Custodian Attestations of Assets Backing USDe: September

September 30th, 2025

In an effort to improve the transparency of the Ethena protocol’s backing assets beyond our current collateral and exchange breakdown provided on the dashboards, we are excited to share our seventeenth attestation report from all integrated custodians, verifying the assets backing USDe reside off-exchange within institutional custodial solutions.

Attestation reports are released on a monthly basis to provide regular updates as to the amount and location of the assets backing the protocol. The monthly attestation reports will be shared in the Ethena governance forum.

The aim of these reports is to prove an independent third party assessment that all assets backing USDe sit off-exchange within institutional grade custodial solutions.

As of 23:59 UTC September 17th 2025, USDe supply was 13.659bn as per the Etherscan link below:
