[CoinDesk] Solana moves to scrap the transaction feature used in the $270 million Drift hack
Not investment advice. Muhabbit scores how much a story may matter, not which way to trade.
Solana validators are considering a draft proposal to retire durable nonces, the transaction feature exploited in the $270 million Drift hack, with removal targeted for no earlier than May 5, 2027. The mechanism lets signers authorize transactions that can be submitted later, a design that custodians relying on offline signing have built their coin-moving workflows around. Scrapping it would force those custodians to rebuild how they authorize and broadcast transfers. The move matters because it trades a long-standing convenience feature for a smaller attack surface on one of the largest smart-contract chains. What to watch next is validator signaling on the draft and how quickly custody providers and other offline-signing services publish migration plans ahead of the 2027 deadline.
