Solana moves to scrap durable nonces after $270 million Drift hack
The proposal would force offline custodians to rebuild how they move SOL and may temporarily raise transaction fees as wallets adapt.
Key takeaways
- 1Durable nonces feature slated for removal no earlier than May 5, 2027.
- 2Drift hack exploited the feature to steal $270 million.
Solana’s on-chain governance announced on Wednesday a draft proposal to retire the durable nonces transaction feature that was exploited in the $270 million Drift hack. The change is slated for implementation no earlier than May 5, 2027. Core developers said the move is part of a broader security hardening effort.
Durable nonces let validators and custodians create a reusable transaction identifier for offline signing. The proposal would permanently disable the feature. Custodians that rely on offline signatures must redesign their workflows, rebuild how they move SOL tokens, and update wallet software. This may cause a temporary rise in transaction fees.
Solana is a high-throughput Layer-1 blockchain that ranks seventh by market capitalisation. It is valued at about $50.9 billion, with tokens trading around $86 as of 07:10 UTC on 9 November 2026. YourKhabri previously reported the $270 million Drift exploit, which exposed vulnerabilities in transaction design, and tracked $148 million in whale movements.
Removing durable nonces aims to close a vector that attackers have used. The transition may create short-term operational friction for offline custodians and could affect transaction reliability. Stakeholders will watch the upcoming governance vote and any implementation updates for signs of broader security improvements. Regulators and institutional users are monitoring the change as a potential precedent for other blockchains.
