According to ChainCatcher citing CoinDesk, Solana developers have proposed eliminating persistent nonce transactions, a feature used in the April attack on trading protocol Drift that resulted in losses of at least $270 million. The proposal still requires technical approval and could take effect on mainnet as early as May 5, 2027.

Persistent nonces allow signed transactions to remain valid for extended periods, enabling custodians and exchanges to sign transactions offline. Affected organizations will need to migrate to alternatives, and Solana Foundation migration requirements could push back the final deadline.
