No. Welcome to the petrobitcoin economy.

Edit: Piecing together from other comments, it sounds like these tolls are denominated in USD ($1 per barrel), but as an implementation detail, they're charging in BTC as the instrument of choice, not a stablecoin.

They phrase the tolls in USD "so the price is stable", and since the whole transaction is quick, BTC entails "just a small carry risk while holding". They sidestep the stablecoin technology, which is "risky for Iran because the top stablecoins could be freezed. They are centralized."

The latter comment was downvoted, possibly for paranoia, but Iran can't afford not to be paranoid. The major stablecoins at least claim to be custodied in Western institutions in a quasi-compliant-ish manner. If the USG started strong-arming Cantor, and so forth, who knows where that would end. Iran would much rather live with a tiny taste of BTC price volatility.

So my read of this is:

- Iran is threading the needle, working within the limited options they have in a US-dominated world economy.

- The death of the petrodollar is slightly exaggerated here, although it's a small symbolic step, and obviously the broader war is going to have implications for US hegemony.
