Deposits don't work with fee-on transfer tokens

Handle cmichel Vulnerability details There are ERC20 tokens that may make certain customizations to their ERC20 contracts. One type of these tokens is deflationary tokens that charge a certain fee for every transfer or transferFrom. Others are rebasing tokens that increase in value over time like...

redeemToken can fail for certain tokens

Handle cmichel Vulnerability details The SwappableYieldSource.redeemToken function transfers tokens from the contract back to the sender, however, it uses the ERC20.transferFromaddressthis, msg.sender, redeemableBalance function for this. Some deposit token implementations might fail as...

Incorrect address check in transferERC20 can allow rugging

Handle 0xRajeev Vulnerability details Impact SwappableYieldSource.sol has a transferERC20 function callable only by the owner or asset manager to transfer out ERC20 tokens other than the yield source's tokens held by this contract. This is similar to the functions in ATokenYieldSource and...
