The GluexRouter smart contract (version 1.1) represents an optimized iteration of our routing infrastructure. It provides enhanced functionality for highly efficient token routing, dynamic fee collection and the precise execution of onchain interactions through a refined, structured interface. This version introduces advanced mechanisms for surplus and slippage sharing

​
Deployment

The GluexRouter-v1.1 contract is deployed at the following address on the supported chains by GlueX: Contract Address: 0xe95F6EAeaE1E4d650576Af600b33D9F7e5f9f7fd

Functions

​
Swap

Executes a token routing operation through an external IExecutor contract using a predefined set of interactions Function Signature 
function swap(
    IExecutor executor,
    RouteDescription calldata desc,
    Interaction[] calldata interactions
) external payable returns (uint256 finalOutputAmount);
Parameters
  • executor (IExecutor): The executor contract responsible for processing interactions
  • desc (RouteDescription calldata): A structured object containing input/output token information, fees, limits and recipient addresses
  • interactions (Interaction[] calldata): An array of interaction steps to be executed by the executor
Returns
  • finalOutputAmount (uint256): The final amount of output token received by the outputReceiver after fees and surplus/slippage sharing
Reverts
  • InvalidNativeTokenInputAmount: If the ETH value sent does not match the expected input amount
  • RoutingFeeTooHigh: If desc.routingFee exceeds the maximum allowed fee (_MAX_FEE)
  • RoutingFeeTooLow: If desc.routingFee is below the minimum required fee (_MIN_FEE)
  • PartnerSurplusShareTooHigh: If desc.partnerSurplusShare exceeds _MAX_PARTNER_SURPLUS_SHARE_LIMIT
  • ProtocolSurplusShareTooLow: If desc.protocolSurplusShare is below _MIN_PROTOCOL_SURPLUS_SHARE_LIMIT
  • PartnerSlippageShareTooHigh: If desc.partnerSlippageShare exceeds _MAX_PARTNER_SLIPPAGE_SHARE_LIMIT
  • ProtocolSlippageShareTooLow: If desc.protocolSlippageShare is below _MIN_PROTOCOL_SLIPPAGE_SHARE_LIMIT
  • ZeroAddress: If any required address (eg: inputReceiver, outputReceiver) is a zero address
  • InvalidSlippage: If desc.minOutputAmount is zero
  • SlippageLimitTooLarge: If desc.minOutputAmount exceeds desc.outputAmount
  • InsufficientBalance: If the router does not hold sufficient balance for the intended transfer
  • NativeTransferFailed: If the native token transfer fails
