- 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

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

- 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

When using multiple SWQOS channels with durable nonce, if one channel's
transaction lands on-chain but fails (e.g., ExceededSlippage), the nonce
is consumed and other channels cannot succeed.
Previously, the SDK would wait for all channels to timeout (~15s) before
returning, and would often return a generic "timeout" error instead of
the actual on-chain error.
This fix:
- Adds `landed_on_chain` field to TaskResult to track if tx landed
- Adds `is_landed_error()` to detect on-chain failures vs timeouts
- Adds `landed_failed_flag` to ResultCollector for early exit signaling
- Returns immediately with the actual error when a tx lands but fails
This makes behavior consistent with the success case - both return
immediately once the nonce is consumed.
Benefits:
1. Get the actual error (e.g., ExceededSlippage) instead of timeout
2. Return in ~1s instead of ~15s
3. Enable faster retry logic for callers

Fixed a critical bug in find_by_base_mint and find_by_quote_mint functions
where pool data decoding failed because the 8-byte discriminator was not
being skipped. This caused all PumpSwapParams::from_mint_by_rpc calls to
fail with "No valid pool decoded" error.
Changes:
- Modified find_by_base_mint to skip discriminator: pool_decode(&acc.data[8..])
- Modified find_by_quote_mint to skip discriminator: pool_decode(&acc.data[8..])
- Added data length check to prevent out-of-bounds access
- Aligned with fetch_pool function which correctly uses &account.data[8..]
