FLETCH
STABILIZATION IN PROGRESS · VANE 3/3 · 120.000°
BY ARROW FINANCE · ROBINHOOD CHAIN

The arrow flies
because of the fletching.

Arrow Finance built the asset. Somebody has to keep it pointed the right way. FLETCH is the stabilization layer — three vanes, 120 degrees, zero questions answered.

FIG. 01 — REAR VIEW OF CONVICTION
01 — PROBLEM

An unstabilized arrow
is just an expensive stick.

Everyone celebrates the arrowhead. Nobody thanks the feathers at the back doing all the work. Remove the fletching and observe the results:

0
TUMBLES / SEC (UNFLETCHED)
Technically impressive. Strategically catastrophic.
0%
TARGETS MISSED
The remaining 6% were hit by accident. We checked.
100%
DIGNITY LOST
An arrow spinning sideways into a bush. Every time.

VANES REQUIRED
Not two. Not four. Three. This is the entire whitepaper.
02 — LABORATORY

The wind tunnel.

Our full technical thesis, demonstrated live. Toggle the fletching. Watch what happens to an arrow that thinks it can fly alone.

Aerodynamic papers.

Peer-reviewed by three feathers and a shaft. All findings final. Some findings redacted — for aerodynamic reasons.

FLETCH-001Vane Geometry Specificationv1.2 · STABLE

Three vanes, mounted at 120.000° intervals. Helical offset: 1.5° — enough spin to stay honest, not enough to get dizzy.

Section 4.2: attempts to use two vanes result in what our engineers describe as "a coin flip with extra steps." Attempts to use four vanes result in drag, which is what we call things that hold arrows back. See also: sellers.

FLETCH-002On the Aerodynamics of ConvictionPREPRINT

An arrow in flight experiences three forces: gravity, drag, and doubt. The fletching cancels the third one. The first two are the holder's problem.

Findings: conviction, like airflow, must remain laminar. Turbulent conviction is known in the literature as "panic selling."

AERO-701Drag Memorandum ██████████REDACTED

The contents of this memorandum are ██████████████████ pending review by ████████. What we can disclose: drag coefficient 0.0031, measured at ██████ altitude, over Sherwood.

Conclusion (unredacted): the feathers were right.

FLETCH-005Relationship to the ArrowCANON

Arrow Finance is the arrow: the asset, the CDP layer, the thing everyone watches. FLETCH is the part of the arrow nobody watches — which is precisely why it works. We are not competing with the arrow. We are attached to it. Permanently. By design.

Q: "Is this official?" A: the fletching does not require permission from the arrowhead.

04 — UPSTREAM

We read the mothership's flight code.

Robinhood's actual open-source repositories — the code that kept millions of arrows scrolling, streaming, and charting. FLETCH engineering studies upstream. The annotations are ours.
