jaredfromsubway.eth

A pseudonymous MEV bot operator who became notorious for executing Sandwich Attacks on Ethereum, extracting millions of dollars from retail traders during memecoin frenzies. The name references Jared Fogle, the former Subway spokesperson convicted of sex crimes - a dark joke about "sandwiching" victims.

Summary

Launched February 21, 2023; became dominant MEV actor by April 2023
At peak activity, present in over 60% of Ethereum blocks
Extracted an estimated $22M+ in MEV revenue (net profit disputed, likely $4-6M)
Spent over $34M in gas fees to execute attacks
Targeted memecoin traders during PEPE, WOJAK, and ENA frenzies
Evolved to "Jared 2.0" in August 2024 with more sophisticated multi-layer attacks
Operator identity remains unknown

The Mechanics

How Sandwich Attacks Work

A sandwich attack exploits the transparent nature of Ethereum's Mempool. When a trader submits a swap on a DEX, the pending transaction is visible to anyone monitoring the network. The attacker:

Detects a large pending swap (the "victim" transaction)
Front-runs with a buy order at higher gas, pushing the price up
Lets the victim's transaction execute at the now-worse price
Back-runs with a sell order, capturing the price difference

The victim receives fewer tokens than expected. The attacker pockets the difference minus gas costs.

    Victim->>Mempool: Submit swap (visible)
    Jared->>Mempool: Detect victim transaction
    Jared->>DEX: Front-run buy (high gas)
    Note over DEX: Price pushed up
    Victim->>DEX: Swap executes at worse price
    Jared->>DEX: Back-run sell
    Note over Jared: Profit captured

Figure 1: Standard sandwich attack flow. Jared's bot monitors the mempool, front-runs the victim with a high-gas transaction, then back-runs to extract value.

Why It Works

Victims set Slippage tolerance (often 1-5%) to ensure transactions complete
Attackers extract up to the maximum slippage the victim allows
High volatility tokens (memecoins) attract high slippage settings
AMM pricing is deterministic - attackers can calculate exact profits

Jared 2.0	`0x1f2f10d1c40777ae1da742455c65828ff36df387`	Active
Creator EOA	`0x4d521577f820525964c392352bb220482f1aa63b`	Same for both versions
ENS	`jaredfromsubway.eth`	Resolves to `0xae2Fc483527b8ef99eb5d9b44875f005ba1FaE13`

Both bot contracts were created by the same EOA, confirming they are operated by the same entity.

Attack Evolution

Jared 1.0 (2023-2024)

The original bot executed straightforward sandwich attacks:

Front-run → Victim → Back-run
Simple swap-based manipulation
High gas bidding to secure block position
No builder tips detected (relied on gas priority)

Jared 2.0 (August 2024+)

The upgraded bot introduced more sophisticated "recipes":

5-Layer Sandwich:

Add liquidity (front)
Victim transaction
Swap (centerpiece manipulation)
Victim transaction
Remove liquidity (back)

7-Layer Sandwich:

Multiple victims sandwiched simultaneously with liquidity add/remove operations interspersed. This creates arbitrage opportunities across multiple transactions in a single block.

Key Improvements:

Uses liquidity provision as attack vectors (not just swaps)
Harder to detect and analyze profitability
Targets multiple victims per block
Possible CEX-DEX arbitrage integration

Notable Campaigns

PEPE Memecoin (April 2023)

The PEPE memecoin launch in April 2023 created ideal hunting conditions:

Extreme volatility (price discovery phase)
High trading volume ($100M+ daily on Uniswap)
Retail traders using high slippage (5-10%) to ensure fills
FOMO-driven buying with no MEV protection

During the peak week (April 17-24):

$2.7M profit extracted
7% of all Ethereum gas fees paid by jaredfromsubway
Over 11,000 trades executed daily
Other targets: WOJAK, CHAD, APED, MONG, LADYS, BOB

Ethena ENA Launch (April 2024)

The ENA token launch on April 2, 2024 saw jaredfromsubway return to form:

$14.8M in ENA trading volume engaged by the bot
~$300K profit on April 3 alone (best day since September 2023)
Token nearly doubled in value within hours, creating volatility
Estimated 5-10% of PEPE-era profits from this single campaign

Builder Relationships

Jared's transactions route through block builders who receive tips:

BUILDER	REWARDS RECEIVED	TRANSACTIONS
Beaverbuild	686 ETH (~$1.76M)	~30,000
Titan	129 ETH (~$331K)	~16,000

The bot shows no clear preference among top builders - transactions are distributed based on who builds winning blocks. 98% of transactions went through public channels; only 155 used private conduits.

Protection Mechanisms

Several tools exist to protect against sandwich attacks like those executed by jaredfromsubway:

Flashbots Protect

RPC endpoint: rpc.flashbots.net/fast
Sends transactions to private mempool (invisible to searchers)
Failed transactions don't cost gas
MEV rebates if your transaction creates extractable value

MEV Blocker

RPC endpoint: mevblocker.io
90% of backrun profits returned to users
Multiple modes: /fast, /fullprivacy, /noreverts

User Behavior

Set low slippage tolerance (0.5-1% when possible)
Accept that low slippage may cause failed transactions on volatile tokens
Use DEXs with built-in MEV protection (CoW Swap, 1inch Fusion)
Avoid large swaps during high-volatility periods

Identity

The operator behind jaredfromsubway.eth remains anonymous. Despite extensive on-chain analysis:

No public identification or doxxing has occurred
The pseudonym is deliberately provocative (referencing a convicted criminal)
On-chain patterns confirm both bot versions share the same operator
No known social media presence or public communications

The choice of name suggests either dark humor about "sandwiching" victims or deliberate provocation of the crypto community.

Lessons

For Traders:

The mempool is public. Your pending transactions are visible.
High slippage tolerance is an invitation to be sandwiched.
MEV protection tools exist. Use them.
"Making it" on a memecoin launch has a hidden tax.

For the Ecosystem:

MEV extraction is a rational economic activity, not a bug.
$22M+ extracted by one operator demonstrates the scale of the problem.
Private mempools and MEV protection shift the battlefield, but don't eliminate MEV.
Protocol-level solutions (Uniswap V4 hooks, intent-based trading) are evolving.
