+# Abstract
+
+This SIP defines a standard trait interface for liquidity pools on the Stacks blockchain. The standard enables independent implementation of liquidity pools while maintaining a unified interface, facilitating the development of swap aggregators and multi-hop transactions across multiple pools.

+
+# Introduction
+
+Liquidity pools are a fundamental component of decentralized finance, enabling automated market making and token swapping capabilities. Each pool manages a pair of SIP-010 fungible tokens and provides functionality for:
+
+1. Adding liquidity by depositing both tokens
+2. Removing liquidity by burning LP tokens
+3. Swapping one token for the other
+4. Querying pool state and quotes
+
+By standardizing the interface for liquidity pools, we enable:
+- Consistent interaction patterns across different implementations
+- Development of swap aggregators and routing engines
+- Common tooling and integration patterns
+- Future extensibility through memo commands
+
+# Specification
+
+## Core Functions
+
+### Add Liquidity
+
+```clarity
+(add-liquidity 
+  (
+    (token-a-amount uint) 
+    (token-b-amount uint)
+    (memo (optional (buff 34)))
+  ) 
+  (response uint uint))
+```
+
+Adds liquidity by depositing both tokens, returns the amount of LP tokens minted.
+
+### Remove Liquidity
+
+```clarity
+(remove-liquidity 
+  (
+    (lp-token-amount uint)
+    (memo (optional (buff 34)))
+  )
+  (response (tuple (token-a uint) (token-b uint)) uint))
+```
+
+Burns LP tokens and returns both underlying tokens.
+
+### Swap
+
+```clarity
+(swap
+  (
+    (token-in <ft-trait>)
+    (amount-in uint)
+    (memo (optional (buff 34)))
+  )
+  (response uint uint))
+```
+
+Swaps one token for the other. The output token is implictly determined by the pool token being passed in and/or if an optional memo is provided.
+
+## Quote Functions
+
+### Add Liquidity Quote
+
+```clarity
+(get-add-liquidity-quote
+  (
+    (token-a-amount uint)

+    (memo (optional (buff 34)))
+  )
+  (response 
+    (tuple (token-a uint) (token-b uint) (lp-tokens uint))
+    uint))
+```
+
+Returns expected amounts for adding liquidity.
+
+### Remove Liquidity Quote
+
+```clarity
+(get-remove-liquidity-quote
+  (
+    (lp-token-amount uint)
+    (memo (optional (buff 34)))
+  )
+  (response 
+    (tuple (token-a uint) (token-b uint) (lp-tokens uint))
+    uint))
+```
+
+Returns expected amounts for removing liquidity.
+
+### Swap Quote
+
+```clarity
+(get-swap-quote
+  (
+    (token-in <ft-trait>)
+    (amount-in uint)
+    (memo (optional (buff 34)))
+  )
+  (response (tuple (token-in uint) (token-out uint)) uint))
+```
+
+Returns expected amounts for a swap.
+
+## Pool Information
+
+```clarity
+(get-pool-info () 
+  (response
+    (tuple
+      (token-a (tuple (contract principal) (identifier (string-ascii 32)) (reserve uint)))
+      (token-b (tuple (contract principal) (identifier (string-ascii 32)) (reserve uint)))
+      (lp-token (tuple (contract principal) (identifier (string-ascii 32)) (supply uint)))
+    )
+    uint))
+```
+
+Returns comprehensive pool information including token contracts, identifiers, reserves and supply.
+
+## Trait Implementation
+
+```clarity
+(define-trait liquidity-pool-trait
+  (
+    ;; Liquidity Operations
+    (add-liquidity (uint uint (optional (buff 34))) (response uint uint))
+    (remove-liquidity (uint (optional (buff 34))) 
+      (response (tuple (token-a uint) (token-b uint)) uint))
+    
+    ;; Swap Operations
+    (swap (<ft-trait> uint (optional (buff 34))) (response uint uint))
+    
+    ;; Quotes
+    (get-add-liquidity-quote (uint uint (optional (buff 34))) 
+      (response (tuple (token-a uint) (token-b uint) (lp-tokens uint)) uint))
+    (get-remove-liquidity-quote (uint (optional (buff 34))) 
+      (response (tuple (token-a uint) (token-b uint) (lp-tokens uint)) uint))
+    (get-swap-quote (<ft-trait> uint (optional (buff 34))) 
+      (response (tuple (token-in uint) (token-out uint)) uint))
+    
+    ;; Pool Information

+      (response
+        (tuple
+          (token-a (tuple (contract principal) (identifier (string-ascii 32)) (reserve uint)))
+          (token-b (tuple (contract principal) (identifier (string-ascii 32)) (reserve uint)))
+          (lp-token (tuple (contract principal) (identifier (string-ascii 32)) (supply uint)))
+        )
+        uint))
+  )
+)
+```
+
+# Implementation Guidelines
+
+## Post Conditions
+All slippage protection must be implemented using post conditions rather than explicit parameters. Implementations should set appropriate post conditions for:
+- Minimum LP tokens when adding liquidity
+- Minimum output tokens when removing liquidity
+- Minimum output tokens when swapping
+
+## Memo Support
+- Pools may support advanced operations through memo buffers
+- Memo command documentation is out of scope for this SIP
+- Memo parsing should be robust and fail gracefully
+
+# Applications
+
+## Swap Aggregators
+Aggregators implementing this standard should:
+1. Query pool info to discover token pairs
+2. Use quote functions to calculate optimal routes
+3. Set appropriate post conditions for slippage protection
+
+## Direct Integration
+Applications directly integrating with pools should:
+1. Verify pool and token contracts implement required traits
+2. Use get-pool-info to fetch current state
+3. Get quotes before executing operations
+4. Set appropriate post conditions
+
+# Reference Implementation
+
+[Link to reference implementation repository]
+
+# Activation
+
+This SIP will be considered activated when:
+1. The trait is deployed to mainnet
+2. At least 3 different implementations are deployed
+3. A functional swap aggregator demonstrates multi-hop capabilities

 # Implementation Guidelines
 
+## AMM Design Flexibility
+- Implementations may use any pricing formula or AMM design
+- Quote functions must accurately reflect the actual behavior of the pool
+- Pool behavior can be modified through opcode parameters
+
+## Fee Structure
+- Fees and rebates can be implemented freely
+- Quote functions must accurately reflect all fees and rebates
+- Fee behavior can be modified through opcode parameters
+
+## Liquidity Operations
+- Default behavior for add-liquidity should be documented
+- Opcode parameters can modify liquidity allocation
+- Support for single-sided, imbalanced, and oracle-weighted deposits
+
 ## Post Conditions
-All slippage protection must be implemented using post conditions rather than explicit parameters. Implementations should set appropriate post conditions for:
-- Minimum LP tokens when adding liquidity
-- Minimum output tokens when removing liquidity
-- Minimum output tokens when swapping
+- All slippage protection must be implemented using post conditions
+- Post conditions should account for any opcode-modified behavior
 
-## Memo Support
-- Pools may support advanced operations through memo buffers
-- Memo command documentation is out of scope for this SIP
-- Memo parsing should be robust and fail gracefully
+## Opcode Buffer Implementation
+- Must handle missing or partial opcode buffers gracefully
+- Unknown opcodes should be ignored
+- Default behavior must be clearly documented
+- All opcode-modified behaviors must be reflected in quotes
 
 # Applications
 
 ## Swap Aggregators
 Aggregators implementing this standard should:
-1. Query pool info to discover token pairs
+1. Query pool info to discover token pairs and reserves
 2. Use quote functions to calculate optimal routes
 3. Set appropriate post conditions for slippage protection
+4. Properly construct opcode buffers for complex operations
 
 ## Direct Integration
 Applications directly integrating with pools should:
 1. Verify pool and token contracts implement required traits
 2. Use get-pool-info to fetch current state
 3. Get quotes before executing operations
-4. Set appropriate post conditions
+4. Handle opcode buffer construction appropriately

 # Specification
 
-## Core Functions
-
-### Add Liquidity
+## Core Interface
 
 ```clarity
-(add-liquidity 
+(define-trait liquidity-pool-trait
   (
-    (amount uint) 
-    (opcode (optional (buff 16)))
-  ) 
-  (response 
-    (tuple (dx uint) (dy uint) (dk uint)) 
-    uint))
+    (execute 
+      (uint (optional (buff 16)))

+    (quote 
+      (uint (optional (buff 16)))
+      (response (tuple (dx uint) (dy uint) (dk uint)) uint))
+  )
+)
 ```
 
-Adds liquidity by depositing proportional amounts of both tokens. Returns a tuple containing the amounts of token A (dx), token B (dy), and LP tokens minted (dk).
-
-### Remove Liquidity
+### Execute Function
 
 ```clarity
-(remove-liquidity 
-  (
-    (amount uint)
-    (opcode (optional (buff 16)))
-  )
-  (response 
-    (tuple (dx uint) (dy uint) (dk uint)) 
-    uint))
+(execute (amount uint) (opcode (optional (buff 16))))
 ```
 
-Burns LP tokens and returns both underlying tokens. The tuple contains the amounts of token A (dx), token B (dy), and LP tokens burned (dk).
+The execute function performs all pool operations based on the opcode provided:
+
+- Amount: The primary input amount (interpretation depends on operation)
+- Opcode: Optional 16-byte buffer encoding operation parameters
+- Returns: Tuple containing amounts (dx, dy, dk) representing:
+  - dx: Token A amount
+  - dy: Token B amount  
+  - dk: LP token amount
 
-### Swap
+### Quote Function
 
 ```clarity
-(swap
-  (
-    (amount uint)
-    (opcode (optional (buff 16)))
-  )
-  (response uint uint))
+(quote (amount uint) (opcode (optional (buff 16))))
 ```
 
-Swaps one token for another. The direction of the swap is determined by the first byte of the opcode buffer (0x00 for token A input, 0x01 for token B input).
+The quote function provides expected outputs for operations without execution:
 
-## Quote Functions
+- Amount: The primary input amount to quote
+- Opcode: Same opcode buffer that would be used in execute
+- Returns: Same tuple format as execute
 
-### Add Liquidity Quote
+## OPCODE Specification
 
-```clarity
-(get-add-liquidity-quote
-  (
-    (amount uint)
-    (opcode (optional (buff 16)))
-  )
-  (response 
-    (tuple (dx uint) (dy uint) (dk uint))
-    uint))
-```
+The first byte of the opcode buffer determines the core operation:
 
-Returns expected amounts for adding liquidity.
+| Value | Operation | Description |
+|-------|-----------|-------------|
+| 0x00 | SWAP_A_TO_B | Swap token A for token B |
+| 0x01 | SWAP_B_TO_A | Swap token B for token A |
+| 0x02 | ADD_LIQUIDITY | Add liquidity to pool |
+| 0x03 | REMOVE_LIQUIDITY | Remove liquidity from pool |
 
-### Remove Liquidity Quote
+### Operation Details
 
-```clarity
-(get-remove-liquidity-quote
-  (
-    (amount uint)
-    (opcode (optional (buff 16)))
-  )
-  (response 
-    (tuple (dx uint) (dy uint) (dk uint))
-    uint))
-```
+#### Swap Operations (0x00, 0x01)
+- Amount represents input token quantity
+- dx/dy represent input/output amounts
+- dk is unused (zero)
 
-Returns expected amounts for removing liquidity.
+#### Add Liquidity (0x02)
+- Amount represents desired LP tokens
+- dx/dy represent token deposits required
+- dk represents LP tokens minted
 
-### Swap Quote
+#### Remove Liquidity (0x03)
+- Amount represents LP tokens to burn
+- dx/dy represent tokens returned
+- dk represents LP tokens burned
 
-```clarity
-(get-swap-quote
-  (
-    (amount uint)
-    (opcode (optional (buff 16)))
-  )
-  (response 
-    (tuple (dx uint) (dy uint))
-    uint))
-```
+## Implementation Guidelines
 
-Returns expected amounts for a swap.
+### Core Requirements
 
+1. Must implement both execute and quote functions
+2. Must handle missing/empty opcode buffer gracefully
+3. Must return consistent tuple format for all operations
+4. Must implement SIP-010 trait for LP token
+5. Quote must accurately reflect execute behavior
 
+### Security Considerations
 
-## Trait Implementation
+1. Post conditions must be used for slippage protection
+2. All state changes must occur atomically
+3. Rounding must favor the pool
+4. Operation validation must occur before state changes
 
-```clarity
-(define-trait liquidity-pool-trait
-  (
-    ;; Liquidity Operations
-    (add-liquidity (uint (optional (buff 16))) 
-      (response (tuple (dx uint) (dy uint) (dk uint)) uint))
-    (remove-liquidity (uint (optional (buff 16))) 
-      (response (tuple (dx uint) (dy uint) (dk uint)) uint))
-    
-    ;; Swap Operations
-    (swap (uint (optional (buff 16))) (response uint uint))
-    
-    ;; Quotes
-    (get-add-liquidity-quote (uint (optional (buff 16))) 
-      (response (tuple (dx uint) (dy uint) (dk uint)) uint))
-    (get-remove-liquidity-quote (uint (optional (buff 16))) 
-      (response (tuple (dx uint) (dy uint) (dk uint)) uint))
-    (get-swap-quote (uint (optional (buff 16))) 
-      (response (tuple (dx uint) (dy uint)) uint))
-    
-  )
-)
-```
+### Best Practices
+
+1. Document default behavior without opcodes
+2. Use descriptive error codes
+3. Validate parameter ranges
+4. Include clear logging/events
+5. Document fee structures
 
-# Implementation Guidelines
+## Multi-Hop Router Integration
 
-## AMM Design Flexibility
-- Implementations may use any pricing formula or AMM design
-- Quote functions must accurately reflect the actual behavior of the pool
-- Pool behavior can be modified through opcode parameters
+The standard enables efficient path execution through a router contract that can:
 
-## Fee Structure
-- Fees and rebates can be implemented freely
-- Quote functions must accurately reflect all fees and rebates
-- Fee behavior can be modified through opcode parameters
+1. Chain multiple pool operations
+2. Support routes up to 9 hops
+3. Automatically propagate output amounts
+4. Maintain consistent slippage protection
 
-## Liquidity Operations
-- Default behavior for add-liquidity should be documented
-- Opcode parameters can modify liquidity allocation
-- Support for single-sided, imbalanced, and oracle-weighted deposits
+Example router functions:
 
-## Post Conditions
-- All slippage protection must be implemented using post conditions
-- Post conditions should account for any opcode-modified behavior
+```clarity
+;; Single hop swap
+(define-public (swap-1 
+    (amount uint) 
+    (hop-1 {pool: <pool-trait>, opcode: (optional (buff 16))}))
+  (let ((result (try! (execute-swap amount hop-1))))
+    (ok (list result))))
 
-## Opcode Buffer Implementation
-- Must handle missing or partial opcode buffers gracefully
-- Unknown opcodes should be ignored
-- Default behavior must be clearly documented
-- All opcode-modified behaviors must be reflected in quotes
+;; Multi-hop swap
+(define-public (swap-2
+    (amount uint)
+    (hop-1 {pool: <pool-trait>, opcode: (optional (buff 16))})
+    (hop-2 {pool: <pool-trait>, opcode: (optional (buff 16))}))
+  (let (
+    (result-1 (try! (execute-swap amount hop-1)))
+    (result-2 (try! (execute-swap (get dy result-1) hop-2))))
+    (ok (list result-1 result-2))))
+```
 
 # Applications
 
 ## Swap Aggregators
-Aggregators implementing this standard should:
-1. Query pool info to discover token pairs and reserves
-2. Use quote functions to calculate optimal routes
-3. Set appropriate post conditions for slippage protection
-4. Properly construct opcode buffers for complex operations
+Aggregators implementing this standard can:
+1. Query pools implementing the trait
+2. Calculate optimal routes
+3. Execute atomic multi-hop swaps
+4. Provide accurate quotes
 
 ## Direct Integration
-Applications directly integrating with pools should:
-1. Verify pool and token contracts implement required traits
-2. Use get-pool-info to fetch current state
-3. Get quotes before executing operations
-4. Handle opcode buffer construction appropriately
+Applications directly integrating should:
+1. Verify trait implementation
+2. Get quotes before execution

-### Operation Details
+### Operation Types (Byte 0)
 
-#### Swap Operations (0x00, 0x01)
-- Amount represents input token quantity
-- dx/dy represent input/output amounts
+```clarity
+(define-constant OP_SWAP_A_TO_B 0x00)     ;; Swap token A for B
+(define-constant OP_SWAP_B_TO_A 0x01)     ;; Swap token B for A
+(define-constant OP_ADD_LIQUIDITY 0x02)   ;; Add liquidity
+(define-constant OP_REMOVE_LIQUIDITY 0x03) ;; Remove liquidity
+```
+
+### Swap Types (Byte 1)
+
+```clarity
+(define-constant SWAP_EXACT_INPUT 0x00)    ;; Exact input amount
+(define-constant SWAP_EXACT_OUTPUT 0x01)   ;; Exact output amount
+```
+
+### Fee Types (Byte 2)
+
+```clarity
+(define-constant FEE_REDUCE_INPUT 0x00)    ;; Fee reduces input amount
+(define-constant FEE_REDUCE_OUTPUT 0x01)   ;; Fee reduces output amount
+(define-constant FEE_BURN_ENERGY 0x02)     ;; Fee burns protocol token
+```
+
+### Liquidity Types (Byte 3)
+
+```clarity
+(define-constant LIQUIDITY_BALANCED 0x00)  ;; Balanced liquidity add/remove
+```
+
+## Operation Details
+
+### Swap Operations (0x00, 0x01)
+- Amount represents exact input token quantity
+- dx represents input amount after fees
+- dy represents output amount
 - dk is unused (zero)
+- Fee calculation determined by byte 2 (FEE_TYPE)
 
-#### Add Liquidity (0x02)
+### Add Liquidity (0x02)
 - Amount represents desired LP tokens
 - dx/dy represent token deposits required
-- dk represents LP tokens minted
+- dk represents actual LP tokens minted
+- Liquidity type in byte 3 determines ratio calculation
 
-#### Remove Liquidity (0x03)
+### Remove Liquidity (0x03)
 - Amount represents LP tokens to burn
 - dx/dy represent tokens returned
 - dk represents LP tokens burned
+- Liquidity type in byte 3 determines withdrawal strategy
 
 ## Implementation Guidelines
 
 ### Core Requirements
 
-1. Must implement both execute and quote functions
-2. Must handle missing/empty opcode buffer gracefully
-3. Must return consistent tuple format for all operations
-4. Must implement SIP-010 trait for LP token
-5. Quote must accurately reflect execute behavior
+1. Must implement both execute and quote functions exactly as specified
+2. Must handle missing/empty opcode by defaulting to SWAP_A_TO_B with FEE_REDUCE_INPUT
+3. Must implement SIP-010 trait for LP token
+4. Quote must accurately predict execute behavior
+5. Must use consistent precision (6 decimals recommended)
 
 ### Security Considerations
 
-1. Post conditions must be used for slippage protection
+1. Must implement comprehensive post conditions
 2. All state changes must occur atomically
-3. Rounding must favor the pool
-4. Operation validation must occur before state changes
-
-### Best Practices
-
-1. Document default behavior without opcodes
-2. Use descriptive error codes
-3. Validate parameter ranges
-4. Include clear logging/events
-5. Document fee structures
+3. Rounding must favor the pool (floor for outputs)
+4. Must validate opcode format before execution
+5. Must implement proper principal checks
 
 ## Multi-Hop Router Integration
 
-The standard enables efficient path execution through a router contract that can:
-
-1. Chain multiple pool operations
-2. Support routes up to 9 hops
-3. Automatically propagate output amounts
-4. Maintain consistent slippage protection
-
-Example router functions:
+The standard enables path execution through a router contract with functions for 1-9 hops:
 
 ```clarity
-;; Single hop swap
+;; Router function type pattern
+(define-public (swap-{n}
+    (amount uint)
+    (hop-1 {pool: <pool-trait>, opcode: (optional (buff 16))})
+    ...
+    (hop-n {pool: <pool-trait>, opcode: (optional (buff 16))}))
+    (response (list 9 {dx: uint, dy: uint, dk: uint}) uint))
+
+;; Example single-hop implementation  
 (define-public (swap-1 
     (amount uint) 
     (hop-1 {pool: <pool-trait>, opcode: (optional (buff 16))}))
-  (let ((result (try! (execute-swap amount hop-1))))
-    (ok (list result))))
-
-;; Multi-hop swap
-(define-public (swap-2
-    (amount uint)
-    (hop-1 {pool: <pool-trait>, opcode: (optional (buff 16))})
-    (hop-2 {pool: <pool-trait>, opcode: (optional (buff 16))}))
   (let (
-    (result-1 (try! (execute-swap amount hop-1)))
-    (result-2 (try! (execute-swap (get dy result-1) hop-2))))
-    (ok (list result-1 result-2))))
+    (pool (get pool hop-1))
+    (opcode (get opcode hop-1))
+    (result (try! (contract-call? pool execute amount opcode))))
+    (ok (list result))))
 ```
 
-# Applications

-## Swap Aggregators
-Aggregators implementing this standard can:
-1. Query pools implementing the trait
-2. Calculate optimal routes
-3. Execute atomic multi-hop swaps
-4. Provide accurate quotes
-
-## Direct Integration
-Applications directly integrating should:
-1. Verify trait implementation
-2. Get quotes before execution
-3. Set appropriate post conditions
-4. Handle operation failures gracefully
