01 — The Document

Page 11 of a
1000-year mandate.

On February 25, 2026 the Ethereum Foundation sent every employee its Mandate, v1.4. Down at the bottom of page 11 sat a license. Read it slowly. They did.

Case 1:26-cv-05818 · Document 1EXHIBIT 4 · pg 11

SOURCE LICENSE

By inclusion of this license, the author, maintainer, editor or (re)distributor (the "Actor") of this software SHALL uphold the following pledges:

  1. 1.

    To always make freely available and publicly accessible a full and accurate copy of the source code and associated documents of this software, including all modifications hereto by the Actor.

  2. 2.

    To take his or her own life with a sword upon failure to uphold any of the pledges in this license, or upon modification or removal of any part of this license.

May we ritualistically fall on our own swords if we fail to uphold our solemn promise to Ethereum and the Infinite Garden.

Nobody has sealed it on this device yet. Be the first Actor.

02 — The Scroll of Events

How a footnote
became a coin.

01

The Mandate drops

Version 1.4 goes to all staff. It calls Ethereum "a liberatory technology." Page 11 carries a heading: SOURCE SEPPUKU LICENSE.

令
02

"Has got to go."

Staff object the same week. One writes: "the seppuku license has got to go. if it's a litmus test for CROPS commitment, i'm failing it."

03

79 votes

A proposal to remove the license. Seventy-nine employees vote yes. The garden, apparently, has a quorum problem.

79
04

"Significant changes"

The board says the Mandate is "continuing to be worked on with significant changes especially to the areas where people have expressed the most concern or confusion."

変
05

The glow-up

Final version: same words, not one changed. Now Comic Sans, tilted, glitched, guarded by three cartoon cats and a winking anime figure. "Seppuku" vanishes from the searchable text.

06

Calldata, forever

The full document is inscribed on the Ethereum blockchain as transaction calldata. You cannot redact a block.

Exhibit 4

The license lands in federal court as an exhibit to an employment complaint filed in the District of Colorado, No. 1:26-cv-05818.

08

The cats keep the oath

The girl winked. The cats stayed. The internet did the rest. $SEPPUKU: the license you can hold.

03 — The Vow

May we ritualistically fall on our own swords if we fail to uphold our solemn promise to Ethereum and the Infinite Garden.

From the license, Exhibit 3 at 11. We take it the way management told staff to: "not meant to be taken literally." Honor-bound. Metaphorically.

04 — The Shrine Archive

Scrolls from the
night shrine.

Cats with ETH on the roof, a samurai on the skyline, a judge in a wig. Click any scroll to open it. Throw the cats around while you're here.

05 — The Ritual

Four steps.
Zero swords.

壱

Step 01

Get a wallet

Install MetaMask, Rabby or any Ethereum wallet. Write the seed phrase on paper. Never type it into a website. We never DM first.

弐

Step 02

Load ETH

Buy ETH on an exchange and send it to your wallet on Ethereum mainnet. Keep a little extra for gas.

参

Step 03

Open Uniswap

Tap Buy on this page. It opens Uniswap with the official $SEPPUKU contract already filled in. Only trust the address shown here.

肆

Step 04

Swap & seal

Swap ETH for $SEPPUKU, confirm in your wallet, and welcome to the Infinite Garden. Honor-bound, metaphorically.

06 — The Ledger

Chart

Chart unlocks at launch

The DexScreener chart appears here the moment the contract goes live. Until then, the only thing trading is glances.
