex Dollar Meets Stablecoins

Flex Dollar is PiggyVest’s dollar savings product, designed to allow users to save, invest, and transfer funds in US dollars. PiggyVest says Flex Dollar funds are invested in dollar-denominated fixed-term investments and Eurobonds, with the underlying investment products managed by asset managers regulated by Nigeria’s Securities and Exchange Commission.

The addition of stablecoin deposits therefore does not turn Flex Dollar itself into a self-custodial crypto wallet. Instead, stablecoins become another funding rail into an existing dollar savings product.

A user sending USDT or USDC to PiggyVest is using blockchain infrastructure to fund a Flex Dollar account, while the resulting Flex Dollar balance remains within PiggyVest’s financial product structure.

According to PiggyVest, Flex Dollar can earn interest, with rates up to 6% per annum, according to a June 2026 PiggyVest article.

What This Means for the Web3 Space in Nigeria and Africa

The significance of this development goes beyond another funding option inside a fintech app.

PiggyVest has built a large consumer-facing financial platform around saving and wealth management. Bringing USDT and USDC deposits into Flex Dollar means blockchain-based dollar assets are now being connected directly to a mainstream savings environment used by Nigerians.

For members of the PiggyVest community who already hold stablecoins, the development could reduce one layer of friction between their crypto holdings and conventional dollar savings.

Instead of necessarily converting USDT or USDC into naira first, users can now move supported stablecoins directly into the Flex Dollar funding flow, subject to PiggyVest’s requirements and the supported networks.

It also creates an interesting bridge between Web2 fintech infrastructure and Web3 financial rails.

Stablecoins have increasingly become a major part of digital-dollar activity across emerging markets because they can move over blockchain networks without relying on conventional banking rails for every transaction.

By accepting USDT and USDC, PiggyVest is effectively allowing its users to interact with that infrastructure without requiring them to manage the entire process through a crypto exchange.

For Nigeria’s Web3 ecosystem, the move could also expose a much broader audience to practical stablecoin use. A PiggyVest user does not necessarily need to be an active crypto trader to encounter USDT or USDC anymore. The assets can instead become part of a familiar savings workflow.

The potential impact extends beyond Nigeria. If similar integrations become more common among African fintechs, stablecoins could increasingly function as a bridge between blockchain-based dollar liquidity and traditional savings, payments and investment products across the continent.

At the same time, the rollout highlights the importance of user education and transaction safety. PiggyVest’s own warning about selecting the correct asset and network underscores one of the biggest challenges for mainstream crypto adoption: blockchain transactions are generally irreversible, and users can lose funds by sending the right asset over the wrong network.

For PiggyVest, the launch represents a notable expansion of Flex Dollar’s funding infrastructure. For Nigeria’s Web3 ecosystem, it is another indication that stablecoins are moving beyond crypto-native platforms and into products designed for everyday financial users.

And with USDT and USDC now sitting alongside naira purchases and traditional USD bank transfers as funding options, the boundary between Nigeria’s fintech and Web3 ecosystems is becoming increasingly connected.
