Nonce

Durable Nonce Accounts

Normally, Solana transactions require a recent blockhash that expires after about 60-90 seconds. Durable nonces solve this by replacing the recent blockhash with a stored nonce value that never expires until it is used.

Why Use Durable Nonces?

• Offline signing - Sign transactions on an air-gapped machine without worrying about blockhash expiration
• Multi-party signing - Collect signatures from multiple parties over time
• Scheduled transactions - Prepare transactions now and submit them later
• Custodial workflows - Queue transactions that require approval steps before submission

How It Works

1. Create a nonce account that stores a nonce value on-chain
2. Use that nonce value instead of a recent blockhash when building your transaction
3. When the transaction is submitted, the nonce value is automatically advanced so it can't be reused

Operations

• Create Nonce Account - Create a new durable nonce account
• Get Nonce Account - Fetch and read nonce account data
• Use Nonce Account - Send a transaction using a durable nonce
• Never Nonce - Prevent durable nonces in transactions using pinocchio-never-nonce
