- 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
- Always derive bonding curve and associated bonding vault from mint (avoids stale cached PDAs / wrong pool).
- Use non-default fee_recipient from parser/stream as account #2 without extra authorization filtering (addresses Pump 6000 NotAuthorized when event fee was rejected).
- Rework resolve_creator_vault_for_ix: default-creator cases, phantom default PDA, fee-sharing vault; add unit tests.
- PumpFunParams: respect explicit mayhem_mode from events; fallback creator_vault via get_creator_vault_pda when resolve returns None.
- Remove unused lazy_static tip-cache stub and lazy_static dependency.
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 SWQOS_ENDPOINTS_BLOCKRAZOR_GRPC with correct gRPC endpoints
- Add Grpc variant to SwqosTransport enum
- Add get_endpoint_with_transport() method for transport-aware endpoint selection
- Change BlockRazor default: transport=None now uses gRPC (was HTTP)
- Require explicit Some(SwqosTransport::Http) for HTTP fallback
This fixes the issue where BlockRazor was incorrectly using HTTP endpoints
when gRPC was intended. Users can now use gRPC by default or explicitly
specify HTTP transport when needed.

Major changes:
- Switch BlockRazor default transport from gRPC to HTTP to avoid FRAME_SIZE_ERROR
- gRPC mode still available via explicit SwqosTransport configuration
- Fix ZeroSlot Binary-Tx JSON-RPC 2.0 response parsing
- Properly handle success responses with "result" field
- Properly handle error responses with "error" field containing code and message
- Update version to 4.0.0
- Update README files to reflect new version
Technical details:
- BlockRazor: HTTP mode is now the default (SwqosTransport::Http or None)
- ZeroSlot: Parse JSON-RPC 2.0 format responses instead of plain text
- Proto code: Pre-generated gRPC code for BlockRazor (no protoc required)

- Add BlockRazorBackend enum to support both gRPC and HTTP transport
- Default to gRPC for better performance, HTTP available via explicit selection
- Update SwqosConfig::BlockRazor to accept optional SwqosTransport parameter
- Implement keep-alive ping task for both gRPC and HTTP backends
- Follow same backend pattern as Astralane (Quic/Http) and Node1 (Quic/Http)
- Manual gRPC client implementation to avoid proto compilation issues
Usage:
- Default: BlockRazorClient::new() uses gRPC
- HTTP: BlockRazorClient::new_http() for HTTP transport
- Config: SwqosConfig::BlockRazor(token, region, url, None) for gRPC
- Config: SwqosConfig::BlockRazor(token, region, url, Some(Http)) for HTTP

- Rename wait_transaction_confirmed to wait_tx_confirmed (params, lib, docs, examples)
- SDK timing: use [SDK][provider] style with fixed-width labels; add newline before block
- Move print_sdk_timing_block to common::sdk_log; unify SWQOS_LABEL_WIDTH
- SWQOS submitted/failed: aligned [Provider] labels via log_swqos_submitted/submission_failed
- Extract short error message from JSON (message/data) or quoted string; prefix with 'error: '
- Format elapsed as 'X.XXXX ms' or 'X.XXXX µs' (4 decimals, space before unit); use comma before error
- Add SwqosType::as_str() for zero-allocation log labels; only parse JSON when input starts with '{'
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
