Function call analysis

• SafeERC20Upgradeable.safeTransferFrom(this._assetIERC20(), sender, address(this), assets)

  • What is controllable? Only assets.

  • If the return value is controllable, how is it used and how can it go wrong? N/A.

  • What happens if it reverts, reenters or does other unusual control flow? If the transfer fails, the call reverts. If there is reentrancy due to a future USDC upgrade that adds outgoing hooks, the state of the contract is the same and valid both before and after the transfer.
