SHORT FAMILY
$SFAM
Est. 1609 · Amsterdam → On-chain
SELL WHAT YOU DON'T OWNFamily motto since 1609
In 1609, Isaac le Maire borrowed shares of the Dutch East India Company in Amsterdam and sold them: the first recorded short sale. Four centuries later the family wears matching black-and-yellow tracksuits and runs the same business on-chain: borrow the asset, sell it, buy it back, return it.
$SFAM is the commemorative meme token of the Short Family, launched on BSC through Big Short. Contract address: TBD.

Ordered by how the trading mechanism was passed down, not by blood. Each generation steps one notch right and down. Dashed lines are side branches; † records the cause of death; d.s.p. means died without issue.
Gen. I · Founder
c.1558 – 1624 · Amsterdam
Borrowed shares of the Dutch East India Company (VOC) and sold them: the first recorded short sale. The VOC was then the largest listed company in the world, and the market had traded in one direction only. The Dutch banned short selling in 1610; the ban was reissued several times and short selling never stopped.
Gen. II
1794 – 1865 · New York
Built his fortune shorting in the 1830s and 1840s, the first Wall Street trader known for it. The family title The Great Bear of Wall Street starts with him.
Gen. III · Two of a generation · The Erie war
1797 – 1879 · Erie treasurer
"He who sells what isn't his'n, must buy it back or go to pris'n."
A cattle drover in his early years. The term watered stock is said to come from his habit of letting cattle drink before a sale.
1836 – 1892 · New York
Allied with Fisk and Drew against Vanderbilt's long position. The long-short battles of the era turned shorting from a tool of a few into standard Wall Street practice; members of Congress called short sellers “enemies of the nation”.
Gen. IV
1877 – 1940 · New York
Held net short positions through the crashes of 1907 and 1929; his 1929 profit is reported at about $100 million. After Jacob Little, the second family member called The Great Bear of Wall Street.
Family event · House rules adopted
After the 1929 crash the public demanded a ban on short selling. The SEC did not ban it and introduced the uptick rule instead: a short sale may execute only on an uptick. Shorting gained a legal framework and institutional money followed.
Family event · New branch
On April 26 the Chicago Board Options Exchange opened with call options on 16 stocks; puts were added in 1977. The Black-Scholes pricing model was published the same year. Trade directions expanded from 2 to 4.
Family event · Moved into crypto
Perpetual swap launched in May 2016, the first shorting tool in crypto.
Family event · Went mainstream
Perpetual swap launched in September 2019. BTC 30-day annualized volatility fell from above 150% in the 2017 bull market to 60–90% in the 2020–2021 bull market; the derivatives share of crypto volume rose from under 10% in 2017 to about 90% by March 2026.
Side branchD.S.P. 2025
fl. 2023 H2 – 2025 Q3
Exchanges listed altcoin perpetuals at a pace of roughly one per week, while altcoin volume and activity declined over the same period. The branch died without issue.

Code of Conduct
Six rules of conduct for family members.
Every short must be backed by real borrowed tokens sold on the spot market. Synthetic positions do not count as family assets.
Every short contains an immediate sell order and a buy order that must execute later. What is sold must be bought back and returned.
"...must buy it back or go to pris'n." D.DrewOnly the spot price counts. Spot margin has one market, so perp and spot cannot decouple.
Priced at the borrow rate, which lending supply and demand sets and the long-short ratio cannot distort. The family does not pay manipulated funding rates.
Shorting is subject to rules. The principle set by the 1938 uptick rule: regulate shorting, do not abolish it.
Longs and shorts trade against each other with real capital on the spot market; a price is credible only after shorts have tested it.
When criticism is not allowed, praise loses its meaning. When shorting is not allowed, going long loses its meaning too.
The Family Vault
Put $SFAM in the family vault and earn $SFAM every second in proportion to your share. Deposit, withdraw and claim anytime.
Deposit $SFAM into the vault contract; your share follows the amount deposited. Withdraw anytime.
Every $SFAM buy and sell pays a tax. Big Short sends the creator share in BNB to the buyback contract, which buys $SFAM with it and sends the tokens straight to the vault.
$SFAM bought back into the vault is released second by second, and your income grows every second in proportion to your share.
Claim accrued $SFAM at any time. Income already accrued stays yours after you withdraw.
Your share=your deposit÷vault total
Your income per second=vault release per second×Your share
Deposits open once the vault is bound to $SFAM. Income starts accruing after a 1-hour warm-up; $SFAM bought back before that is released afterwards.
Tokenomics
Supply and allocation follow the Big Short launch template and can be checked on-chain. Tax rate and contract address are final at launch.
How to Buy
