Sorted Wallet: A 10MB Crypto Wallet Built for Feature Phones and the Unbanked

The wallet focuses on people who are unbanked or underbanked, especially in regions where feature phones remain common and mobile money services are widely used.

Key capabilities include:

• Storing and sending Bitcoin (BTC) and USDT stablecoins
• Receiving cross‑border remittances from anywhere in the world
• Paying bills or buying airtime directly from a crypto balance
• Cashing out to mobile money services such as M‑Pesa

Because the app is extremely small and optimized for low‑power devices, it can run on older smartphones and feature phones running lightweight operating systems.

The $4.4 Million Seed Round

Sorted Wallet announced a $4.4 million seed funding round aimed at scaling the platform in emerging markets.

The round included:

• $3.4 million in equity financing co‑led by Tether and Gnosis
• $1 million in strategic support from Vox Solutions
• Additional participation from angel investors including Movement and Angel Invest Group

The funding is intended to expand the wallet’s operations in regions where smartphone penetration is lower but mobile money and cross‑border remittances are widely used.

How a 10MB Wallet Works on Feature Phones

Most crypto wallets are designed for powerful smartphones. Sorted Wallet instead targets devices with limited storage, memory, and connectivity.

Several design choices make that possible.

Lightweight architecture

The wallet’s installation size is roughly 10MB, allowing it to run on low‑storage devices and slow networks.

Feature‑phone compatibility

Sorted Wallet supports devices running KaiOS, a lightweight mobile operating system widely used on smart feature phones.

These devices often have physical keypads and limited computing power, so the wallet interface and functionality are optimized for simpler hardware.

Non‑custodial crypto access

Users maintain control of their funds directly within the wallet instead of relying on a custodial exchange or bank‑like service.

This allows users without traditional financial accounts to store and transfer digital assets using only their phone.

Lightning Network integration

Sorted Wallet has integrated the Breez SDK, enabling Bitcoin Lightning payments inside the wallet.

Lightning allows:

• Faster Bitcoin transactions
• Lower fees for small payments
• More practical everyday usage on basic devices

This is particularly important for remittances and micro‑payments in developing markets.

Where Sorted Wallet Is Gaining Traction

Sorted Wallet focuses on emerging markets where feature phones remain widespread and banking access is limited.

Reports indicate traction across several African countries, including Nigeria, Tanzania, and Madagascar, with additional activity across other parts of the continent.

The wallet also supports mobile money integrations such as M‑Pesa in Kenya and other regional payment systems, allowing users to convert digital assets into local mobile money balances.

According to reports tied to the funding announcement, the app has reached around 500,000 downloads, with particularly fast growth in markets like Nigeria.

Why Tether and Gnosis Invested

The investment fits into a broader effort to expand stablecoin usage in real‑world payments and remittances.

USDT is widely used in countries with volatile local currencies or limited banking infrastructure. By backing a wallet designed for basic phones, investors gain a distribution channel that can reach users who are often excluded from traditional fintech products.

Sorted Wallet’s approach targets:

• Cross‑border remittances
• Dollar‑denominated savings via stablecoins
• Everyday payments using mobile devices

For stablecoin issuers like Tether, enabling those use cases on inexpensive phones could significantly expand the potential user base.

Why Feature Phones Still Matter

Despite global smartphone growth, hundreds of millions of people still rely on feature phones or low‑powered devices, particularly in parts of Africa and South Asia.

Traditional crypto apps rarely support these devices. Sorted Wallet’s strategy is to build infrastructure for that overlooked segment—bringing digital assets to users who may only have a keypad phone and mobile data.

If adoption continues to grow, lightweight wallets like this could become an important bridge between mobile money ecosystems and blockchain‑based payments.
