🧐 Motivation
Create simple ERC20 and ERC777 presets with fixed supply.
The benefits are:

• Easy to deploy (including from Remix).
• No access control (for minting/pausing), and hence no governance required.
• Can be verified easily on public networks and then are verified for all.

Community members are creating their own simple ERC20 tokens, so it would be good if they

What is wrong?

EIP-2027, aka Code Merklization is coming down the EIP pipeline. It would be nice to have a basic implementation of it.

How can it be fixed

Implement a stand-alone API for merklizing code. I'd recommend something loosely using the following structure:

from typing import NamedTuple

class MerklizedCode(Name

The check block in the peer-communication.ts example should be updated to the latest fork.

The following PR can be used for guidance ethereumjs/ethereumjs-devp2p#54 (this is missing the header RLP though).

Currently, we are not able to
a) symbolically execute init code with symbolic arguments
b) get srcmapping for init code with arguments

We could change ContractCode as follows:

data ContractCode
  = InitCode (ByteString, Buffer)    -- ^ "Constructor" code, during contract creation (possibly with arguments)
  | RuntimeCode ByteString           -- ^ "Instance" code, after contract crea

We should create a corpus of tests to verify that CFG recovery is accurate and complete, and there are no regressions.

recently CI failed many times testing cluster because of port already used, which can be very annoying.

The ethabi::errors::InvalidData error could use some more info such that the user can find which part of their input is invalid.
