Deribit ends daily proof of reserves amid Coinbase custody shift

Deribit will remove its public Proof of Reserves page on Sept. 1, ending a daily check customers could use to verify balance inclusion and compare aggregate liabilities with published wallet holdings. Regulator-required reserve, reconciliation and audit controls will remain, but they do not provide the same daily public visibility.

The exchange said the change reflects a wallet infrastructure overhaul during its integration with Coinbase. Deribit said roughly 90% of client assets have moved into Coinbase custody arrangements since Coinbase acquired the derivatives platform in August 2025. Its disclosures name Coinbase at the brand level but do not identify the specific Coinbase legal entity holding the migrated assets.

Deribit’s existing system uses a privacy-preserving binary Merkle tree and a daily snapshot. Each client can use a unique proof identifier to find the hashed entries representing their balances, while anyone can sum the file’s liabilities and compare the total with wallet balances published by Deribit.

The public snapshot was already narrower than Deribit’s full custody footprint. Its methodology says assets held with third-party custodians are excluded because they are outside Deribit’s direct control, naming Copper ClearLoop as an example. It does not say whether every Coinbase-held asset was already excluded.

After Sept. 1, Deribit has not promised a replacement public dashboard or continued client-level Merkle verification. It said clients and counterparties may request audited financial statements and other due-diligence material, a less frequent and less directly verifiable form of evidence.
