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.
- Extend SWQOS regional constants to 10 entries (Dublin, Singapore, Default)
so indices match SwqosRegion 0..9 everywhere
- Document geographic nearest-fill among published PoPs; call out Default and
single-PoP provider constraints in comments
- Fix Node1 QUIC Default endpoint to match HTTP; tune ZeroSlot/Blox/Speedlanding
regional mappings where a closer published PoP exists
- Add unit tests for table length and Astralane/Node1 cross-table consistency
- Update SwqosRegion rustdoc, README, and trading_client example accordingly
Made-with: Cursor
- Add `mev_protection: bool` to `TradeConfig` and `InfrastructureConfig` (default: false)
- Astralane QUIC: switches to port 9000 (MEV-protected endpoint) when enabled
- BlockRazor HTTP: uses `mode=sandwichMitigation` query param when enabled
- BlockRazor gRPC: uses `mode=sandwichMitigation` when enabled
- Add `SWQOS_ENDPOINTS_ASTRALANE_QUIC_MEV` constants (port 9000) to `constants/swqos.rs`
- Fix `astralane_quic.rs` IP candidates to use the actual port from the address (supports both 7000 and 9000)
- Refactor `TradeConfig` to builder pattern via `TradeConfig::builder()`
- Introduce `TradeConfigBuilder` with all optional fields and clear defaults
- `TradeConfig::new()` kept as a shortcut (calls `builder().build()`) for backward compatibility
- Remove old `with_wsol_ata_config` / `with_check_min_tip` / `with_swqos_cores_from_end` / `with_mev_protection` chain methods
- Update all 16 examples to use `TradeConfig::builder()` with commented-out options so users can discover all available settings at a glance
- Update README.md and README_CN.md code snippets to use builder pattern

- 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 new `shared_infrastructure` example demonstrating multi-wallet
resource sharing pattern
- Update `trading_client` example to show both initialization methods
- Update README with:
- New feature: "Shared Infrastructure" in features list
- Both methods (simple and shared) in TradingClient creation section
- New example in examples summary table
- Add `shared_infrastructure` to workspace members
