Solana weighs removing feature exploited in $270m DeFi hack
Solana developers are weighing a proposal to remove a feature exploited in a $270 million DeFi hack, citing a 2022 incident that halted the mainnet for about 4.5 hours.

Solana is considering removing a network feature that was exploited in a DeFi hack worth $270 million. A new proposal argues the feature poses a risk to the blockchain's stability and should be cut.
To support its case, the proposal points to a 2022 incident that halted the Solana mainnet for about 4.5 hours. Together, the two episodes form the core of the argument: a capability that has already been tied to a major outage and a large-scale exploit is, in the proposal's view, a liability.
Why it matters
Solana is one of the most active networks for decentralized finance, and reliability is central to its pitch to developers and users. A network halt of several hours interrupts trading, lending and other on-chain activity, while a $270 million exploit shows how much value can be at stake when a weakness is abused.
Removing a feature, however, is not a trivial step. Applications and tools built around it could need to change, which is why such proposals usually involve debate within the developer community before any decision is made.
What comes next
The proposal is at the discussion stage, and no decision has been reported. Whether Solana's community backs the removal, and on what timeline, will determine how the change affects developers building on the network.
