ExactInSwapRoute

ExactInSwapRoute executes a multi-hop swap with exact input amount. Parameters: - inputToken: path of input token - outputToken: path of output token - amountIn: exact input amount - routeArr: encoded route array - quoteArr: encoded quote array - amountOutMin: minimum output amount - deadline: transaction deadline - referrer: referrer address for reward tracking Returns: - string: actual input amount - string: actual output amount

ExactInSingleSwapRoute

ExactInSingleSwapRoute executes a single-hop swap with exact input amount. Parameters: - inputToken: path of input token - outputToken: path of output token - amountIn: exact input amount - routeArr: encoded route - amountOutMin: minimum output amount - sqrtPriceLimitX96: price limit for the swap - deadline: transaction deadline - referrer: referrer address for reward tracking Returns: - string: actual input amount - string: actual output amount

ExactOutSwapRoute

ExactOutSwapRoute executes a multi-hop swap with exact output amount. Parameters: - inputToken: path of input token - outputToken: path of output token - amountOut: exact output amount - routeArr: encoded route array - quoteArr: encoded quote array - amountInMax: maximum input amount - deadline: transaction deadline - referrer: referrer address for reward tracking Returns: - string: actual input amount - string: actual output amount

ExactOutSingleSwapRoute

ExactOutSingleSwapRoute executes a single-hop swap with exact output amount. Parameters: - inputToken: path of input token - outputToken: path of output token - amountOut: exact output amount - routeArr: encoded route - amountInMax: maximum input amount - sqrtPriceLimitX96: price limit for the swap - deadline: transaction deadline - referrer: referrer address for reward tracking Returns: - string: actual input amount - string: actual output amount

DrySwapRoute

DrySwapRoute simulates a swap route without executing it. Parameters: - inputToken: path of input token - outputToken: path of output token - specifiedAmount: specified amount for the swap - swapTypeStr: swap type string ("ExactIn" or "ExactOut") - strRouteArr: encoded route array - quoteArr: encoded quote array - tokenAmountLimit: token amount limit Returns: - string: estimated input amount - string: estimated output amount - bool: success status

SwapCallback

SwapCallback is called by pools to transfer tokens during a swap.

GetSwapFee

GetSwapFee retrieves the current swap fee. If not set, returns the default swap fee.

SetSwapFee

SetSwapFee stores the swap fee.

NewRouterStore

NewRouterStore creates a new router store instance with the provided KV store. This function is used by the upgrade system to create storage instances for each implementation.

IRouter

IRouterStore

RegisterInitializer

RegisterInitializer registers a new router implementation version. This function is called by each version (v1, v2, etc.) during initialization to register their implementation with the proxy system. The initializer function creates a new instance of the implementation using the provided routerStore interface. Security: Only contracts within the domain path can register initializers. Each package path can only register once to prevent duplicate registrations.

UpgradeImpl

UpgradeImpl switches the active router implementation to a different version. This function allows seamless upgrades from one version to another without data migration or downtime. Security: Only admin or governance can perform upgrades. The new implementation must have been previously registered via RegisterInitializer.

GetImplementationPackagePath

GetImplementationPackagePath returns the package path of the currently active implementation.
