The tea auction closed three days ago. Wanjiru's buyer in Guangzhou paid on time. She can see the wire confirmation he emailed. What she can't see is the money. It's somewhere between four correspondent banks, shedding 4% as it travels, while her next harvest sits unfunded.
Now the buyer pays into a Transacty account, the money crosses on the USDC backbone overnight, and Wanjiru wakes up to shillings: whole, visible, already paying for the next lorry. She sees the FX rate before the money moves, not after it's gone.
