Use of block.timestamp allows validators to hold transactions and it doesn't serve as an adequate protection against slippage
Summary
Use of block.timestamp allows validators to hold transactions and it doesn't serve as an adequate protection against slippage.
Vulnerability Details
Using block.timestamp means a transaction will only go through when included in the mined blocks by validators. This can result to a loss.
Crypto is volatile. The time frame a transaction should go through shouldn't be pegged to block.timestamp. As it is, the contract is at the mercy of validators.
Impact
There could be delay in adding the transaction to the block. And this can result to getting fewer tokens out.
