Replace full eager preallocation in the SWQOS serializer with a bounded\nprewarm and lazy growth strategy.\n\n- Prewarm only a small hot set of buffers instead of allocating all\n 10,000 upfront\n- Keep the same max pool capacity and buffer size to preserve the\n original buffer-pool design in steady state\n- Stop zero-filling each buffer during initialization; reserve capacity\n and grow data on demand\n- Return temporary buffers in Base64Encoder::serialize_and_encode to\n avoid pool depletion\n- Add tests for bounded prewarm and lazy allocation/return behavior\n\nWhy:\nThe previous Lazy initialization allocated and touched ~2.44 GiB\n(10,000 x 256 KiB) on first use, which can block the first buy submit\npath and produce a large cold-start latency spike.\n\nValidation:\n- cargo fmt --all\n- cargo check --lib\n- cargo check (SolBot workspace with path dependency)
- 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
- Add pumpfun_copy_trading and pumpfun_sniper_trading to workspace members
- Add grpc_recv_us field to all TradeBuyParams/TradeSellParams in examples
- Switch address_lookup and nonce_cache to sol-parser-sdk, use event is_cashback_coin
- Remove invalid rustls call from pumpfun examples for successful build
- All 18 examples pass cargo check --workspace
Made-with: Cursor
- Bump version to 3.5.4; update README and README_CN
- Astralane: irisb binary API (no Base64), POST /irisb with query api-key&method; constants use /irisb endpoints; ping POST getHealth
- BlockRazor: Send Transaction v2 (plain Base64 body, Content-Type text/plain, auth in URI only); ping POST /v2/health; use default_http_client_builder
- SWQOS: all clients use default_http_client_builder (nextblock, temporal, zeroslot, astralane, lightspeed, jito, flashblock); remove unused Duration imports
Made-with: Cursor
These examples depend on a local path to sol-parser-sdk which is not
available in the public repo, causing build failures for consumers.

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.

- Make serialize_transaction_and_encode sync and route through buffer pool
(serialization::serialize_transaction_sync) to cut allocs on hot path
- Build single-submit body with format! instead of json!+to_string() in bloxroute
- Add serialize_transactions_batch_sync; bloxroute batch uses it and format! for entries
- Fix first-submit cold start: immediate first ping, then 30s keepalive interval
- Fix high latency after ~5 min: pool_max_idle_per_host=4, pool_idle_timeout=300s
(BlockRazor, Temporal, Node1, Astralane, Stellium) so submit reuses ping connection
- Ping: 1.5s timeout, consume response body so connection returns to pool
- poll_transaction_confirmation: avoid cloning status.value[0], use ref
- Translate all swqos comments to English

- PumpFunParams/BondingCurve: from_trade/from_dev_trade take is_cashback_coin parameter
- pumpfun_copy_trading and pumpfun_sniper_trading use sol-parser-sdk for gRPC, pass e.is_cashback_coin
- address_lookup/nonce_cache call sites updated; README EN/CN Cashback and example notes

In `examples/cli_trading/src/main.rs` line 1093, the print statement uses `{}` but `signature` is now `Vec<Signature>` which doesn't implement `Display`.
Error:
error[E0277]: Vec<Signature> doesn't implement std::fmt::Display
Fix: Change `{}` to `{:?}`
// Before
println!(" ✅ Transaction Signature: {}", signature);
// After
println!(" ✅ Transaction Signature: {:?}", signature);
This was likely missed when updating the sell return type from single Signature to Vec.
Updates all examples to use client.infrastructure.rpc instead of
client.rpc following the shared infrastructure refactor in PR #66.
Fixes#70

Previously Soyas returned early on successful send without:
- Any logging
- Polling for transaction confirmation
Now aligned with other SWQOS clients (zeroslot, lightspeed, etc.):
- Proper error handling with reconnect retry
- Always poll for transaction confirmation
- Log confirmation success/failure with elapsed time

Introduce TradingInfrastructure to allow multiple wallets to share the same
RPC client and SWQOS clients, reducing initialization overhead and memory usage.
Changes:
- Add InfrastructureConfig struct for wallet-independent configuration
- Add TradingInfrastructure struct to hold shared RPC/SWQOS clients
- Refactor TradingClient to use Arc<TradingInfrastructure>
- Add from_infrastructure() for fast client creation from shared infrastructure
- Add from_infrastructure_with_wsol_setup() for async WSOL ATA setup
- Maintain backwards compatibility with existing TradingClient::new() API
Benefits:
- First wallet: Full initialization (~200-500ms)
- Subsequent wallets (same config): Fast creation (~1-2ms)
- Memory: Single set of RPC/SWQOS clients shared across wallets
Remove obsolete data_size_limit parameters from all gas fee strategy function calls in documentation and examples, following the recent API changes.

- Update all example files using set_global_fee_strategy (from 8 params to 6 params)
- Update gas_fee_strategy example for set_normal_fee_strategy and set_high_low_fee_strategy
- Remove the last two parameters (256 * 1024, 0) from all calls
