pancake-swap-periphery's Issues

PancakeLibrary invalid code

Compile issue

pancake-swap-periphery/contracts/PancakeRouter.sol

Line 3 in d769a6d

import '@uniswap/v2-core/contracts/interfaces/IPancakeFactory.sol';

Pancake Swap Router failed to output any BNB back to originating wallet address (lost ~$507 worth of BNB on a 3.275 FIL for 1.21 BNB swap)

My swap of 3.275 FIL for 1.21 BNB succeeded at withdrawing input FIL coin but failed to output any BNB from the router back to my wallet. The money never showed up, and the FIL coin is gone from the wallet. Take a look at the transaction here:

https://bscscan.com/tx/0x9622b50f8e702cfca538cfd3e2612132491453d8656ac002bad652ce6576fddc

Any ideas how this could happen and why the router didn't output any BNB? Kinda bummed about losing $500 bucks after doing so many swaps flawlessly - I just didn't think to test every pair I swapped with a micro transaction :/

What does this line mean?

pancake-swap-periphery/contracts/libraries/PancakeLibrary.sol

Line 31 in d769a6d

pairFor(factory, tokenA, tokenB);

Please share the contract addresses of V2

There should be some official documentation when new contract are deployed with factory and router addresses!

Bug Report: Type Conversion from uint256 to address

hey,

when use address to convert uint , it prompts that "Cannot convert uint256 into address".

uint means uint256, address means bytes20, so this conversion in the pancakeSwap source codes should
not work , but as I know , this code works for PancakeSwap .

what happened ? its for solidity compiler version?

  // calculates the CREATE2 address for a pair without making any external calls
    function pairFor(address factory, address tokenA, address tokenB) internal pure returns (address pair) {
        (address token0, address token1) = sortTokens(tokenA, tokenB);
        pair = address(uint(keccak256(abi.encodePacked(
                hex'ff',
                factory,
                keccak256(abi.encodePacked(token0, token1)),
                hex'd0d4c4cd0848c93cb4fd1f498d7013ee6bfb25783ea21593d5834f5d250ece66' // init code hash
            ))));
    }

how can i get the periphery contract address on bsc test and mainnet?

Tests are failing

I forked, and pulled the pancake. Then I manually set the links to the Pancake-swap core contracts. As it was reported in issue #10

Now compilation works. However tests are failing.

$ yarn compile
$ yarn clean

I added liquidity to a pool and now I am unable to retrieve it please help.

Note: Liquidity is v2 and everything is v2!

And if I click on remove nothing happens at all.

CREATE2 init code hash is not correct

Hi there, as I was trying to call the pairFor() method from the PancakeLibrary to compute the CREATE2 address of a token pair, I noticed that the address did not match the ones returned from the router.

After a closer look, I realized the hardcoded value, see line 24 of Pancake Library does not match the INIT_CODE_PAIR_HASH that was computed by the Factory. You can find the actual value here.

Using the value obtained from BSCscan, it resolves the issue that I had and I was able to get the correct pair address. I thought I would raise this issue for anyone who's also having a hard time with this.

Dependency Error

The dependency at line 3 of file PancakeRouter is @uniswap/v2-core/contracts/interfaces/IPancakeFactory.sol, but there are no IPancakeFactory.sol file.

How can I fix this problem so that I can compile contract without error.
