Functions

operate

Single function which handles supply, withdraw, borrow & payback

*to trigger skipping in / out transfers when in&out amounts balance themselves out (gas optimization):

  • supply(+) == borrow(+), withdraw(-) == payback(-).
  • withdrawTo_ / borrowTo_ must be msg.sender (protocol)
  • callbackData_ MUST be encoded so that "from" address is at last 20 bytes (if this optimization is desired), also for native token operations where liquidityCallback is not triggered! from address must come at last position if there is more data. I.e. encode like: abi.encode(otherVar1, otherVar2, FROM_ADDRESS). Note dynamic types used with abi.encode come at the end so if dynamic types are needed, you must use abi.encodePacked to ensure the from address is at the end.*
