Description

In the initializer for Tranche, the ERC-20 initializer is called with j concatenated onto the name of the underlying asset:

__ERC20_init_unchained(
    string(abi.encodePacked(trancheName,
        abi.encodePacked(" Tranche ", ERC20(__asset).name()))),
    string(abi.encodePacked("j", ERC20(__asset).symbol()))
);

However, this means that both the junior and senior tranches use j and then the underlying asset symbol.

Impact

Holders of senior tranche tokens may be misled by the incorrect name.

Recommendations

Set the symbol depending on the name of the tranche.
