PolkaBridge is a decentralized all-in-one application platform.
One of PolkaBridge’s most noticeable product is PolkaBridge DEX - a decentralized exchange that allows users to swap tokens on Polkadot to other ones on other blockchain platforms without any centralized organizations. In addition, with the smart deflationary farming mechanism, liquidity providers can earn more rewards than they think.
In future, we will launch Lending, Launchpad, Predict and more to scale up ecosystem.

report
Token seems to be (relatively) fine. It still become a scam, but probability is moderate.

MintSwapCanonicalToken.withdrawErc20(IERC20,address) (#987-989) ignores return value by _token.transfer(_acc,_token.balanceOf(address(this))) (#988)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Pragma version>=0.8.0 (#4) allows old versions
solc-0.8.2 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Low level call in Address.functionDelegateCall(address,bytes,string) (#637-646):

Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
