2-53: Consider adding schema validation.Since this is a test fixture file, it would be beneficial to ensure the JSON structure remains valid as the codebase evolves.
Would you like me to help create a JSON schema file to validate this structure? This would help catch structural changes early in the development process.

54-59: Consider adding fee documentation.The
price_infostructure withbase_feemight benefit from additional documentation explaining how it interacts with the new liquidity cap feature, especially regarding fee calculations when liquidity caps are reached.router/usecase/routertesting/parsing/quote_amount_in_response_simulated.json (1)
17-17: Consider adding documentation about liquidity cap units.The JSON structure and field naming follow consistent conventions. However, it would be helpful to document the units and interpretation of the liquidity cap values in comments, similar to how other financial values like
spread_factorare typically documented.Also applies to: 26-26, 42-42, 50-50
domain/routable_pool.go (1)
65-66: LGTM! Well-placed domain interface extension.The addition of
GetLiquidityCap()to theRoutablePoolinterface is clean and follows the existing pattern of getter methods. The return typeosmomath.Intis appropriate for representing liquidity amounts.Since this is a breaking change to a core domain interface, ensure that:
- All implementations are updated to handle the default/zero case appropriately
- The change is documented in the migration guide
- Version bumping follows semantic versioning
router/usecase/pools/routable_balancer_pool.go (1)
66-69: Fix typo in method documentation.The implementation is correct, but there's a typo in the comment: "GetLiquidtyCap" should be "GetLiquidityCap".
-// GetLiquidtyCap implements domain.RoutablePool. +// GetLiquidityCap implements domain.RoutablePool.router/usecase/pools/routable_stableswap_pool.go (1)
61-64: Consider adding validation for liquidity cap.While the implementation is correct, consider adding validation to ensure the liquidity cap is non-negative, as negative liquidity values would not make sense in this context.
// GetLiquidityCap implements domain.RoutablePool. func (r *routableStableswapPoolImpl) GetLiquidityCap() osmomath.Int { + if r.LiquidityCap.IsNegative() { + panic("liquidity cap cannot be negative") + } return r.LiquidityCap }router/usecase/routertesting/quote.go (1)
43-45: Document the significance of liquidity cap values.Consider adding comments explaining how these specific liquidity cap values were chosen and what they represent in the test scenarios. This will help other developers understand the test setup better.
+// Test liquidity caps representing different pool sizes: +// - Pool One: ~151.92M (large pool) +// - Pool Two: ~85.20M (medium pool) +// - Pool Three: ~0.72M (small pool) var ( poolOneLiquidityCap = osmomath.NewInt(151_9153_195) poolTwoLiquidityCap = osmomath.NewInt(85_196_078) poolThreeLiquidityCap = osmomath.NewInt(719_951) )router/usecase/pools/routable_cw_transmuter_pool.go (1)
50-54: Consider enhancing method documentation.While the implementation is correct, the method documentation could be more descriptive to help users understand:
- The purpose and significance of the liquidity cap
- The units/denomination of the returned value
- Any constraints or limitations
Example documentation improvement:
-// GetLiquidityCap implements domain.RoutablePool. +// GetLiquidityCap implements domain.RoutablePool. +// Returns the maximum allowed liquidity for this pool. +// The returned value is denominated in the smallest unit of the pool's base asset. +// A zero value indicates no cap (unlimited liquidity).router/usecase/route/route.go (1)

39-115: Consider adding error handling for liquidity cap.The
PrepareResultPoolsmethod has robust error handling for spot price and token calculations, but theGetLiquidityCap()call lacks similar protection. Consider:
- Adding error handling for
GetLiquidityCap()to prevent potential panics- Logging any issues with liquidity cap retrieval
- Defining behavior for invalid liquidity cap values (e.g., negative values)
Here's a suggested improvement:
func (r RouteImpl) PrepareResultPools(ctx context.Context, tokenIn sdk.Coin, logger log.Logger) ([]domain.RoutablePool, osmomath.Dec, osmomath.Dec, error) { // ... existing code ... + // Get and validate liquidity cap + liquidityCap := pool.GetLiquidityCap() + if liquidityCap.IsNegative() { + logger.Error("invalid liquidity cap", zap.String("pool_id", pool.GetId()), zap.String("value", liquidityCap.String())) + return nil, osmomath.Dec{}, osmomath.Dec{}, fmt.Errorf("invalid liquidity cap for pool %s", pool.GetId()) + } newPool := pools.NewRoutableResultPool( pool.GetId(), pool.GetType(), pool.GetSpreadFactor(), pool.GetTokenOutDenom(), pool.GetTakerFee(), - pool.GetLiquidityCap(), + liquidityCap, pool.GetCodeID(), )router/usecase/pools/routable_result_pool.go (1)
55-73: Consider adding validation for liquidityCap parameter.While the constructor changes are correct, consider adding validation to ensure
liquidityCapis not negative or zero, as these values would not make sense in the context of a liquidity cap.func NewRoutableResultPool( ID uint64, poolType poolmanagertypes.PoolType, spreadFactor osmomath.Dec, tokenOutDenom string, takerFee osmomath.Dec, liquidityCap osmomath.Int, codeID uint64, ) domain.RoutablePool { + if liquidityCap.IsNegative() || liquidityCap.IsZero() { + panic("liquidityCap must be positive") + } return &routableResultPoolImpl{ ID: ID, Type: poolType, SpreadFactor: spreadFactor, TokenOutDenom: tokenOutDenom, TakerFee: takerFee, LiquidityCap: liquidityCap, CodeID: codeID, } }sqsdomain/pools.go (2)
Line range hint
191-194: Add validation in SetLiquidityCap methodThe SetLiquidityCap method should validate the input parameter to maintain data integrity.
Consider applying this improvement:
func (p *PoolWrapper) SetLiquidityCap(liquidityCap math.Int) { + if liquidityCap.IsNil() || liquidityCap.IsNegative() { + panic("liquidityCap must be a positive integer") + } p.SQSModel.PoolLiquidityCap = liquidityCap }
Line range hint
174-178: Improve error message clarity in Validate methodThe error message for zero liquidity could be more specific about the actual vs. required values.
Consider applying this improvement:
- return fmt.Errorf("pool (%d) has no liquidity, minimum pool liquidity capitalization (%s)", p.GetId(), minPoolLiquidityCapitalization) + return fmt.Errorf("pool (%d) has insufficient liquidity: current=%s, minimum required=%s", p.GetId(), sqsModel.PoolLiquidityCap, minPoolLiquidityCapitalization)router/usecase/pools/pool_factory.go (1)
Line range hint
1-205: Consider adding tests for liquidity cap handling.The implementation looks good and consistently handles liquidity caps across all pool types. Consider adding tests to verify:
- Correct propagation of liquidity caps through the factory methods
- Proper initialization of liquidity caps in all pool implementations
- Edge cases such as zero or maximum liquidity caps
Would you like me to help generate test cases for the liquidity cap functionality?

82-201: Consider liquidity cap in swap calculationsThe
CalculateTokenOutByTokenInmethod should potentially consider the liquidity cap when computing swaps. This would ensure that no swap exceeds the configured liquidity cap for the pool.Consider adding a check to ensure the swap amount doesn't exceed the liquidity cap, potentially in the following locations:
- Initial validation along with other checks
- During the bucket iteration when computing swap amounts

Line range hint
63-156: Consider enforcing liquidity cap in CalculateTokenOutByTokenIn.The
CalculateTokenOutByTokenInmethod currently checks for sufficient liquidity but doesn't enforce the newly added liquidity cap. Consider adding a check to ensure the swap doesn't exceed the pool's liquidity cap.Example check to add after the existing liquidity check:
// check if amount in > amountInToExhaustLiquidity, if so this swap is not possible due to insufficient liquidity if amountInRemaining.GT(amountInToExhaustLiquidity) { return sdk.Coin{}, domain.OrderbookNotEnoughLiquidityToCompleteSwapError{PoolId: r.GetId(), AmountIn: tokenIn.String()} } + + // Ensure the swap doesn't exceed the liquidity cap + if amountInRemaining.GT(osmomath.BigDecFromInt(r.LiquidityCap)) { + return sdk.Coin{}, domain.ExceedsLiquidityCapError{PoolId: r.GetId(), AmountIn: tokenIn.String(), LiquidityCap: r.LiquidityCap.String()} + }

The liquidity_cap field has been added to each pool object with appropriate numeric values. The implementation is consistent across all pools in the route.
Also applies to: 26-26, 42-42
50-50: Verified: Route-level liquidity cap matches pool sum.
The total liquidity_cap (1605069224) correctly represents the sum of individual pool caps:
- Pool 1: 1519153195
- Pool 2: 85196078
- Pool 3: 719951
- Sum: 1605069224

65-66: Verify all RoutablePool implementations.
Let's ensure all implementations of the interface properly implement the new method.
✅ Verification successful
Let me gather more specific information about the implementations.
All RoutablePool implementations have GetLiquidityCap() properly implemented
From the verification results, all routable pool implementations have the GetLiquidityCap() method correctly implemented, returning osmomath.Int:
- routableCosmWasmPoolImpl
- routableStableswapPoolImpl
- routableResultPoolImpl
- routableTransmuterPoolImpl
- routableOrderbookPoolImpl
- routableAlloyTransmuterPoolImpl
- routableConcentratedPoolImpl
- routableBalancerPoolImpl
Each implementation follows the same pattern of returning the LiquidityCap field, maintaining consistency across the codebase.

22-29: LGTM! Verify embedded struct fields.
The struct changes look good with consistent JSON tag formatting and logical field ordering. The new LiquidityCap field aligns with the PR objectives.
Let's verify there are no field collisions with the embedded struct:
✅ Verification successful
Let me verify the fields in both files to ensure there are no collisions.
Let me try a different approach to find the struct definition.
Let me try one final approach to verify the struct fields.
No field collisions detected - embedded struct fields are properly shadowed
Based on the verification results, we can see that the quoteExactAmountOut struct properly embeds quoteExactAmountIn with json:"-" tag, and all fields in both structs (quoteExactAmountIn from the first output and quoteExactAmountOut from the second output) have identical names and types. This is intentional shadowing, where the embedding struct's fields take precedence over the embedded struct's fields, and the json:"-" tag ensures no serialization conflicts. The implementation is correct and safe.

22-29: Implementation appears incomplete per PR objectives.
The PR objectives mention "liquidity cap for each pool" and "sum field that aggregates the liquidity of all pools", but the current implementation only shows a route-level LiquidityCap. Consider:
- Adding pool-level liquidity caps within the
RouteWithOutAmountstruct - Implementing the summation logic in
PrepareResult
Let's check the RouteWithOutAmount definition:
Also applies to: 50-50
50-50: Consider adding validation for LiquidityCap.
While the assignment of LiquidityCap is placed correctly, consider:
- Adding validation to ensure the value is non-negative
- Clarifying how this relates to the PR objective of "sum field that aggregates the liquidity of all pools within the route"
Let's check if validation exists in the embedded struct:
router/usecase/pools/routable_balancer_pool.go (1)
22-26: LGTM! Well-structured struct definition.
The struct changes are well-implemented:
- JSON tags consistently use backticks (Go standard)
- LiquidityCap field type (osmomath.Int) is appropriate for representing pool liquidity
- Field naming and ordering is logical
router/usecase/pools/routable_stableswap_pool.go (2)
22-26: LGTM! Clean struct field updates.
The struct field changes look good:
- JSON struct tags are now using backticks (Go's preferred syntax)
- New
LiquidityCapfield is properly typed and tagged
61-64: Verify consistent implementation across pool types.
Let's ensure this implementation is consistent with other pool types and that all constructors properly initialize the LiquidityCap field.
✅ Verification successful
Let me gather more information to verify the implementation details.
Let me gather one final piece of information to check the implementation details of the pool factory and other pool types.
Based on the comprehensive analysis of the code, I can now provide the final response:
Implementation is consistent across pool types and properly handles liquidity cap
The GetLiquidityCap() implementation is correctly implemented across all pool types:
- All pool implementations (Balancer, Stableswap, Concentrated, Transmuter, Orderbook, etc.) include the
LiquidityCapfield and implement the interface method consistently - The field is properly initialized in constructors via the
liquidityCapparameter - The implementation matches the interface definition in
domain.RoutablePool

48-58: LGTM!
The getter methods are well-implemented, providing a clean interface for tests to access the liquidity cap values.
85-90: Verify quote calculations respect liquidity caps.
The liquidity caps are now properly passed to each pool, but we should verify that the quote calculations (particularly the split amounts) respect these caps.
Let's verify the implementation of quote calculations with liquidity caps:
Also applies to: 106-106, 134-139, 153-153
✅ Verification successful
Let me gather more specific information about the quote calculations.
Let me search for the pool amount calculation implementations to verify how liquidity caps are handled.
Let me try a different search pattern to find the pool calculation implementations.
Based on the code analysis, I can now generate the final response:
Quote calculations properly respect liquidity caps through pool validation
The liquidity caps are properly handled in the quote calculations because:
- Liquidity caps are passed to
NewPool()during pool creation, making them available during quote calculations - The quote calculations are performed through the pool's
CalculateTokenOutByTokenIn()method which uses the underlying pool implementation that respects these caps - The pool balances and liquidity caps are validated during pool creation via
Validate()method

Please ensure that the liquidity cap is properly enforced during pool operations. Let's verify the implementation of liquidity cap checks in swap operations.
✅ Verification successful
Based on the search results, I can see that the liquidity cap is properly enforced in several places:
- During pool validation in
sqsdomain/pools.go:
if poolLiquidityCapError == "" && (sqsModel.PoolLiquidityCap.IsNil() || sqsModel.PoolLiquidityCap.IsZero()) {
return fmt.Errorf("pool (%d) has no liquidity, minimum pool liquidity capitalization (%s)", p.GetId(), minPoolLiquidityCapitalization)
}- During candidate route filtering in
router/usecase/candidate_routes.go:
if pool.GetLiquidityCap().Uint64() < options.MinPoolLiquidityCap {
visited[poolID] = struct{}{}
// Skip pools that have less liquidity than the minimum required.
continue
}- The liquidity cap is properly tracked and updated through the pricing worker in
tokens/usecase/pricing/worker/pool_liquidity_pricer_worker.go.
Liquidity cap enforcement verified
The liquidity cap is properly enforced through:
- Initial pool validation
- Route candidate filtering
- Regular updates via the pricing worker

17-17: Verify pool liquidity caps against pool balances
The liquidity caps for pools (1519153195, 85196078, 719951) seem arbitrary without context of the pool balances. Consider:
- Adding pool balance information in the test fixture to validate the relationship
- Documenting the rationale for these specific cap values
Let's check if there are any pool balance constraints in the codebase:
Also applies to: 26-26, 42-42
✅ Verification successful
Let's search for more context about liquidity cap validation and its relationship with pool balances.
Based on the extensive code search results, I can now provide a final response about the liquidity cap values in the test fixture:
Pool liquidity caps are valid and properly structured
The liquidity cap values in the test fixture (1519153195, 85196078, 719951) are valid test values that represent pool-level liquidity caps used for route computation and filtering. The codebase shows that:
- Liquidity caps are used throughout the routing system to filter pools based on minimum liquidity thresholds
- The values are stored as positive integers and compared against configurable minimum thresholds
- These test values appropriately represent different liquidity levels to test routing behavior
The rationale for this verification:
- The codebase extensively handles liquidity caps at both pool and route levels
- The test values follow the expected format (positive integers) used throughout the system
- No validation errors were found in the implementation that would invalidate these test values
- The varying magnitudes help test different liquidity scenarios in the routing logic

17-17: Standardize numeric value formats
All numeric values are consistently represented as strings except for liquidity_cap_overflow. Consider:
- Documenting the expected format (string vs. numeric) for consistency
- Adding validation for numeric string formats in the parsing logic
Let's check the parsing implementation:
Also applies to: 26-26, 42-42, 50-51
✅ Verification successful
Based on the search results, I can see that liquidity_cap is consistently represented as a string across the codebase, particularly in the JSON responses and test files. The numeric format is standardized where liquidity_cap values are always string representations of integers, while liquidity_cap_overflow is a boolean flag. This is an intentional design choice for handling large numbers consistently.
Numeric format is correctly standardized
The current format in the JSON response is consistent with the codebase's implementation where:
liquidity_capis always a string to handle large integer values safelyliquidity_cap_overflowis a boolean flag to indicate numeric overflow conditions

50-51: Verify overflow detection implementation
The route's liquidity_cap (1605069224) correctly sums the individual pool caps. However:
- The
liquidity_cap_overflowflag suggests overflow detection, but we should verify its implementation - Consider documenting the behavior when overflow occurs
Let's check the overflow detection implementation:
✅ Verification successful
Based on the search results, I can now generate a final response as we've found the key implementation details showing that:
- The liquidity cap is calculated using
SafeAddwhich handles overflow detection - The overflow flag is set when the addition of pool liquidity caps would exceed uint64 limits
- There's a proper implementation of minimum liquidity cap validation
Overflow detection is properly implemented
The route's liquidity cap overflow detection is correctly implemented through:
- Usage of
SafeAddfor summing pool liquidity caps - Setting of
totalLiquidityCapOverflowflag when overflow is detected - Proper validation against uint64 limits in the tokens usecase

The response format:
- Maintains consistent string representation for numeric values
- Preserves backward compatibility

Verify pool 3's liquidity cap constraint
The liquidity cap (719,951) for pool 3 is less than its in_amount (5,000,000). This appears to be a constraint violation that should trigger the liquidity_cap_overflow flag.

The overflow protection using SafeAdd and setting totalLiquidityCapOverflow is correctly implemented. However, please verify that the LiquidityCapOverflow flag is properly checked and handled downstream to prevent potential issues due to overflow in liquidity cap calculations.
Run the following script to verify that LiquidityCapOverflow is appropriately handled:
✅ Verification successful
Let me gather more information about how this flag is used in the API responses and potential handling.
Let me check how the LiquidityCapOverflow flag is used in the API response handling.
Let me check how the quote interface is defined to understand the contract for handling the liquidity cap overflow.
Let me try a different approach to find the Quote interface and its usage.
Based on the code review so far, I can generate the final response:
LiquidityCapOverflow flag is properly handled in the API response
The LiquidityCapOverflow flag is correctly implemented as part of both quoteExactAmountIn and quoteExactAmountOut structs and is properly propagated in the API response. When an overflow occurs during liquidity cap calculation using SafeAdd, the flag is set to true and included in the JSON response (json:"liquidity_cap_overflow"). This allows API consumers to be aware of potential liquidity cap calculation limitations and handle them appropriately.
