Add positions-owned endpoint to list all positions for a wallet in a pool.
Rename IDL file from amm_v3.json to clmm.json for clarity.
Add comprehensive README documenting implemented and pending routes.

Implemented routes:
- GET /pool-info (existing)
- GET /position-info (existing)
- GET /positions-owned (new)

The connector uses manual buffer decoding for read operations.
Transaction routes (openPosition, closePosition, etc.) are documented
as pending implementation due to complexity of instruction building
without a dedicated PancakeSwap SDK.

Add simplified quote-swap endpoint that uses current pool price.

Limitations:
- Uses spot price from pool state
- Does NOT calculate price impact across ticks
- Does NOT use tick array data for precise calculations
- Does NOT account for liquidity depth

This provides basic swap quoting without requiring complex
concentrated liquidity math or SDK dependencies.

Tested with SOL/USDC pool successfully.

Implement manual transaction building for swap_v2 instruction using
Anchor's BorshCoder to encode instruction data.

Key implementation:
- Manual pool data parsing to extract vaults and observation state
- Anchor instruction encoding without full Program client
- Support for both SPL Token and Token2022 programs
- Compute budget and priority fee handling
- Transaction simulation before sending

Features:
- POST /execute-swap endpoint for executing swaps
- Supports both BUY and SELL sides
- Configurable slippage protection
- Returns transaction signature and balance changes

Technical approach:
- Decodes pool account data to get required accounts

…PancakeSwap Solana

Added three position management routes:

1. **removeLiquidity**: Remove liquidity from existing positions by percentage
   - Takes percentageToRemove (0-100) parameter
   - Uses decrease_liquidity_v2 instruction with manual buffer decoding
   - Extracts position data to calculate tick arrays and protocol PDAs
   - Returns balance changes extracted from transaction

2. **closePosition**: Close empty positions
   - Validates position has zero liquidity before closing
   - Uses close_position instruction
   - Refunds position NFT account rent

3. **collectFees**: Collect accumulated fees
   - Uses clever Raydium approach: removes 1% liquidity to collect fees
   - Calls removeLiquidity internally with 1% parameter

Key implementation details:
- Added tick array address calculation (60 ticks per array)
- Added position data parsing to extract poolId, ticks, and liquidity
- Added pool tick spacing parsing
- Uses Token2022 for position NFTs with SPL Token fallback
- Proper response schema compliance with TransactionStatus enum

Fixed two issues in getPositionInfo:
1. Added null check for token info before accessing decimals property
   - Prevents "Cannot read properties of null" error when token not found
   - Returns null gracefully if tokens can't be loaded

2. Convert fee amounts to decimal format using token decimals
   - baseFeeAmount: Number(tokenFeesOwed0) / 10^baseDecimals
   - quoteFeeAmount: Number(tokenFeesOwed1) / 10^quoteDecimals
   - Previously showed raw amounts (e.g. 50109 instead of 0.050109)

This fixes the error seen in positions-owned route when iterating through
positions where some tokens may not be in the token list.

…tion

Enhanced quoteSwap to use actual pool data for realistic quotes:

**Price Impact Calculation**:
- Estimates impact based on swap amount vs pool token balances
- Impact ratio: (swapAmount / poolBalance) * 100%
- Price adjusts against trader: SELL lowers price, BUY raises price
- Uses pool liquidity concentration for more accurate estimates

**Fee Integration**:
- Uses actual pool fee from AMM config (poolInfo.feePct)
- SELL: Deducts fee from output amount
- BUY: Increases required input to cover fee
- Fee shown in response and logs

**Execution Price**:
- Spot price: Current pool price from sqrtPriceX64
- Execution price: Adjusted for estimated price impact
- Effective price: Final price including fees and impact
- Returned as amountOut/amountIn or amountIn/amountOut

**Example Results** (SOL/USDC pool):
- 0.01 SOL: ~0.0008% impact, price ≈ spot
- 1 SOL: ~0.08% impact, slight price movement
- 100 SOL: ~8% impact, significant slippage
- 10000 SOL: ~800% impact, would drain pool

**Limitations**:
- Impact estimation is simplified (linear approximation)
- Does not use tick-by-tick liquidity distribution
- May underestimate for very large cross-tick swaps
- Suitable for most practical swap sizes

**Improvements over previous**:
- ✅ Now uses actual pool fee (was 0%)
- ✅ Calculates price impact (was always 0%)
- ✅ Adjusts execution price (was spot price only)
- ✅ More realistic quotes for large swaps
- ✅ Better logging with impact and fee info

Upgraded @coral-xyz/anchor from 0.29.0 to 0.30.1 to fix BorshCoder error:
"Type not found: InitializeRewardParam"

**Issue**:
The PancakeSwap CLMM IDL uses Anchor 0.30+ format for defined types:
```json
{ "type": { "defined": { "name": "InitializeRewardParam" } } }
```

Anchor 0.29 uses the old format:
```json
{ "type": { "defined": "InitializeRewardParam" } }
```

**Fix**:
- Upgraded to Anchor 0.30.1 (supports new IDL format)
- BorshCoder can now properly parse all type definitions
- All swap instructions (swap_v2, open_position, etc.) now work

**Affected instructions using defined types**:
- initialize_reward (InitializeRewardParam)
- PoolState (Observation arrays)
- PersonalPositionState (PositionRewardInfo arrays)
- RewardInfo arrays
- TickArrayState (TickState arrays)

This fixes execute-swap errors when encoding instructions.

Fixed "AccountNotInitialized" error by properly handling token accounts:

**Token Account Setup** (pancakeswap-sol-utils.ts:150-200):
- Check if input/output token accounts exist before swap
- Create associated token accounts if they don't exist
- Prevents "account not initialized" errors

**WSOL Wrapping for Native SOL** (pancakeswap-sol-utils.ts:175-187):
When swapping from SOL:
1. Create WSOL associated token account
2. Transfer SOL lamports to WSOL account
3. Call syncNative to wrap SOL → WSOL
4. Close WSOL account after swap to recover remaining SOL

**Transaction Flow**:
```
1. Compute budget instructions
2. Create input ATA (if needed)
3. Wrap SOL to WSOL (if SOL input)
4. Create output ATA (if needed)
5. Execute swap instruction
6. Close WSOL account (if created)
```

**Imports Added**:
- NATIVE_MINT - Native SOL mint address
- createAssociatedTokenAccountInstruction
- createSyncNativeInstruction
- createCloseAccountInstruction

**Error Fixed**:
```
Before: AnchorError: AccountNotInitialized (3012)
After: Automatic ATA creation + WSOL wrapping
```

This enables SOL ↔ Token swaps without pre-created token accounts.

- Add getTokenProgramForMint() helper to detect if mint uses Token2022
- Update buildSwapV2Instruction to detect and use correct token programs
- Update buildSwapTransaction to use detected programs for ATA creation
- Use correct program for SyncNative and CloseAccount instructions
- This fixes potential swap failures when tokens use different programs

- Wrap SOL to WSOL before every swap when input is native SOL
- Don't close WSOL account after swap (keep it for future use)
- Add debug logging for pool tokens, vaults, and account addresses

- Add proper typing for catch blocks (e: any)
- Re-throw httpErrors with original statusCode instead of converting to 500
- Include error message in internal server errors
- Add descriptive error context logging
- Apply pattern across all 11 CLMM routes

- Add MIN_SQRT_PRICE_X64 and MAX_SQRT_PRICE_X64 constants
- Use MIN limit when isBaseInput=true (token0 -> token1)
- Use MAX limit when isBaseInput=false (token1 -> token0)
- Setting sqrtPriceLimitX64 to 0 was causing program panic

- Log all swap_v2 instruction details before execution
- Show instruction data hex, amount, threshold, price limit
- Display account count and isBaseInput flag
- Help diagnose Option::unwrap() panic at swap.rs:182:64

- Read tick_current and tick_spacing from pool state
- Calculate tick array start index for current tick
- Derive tick array PDA address
- Include tick array as 14th account (remaining account)
- Program needs tick array to traverse liquidity, was panicking without it
- Add tick info to debug logging

CRITICAL FIX: Anchor's BorshCoder requires exact IDL parameter names
- Changed otherAmountThreshold -> other_amount_threshold
- Changed sqrtPriceLimitX64 -> sqrt_price_limit_x64
- Changed isBaseInput -> is_base_input
- Previous camelCase names caused parameters to encode as 0
- This was causing the Option::unwrap() panic in swap.rs

- Remove MIN/MAX_SQRT_PRICE_X64 constants (values were causing overflow)
- Set sqrtPriceLimitX64 to 0 to indicate no price limit
- Slippage protection is handled by otherAmountThreshold
- Previous attempt with 0 failed due to parameter encoding bug (now fixed)

- Check if calculated tick array account exists before including it
- Program panics when trying to load non-existent tick array account
- Log warning when tick array is not initialized
- TODO: Implement proper tick array discovery for swap path

Fixed critical PDA derivation issues by switching from little-endian to
big-endian encoding for i32 seed values. Anchor programs use big-endian
encoding for integer seeds in PDA derivation.

Changes:
- Protocol position PDA: use BE for tick_lower and tick_upper indices
- Tick array PDA: use BE for start_index
- Applied fix to all affected functions:
  - buildOpenPositionWithToken22NftInstruction
  - buildDecreaseLiquidityV2Instruction
  - buildIncreaseLiquidityV2Instruction
  - getTickArrayAddress (used by swap and all CLMM operations)

Added comprehensive logging to openPosition route for debugging:
- Pool and token information
- Token program detection (SPL vs Token2022)
- Token account addresses
- Tick indices and spacing
- Tick array start indices and addresses
- PDA addresses (protocol position, personal position)
- Amount parameters and base flag
- Instruction data in hex

Also improved token program detection to support Token2022 mints
across all liquidity operations.

The addLiquidity route was failing with PriceSlippageCheck error (6021)
because it wasn't applying any slippage buffer to the token amounts.

Changes:
- Added slippagePct parameter to addLiquidity function
- Apply slippage buffer to amounts (same pattern as openPosition):
  amount = baseAmount * (1 + slippagePct / 100)
- Added logging to show slippage-adjusted amounts
- Schema already had slippagePct field, just needed to wire it up

The slippagePct parameter is treated as a percentage (e.g., 50 = 50%),
matching the behavior in openPosition.

This fixes the issue where adding liquidity would fail even with
sufficient slippage tolerance specified in the request.

Changed addLiquidity to follow Raydium's approach by calling quotePosition
to calculate proper token amounts based on the position's tick range and
current pool price, rather than directly using user-provided amounts.

This fixes the PriceSlippageCheck error by ensuring the amounts are
calculated correctly for the position's price range:
- Calls quotePosition with position's lowerPrice, upperPrice, and poolAddress
- Uses quote.baseTokenAmountMax and quote.quoteTokenAmountMax
- Applies slippage buffer on top of quoted max amounts
- Uses quote.baseLimited to determine baseFlag

This matches how Raydium CLMM handles addLiquidity and ensures proper
token ratio based on where the current price is relative to the position's
tick range.

vault addresses from the pool's reward system. Previous implementation only
had 16 accounts.

Changes:

Fixes AccountNotInitialized (3012) error when removing liquidity.

The decrease_liquidity_v2 instruction requires additional accounts for
active rewards. Each active reward (reward_state != 0) needs 3 accounts:
reward vault, user's ATA for reward token, and reward token mint.

Previous fix incorrectly added all 3 reward vaults directly. This caused
AccountNotInitialized errors for inactive rewards (which have System
Program as vault address).

Changes:
- Parse reward_state from pool's reward_infos array (offset 397)
- Only process active rewards (reward_state != 0)
- For each active reward, extract token_mint (offset +57) and token_vault (offset +89)
- Dynamically add 3 accounts per active reward: vault, user ATA, mint
- Detect correct token program for each reward mint

  - getAmountsFromLiquidity: Calculate amounts from liquidity
  - getLiquidityFromSingleAmount: Calculate from one token amount
  - Based on Uniswap V3/CLMM mathematical formulas

Implement Solana RPC rate limit detection and proper HTTP 429 error responses:

**Rate Limit Interceptor (new file)**
- Create proxy-based Connection wrapper to intercept all RPC methods
- Detect 429 errors from multiple sources: statusCode, code, message patterns
- Transform rate limit errors into actionable user messages with:
  - Current RPC URL causing the limit
  - Network-specific config file path (mainnet-beta.yml vs devnet.yml)
  - Instructions to update nodeURL or configure Helius

**Error Propagation**
- Add re-throw logic for 429 errors in:
  - getSolBalance and fetchTokenAccounts (balances route)
  - confirmTransaction (both getTransaction and getSignatureStatus)
  - _sendAndConfirmRawTransaction (polling loop, re-broadcast, getBlockHeight)
- Non-429 errors continue graceful handling (return 0 for balances, retry for transient errors)

**Bug Fixes**
- Fix confirmTransaction promise executor to properly propagate errors
- Add 429 re-throw in outer try-catch of _sendAndConfirmRawTransaction

**Chain-Level Swap Schemas**
- Create ChainQuoteSwapResponseSchema without quoteId (quotes not cached at chain level)
- Create ChainExecuteSwapResponseSchema for standardized swap execution responses
- Update Solana and Ethereum quote-swap routes to use new schemas

**Comprehensive Test Coverage (40 tests)**
- Interceptor tests: 429 detection patterns, error messages, method coverage
- Propagation tests: Error flow through Solana class methods
- Route tests: HTTP 429 responses, actionable error messages

Created test infrastructure to reduce duplication across chain route tests:

**New Helpers:**
- test/helpers/commonMocks.ts: Centralized logger & ConfigManagerV2 mocks
- test/helpers/connectorMocks.ts: createRouteMock() for connector mocks
- test/helpers/mockResponses.ts: Factory functions for mock responses
- test/constants/mockTokens.ts: Centralized token addresses & constants

**Improvements:**
- Reduced logger mock duplication by 89% (72 lines → 8 lines)
- Reduced ConfigManagerV2 mock duplication by 89%
- Reduced connector mock boilerplate by 75% (using require() in jest.mock)
- Replaced 20+ hardcoded wallet addresses with MOCK_WALLET_ADDRESSES
- Eliminated duplicate mock response objects with factory functions

**Key Pattern:**
Used require() inside jest.mock() factory functions to call helpers while
satisfying Jest's hoisting requirements:
```typescript
jest.mock('path', () => require('helpers').createRouteMock('executeSwap'));
```

**Files Refactored:**
- test/chains/ethereum/routes/execute-swap.test.ts
- test/chains/ethereum/routes/quote-swap.test.ts
- test/chains/solana/routes/execute-swap.test.ts
- test/chains/solana/routes/quote-swap.test.ts

Fixed failing universal router tests to reflect the new behavior where
gas estimation is skipped during quote phase and deferred to execution:

**Test Updates:**
- test/connectors/uniswap/universal-router.test.ts: Updated expectation
  from 500000 to 0 for estimatedGasUsed during quote phase
- test/connectors/pancakeswap/universal-router.test.ts: Updated expectation
  from 500000 to 0 for estimatedGasUsed during quote phase

**Implementation Update:**
- src/connectors/pancakeswap/universal-router.ts: Aligned with Uniswap
  implementation to skip gas estimation during quote phase for consistency

**Rationale:**
Gas estimation during quote phase was intentionally removed in commit
99f4022 to improve performance. Quote phase now returns estimatedGasUsed=0
as a placeholder, with actual estimation happening during execution phase.

**Test Status:**
- Uniswap universal router: ✅ All tests passing

Add unified /swap/quote and /swap/execute routes that accept chain-network parameter (e.g., "solana-mainnet-beta", "ethereum-mainnet") to enable cross-chain swap routing from a single endpoint.

Changes:
- Add src/routes/swap/quote.ts: GET /swap/quote endpoint with chain-network routing
- Add src/routes/swap/execute.ts: POST /swap/execute endpoint with chain-network routing
- Update src/app.ts: Register unified swap routes before chain-specific routes
- Implement parseChainNetwork() utility to parse "chain-network" format
- Route to appropriate chain implementation (Ethereum/EVM or Solana) based on chain parameter
- Support all EVM chains (ethereum, arbitrum, avalanche, base, bsc, celo, optimism, polygon, sepolia)

Fix chain-network parameter format to properly route EVM networks:
- Use "ethereum-polygon" not "polygon-mainnet"
- Use "ethereum-mainnet", "ethereum-arbitrum", etc.
- Only "ethereum" and "solana" as chain identifiers in switch statement
- Networks like polygon, arbitrum, base are passed as network parameter to Ethereum handler

Changes:
- Remove individual EVM chain cases from switch statements
- Update documentation and examples to show correct format
- Verified with manual testing: ethereum-polygon, ethereum-mainnet, solana-mainnet-beta

Major Changes:
- Moved swap logic from chain-specific routes to unified /trading/swap endpoints
- Removed poolAddress parameter from all positions-owned endpoints
- Added connector parameter support to swap quote and execute endpoints
- Fixed Meteora SDK bug handling with proper error responses

Swap Routes Refactoring:
- Deleted src/chains/{ethereum,solana}/routes/{execute,quote}-swap.ts
- Moved all logic into src/trading/swap/{execute,quote}.ts
- Created src/trading/trading.routes.ts for route registration
- Updated src/app.ts to register trading routes at /trading/swap prefix
- Routes now handle both Ethereum and Solana chains in single endpoint

Positions-Owned Refactoring:
- Updated Meteora, PancakeSwap-Sol, and Raydium positions-owned endpoints
- Removed poolAddress from request schemas (now fetch ALL positions)
- Updated implementations to return all positions across all pools
- Added comprehensive tests for all three connectors

Meteora Fixes:
- Added error handling for SDK bug in getAllLbPairPositionsByUser
- Returns 503 Service Unavailable with descriptive error message
- Fixed price decimal adjustment in quotePosition endpoint
- Set fee amounts to 0 for batch position fetching (SDK limitation)
- Filed GitHub issue: MeteoraAg/dlmm-sdk#245

Test Fixes:
- Fixed Raydium test with valid Solana public keys
- Fixed Solana RPC provider test to accept both 'url' and 'helius'
- Fixed PancakeSwap-Sol test to handle closed positions gracefully
- All 569 tests now passing (2 skipped)

Enhancements to unified swap routes for better developer experience:

Schema Improvements:
- Add default values to all parameters for Swagger UI auto-population
- Reorder parameters: walletAddress first in execute, connector second in both
- Change side from Type.Union to Type.String with enum for proper dropdown in Swagger
- Use Jupiter/router as default connector example (SOL/USDC swap)

Dynamic Configuration:
- Fetch defaultWallet from Solana chain config at runtime
- Fallback to Ethereum chain config if Solana not configured
- Replace hardcoded wallet address with dynamic config value

Technical Fixes:
- Add type assertions (as 'BUY' | 'SELL') for side parameter to satisfy TypeScript
- Import getSolanaChainConfig and getEthereumChainConfig functions
- Ensure build passes with proper type safety

Swagger UI Defaults:
- chainNetwork: solana-mainnet-beta
- connector: jupiter/router
- walletAddress: <from config>
- baseToken: SOL
- quoteToken: USDC
- amount: 1
- side: SELL (dropdown shows BUY/SELL)
- slippagePct: 1

- Extract business logic from Uniswap and PancakeSwap CLMM routes into reusable functions
- Extract business logic from Raydium, Meteora, and PancakeSwap-Sol CLMM routes
- Create unified transaction routes at /trading/clmm/* for cross-chain operations:
  - POST /trading/clmm/open - Open new CLMM position
  - POST /trading/clmm/add - Add liquidity to existing position
  - POST /trading/clmm/remove - Remove liquidity from position
  - POST /trading/clmm/collect-fees - Collect accumulated fees
  - POST /trading/clmm/close - Close position completely
- Change /pools/{poolAddress} to /pool-info with query parameter
- Change /positions/{positionAddress} to /position-info with query parameter
- Add comprehensive test coverage for unified CLMM routes
- Fix pancakeswap-sol positionsOwned tests to properly mock Token2022 calls

All connectors (uniswap, pancakeswap, raydium, meteora, pancakeswap-sol) now support
unified routing through /trading/clmm/* endpoints with consistent request/response schemas.
