Deribit Moved 90% of Client Assets to Coinbase, Then Quietly Killed Daily Proof-of-Reserves

Deribit just removed the one transparency tool that let clients verify their own funds, days after quietly shifting 90% of client assets to Coinbase.

The derivatives giant killed its daily Merkle tree proof-of-reserves check on September 1, replacing it with VARA regulatory reports and audited materials that are far less accessible to ordinary users. If you had a position on Deribit and assumed you could verify your balance any morning you wanted, that ability is now gone.

What Actually Changed

Before September 1, Deribit ran a daily client-facing Merkle tree check. This is the gold standard of self-serve transparency in crypto: users could independently confirm their funds existed in the reserve pool without trusting anyone's word. It is the exact tool that would have exposed a fractional reserve situation before it became a crisis.

Now that check is gone. In its place, Deribit points to VARA compliance reports and third-party audited materials. These are not useless, but they are periodic, institutional, and not something a retail trader can run at 2am when markets are moving and anxiety is high.

The timing matters. The asset migration to Coinbase Custody and the removal of the daily check happened in close sequence, not months apart.

Why Coinbase Custody Complicates This

Moving 90% of client assets to Coinbase Custody is not inherently alarming. Coinbase is a regulated, publicly traded company with serious custodial infrastructure. But it does introduce a layer of institutional intermediary between clients and their funds, and it makes independent on-chain verification significantly harder for individual users.

When assets sit in identifiable on-chain wallets, anyone can watch them move. When they sit inside a custodian's omnibus structure, you need an audit to know anything. Deribit has now chosen audits over transparency, and that is a deliberate policy decision worth scrutinizing.

What the Removal of Merkle Checks Actually Signals

Proof-of-reserves became a non-negotiable expectation after FTX collapsed in November 2022. Exchanges that dropped or weakened those checks in the months following faced immediate backlash. Deribit is making this change in a bull market cycle, when scrutiny is lower and user appetite for risk is higher. That is the optimal moment to make an unpopular policy change with minimal noise.

What Traders Should Watch

If you hold funds on Deribit, the practical implication is simple: your ability to self-verify has been removed. You are now dependent on scheduled audits and regulatory filings to confirm solvency.

Watch whether other major derivatives platforms follow this pattern. If proof-of-reserves quietly becomes an industry relic during this bull cycle, the next liquidity crisis will catch far more traders off guard than FTX did.

Request the audit materials directly. Do not wait for the next report cycle to ask questions.
