Iran opened fire, hitting a tanker that was paying Bitcoin tolls to scammers.

Deep Tide Guide: Less than two weeks after Iran announced collecting tolls via Bitcoin through the Strait of Hormuz, scammers impersonated Iranian officials to send fake messages to stranded oil tankers demanding BTC and USDT.

At least one oil tanker that paid the fake toll was fired upon by the Iranian Revolutionary Guard while attempting to pass. On-chain analysis firms TRM Labs and Chainalysis both stated that no on-chain evidence of large-scale cryptocurrency toll collection has been found to date.

Iran announced it would collect tolls using Bitcoin, and scammers turned this narrative into a weapon within two weeks.

According to Reuters on April 21, Greek maritime risk management company MARISKS issued a warning: unidentified individuals impersonating Iranian authorities sent false messages to ships stranded on the western side of the Strait of Hormuz, demanding payment in BTC or USDT for “toll fees” in exchange for safe passage. MARISKS believes that at least one vessel that was fired upon by Iranian Revolutionary Guard gunboats when the strait was briefly opened on April 18 was a victim of this scam.

The absurdity of the incident lies in the entire causal chain: a sovereign nation announces collecting Bitcoin tolls, scammers copy this narrative to deceive, shipowners believe it and pay, and then the real Iranian military opens fire.

From “national-level settlement tool” to scammer attack surface

The story begins in early April.

The Iranian Parliament passed the “Hormuz Strait Management Plan” from March 30 to 31, officially codifying the toll system that the Islamic Revolutionary Guard Corps has been implementing since mid-March. According to the Financial Times, Hamid Hosseini, spokesperson for the Iranian Oil, Gas, and Petrochemical Exporters’ Union, confirmed that laden oil tankers are required to pay a fee of $1 per barrel, payable in Bitcoin, USDT, or RMB. A supertanker loaded with 2 million barrels of crude oil could pay up to $2 million in tolls at once.

Once the news broke, Bitcoin’s price surged 5%, briefly surpassing $72.7k. The crypto community quickly interpreted this as a milestone validation of Bitcoin as a “neutral settlement layer in international trade.” Institutions like Bitwise even linked it to predictions of Bitcoin reaching $1 million.

But skeptics were also numerous.

Sam Lyman of the Bitcoin Policy Institute pointed out in a report on April 15 that collecting Bitcoin tolls on a large scale with current technology is “almost impossible.” Ari Redbord, TRM Labs’ global policy head, told Forbes that on-chain data does not show large-scale toll payments occurring. Chainalysis’ analysis report indicated that on-chain activity related to Iranian entities mainly relies on USDT on Tron, not Bitcoin.

Scammers don’t care about these technical debates. They only need a credible narrative, and the Iranian government has already written the script for them.

Paid with fake money, shot with real guns

According to Reuters and DL News, the wording of scam messages closely mimics official language. Scammers ask shipowners to submit vessel documents, claiming that “Iranian security agencies” will evaluate them. After approval, payment in BTC or USDT is required, and then the ship can pass through the strait safely at the “scheduled time.”

Currently, about 400 ships and 20k crew members are stranded in the Persian Gulf. The US blockade of Iranian ports, combined with Iran’s repeated opening and closing of the strait, creates a tense environment. Shipowners’ anxiety is understandable, and scammers have exploited this precisely.

On April 18, when Iran briefly reopened the strait, some ships attempted to pass. According to the UK Maritime Trade Operations (UKMTO), two Iranian Revolutionary Guard gunboats fired upon an oil tanker trying to exit the strait, forcing it to turn back. MARISKS believes that this oil tanker had previously paid the scammers in cryptocurrency “tolls,” thinking it had obtained permission to pass.

Paid but the money didn’t reach Iran. The ship was still fired upon.

Paying scammers may also violate sanctions laws

Even if shipowners realize they’ve been scammed, legal risks remain.

Xue Yin Peh, head of investigation strategy at Chainalysis, told Decrypt that regardless of whether the recipient is truly Iranian authorities, paying a sanctioned regime could violate OFAC, EU, and UK sanctions laws. In other words, even if you think you’re paying Iran, and the money ends up with scammers, authorities can still pursue you based on your “intent.”

Isabella Chase, policy head for EMEA at TRM Labs, also warned that any wallet addresses associated with such requests should be considered “high risk,” and cryptocurrency payments do not offer any “safe harbor” in sanctions compliance.

This creates an almost impossible dilemma for shipowners: paying Iran is a sanctions violation, paying scammers might also be a violation, and not paying means drifting in the Persian Gulf.

“Bitcoin is irreversible” turns from an advantage into a flaw

The most important reflection for the crypto industry is how Bitcoin’s core feature performs in this scenario.

Benzinga highlighted a key issue: once a cryptocurrency payment is sent, it cannot be reversed. Unlike traditional bank transfers, which can be frozen or recovered, once Bitcoin or USDT is transferred, the funds are lost. This feature, in normal business contexts, is called “trustless settlement,” but in war + scam scenarios, it becomes “losses that cannot be recovered.”

This might be the most absurd crypto story of 2026… Iran’s plan to collect tolls via Bitcoin may never have truly materialized, but scammers have already profited from this story, and a tanker was shot.
