The tranche is described as providing a wrapper to the underlying ERC4626 tokens, but does not currently support ERC4626 itself. SeniorTranche and JuniorTranche do not implement certain ERC4626 functions.
Technical Details
To clarify, the tranche tokens do not currently implement ERC4626 but the documentation uses the word "ERC4626 wrapper" when describing the tranche, which could be misleading. GVault and tranche tokens import the same ERC4626 to implement basic ERC4626 support. GVault overrides many virtual functions from this import to implement them correctly according to ERC4626 specifications, but GTranche does not. The functions that should be implemented in GTranche to comply with ERC4626 include:
mint()
deposit()
withdraw()
redeem()
convertToShares()
convertToAssets()
maxRedeem()
previewRedeem()
maxWithdraw()
previewWithdraw()
maxMint()
previewMint()
maxDeposit()
previewDeposit()
Impact
Informational.
Recommendation
Consider updating the documentation to remove the word "wrapper" and to clarify that the tranche tokens are not exactly ERC4626 tokens themselves but rather ERC20 tokens.
Acknowledged: Will clarify documentation to communicate that Tranche tokens aren't eip4626 tokens, but rather are a basked of eip-4626 compatible tokens.
