The US Treasury’s Office of Foreign Assets Control (OFAC) sanctioned crypto exchanges Shelbit and Aban Tether on August 7, accusing them of moving funds for Iran’s Islamic Revolutionary Guard Corps. TRM Labs data show the unlicensed, Dubai-registered exchange Shelbit processed more than $6.3 billion in flows between May 2024 and March 2026, which OFAC described as a settlement layer for Iran’s illicit economy. The action is part of the Treasury’s “Economic Fury” campaign and marks the latest step since January targeting Iran-linked crypto platforms.

The WBTC transition is expected to help shift nearly $15 billion in digital assets from LayerZero’s framework to Chainlink’s protocol, highlighting how bridge risk is pushing issuers toward alternative interoperability standards.

Ether.fi said it has restructured its token design by fully separating restaking from its main token, weETH.

The restaking exposure is moved to a newly introduced token, weETHs. Ether.fi said the move is intended to give investors clearer product choices based on different risk preferences, positioning weETH as a simpler yield instrument.
