🎉 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

       Check to see that your provider is valid.
       If you have a slow internet connection, try configuring a longer timeout in your Truffle config. Use the networks[networ

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

I run: cd ~/.chainlink && docker run -p 6688:6688 -v ~/.chainlink:/chainlink -it --env-file=.env smartcontract/chainlink:0.10.1 local n

I get the following result:

Given a contract like this:

Create a tool for debugging hardhat project that

• Add console.log at every function/modifier entry point, with the canonical name of the function, and the function parameters
• Add console.log at every end of the function/modifier, with the canonical name of the function, and the return values

Potential flags

• --only contract/function
• --exclude contract/function
• `--force-patc

We can safely disallow any use of solc below 0.4.25.

I left a review and then got this message

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