v4.0.11 switched the fast-submit (`wait_tx_confirmed = false`) result loop
from `wait_for_all_submitted` to `wait_for_first_submitted`. The new
function returns as soon as one SWQOS route's HTTP submit completes and
drains whatever signatures are in `ResultCollector.results` at that
moment — slower routes' signatures arrive after the caller has returned.
This is correct for fire-and-forget low-latency submits, but breaks
callers that do their own on-chain confirmation against a pinned durable
nonce. Only one of the submitted txs can land (nonce is consumed by
whichever lands first), but the caller has no way of knowing in advance
which route it will be. Their post-submit logic feeds every returned
signature to `getSignatureStatuses` to find the landed one — with only
the fastest HTTP responder returned (often not the one that lands), the
landed tx isn't in the polled set.
Adds an opt-in `SwapParams.wait_for_all_submits: bool` (default false,
plumbed through `TradeBuyParams` / `TradeSellParams`). When true and
`wait_tx_confirmed = false`, `execute_parallel` uses
`wait_for_all_submitted` (still in the codebase, was
`#[allow(dead_code)]`) so every submitted signature is returned. Zero
behaviour change for current users.
Sync supported DEX IDLs from bitquery/solana-idl-lib, upgrade protocol builders, and keep trade submission hot paths free of RPC query calls.
Include exact-output coverage, token-account setup fixes for WSOL and stable pairs, and low-latency transaction build improvements.

when AMM protocol fee pubkey is used).
- Add is_mayhem_fee_recipient and is_amm_fee_recipient helpers in pumpfun utils.
- Bump solana-* crates to 3.1.12; align tonic/prost; use solana-message for
AddressLookupTableAccount; add solana-system-interface 3.0.
- Update examples and latency script for new PumpFunParams signature.
- SWQoS and transaction builder adjustments for dependency changes.

主要解决问题：
当 wait_tx_confirmed 参数为 false 时，SUBMIT_TIMEOUT_SECS 等待改为2秒，要么全部提交完成返回，要么不等待提交未返回的交易，方便快速创建交易订单。
#Let the SDK print submit_timing data (SwqosType and submission time) and return it to the buy and sell methods.
Main problems solved:
When the wait_tx_confirmed parameter is false, the SUBMIT_TIMEOUT_SECS wait is changed to 2 seconds. Either all submissions are completed and returned, or the unreturned transactions are not waited for submission, which facilitates the rapid creation of transaction orders.
- Rename wait_transaction_confirmed to wait_tx_confirmed (params, lib, docs, examples)
- SDK timing: use [SDK][provider] style with fixed-width labels; add newline before block
- Move print_sdk_timing_block to common::sdk_log; unify SWQOS_LABEL_WIDTH
- SWQOS submitted/failed: aligned [Provider] labels via log_swqos_submitted/submission_failed
- Extract short error message from JSON (message/data) or quoted string; prefix with 'error: '
- Format elapsed as 'X.XXXX ms' or 'X.XXXX µs' (4 decimals, space before unit); use comma before error
- Add SwqosType::as_str() for zero-allocation log labels; only parse JSON when input starts with '{'

- Bump version to 3.6.4 in Cargo.toml
- Update version references in README.md and README_CN.md
- Add RELEASE_v3.6.4.md with English release notes
- All workspace examples verified to compile (cargo build --workspace)
- Remove RELEASE_v3.6.3.md and docs/ASYNC_EXECUTOR_REVIEW.md
- Minor updates in types, lib, transaction_builder, async_executor, executor, params
Made-with: Cursor
- transaction_pool: add PARALLEL_SENDER_COUNT (18), ensure prefill >= 18 so
multi-channel build never serializes; prefill 64 with max(PREFILL, 18)
- async_executor: document that pool prefill must match sender thread count
- executor: do not sort submit_timings (avoids any extra work); comment that
log order is completion order
- docs: add ASYNC_EXECUTOR_REVIEW.md
- remove RELEASE_NOTES_v3.6.2.md; minor example/types/lib/params updates
Made-with: Cursor
- Log build_instructions / before_submit once; per-channel submit, confirmed, total (all from grpc_recv_us)
- confirmed = per-channel submit-to-confirm duration; total = batch start-to-confirm when need_confirm
- No logging between execute_parallel and poll_any_transaction_confirmation to reduce latency
- Clone submit_timings only when log_enabled; all logging after result is ready
- Use provider name (Jito, Helius, etc.) in log lines instead of generic SWQOS
- Timing format: .4 ms; simulate (dry-run) label for simulate mode
- execute_parallel returns 4-tuple with submit_timings for per-channel timing
Made-with: Cursor
- Add Helius Sender client (helius.rs) with dual routing and swqos_only mode
- Helius min tip: 0.0002 SOL default, 0.000005 SOL when swqos_only=true
- Add TradeConfig.check_min_tip (default false) to skip min-tip validation for lower latency
- Thread check_min_tip through SwapParams and execute_parallel; only call min_tip_sol when enabled
- Add SWQOS_ENDPOINTS_HELIUS and HELIUS_TIP_ACCOUNTS in constants
- Extend SwqosConfig/SwqosType for Helius; add Helius to get_endpoint and get_swqos_client
- Update trading_client, shared_infrastructure and middleware_system examples
Made-with: Cursor
In v3.5.0, confirmation was split out of execute_parallel into
poll_transaction_confirmation, but it only polled sig[0]. When
multi-channel submit is used, each channel produces a different
signature and only one lands on-chain. If the landed sig is not
sig[0], the poll times out after 15s and reports failure despite
a successful on-chain transaction.
Add poll_any_transaction_confirmation() that passes all signatures
to get_signature_statuses in a single RPC call per poll, returning
the first one that confirms. The executor now uses this instead of
polling a single signature.
