A travel rewards platform.
DerLeng Free is a travel rewards platform. You search hotels and flights worldwide, book through our partner sites, and earn cashback on every booking.
The cashback is paid in LENG or USDC and holds a fixed value. It is convertible and withdrawable, it does not expire, and — unlike hotel loyalty points — it is never locked to a single brand.
Derleng Free Travel LLC is registered in Tbilisi, Georgia. DerLeng Free was born in Cambodia, and the service is worldwide.
ដើរលេង — Go play.
ដើរលេង(Der Leng) is Khmer for 'go play' — the spirit of moving freely through the world without burden. Free Travel is not a discount. It is a destination. The promise is simple: act well enough, and the world pays for your next journey.
The King butterfly.

The butterfly across cultures is transformation — a creature that earns its wings through complete metamorphosis. It gives everything to become something freer.
The King edition is gold — the universal color of merit, of value, of light breaking through darkness.
The two wings overlap: one gold (contribution), one navy (the ocean, the night, the unknown journey ahead). They are never separate — because earning and giving are never separate.
The drops below the wings are tears and rain — the price of transformation, and the source of all growth.
Where merit meets money.
Across every culture and every tradition, meritorious acts accumulate. They are the invisible ledger of a good life — called BOUN in Khmer, karma in Sanskrit, sawab in Arabic, mitzvah in Hebrew, virtue in Latin. The word changes. The value never does.
Nobody records these acts. Nobody rewards them. They are simply done — and forgotten by the world, if not by conscience.
DerLeng Free says: we record them. We reward them. We give them financial weight.
BOUN — our reward token — carries this meaning deliberately. The good act done without expectation of return. DerLeng Free takes what was invisible and makes it visible. What was universal and gives it financial form.
“Every culture has a word for merit.
We built the ledger for all of them.”
Every gain has a paired loss.
This is not pessimism — it is physics. It is wisdom. It is ecology.
When you take from the ocean, the ocean loses. When you clean the ocean, the ocean gains — and so do you.
DerLeng Free is built on this symmetry. The economy only works if the actions are real. The rewards only exist because the contributions exist. Nothing is created from nothing.
This is the Living System Principle. It is locked in Constitution v1. It cannot be changed by any admin, founder, or government.
Finance + Philosophy + Spirit + Travel + Freedom.
BOUN is USDC-backed. LENG converts to real money. This is not charity — it is a new economy.
Article 0 governs everything. Every reward has a paired contribution. The system is self-balancing.
Every culture has a word for merit. Every act you verify is recorded, permanent, and given real value.
The platform was born from movement. EV transport, heritage trails, ocean depths — travel is the act.
Free Travel is the destination. When contribution funds your next journey, the loop is complete.
A world where doing good funds freedom.
The long arc of DerLeng Free is a world where doing good funds the freedom to do more good.
- Where a fisherman who protects his reef earns enough USDC to send his child to school.
- Where a traveler who chooses zero-emission transport earns enough to fund the next leg of their journey.
- Where a community that plants mangroves earns more than a corporation that destroys them.
This is the free world — not free as in cheap, but free as in unencumbered. Free to move. Free to act. Free to contribute. The planet as the economy.
You are not a user.You are a guardian.
Every act you verify becomes part of the permanent record of what humanity chose to do when the planet needed it most.
Go play. But play for keeps.
