 When using multiple MEV services, you need to use `Durable Nonce`. You need to use the `fetch_nonce_info` function to get the latest `nonce` value, and use it as the `durable_nonce` when trading.

+#### Astralane QUIC (Low-Latency)
+
+Astralane supports both HTTP and **QUIC** transport. QUIC reduces connection overhead and can lower submission latency. To use the QUIC channel, pass `Some(SwqosTransport::Quic)` as the fourth parameter of `SwqosConfig::Astralane`. Astralane’s QUIC service uses a **single endpoint** (no per-region endpoints); the SDK ignores the `region` (and optional custom URL) when QUIC is selected. You can pass the same region as your other SWQoS configs for consistency.
+
+```rust
+use sol_trade_sdk::{SwqosConfig, SwqosRegion, SwqosTransport};
+
+// Astralane over QUIC (low-latency); region is ignored (single QUIC endpoint)
+let swqos_configs: Vec<SwqosConfig> = vec![

+        None,
+        Some(SwqosTransport::Quic),
+    ),
+];
+// Then create TradeConfig / TradingClient as usual with swqos_configs
+```
+
+- **HTTP** (default): use `None` or `Some(SwqosTransport::Http)`; region and optional custom URL apply.
+- **QUIC**: use `Some(SwqosTransport::Quic)`; the SDK uses a single QUIC endpoint and ignores region. Same API key as HTTP.

 ### 🔧 Middleware System
@@ -289,6 +335,24 @@ PumpFun and PumpSwap support **cashback** for eligible tokens: part of the tradi
 - The **pumpfun_copy_trading** and **pumpfun_sniper_trading** examples use sol-parser-sdk for gRPC subscription and pass `e.is_cashback_coin` when building params.
 - **Claim**: Use `client.claim_cashback_pumpfun()` and `client.claim_cashback_pumpswap(...)` to claim accumulated cashback.

+#### PumpFun: Creator Rewards Sharing (creator_vault)
+
+Some PumpFun coins use **Creator Rewards Sharing**, so the on-chain `creator_vault` can differ from the default derivation. If you reuse cached params from a **buy** when **selling**, you may see program error **2006 (seeds constraint violated)**. To avoid this:
+
+- **From gRPC/events (no RPC needed)**: You can get both `creator` and `creator_vault` from parsed transaction events:
+  - **sol-parser-sdk**: Before pushing events, the pipeline calls `fill_trade_accounts`, which fills `creator_vault` from the buy/sell instruction accounts (buy index 9, sell index 8). `creator` comes from the TradeEvent log. Use `PumpFunParams::from_trade(..., e.creator, e.creator_vault, ...)` or `from_dev_trade(..., e.creator, e.creator_vault, ...)` with the event `e`.
+  - **solana-streamer**: Instruction parsers set `creator_vault` from accounts[9] (buy) or accounts[8] (sell); `creator` comes from the merged CPI TradeEvent log. Use the same `from_trade` / `from_dev_trade` with `e.creator` and `e.creator_vault`.
+- **Override after RPC**: If you get params via `PumpFunParams::from_mint_by_rpc` but later receive a newer `creator_vault` from gRPC, call `.with_creator_vault(latest_creator_vault)` on the params before selling.
+
+The SDK does not fetch creator_vault from RPC on every sell (to avoid latency); pass the up-to-date vault from gRPC/events when available.
+
+#### PumpSwap: coin_creator_vault from events (no RPC)
+
+For **PumpSwap** (Pump AMM), `coin_creator_vault_ata` and `coin_creator_vault_authority` are required in buy/sell instructions. Both are available from parsed events without RPC:
+
+- **sol-parser-sdk**: Instruction parser sets them from accounts 17 and 18; the account filler also fills them when the event comes from logs. Use `PumpSwapParams::from_trade(..., e.coin_creator_vault_ata, e.coin_creator_vault_authority, ...)` with the buy/sell event `e`.
+- **solana-streamer**: Instruction parser sets them from `accounts.get(17)` and `accounts.get(18)`. Use the same `from_trade` with the event’s `coin_creator_vault_ata` and `coin_creator_vault_authority`.

+## ⏱️ Timing metrics (v3.5.0+)
+
+When `log_enabled` and SDK log are on, the executor prints `[SDK] Buy/Sell timing(...)`. **Semantics changed in v3.5.0**: `submit` is now only the send to SWQOS/RPC; `confirm` is separate; `start_to_submit` (when `grpc_recv_us` is set) is **end-to-end from gRPC event to submit**, so it is larger than in-process timings.

+
+- **来自 gRPC/事件（无需 RPC）**：`creator` 与 `creator_vault` 均可从解析后的事件中直接拿到：
+  - **sol-parser-sdk**：推送前会调用 `fill_trade_accounts`，从 buy/sell 指令账户补全 `creator_vault`（buy 索引 9，sell 索引 8）；`creator` 来自 TradeEvent 日志。用 `PumpFunParams::from_trade(..., e.creator, e.creator_vault, ...)` 或 `from_dev_trade(..., e.creator, e.creator_vault, ...)` 即可。

+## sol-trade-sdk v4.0.2
+
+This release focuses on QUIC reliability and low-latency submission stability for Astralane.
+
+### Highlights
+
+- Fixed Astralane QUIC address-family mismatch that could produce `invalid remote address` when DNS returned IPv6 first and local endpoint was IPv4-only.
+- Added remote-family-aware local QUIC bind selection:
+  - IPv4 remote -> bind `0.0.0.0:0`
+  - IPv6 remote -> bind `[::]:0`
+- Added Astralane direct-IP candidate support (official region IPs), with IPv4-first selection for better QUIC stability.
+- Added automatic endpoint failover and reconnect rotation across candidate addresses, reducing single-endpoint/DNS variance impact.
+- Kept existing SDK interfaces compatible while improving submit-path resiliency.
+
+### Also included from recent updates
+
+- BlockRazor gRPC endpoint fixes and gRPC default transport behavior improvements (v4.0.1).
+- SWQOS transport path hardening and Binary-Tx response handling improvements (v4.0.0).

+# sol-trade-sdk 代码审查报告
+
+审查维度：**逻辑准确性**、**可读性**、**模块化**、**超低延迟**、**代码质量**、**安全性**。
+
+---
+
+## 1. 代码逻辑准确性
+
+### 1.1 Instruction 与 IDL / 官方行为
+
+| 模块 | 结论 | 说明 |
+|------|------|------|
+| PumpFun buy/sell | ✅ 一致 | 账户顺序、discriminator、track_volume 与 `idl/pump.json` 一致；cashback 时 remainingAccounts 顺序正确 |
+| PumpSwap buy/sell | ✅ 一致 | 与 `idl/pump_amm.json` 一致；sell cashback 使用 quote_mint ATA |
+| PDA 推导 | ✅ 一致 | bonding_curve_v2、pool_v2、user_volume_accumulator、creator_vault 等 seeds 与官方一致 |
+
+### 1.2 需修正的逻辑/风格
+
+- **`src/instruction/utils/pumpswap.rs` 约 258、291 行**：`let program_id: &Pubkey = &&accounts::AMM_PROGRAM` 为双重引用，易误导且多余。建议改为 `&accounts::AMM_PROGRAM`。
+
+---
+
+## 2. 代码可读性
+
+### 2.1 命名与注释
+
+- 多数模块有中英文注释，instruction 与 IDL 的对应关系有标注。
+- **建议**：`src/instruction/pumpfun.rs` 约 259 行 sell 的 discriminator 使用魔法数组 `[51, 230, 133, ...]`，建议改为 `SELL_DISCRIMINATOR` 常量（与 buy 路径一致）。
+
+### 2.2 错误信息与文案
+
+- **建议**：`src/lib.rs` 中 “Current version only support” 应为 “only supports”；类似拼写/语法可统一检查。
+
+### 2.3 过长函数
+
+- **建议**：`src/lib.rs` 的 `ensure_wsol_ata` 可拆为「入口 + 重试循环」与「单次尝试 + 结果判断」，便于单测和阅读。
+
+---
+
+## 3. 模块化
+
+### 3.1 职责与分层
+
+- **instruction**：按协议分（pumpfun / pumpswap / bonk / raydium_* 等），实现 `InstructionBuilder`，边界清晰。
+- **instruction/utils**：PDA、常量、类型、池子解析与上层「组指令」分工明确。
+- **swqos**：按提供商分模块，common 放序列化、确认轮询、HTTP 客户端，无循环依赖。
+- **结论**：分层合理，模块化良好。
+
+---
+
+## 4. 超低延迟
+
+### 4.1 必须改：避免多余 clone
+
+| 位置 | 问题 | 建议 |
+|------|------|------|
+| `src/instruction/pumpswap.rs` 约 232、429 行 | `Instruction { accounts: accounts.clone(), data }` 对已拥有的 `Vec<AccountMeta>` 做完整 clone | 改为直接移动：`Instruction { program_id, accounts, data }`，不再 clone |
+
+### 4.2 建议
+
+- 若多路 SWQOS 并发发**同一笔**交易，可在调用方序列化一次，再传 `&[u8]` 给各 client，减少重复 bincode 序列化。
+- 热点路径未见不必要的 `Mutex`/`RwLock` 竞争，当前设计可接受。
+
+---
+
+## 5. 代码质量
+
+### 5.1 必须改：避免 panic 的 unwrap
+
+以下 PDA 或关键 `Option` 使用 `.unwrap()`，在异常输入下会直接 panic，建议改为 `Result` 并向上传播错误：
+
+| 文件 | 行号（约） | 说明 |
+|------|------------|------|
+| `src/instruction/pumpfun.rs` | 67, 101, 149, 221, 291, 295 | `get_bonding_curve_pda`、`get_user_volume_accumulator_pda`、`get_bonding_curve_v2_pda` |
+| `src/instruction/pumpswap.rs` | 184, 198, 385, 407 | `get_user_volume_accumulator_pda`、`get_pool_v2_pda` |
+| `src/instruction/utils/pumpfun.rs` | 229 | `DEFAULT_CREATOR_VAULT.unwrap()`（LazyLock 未初始化时可能 panic） |
+| `src/instruction/bonk.rs` | 多处 | `get_pool_pda`、`get_vault_pda`、`params.rpc.as_ref().unwrap()` |
+| `src/instruction/utils/bonk.rs` | 110–116, 148–152 | `checked_*` 链后 `.unwrap()`，数学假设不成立会 panic |
+| `src/instruction/raydium_cpmm.rs` | 46, 106, 189, 250 | PDA / 状态相关 unwrap |
+| `src/instruction/utils/raydium_cpmm.rs` | 83, 85, 141 | `get_vault_pda(...).unwrap()` |
+
+**建议**：统一改为 `.ok_or_else(|| anyhow!("..."))?` 或返回 `Result`，在调用链顶层处理错误，避免进程退出。
+
+### 5.2 建议
+
+- **测试**：为 instruction 构建（或至少 PDA + discriminator/data 布局）增加单元测试，固定输入与预期 bytes/accounts 比对，便于 IDL 升级时回归。
+- **错误类型**：`claim_cashback_*` 等返回 `Option<Instruction>`；可考虑统一为 `Result<Instruction>` 并带“无法构建”原因，或在文档中明确 None 的语义。
+
+---
+
+## 6. 安全性
+
+### 6.1 必须改：API key 不得写入日志
+
+| 位置 | 问题 | 建议 |
+|------|------|------|
+| `src/swqos/astralane_quic.rs` 约 61 行 | `info!(..., "api_key as CN: {}", api_key)` | 移除 api_key 或改为占位（如 `***` / 仅长度） |
+| `src/swqos/astralane_quic.rs` 约 74 行 | `info!(..., "Connected at {} (api_key: {})", addr, api_key)` | 同上 |
+
+### 6.2 必须改：SkipServerVerification 风险
+
+| 位置 | 问题 | 建议 |
+|------|------|------|
+| `src/swqos/astralane_quic.rs` 约 179–181 行 | `with_custom_certificate_verifier(SkipServerVerification)` 完全跳过服务端证书校验 | 1）若服务端提供证书：用 `RootCertStore` 或固定证书做校验；2）若仅 dev/内网：用 feature 或配置限制，并在文档/日志中明确“仅受控环境使用”；3）默认/生产构建建议不跳过校验 |
+
+### 6.3 建议
+
+- **敏感配置**：确保生产环境从环境变量或安全配置读取 API key，并在文档中说明。
+- **依赖**：定期执行 `cargo audit` 与依赖升级。
+- **unsafe**：`perf/hardware_optimizations.rs`、`realtime_tuning.rs` 中的 `unsafe` 使用范围可控，需保持注释中的安全约定。
+
+---
+
+## 7. 三库联动与超低延迟检查（sol-trade-sdk / sol-parser-sdk / solana-streamer）
+
+### 7.1 逻辑一致性（已确认）
+
+| 检查项 | sol-parser-sdk | solana-streamer | 说明 |
+|--------|----------------|-----------------|------|
+| Pump buy 账户数 | 16（fill 用 get(9) 填 creator_vault） | 16，accounts[9]=creator_vault | 与 idl/pumpfun.json 一致 |
+| Pump sell 账户数 | 14（get(8)=creator_vault） | 14，accounts[8]=creator_vault | 一致 |
+| PumpSwap buy 17/18 | 指令解析 + fill_buy_accounts get(17)/get(18) | 指令解析 accounts.get(17)/get(18) | coin_creator_vault_ata/authority 正确 |
+| PumpSwap sell 17/18 | fill_sell_accounts 同左 | 同左 | 一致 |
+| 填充顺序 | 先 parse（log 或 instruction）→ fill_accounts → push | 指令解析直接写 17/18；无单独 fill 步骤 | 两者均保证事件带齐 creator_vault / coin_creator_vault |
+| find_instruction_invoke | 选「账户数最多」的 invoke，保证取到 outer buy/sell | N/A（按当前 instruction 解析） | 正确 |
+
+### 7.2 版本化交易账户解析
+
+- **sol-parser-sdk**：`get_instruction_account_getter` 正确支持 versioned tx：先 `account_keys`，再 `loaded_writable_addresses`，再 `loaded_readonly_addresses`，与 Solana 约定一致。
+- **solana-streamer**：指令的 `accounts` 为索引，通过 `accounts.get(idx as usize).copied()` 从完整 `accounts: &[Pubkey]` 解析；调用方需传入已包含 loaded 的完整账户列表，否则高索引会得到 `default()`。
+
+### 7.3 超低延迟相关
+
+| 项目 | 状态 / 建议 |
+|------|-------------|
+| solana-streamer 热路径 | 已改为**顺序执行** inner 解析与 swap_data 提取，去掉 `thread::scope` + 双 spawn/join，减少 μs 级开销。 |
+| sol-parser-sdk | log 与 instruction 并行（rayon::join）；fill 仅在有 invoke 时做；`find_instruction_invoke` 为 O(invokes)，单程序单 tx 下可接受。 |
+| sol-trade-sdk | 见上文第 4 节；PumpSwap instruction 构建避免 `accounts.clone()` 已列为必须改。 |
+
+### 7.4 建议
+
+- **solana-streamer**：若 gRPC 上游已提供完整 `accounts`（含 loaded），可避免对每笔 tx 做 `accounts.to_vec()`，仅在需要 resize 时克隆，进一步降低分配。
+- **三库**：保持 IDL 与账户索引注释同步（pumpfun.json / pump_amm.json），避免后续扩展时索引错位。
+
+---
+
+## 8. 汇总：必须改 vs 建议改
+
+### 必须改（优先处理）
+
+| 序号 | 项 | 位置 |
+|------|----|------|
+| 1 | 移除 astralane_quic 中 API key 的日志输出 | `src/swqos/astralane_quic.rs` 61、74 行 |
+| 2 | SkipServerVerification：改为证书校验或仅限 dev 并文档化 | `src/swqos/astralane_quic.rs` 179–181 行 |
+| 3 | instruction 中 PDA 等 `.unwrap()` 改为 `Result` 并传播错误 | pumpfun.rs、pumpswap.rs、pumpfun/utils、bonk、raydium_cpmm 等 |
+| 4 | PumpSwap 构建 instruction 时避免 `accounts.clone()`，改为移动 | `src/instruction/pumpswap.rs` 232、429 行 |
+
+### 建议改（可分批）
+
+| 序号 | 项 | 位置 |
+|------|----|------|
+| 5 | PDA 的 `program_id` 从 `&&AMM_PROGRAM` 改为 `&AMM_PROGRAM` | `src/instruction/utils/pumpswap.rs` 258、291 行 |
+| 6 | PumpFun sell discriminator 改为命名常量 | `src/instruction/pumpfun.rs` 约 259 行 |
+| 7 | `ensure_wsol_ata` 拆分；修正 “only support” 等文案 | `src/lib.rs` |
+| 8 | 为 instruction 构建与 PDA 增加单元测试 | 新建 tests 或模块下 |
+| 9 | 生产日志用 tracing 替代 println!/eprintln! | `src/swqos/astralane.rs` 等 |

-# sol-trade-sdk v3.4.1
-
-Rust SDK for Solana DEX trading (Pump.fun, PumpSwap, Raydium, Bonk, Meteora, etc.).
-
-## What's Changed
-
-### New Features
-
- **PumpFun & PumpSwap Cashback** (#77): Support for cashback in PumpFun and PumpSwap trading flows. See [Cashback documentation](docs/PUMP_CASHBACK_README.md).
- **Events**: `is_cashback_coin` is now passed from events; PumpFun examples use `sol-parser-sdk` only for event parsing.
-
-### Performance
-
- **SWQoS**: Reduced submit latency; fixed high latency after ~5 minutes idle.
-
-### Bug Fixes
-
- **WSOL ATA**: WSOL Associated Token Account creation now runs in background with retry and timeout for more reliable setup.
- Silenced unused and deprecated compiler warnings.
-
-### Documentation
-
- README (EN/中文): Added Cashback section, outline, examples and tables.
- Updated crates.io / docs references in README.

-# sol-trade-sdk v3.5.0
-
-Rust SDK for Solana DEX trading (Pump.fun, PumpSwap, Raydium, Bonk, Meteora, etc.).
-
-## What's Changed
-
-### Performance
-
- **Executor hot path**: Sample `Instant::now()` only when `log_enabled` or `simulate` (total, build, submit, confirm) to reduce cold-path syscalls.
- **SWQOS**: `execute_parallel` now takes `&[Arc<SwqosClient>]` to avoid cloning the client list on each swap.
- **Constants**: Named constants for instruction/account sizes and HTTP client timeouts; no magic numbers in hot paths.
-
-### Code Quality
-
- **Protocol params**: Single `validate_protocol_params()` used for both buy and sell; removed duplicate match blocks in `lib.rs`.
- **Comments**: Bilingual (English + 中文) doc and inline comments across execution, executor, perf (hardware_optimizations, syscall_bypass), and swqos/common.
- **Prefetch/safety**: Clearer docs for cache prefetch and `unsafe` usage (valid read-only ref, no concurrent write).
-
-### Documentation
-
- README (EN/CN): Version references updated to 3.5.0 for path and crates.io usage.

+# Proto 生成的代码说明
+
+## 概述
+
+这个目录包含了从 `.proto` 文件预生成的 Rust 代码。
+
+## 文件说明
+
+- `serverpb.rs` - 从 `blockrazor.proto` 生成的 gRPC 代码
+  - 消息类型: `SendRequest`, `SendResponse`, `HealthRequest`, `HealthResponse`
+  - gRPC 客户端: `server_client::ServerClient`
+  - gRPC 服务端: `server_server::Server`
+
+## 用户使用
+
+用户**不需要**安装 `protoc` 或编译 proto 文件。这些代码已经预生成好了，可以直接使用。
+
+在 `blockrazor.rs` 中使用：
+```rust
+pub mod serverpb {
+    include!("pb/serverpb.rs");
+}
+```
+
+## 开发者如何重新生成代码
+
+如果你修改了 `.proto` 文件并需要重新生成代码：
+
+```bash
+cd sol-trade-sdk/proto/gen
+cargo run
+```
+
+这会在 `src/swqos/pb/serverpb.rs` 生成新的代码。
+
+## 技术细节
+
+生成工具使用 `tonic-prost-build` crate：
+- 输出目录: `src/swqos/pb`
+- Proto 文件: `proto/blockrazor.proto`
+- 生成工具: `proto/gen/`
+- 包含完整的客户端和服务端代码

 //! Parallel executor for multi-SWQOS submit.

+//! - **Pool**: Pre-spawned workers (default 18); hot path only enqueues jobs (no per-call tokio::spawn).
+//! - **Dedicated threads** (opt-in via `with_dedicated_sender_threads`): N OS threads run sender work only, optionally pinned to cores.
+//! - **Arc**: Shared data behind `Arc` → clone = refcount increment (no data copy).
+//! - **Refs**: `build_transaction` takes refs only; worker path avoids extra clones.
+//!
+//! **Core affinity & latency:** Each job is assigned a core (round-robin from `effective_core_ids`). When a worker runs a job,
+//! it sets thread affinity to that core. If that core is busy with other work (e.g. node sync, bot logic), SWQOS submit on that
+//! core will compete for CPU and latency can increase. For lowest latency, reserve a subset of cores for SWQOS only via
+//! `with_dedicated_sender_threads(Some(indices))` and avoid running other CPU-heavy work on those core indices.
