Router

Because routers are stateless and do not hold token balances, they can be replaced safely and trustlessly, if necessary. This may happen if more efficient smart contract patterns are discovered, or if additional functionality is desired.

Address

ZeniqSwapRouter is deployed at 0x7963c1bd24E4511A0b14bf148F93e2556AFe3C27 on the Zeniq Smart Chain.

Read-Only Functions

factory​

function factory() external pure returns (address);

Returns factory address.

WZENIQ​

function WETH() external pure returns (address);

Returns the WZENIQ Address: 0x74DC1C4ec10abE9F5C8A3EabF1A90b97cDc3Ead8 deployed on the Zeniq Smart Chain
