Struct NonceSender 

pub struct NonceSender { /* private fields */ }

Shared nonce manager — all tx sends go through this to avoid nonce collisions.

Wraps a type-erased provider (DynProvider) so it’s a plain concrete type. Callers should wrap this in Arc<Mutex<NonceSender>> and lock before each send.

Auto-recovery

On nonce-related errors, the sender automatically syncs the nonce from chain and retries once before returning an error.

Implementations

impl NonceSender

pub async fn new(provider: DynProvider, signer_addr: Address) -> Result<Self>

Create a new NonceSender, fetching the current nonce from chain.

pub async fn sync(&mut self) -> Result<()>

Re-fetch nonce from chain (use after errors).

pub fn current_nonce(&self) -> u64

Current local nonce value.

pub async fn send(&mut self, tx: TransactionRequest) -> Result<PendingTx>

Send a transaction, stamping it with the next nonce.

On nonce-related errors: syncs from chain and retries once. The returned PendingTx can be .awaited for the receipt after releasing the Mutex lock.
