In the `Swan::purchase(address _asset) function`, the `bool` return value of the token transfer is currently ignored. If the transfer fails for instance, due to insufficient funds or if the recipient address reverts on receiving ERC20 tokens—the function will complete without reverting, leading to a state where the transfer appears successful, but the recipient will not actually receive the tokens. Ignoring the transfer's success status could result in unintended behavior and discrepancies in account balances.

function purchase(address _asset) external {

=> token.transferFrom(listing.buyer, address(this), listing.price);

=> token.transfer(listing.seller, listing.price);

}
