-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.
