+
+NOTE: Uniswap Universal Router uses address constants internally, for example
+
+```Javascript
+export const MSG_SENDER: string = '0x0000000000000000000000000000000000000001'
+export const ADDRESS_THIS: string = '0x0000000000000000000000000000000000000002'
+```
+- '0x0000000000000000000000000000000000000001' is msg.sender (EOA) address itself
+- '0x0000000000000000000000000000000000000002' is Universal Router Contract address itself
