Solana Proposal Would Phase Out Durable Nonces
Solana developers are seeking to remove transaction nonces as renewed scrutiny follows the $270 million Drift hack.
Solana developers are seeking to remove transaction nonces as renewed scrutiny follows the $270 million Drift hack. Solana (SOL) is trading at $86.77, up 0.3% since this brief published. This is an original TLT brief synthesising 3 outlets (Crypto Economy, CryptoNews, Unchained), plus live market data, as of Mon, 09 Nov 2026 20:30:07 UTC.
The proposal would eliminate a mechanism for keeping signed transactions valid beyond the standard blockhash window, changing how Solana transactions are constructed and processed. It comes as confidence in the ecosystem is being tested by a major hack and broader concerns around Pump.fun fees and transparency.
- SIMD-0723 would require recent blockhashes and disable nonce-account instructions.
- The proposal follows renewed scrutiny following the reported $270 million Drift hack.
- Drift TVL stands at $241.71 million, down 8% over seven days.
- SOL trades at $86.55, down 2.89% over 24 hours and 7.73% over seven days.
Crypto Economy and CryptoNews both report that Solana developers have proposed retiring or removing durable nonces. Crypto Economy provides the proposal’s specific mechanics and identifies it as SIMD-0723, opened on November 5, while CryptoNews emphasizes its timing after the reported $270 million Drift hack and amid Pump.fun backlash over fees and influencer transparency. The outlets do not contradict each other, but CryptoNews adds the broader industry context absent from the more technical Crypto Economy summary.

Solana developers have opened SIMD-0723 to remove durable nonces, a transaction feature that allows signed transactions to remain valid beyond Solana’s normal blockhash window. The proposal was opened on November 5, according to Crypto Economy, which describes the change as eliminating an alternative to using a recent, short-lived blockhash for every transaction.
Under the proposal, transactions would be required to use a recent blockhash, and the System Program instructions used to manage nonce accounts would be disabled. Durable nonces currently provide a way to preserve transaction validity when a transaction cannot be submitted within the standard blockhash period; the proposed change would remove that mechanism rather than extend or modify it.
Both Crypto Economy and CryptoNews report the proposal to retire durable nonces. Their emphasis differs: Crypto Economy focuses on the technical design, including SIMD-0723, its opening date, and the proposed restrictions on nonce-account instructions. CryptoNews places the effort in the context of the reported $270 million Drift hack and separate backlash surrounding 
Pump.fun’s fees and influencer transparency, framing the change as part of a wider period of scrutiny.
Drift’s currently verified on-chain TVL is $241.71 million, down 8.0% over seven days according to DeFiLlama. That figure provides current context for the protocol after the reported $270 million incident, but the supplied coverage does not establish the hack’s technical connection to durable nonces. Pump.fun’s fee and transparency debate is likewise a separate concern highlighted by CryptoNews rather than a direct subject of SIMD-0723.
The wider market is also under pressure. Total crypto market capitalization stands at $2.56 trillion, with the overall market broadly down; 
Bitcoin is down 1.70% over 24 hours and the Fear & Greed index is at 29, indicating fear. Solana trades at $86.55, down 2.89% over 24 hours and 7.73% over seven days, while PUMP is down 10.19% over seven days. If SIMD-0723 advances, the key implementation points to monitor are the recent-blockhash requirement and removal of nonce-account instructions.
Since this brief published about 8 hours ago, Solana (SOL) has moved from $86.55 to $86.77 — +0.25%.
The chart plots SOL's price: grey is the move before this brief published, the vertical dashed line marks the moment it published, the horizontal dashed line is the price then, and the coloured area is the move since — from TLT's market data (daily resolution). It shows what happened after the news, not that the news caused it; many factors move prices. Not financial advice.
At today's peer-to-peer rate, 1 SOL ≈ ₦120,172.98 (about $86.77), down 2.9% over 24 hours. The naira itself trades about 2.9% above the official rate on the P2P market, so a Nigerian buyer's effective cost differs from the headline dollar price.
