Base Vault Loses $6 Million in Aave Tokens After Whitelist Change
A Base vault holding Aave deposit tokens was drained of approximately $6 million following a change to its borrower whitelist. The withdrawn funds were converted to wstETH and routed toward Ethereum via bridge transfers.

The Drainage and Fund Flow
Approximately $6 million in Aave deposit tokens were withdrawn from a Base vault in six separate outflows tied to a whitelist modification affecting borrower permissions. According to blockchain analysis, the proceeds were systematically converted to wrapped staked ether (wstETH) before a portion entered bridge withdrawal paths toward Ethereum mainnet.
Whitelist Change as Trigger
The outflows occurred immediately after the whitelist governing vault borrower access was altered. The timing and pattern of the six withdrawals suggest the configuration change either enabled or triggered the drainage, though available reports do not confirm whether the change was authorized or malicious. The incident underscores operational risks inherent in vault governance structures where permission layers can reshape fund accessibility.
Why It Matters
For Traders
Monitor Aave lending on Base for further vault-related liquidity disruptions; the $6M drain may signal broader governance or security vulnerabilities in the protocol's Base deployment.
For Investors
Vault security and whitelist governance are material risks for multichain DeFi; this incident may prompt protocol reviews of permission-layer controls and incident-response procedures.
For Builders
Vault operators should audit whitelist mechanisms and implement circuit breakers or time-locks around permission changes to prevent rapid mass withdrawals after configuration shifts.
