Solana developers have put forward a draft proposal to scrap "durable nonces," the transaction feature used in the $270 million hack of the Drift protocol. According to the draft, the feature would be removed no earlier than May 5, 2027.

Who is affected

Durable nonces let a transaction be signed ahead of time and submitted later, which is why the feature is common in offline signing setups. Removing it would force custodians that sign offline to rebuild how they move coins on the network.

The proposal is a draft, so the design and timeline could still change before anything is adopted. The May 2027 date is described as the earliest possible point, not a firm deadline, which leaves custodians and other affected teams several months to plan alternatives.

Why it matters

The move shows how a single protocol-level feature can become a security concern once it is linked to a major exploit. A loss of $270 million at Drift has put attention on how transactions are authorized and signed on Solana, and the proposal suggests the network's contributors would rather remove the mechanism than keep it in place.

The trade-off is operational. Institutions that rely on air-gapped or offline signing for security will have to change their workflows, and any such change carries its own risk if it is rushed.

The draft now moves into discussion among Solana's developer and validator community. Because the earliest removal date is May 5, 2027, custodians have time to engage with the proposal and prepare replacement signing flows.
