Function call analysis

• this._claimRewards(tokenId) -> SafeERC20.safeTransfer(IERC20(this.tranche.asset()), this._ownerOf(tokenId), this.rewardsByTokenId[tokenId])

  • What is controllable? this._ownerOf(tokenId) and this.rewardsByTokenId[tokenId].

  • If the return value is controllable, how is it used and how can it go wrong? The reward amount is transferred to the owner of the token; an incorrect owner may result in incorrect reward transfer.

  • What happens if it reverts, reenters, or does other unusual control flow? If it reverts, the entire call will revert — no reentrancy scenarios.

• this._claimRewards(tokenId) -> this.tranche.asset()

  • What is controllable? N/A.

  • 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? N/A.
