Exploit on Coinbase’s Base Network Sees More Than $6 Million in Ether Stolen From Vault

An apparent exploit on Coinbase’s Base network has led to the theft of more than $6 million in ether from a vault, renewing questions about the security of high‑volume Layer‑2 infrastructure.

Coinbase’s Base network has been hit by an apparent exploit in which more than $6 million worth of ether was stolen from a vault, according to on‑chain monitoring.

The incident was flagged on social media by observers who noted large, unusual outflows from a vault smart contract on Base, the Ethereum Layer‑2 network incubated by Coinbase. The movements were described as “$6M+ in ETH” taken from the vault. At the time of reporting, there was no public, detailed technical explanation of the vulnerability behind the theft.

Base is designed to cut costs and increase speed by processing transactions off the main Ethereum chain and periodically settling them back. That setup concentrates funds in bridge contracts and vaults that hold user assets while they circulate on the Layer‑2. When one of those contracts is compromised, assets can be drained rapidly.

For users and developers building on Base, the episode is a reminder that smart‑contract and operational security risks remain central even on networks associated with major brands. Affected applications may pause activity while they check their own exposure and wait for clarity on what went wrong.

The exploit also lands as regulators and policymakers are still working out how to treat Layer‑2 networks in terms of investor protection and systemic risk. A theft of this size on a high‑profile platform gives them a concrete case to point to when weighing new rules or guidance.

Key signals in the next phase will be any technical post‑mortem from Base or Coinbase, changes pushed to contracts on the network, visible movements of the stolen ether to other addresses or services, and any steps taken to compensate users or pursue the attackers.
