Hardhat configs

Repository for our Hardhat: https://github.com/silesiacoin/hardhat

Hardhat l14-testnet config:

module.exports = {
  solidity: "0.7.3",
  networks: {
    hardhat: {
      forking: {
        url: "https://rpc.l14.lukso.network"
      },
    }
  }
};

Known issues

Transaction gas price supplied is too low. There is another transaction with same nonce in the queue. Try increasing the gas price or incrementing the nonce. comes from https://github.com/ethereum-optimism/contracts-v2/blob/master/bin/deploy.js deploy script and:

suggestion is that there is some missing async/await;
solution is to implement manual nonce increaser - not sure because Hardhat (builder) or truffle uses auto there;
Also these lines https://github.com/ethereum-optimism/contracts-v2/blob/525477144ecc6fc019e0ada225b85f322c6b5fbc/src/contract-deployment/deploy.ts#L42-L47 they are not waiting the tx to be mined as ethers factory.deploy function return a "to be mined" contract if I remember correctly;

Tests

Test scenarious

✓ should send eth_sendRawEthSignTransaction (2778ms)
✓ should sendTransaction (1743ms)
✓ gas price should be 0 (496ms)
✓ should estimate gas (806ms)
✓ should get correct chainid
✓ should get transaction (l2 metadata) (1759ms)
✓ should get block with transactions (524ms)

Output

Example contract call to Proxy__OVM_CanonicalTransactionChain: https://blockscout.com/lukso/l14/tx/0x404115463f303d6205f4c08f280eb5ae295dbfd45eb0c14190b37145e5244e6f/internal-transactions

There are 5 contract calls for every test run. For example one test run is calling:

and then

There are internal transactions between contracts Proxy__OVM_CanonicalTransactionChain and OVM_CanonicalTransactionChain: https://blockscout.com/lukso/l14/address/0x918bc4DA93bF4D3DA00E6e10Bd8e42d00B5d0B09/internal-transactions

Known issues

During integration-tests the batch submitter output was:

batch_submitter_1  | 2020-12-02T14:39:36.648Z error:oe:batch-submitter:init Error submitting batch {"reason":"cannot estimate gas; transaction may fail or may require manual gas limit","code":"UNPREDICTABLE_GAS_LIMIT","error":{"reason":"processing response error","code":"SERVER_ERROR","body":"{\"jsonrpc\":\"2.0\",\"error\":{\"code\":-32016,\"message\":\"The execution failed due to an exception.\",\"data\":\"Reverted\"},\"id\":59}\n","error":{"code":-32016,"data":"Reverted"},"requestBody":"{\"method\":\"eth_estimateGas\",\"params\":[{\"gasPrice\":\"0x3339059800\",\"from\":\"0xb2eb7c9ab57c2187a1bb2dec12f8b8b6d8574388\",\"to\":\"0x918bc4da93bf4d3da00e6e10bd8e42d00b5d0b09\",\"data\":\"0xfacdc5da0000000000000000000000000000000000000000000000000000000005f5e0ff\"}],\"id\":59,\"jsonrpc\":\"2.0\"}","requestMethod":"POST","url":"http://34.78.227.45:8545"},"tx":{"data":"0xfacdc5da0000000000000000000000000000000000000000000000000000000005f5e0ff","to":{},"from":"0xb2Eb7c9aB57C2187A1BB2Dec12F8B8B6d8574388","gasPrice":{},"nonce":{},"gasLimit":{},"chainId":{}}}

It's because 0x918bc4da93bf4d3da00e6e10bd8e42d00b5d0b09 is a contract address and we can't estimate gas there:

curl --location --request POST 'http://34.78.227.45:8545' \
--header 'Content-Type: application/json' \
--data-raw '{
    "jsonrpc": "2.0",
    "method": "eth_estimateGas",
    "params": [
        {
            "gasPrice": "0x3339059800",
            "from": "0xb2eb7c9ab57c2187a1bb2dec12f8b8b6d8574388",
            "to": "0x918bc4da93bf4d3da00e6e10bd8e42d00b5d0b09"
        }
    ],
    "id": 999
}'

And the response is:

{"jsonrpc":"2.0","error":{"code":-32016,"message":"The execution failed due to an exception.","data":"Reverted"},"id":999}

Some fixes

I've setted up the chainId to 420 in integration tests because in the params/config.go there is hardcoded id (HERE).
