Solana Network to Activate SIMD-0242 Restricting Nonce Account Usage
12/02/2025, 20:06
AI SUMMARY
●Solana developers announce activation of SIMD-0242 to restrict nonce account patterns
●Update requires nonce accounts to be directly specified in transactions
●Builders urged to update integrations to avoid potential transaction failures
The Solana Developers ecosystem has announced that SIMD-0242 is next in line for activation on the network. This update will officially disable the usage of loading nonce accounts from Address Lookup Tables (ALTs), a practice that needs to be discontinued to ensure transaction stability.
Developers are urged to update their integrations immediately. Moving forward, nonce accounts must be directly specified in the transaction message rather than being resolved through lookups. Failure to update could result in transaction issues once the feature is activated.
