BSC Hertz hard fork integration tests

This repository contains integration tests for the BEPs of the Hertz hard fork of BSC. The tests use a BSC Go client to send transactions to a running BSC node and check the outcome for a variety of different scenarios.

Prerequisites

You need to be running a BSC node with Hertz, Berlin and London blocks activated at a certain block height.

The genesis config should define the block heights for berlinBlock, londonBlock and hertzBlock at the same height:

      "berlinBlock": 10,
      "londonBlock": 10,
      "hertzBlock": 10,

Also the account that will send the transactions in the tests should be prefunded in the genesis file. This can be done by adding a line in the alloc section of the genesis file. For example:

   "9fB29AAc15b9A4B7F17c3385939b007540f4d791": {
      "balance": "0x84595161401484a000000"
    }

An example genesis file with all these requirements can be found in genesis.json.

Start the BSC node

./build/bin/geth --datadir node_dir init genesis.json
./build/bin/geth --datadir node_dir console --http --http.corsdomain https://remix.ethereum.org --allow-insecure-unlock --http.api personal,eth,net,web3,debug --http.vhosts '*,localhost,host.docker.internal' --http.addr "0.0.0.0" --rpc.allow-unprotected-txs --networkid 1337 --miner.etherbase 0x9fb29aac15b9a4b7f17c3385939b007540f4d791 --vmdebug

Start block production

personal.importRawKey("9b28f36fbd67381120752d6172ecdcf10e06ab2d9a1367aac00cdcd6ac7855d3", "123456") 
personal.unlockAccount("0x9fb29aac15b9a4b7f17c3385939b007540f4d791", "123456", 300000000) 
miner.start()

Running the tests

You can tweak the parameters for the tests in the config/constants.go file. There you can configure at which block height to run the tests before and after the hard fork.

Double-check that the following lines are included in the go.mod file to ensure that the BSC Go client is used instead of the Ethereum Go client:

replace github.com/ethereum/go-ethereum v1.11.6 => github.com/bnb-chain/bsc v1.1.21

replace github.com/btcsuite/btcd => github.com/btcsuite/btcd v0.23.0

replace github.com/cometbft/cometbft => github.com/bnb-chain/greenfield-tendermint v0.0.0-20230417032003-4cda1f296fb2

replace github.com/grpc-ecosystem/grpc-gateway/v2 => github.com/prysmaticlabs/grpc-gateway/v2 v2.3.1-0.20210702154020-550e1cd83ec1

replace github.com/tendermint/tendermint => github.com/bnb-chain/tendermint v0.31.15

You can run the tests for a certain EIP using go run <testFile.go>. For example to run the EIP-1559 tests you should run go run eip1559/tests.go

!!! Please make sure you run the tests before the hard fork block, otherwise the pre-Hertz test cases won't be able to run!
