## Motivation Follow-up to #25074 and #25076 in the effort to reduce PXE↔node RPC traffic. Two calls per sent tx were guaranteed wasted: a pre-send `getTxReceipt` used only to reject settled duplicates, which the node's tx validation already rejects via its double-spend check, and the first receipt poll of `.wait()`, issued immediately after `sendTx` when the tx cannot have been mined yet. ## The change - `BaseWallet.sendTx` no longer reads the receipt before sending; duplicate submissions are rejected by the node instead. - `WaitOpts` gains `initialDelay`: seconds to sleep before the first receipt poll. The wallet defaults it to the poll interval, so the first poll now happens where the second poll used to. Environments where receipts are available immediately after sending (e.g. automine) can pass `initialDelay: 0`. - The delay counts against `timeout` (the deadline is fixed before sleeping) and does not consume the DROPPED-receipt grace period, which starts at the first poll. Wallet benchmark results: | | Before → After | |---|---| | `getTxReceipt` calls | 40 → 32 (−20.0%) | | Total node RPC calls | 232 → 224 (−3.4%) | | Node RPC round trips | 163 → 156 (−4.3%) |
