Euler.Tools is a new way to understand the blockchain. We are translating the complex architecture into delightful and reusable data representations that should provide insight on the transactions. Starting with our Euler explorer, and moving towards a trading interface, we will introduce a smooth user experience focused on explaining the blockchain. Backed by a utility token that can be used both for payments or liquidity mining, we will create a deflationary mechanism by buying back tokens and burning them.

Pragma version>=0.6.0<0.8.0 (#3) is too complex
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.sendValue(address,uint256) (#658-664):
- (success) = recipient.call{value: amount}() (#662)
Low level call in Address.functionCallWithValue(address,bytes,uint256,string) (#719-726):
- (success,returndata) = target.call{value: value}(data) (#724)
Low level call in Address.functionStaticCall(address,bytes,string) (#744-750):

Low level call in Address.functionDelegateCall(address,bytes,string) (#768-774):
- (success,returndata) = target.delegatecall(data) (#772)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Contract name (Euler.Tools) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.
Contract has 1% buy tax and 0% sell tax.
Taxes are low but contract ownership is not renounced. Token has a high risk of becoming a honeypot.
Token is deployed only at one blockchain
