MEXC Ventures flags custody risks in DataVault AI and Keystone cases
- —DataVault AI has not withdrawn BTC from Biconomy since June 2026 after a $150 million deal with Cyrex
- —Of 1,309.04 BTC received, 491.431 BTC were sold back to Cyrex for about $40.5 million
- —Keystone will scrap 18,835 unshipped devices and disclosed a leak of 25,964 records
- —MEXC reported proof-of-reserves ratios of 294% for BTC, 122% for USDT, 115% for USDC and 111% for ETH
Why it matters: The report underscores that exchange balances and hardware wallets alone do not prove control of assets, making verifiable reserves and access controls essential.
