🚨 SOLANA MOVES TOWARD MAJOR SECURITY CHANGES FOLLOWING $270 MILLION DRIFT EXPLOIT Solana developers have submitted SIMD-0723, a proposal to eliminate durable nonce transactions, which allow signed transactions to remain valid for extended periods. The mechanism was exploited during April's $270 million Drift Protocol attack, where attackers reportedly obtained transaction approvals in advance and executed them later. The proposed change would require transactions to use recent blockhashes, reducing the ability to execute old signed transactions.
