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 sixteenth 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 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.
