Submission · Solana Frontier Hackathon 2026

Four seconds.
A fraction of a cent.
Karachi gets the money.

Pakistanis abroad send $30 billion home each year and lose over $1.5 billion of it to Western Union, MoneyGram, and bank wires. RemitSol replaces all of them with stablecoin rails on Solana — the same dollar, settled in under five seconds, for a cost rounded to zero.

The problem

A tax on the people who can least afford one.

Remittance fees are the most regressive tax in the global financial system. They fall hardest on workers earning $400 a month in Gulf labor camps trying to feed families they haven't seen in two years.

$30B
Sent home to Pakistan in 2024. The country's second-largest source of foreign exchange after exports. Over 11 million Pakistanis abroad send some portion of every paycheck back to a family member.

How it works

Three taps. No bank. No waiting.

The sender never has to explain "blockchain" to anyone. The recipient never has to learn what a wallet is. Both sides see a normal payment app.

i

Sender taps "send" in Dubai

Worker opens RemitSol on their phone, connects Phantom, types $200 USDC. Funds lock into an on-chain escrow address gated by a 6-digit claim code. Total time: 1.6 seconds.

ii

Code travels by WhatsApp

The 6-digit code is auto-shared to the recipient via WhatsApp — the app 97% of Pakistanis already check hourly. No SMS, no email, no friction. It looks like sharing a meme.

WhatsApp Share API · Universal Links
iii

Family withdraws in Karachi

Recipient opens the link, connects Phantom (or scans a QR), claims the funds, and off-ramps to JazzCash or Easypaisa. PKR lands in their mobile money account within seconds.

Real money. Real families. Real savings.

FEES SAVED BY PAKISTANI FAMILIES THIS MONTH
$0
Updating in real time as transfers settle on Solana devnet. Every dollar saved is a dollar that stays in a family's hands instead of going to a remittance company.
Why Solana

The first chain fast enough to feel instant.

Remittance is the textbook killer app for stablecoins on a high-throughput chain. Every constraint that killed prior crypto remittance attempts — speed, cost, UX — is solved at the protocol level on Solana.

400ms
Average Solana block time — the difference between a transfer and a "real-time payment."
$0.0001
Median transaction cost. Sending $20 costs the same as sending $20,000.
$5B+
USDC issuance on Solana as of 2024. Native, no bridges, no wrapped tokens.
0
Backend servers required. The Solana program is the database. Wallet is the auth.
Roadmap

A short, concrete path to mainnet.

This is not a five-year vision. The pieces that make this real already exist — Circle's devnet USDC, JazzCash and Easypaisa APIs, Pakistan's State Bank Virtual Asset framework published in 2025. The work left is integration, not invention.

The team

Built from inside the corridor it serves.

We're not building this for a slide deck. We're building it for the next time our families send a transfer — and for the millions of families paying the same tax we've paid for years.

I have watched my own family pay Western Union for years. I am building this because I should not need permission from a 170-year-old company to send my mother $200 in under five seconds. — FAIZAN ALI · MULTAN, PAKISTAN
