META is a reward token that gives you above average BUSD rewards just by holding it in your wallet.
It is the main engine of the MetaSwap ecosystem.
DEX
MetaSwap is working towards a automate market maker decentralised exchange putting all your Metas into one location.
FARMS
Metaswap will introduce you to a world of Meta with unbeatable APR farms where we will tram up with different projects to offer there token in farms.
TRANSPERENCY & TRUST
We are 100% transparent with every transaction been available for viewing on bscscan. Trust is something that comes with it the devs of MetaSwap is always available to answer any questions in our Telegram group.

MetaSwap.swapBack() (#743-786) sends eth to arbitrary user
Dangerous calls:
- (successMarketing) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#770)
Ensure that an arbitrary user cannot withdraw unauthorized funds.
