Closes #1286

Instructions:

Starting Blockscout (1 tab)

  1. Clone the Blockscout repo (https://github.com/blockscout/blockscout)
  2. Cd into blockscout/docker-compose and run docker compose -f hardhat-network.yml up (-d to daemonize)

Blockscout will start running on localhost:80 by default

Starting Hardhat (2 tabs)

  1. Run npx hardhat node as per usual
  2. Run npx hardhat deploy --network development as per usual

At this point Blockscout will start picking up the transactions

Todo:

Currently, contract verification is not working. This is as far as I've gotten:

>> npx hardhat verify --network development 0x777760996135F0791E2e1a74aFAa060711197777  --contract contracts/common/EtherRouter.sol:EtherRouter        
Successfully submitted source code for contract
contracts/common/EtherRouter.sol:EtherRouter at 0x777760996135F0791E2e1a74aFAa060711197777
for verification on the block explorer. Waiting for verification result...

We tried verifying your contract EtherRouter without including any unrelated one, but it failed.
Trying again with the full solc input used to compile and deploy it.
This means that unrelated contracts may be displayed on Etherscan...

hardhat-verify found one or more errors during the verification process:

Etherscan:
A network request failed. This is an error from the block explorer, not Hardhat. Error: Unexpected token '<', "<html>
<h"... is not valid JSON

I've debugged enough to confirm that the API is live, but for some reason the 2nd step (verifying with the full solc input) returns an HTML response, which breaks the verifier.
