Smart Contracts
Allowance should be given to TokenTransferProxy contract and not to AugustusSwapper, FUNDS MAY BE LOST OTHERWISE!
The contract router is responsible for making swaps.
The Spender contract is responsible for moving ERC20 tokens (and equivalents on side chains). To get the address, you can call
getTokenTransferProxy() on Augustus.pragma solidity 0.7.5;
