Subject: A $3 move on one exchange paid out on another

THE DAILY LEDGER

11 October 2026
A borrowed price gets pushed on Papertrade, ether funds have their worst week since January, and Coldcard's account carries a phishing link.

Reporting window: 10 October 2026, 20:00 UTC to 11 October, 23:30 UTC (01:30 on 12 October, Europe/Stockholm). Data cutoff: 23:30 UTC on 11 October, later than our usual 06:00 UTC because the first detailed reports of the Papertrade trades appeared on Sunday evening UTC. Trade times are US Eastern, as reported. Prices are CoinGecko 00:00 UTC snapshots; ETF figures cover completed sessions to Friday 9 October. This issue was published retrospectively on 16 October 2026 to fill a gap in the archive; it uses only information available at the cutoff.

What is oracle manipulation in perpetual futures? It is moving the price a derivatives venue reads, rather than the market it trades, so positions settle at a number the manipulator chose. On Saturday a trader showed how cheaply it can work on Papertrade, a new 1,000x leverage exchange that takes its prices straight from Hyperliquid.

1. The Day in Numbers

• Bitcoin: $82,918 at 00:00 UTC, up 0.4 percent against the previous day's 00:00 UTC snapshot. CoinGecko daily series.
• Ether: $2,504.31, up 0.7 percent on the same basis.
• Fear and Greed: 61, Greed, down 3 points from 64. Alternative.me daily reading.
• Bitcoin market value: $1.666 trillion at the same snapshot.

2. What is oracle manipulation in perpetual futures?

A perpetual future is a contract with no expiry date that tracks an asset's price. Profit, loss and liquidations are all calculated from a reference price, and the oracle is whatever supplies it. If that reference can be moved for less than the positions it settles are worth, the venue is selling its price.

Papertrade went live at 10 a.m. ET on Saturday on HyperEVM, the smart contract layer of Hyperliquid. The Block reports that it prices every trade at the midpoint of Hyperliquid's best bid and offer and takes the other side through a shared USDC pool. DeFiPrime, reading Papertrade's documentation, says the feed rejects only a zero or crossed quote. It has no maximum-deviation check, time-weighted price or circuit breaker, and the documentation names the risk: move Hyperliquid's quote briefly, then trade against the distorted midpoint.

Between 6:01 and 6:02 p.m. ET one wallet bought about 6,060 ETH on Hyperliquid as the price rose roughly $3, or 0.12 percent. At 6:03 it sold about 5,210 ETH and the price fell about $3.50. Papertrade's records show $1.28 million of profit on $3.18 billion of volume, and the wallet withdrew about $2.48 million against $1.2 million deposited. Later, 30 ETH shorts at 660x leverage were liquidated at 10:31 p.m. for a $450,000 loss. The pool fell from about $5 million to about $2.4 million before recovering.

Leverage makes a tiny push pay. At 1,000x, a 0.12 percent move is worth 120 percent of the margin posted. Pushing the price costs something in spreads; a venue settling far larger positions at the moved midpoint pays the difference.

On Sunday Papertrade blamed loose launch caps on open interest, the total size of open positions, and said it was tightening them. It said the trader returned most of the gains; The Block could not verify that. Lower caps shrink the payoff but do not check the price. Sturdier venues use references that are expensive to move, such as medians across several markets or time-weighted averages, and limit how far a price may jump between reads.

3. Today's Headlines

Ether funds post their worst week since January

US spot ether ETFs lost $542.1 million in the week to Friday, the most since January, and have shed $697.2 million over nine straight outflow days, according to SoSoValue data. BlackRock's ETHA accounted for about $477 million. Bitcoin ETFs lost about $680 million despite a $21.1 million inflow on Friday. An outflow means more shares were redeemed than created; it is not a direct count of coins sold on exchanges.

Coldcard's own X account posts a phishing link

Coldcard said an unauthorised phishing link appeared on its official X account on Sunday. The post was deleted; Coldcard said coldcard.com is its only official website and it is reviewing account access with X.

4. Security Note

Search results and verified accounts are not proof of authenticity. Researchers flagged a fake Ledger website and app near the top of Google results that asked visitors for their 24-word recovery phrase; a claimed figure of one million visits is unverified. The rule: reach wallet software through an address you type or a bookmark you made, and never enter a recovery phrase into any website or app.
