After ethereum/solidity#10737 we should be able to replace nearly all non-range-based for loops by range-based loops using appropriate ranges.

🎉 Description

The ECDSA contract has a function toEthSignedMessage(bytes32), but we should have a function that works for any length of a bytes array:

function toEthSignedMessage(bytes s) pure internal returns (bytes32) {
  return keccak256(
    "\x19Ethereum Signed Message:\n",
    uintToBytes(s.length),
    s);
}

Where uintToBytes is implemented from an ideally

Maybe this is caused by me not being a native speaker but the following sentence in the README under the section Configure seems to be mixed up a bit.

You can configure your node's behavior by setting environment variables which can be, along with default values that get used if no corresponding environment variable is found.

We can rely on the internal storage information and web3.get_storage_at to return the value of a contract onchain

Example of API

• slither-read-storage [codebase] 0x414141 canonical_variable_name
• slither-read-storage 0x414141 canonical_variable_name (if the source code is on etherscan)

Potential

BuidlerError and BuidlerPluginError instances aren't print nicely in node's console. We should provide custom inspect methods to change this.

I left a review and then got this message

which seems strange as it's telling me something I know.

We can safely disallow any use of solc below 0.4.25.
