Describe the Problem

The estimateGas method on the signer (provider) does not include the from field as part of the JSON RPC request body. For example, when trying to estimate gas for a QRC20 deployment, Hardhat returns the error:

npx hardhat run scripts/estimateGasQuais.js --network cyprus1

Result:

Error: json-rpc-provider: cannot estimate gas; transaction may fail or may require manual gas limit [ See: https://links.quais.org/v5-errors-UNPREDICTABLE_GAS_LIMIT ] (reason="execution reverted: ERC20: mint to the zero address", method="estimateGas", transaction={"gasLimit":{"type":"BigNumber","hex":"0x3d0900"},"data":"0x........5d\"}],\"id\":47,\"jsonrpc\":\"2.0\"}","requestMethod":"POST","url":"http://localhost:8610"}, code=UNPREDICTABLE_GAS_LIMIT, version=providers/0.1.0)
  reason: 'execution reverted: ERC20: mint to the zero address',
  code: 'UNPREDICTABLE_GAS_LIMIT',
  method: 'estimateGas',

The equivalent Hardhat script using ethers.js returns an output that indicates that the from field is included in the RPC request body:

npx hardhat run scripts/estimateGasEthers.js --network cyprus1

Result:

Deployment error: Error: processing response error (body="{\"jsonrpc\":\"2.0\",\"id\":45,\"error\":{\"code\":-32000,\"message\":\"address is not in scope\"}}\n", error={"code":-32000}, requestBody="{\"method\":\"quai_estimateGas\",\"params\":[{\"from\":\"0x0b3be7ca8b8948a0f651ac681a4dff39e222d8d3\"}],\"id\":45,\"jsonrpc\":\"2.0\"}", requestMethod="POST", url="http://localhost:8610", code=SERVER_ERROR, version=web/0.1.0)

Code Snippet

const quais = require("quais");
const hre = require("hardhat");

async function main() {
  console.log(`using network ${hre.network.name}, endpoint ${hre.network.config.url}`);
  const ethersContract = await hre.ethers.getContractFactory("QRC20");
  const quaisProvider = new quais.providers.JsonRpcProvider(
    hre.network.config.url
  );

  const walletWithProvider = new quais.Wallet(
    hre.network.config.accounts[0],
    quaisProvider
  );
  await quaisProvider.ready;

  const QuaisContract = new quais.ContractFactory(
    ethersContract.interface.fragments,
    ethersContract.bytecode,
    walletWithProvider
  );
  try {
    const gas = await quaisProvider.estimateGas(
      QuaisContract.getDeployTransaction({ gasLimit: 4000000 }), 
    );
    console.log("Gas estimate:", gas.toString());

  } catch (error) {
    console.error(error);
  }
}

main()
  .then(() => process.exit(0))
  .catch((error) => {
    console.error("Deployment error: ", error);
    process.exit(1);
  });

Contract ABI

This error is reproducible when deploying a QRC20 contract that contains a `_mint` function within the constructor.
