At a glance
What changes about a transfer
Transaction cost measured in fractions of a cent rather than a percentage of the amount sent.
Money moves between countries in seconds, against a correspondent banking baseline of days.
A chain designed for payments and asset issuance rather than general computation.
The cost stops scaling with the amount, which changes who remittance works for.
The brief
The people who send least pay the most
Remittance pricing is percentage-based, so the smaller the transfer the worse the deal. A migrant worker sending a few hundred currency units home loses a meaningful slice of it to fees, and waits days for the rest to arrive.
That is a structural feature of correspondent banking rather than a pricing choice anyone made. Each intermediary in the chain takes a cut and adds a delay, and there are several.
When the fee is a percentage, the smallest transfers subsidise the system.
The build
Why Stellar rather than a general chain
Stellar exists specifically for moving value and issuing assets, and its economics reflect that: transaction costs low enough that a remittance product can be priced as a flat fraction of a cent instead of a percentage.
On a general-purpose chain the same product would carry variable gas costs that reintroduce exactly the unpredictability remittance users are trying to escape. The chain choice is the product decision here, not an implementation detail.
Wow Labz covered UI design, frontend and backend development, and testing.
What it does
Three properties that matter
Cost measured in fractions of a cent
Fees stop being proportional to the amount, which disproportionately helps the smallest and most frequent transfers.
Settlement in seconds
Money arrives in seconds rather than clearing through a chain of correspondent banks over days.
Built on Stellar
A distributed ledger purpose-built for payments and asset issuance, rather than a general-purpose chain adapted to it.

Questions
Snapex, answered
What is Snapex?
A cross border remittance product built on the Stellar blockchain, letting people send money between countries in seconds at a cost measured in fractions of a cent.
How much does a transfer cost?
A fraction of a cent, rather than a percentage of the amount being sent.
Why build on Stellar?
Because Stellar is designed for payments and asset issuance specifically. Its transaction economics are what allow flat, negligible fees instead of variable costs that would reintroduce unpredictability.
What did Wow Labz build?
UI design, frontend development, backend development and testing.
