Token 8 months

LEO is the first metasverse game application in SGR ecology. In the future, it will revolve around eight elements of the metasurverse: Identity, friends, immersive, low latency, pluralism, anywhere, economic system and culture, makes a game by the social attribute, the attribute, scrip attribute as one of the perfect combination, and through this social + + game flat t the combination of economic, can satisfy people work and play in the virtual world, consumer demand, Thus presenting a METAVERSE classic ecology

External calls:

LEO._beforeTokenTransfer(address,address,uint256) (#206-249) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp >= startTradeTime,not start exchange) (#223)
- require(bool)(fiveWriteList[_to] || block.timestamp >= startTradeTime + _FIVE_MIN) (#224)
- require(bool,string)(block.timestamp >= startTradeTime,not start exchange) (#233)
- require(bool)(fiveWriteList[_from] || block.timestamp >= startTradeTime + _FIVE_MIN) (#234)
Avoid relying on block.timestamp.

ERC20._transfer(address,address,uint256) (#141-151) compares to a boolean constant:
-require(bool,string)(blackList[msg.sender] == false && blackList[sender] == false && blackList[recipient] == false,ERC20: is black List !) (#143)
Remove the equality to the boolean constant.

Pragma version0.8.1 (#2) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6
solc-0.8.1 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.
