Error: unknown account sending transaction to Geth


i am doing simple queries using OZ. It all works fine in Ganache-cli blockchain. But with Geth, it gives “unknown account” error.
Google search shows some old bug in web3 which later got resolved. Has anyone encountered that in OZ?

Hi @prabhat,

What was the simple query that you were running?

I connect to the network using Infura so haven’t run into this issue.

Hello @abcoathup,

I created a contract in OZ using createProxy. This works fine.

const MyContractV0 = Contracts.createFromText( Buffer.from(chain.contr, "base64").toString("ascii") );
const instance = await project.createProxy(MyContractV0);

Afterward, I call the initialize method from a separate function of web3.

    const instance2 = loader.fromArtifactText(Buffer.from(contractTextB4, "base64").toString("ascii"), chain.address);
              const initialValue = await instance2.methods['initialize']
                .apply(null, args)
                .send({ from: address, gas: 6e6, gasPrice: 1e6 });

I suspect that web3 sends an unsigned transaction whereas OZ sends signed one. My address is not added in Geth node. That’s why web3 transaction fails!

Is there a way to send such transactions from OZ?

Solved it. We just had to sign the tx before sending.

encoded = contractInstance.methods.myMethod(params).encodeABI()

var tx = {
    to : myContractAddress,
    data : encoded

web3.eth.accounts.signTransaction(tx, privateKey).then(signed => {
    web3.eth.sendSignedTransaction(signed.rawTransaction).on('receipt', console.log)
