TL;DR - OFAC added four Tron-based crypto addresses tied to Iran's central bank to the SDN list on July 16, 2026, pushing Plastron's tracked sanctions dataset to 938 addresses across chains.
On July 16, 2026, Plastron's daily automated diff against the U.S. Treasury OFAC SDN list detected four new digital-currency addresses. All four were added under the designation for BANK MARKAZI JOMHOURI ISLAMI IRAN, the central bank of Iran, and carry the IRAN, SDGT, IRGC, and IFSR sanctions programs.
What happened
The four newly listed addresses are:

All four are Tron (TRX) format addresses rather than Ethereum-format addresses. They surfaced through Plastron's daily comparison of the current OFAC recent actions list against our committed screening dataset. That daily diff is how new SDN crypto designations get picked up the same day Treasury posts them, rather than weeks later when a wallet has already interacted with the address. Plastron's screening pipeline runs this diff every day against the full OFAC SDN list rather than checking on a periodic schedule, so a newly designated address can show up in scan results within about a day of Treasury's action.
Who is affected
Anyone who has sent funds to, received funds from, or otherwise transacted with these four addresses is now dealing with a sanctioned counterparty under U.S. law. The designation attaches to BANK MARKAZI JOMHOURI ISLAMI IRAN as an entity, so any other address or account tied to that entity carries comparable exposure, not only the four listed here. Exchanges, payment processors, and individual wallet holders with any historical exposure to Iranian central bank infrastructure should treat this as relevant. Sanctions screening obligations apply regardless of transaction size, so even a small test transfer to a listed address creates the same compliance issue as a large one.
