Sending money between African countries is famously harder than sending it to London or New York. Fragmented banking systems, scarce correspondent relationships, and double currency conversions mean a Lagos-to-Accra transfer can cost more than the bus ticket between them.
Stablecoin rails collapse that entire stack: value moves on-chain in seconds, and only the first and last steps — local currency in, local currency out — touch the legacy system.
The old way vs. the new way
A traditional remittance hops through multiple intermediaries, each taking a cut and adding delay: your bank, a correspondent bank, an FX desk, the recipient’s bank. The World Bank puts average Sub-Saharan remittance costs around 7–8% — the highest of any region on earth.
The stablecoin route has three steps: convert local currency to USDC, send the USDC (seconds, fractions of a cent), and the recipient converts to their local currency or simply keeps digital dollars. Total cost on honest rails: typically 1–3% end to end.
Where phone numbers come in
The last usability wall was the address. Crypto addresses look like `7xKXtg2CW87...` — one typo and money is gone forever. It’s the single biggest reason people who need these rails most never use them.
Sawa’s answer: your phone number is your address. Pick a contact, type an amount in naira, cedis, or shillings, and send. Under the hood it’s USDC settling on-chain; on the surface it’s as familiar as airtime. If your recipient doesn’t have Sawa yet, the money waits for them to claim it when they sign up.
A real example
- —Ada in Lagos owes her supplier in Accra ₵2,000.
- —She buys the equivalent USDC with a naira bank transfer (1% + spread, quoted upfront).
- —She sends it to the supplier’s phone number. Settlement: seconds.
- —The supplier cashes out to mobile money in cedis, or keeps the USDC as dollar savings.
Total time: minutes. Total cost: a fraction of the legacy corridor. No forms, no queues, no “allow 3–5 business days.”
Try it with your own phone number
Sawa is a non-custodial wallet that turns phone numbers into payment addresses. Buy USDC with a bank transfer, send it like a text, cash out to bank or mobile money.
