Every control that failed in Orlen's $424m oil trade sat off-chain

Take the conversion leg by itself. Hannon exchanged $245m at multiple Dubai companies, having added $15m of its own to the deal, and came out holding 165m USDT ^[5][9]. That is $80m short, about a third of what went in, before anyone had flown to Venezuela ^[1]. One leg cleared at par: $80m became 80m USDT ^[6]. A $135m exchange produced 85m USDT, leaving $50m unaccounted for ^[7]. A $30m exchange vanished and much later gave back 21m USDT, roughly seventy cents on the dollar ^[8][19][3].

The biggest loss was a hand-to-hand transfer. Hannon's representative handed 60m USDT on one USB wallet to a purported representative of a local energy firm, Synergy ^[15]. What came back, after weeks, was a photograph of a purported PDVSA export schedule listing all three Polish tankers for 1.9m barrels each, with no predicted date ^[16]. Tse's team then handed the same representative another 50m USDT on a second USB wallet, and he vanished ^[17]. That is 110m USDT to one counterparty whose employer nobody had confirmed ^[2]. They had armored cars and bodyguards to protect the sticks ^[13].

Tom's Hardware, summarising a Financial Times account, argues the ledger was not the failure point: for most currencies the on-chain record gives more visibility into transactions, not less, and no official record linked the wallets to persons or entities ^[24][3]. Identity verification is mandatory at reputable exchanges ^[25], and it stops at the exchange boundary. By that account almost none of the entities Hannon traded with had recognizable proof that their wallets belonged to them ^[26]. The crude sellers then vanished; their disappearance closed off nearly every route for investigation ^[27], and they had earlier told Tse to keep no records of their transactions, citing a government investigation into their collective's dealings ^[28]. In Dubai, pending court cases over the dollar-to-USDT exchanges turn on the same gap between a wallet and its owner ^[29].

A counterparty who asks you to keep no records has already told you enough to walk away. I would have stopped there.

For a team wiring a stablecoin leg into a payment path, the controls this account puts in play are three: an ownership attestation binding a receiving wallet to a legal entity before value moves, split custody so no single traveller can transfer the whole balance, and delivery evidence a court would accept instead of a photograph.

The physical side paid for the delay. Three chartered Polish tankers sat anchored off Venezuela running up demurrage and port fees, held far longer than the charters assumed ^[10], and shipping came to $72m, more than the expected profit on the trade ^[23]. The total lost and spent is about 71 percent of the $600m Orlen had in hand at the start ^[4]. One ship loaded 500,000 barrels of fuel oil, half the contracted volume, after Tse paid the Venezuelan firm Consulting Services 11m USDT; a second 11m payment brought no delivery and no further contact ^[21][20][22]. The figures come from the Polish government's investigation, as reported by Tom's Hardware from the FT's reconstruction ^[23][3].
