I would like to set a default account for my web3 operations with web3js but it does not work.

I'm using web3@1.0.0-beta.29 and here is my code.

  const Web3 = require('web3')
  const Token = require('./Token.json')

  const web3 = new Web3(new Web3.providers.HttpProvider())//provider.web3
  web3.eth.defaultAccount = '0x4615ff6690a3bb23bd85051c5c69abba4092bbb4'
  const tkn = new web3.eth.Contract(Token.abi, '0xba9d4199fab4f26efe3551d490e3821486f135ba')

  tkn.methods.transfer('0x4615ff6690a3bb23bd85051c5c69abba4092bbb4', 1e9)

the output of this is

    Error: No "from" address specified in neither the given options, nor the default options.

the documentation says that this should not happen

  • If you want to send any tras it should be signed with your private key/password. I couldn't see in your code. – Jitendra Kumar. Balla Feb 3 '18 at 10:47

I ran into the same problem. I had to explicitly specify the address on the send function call, like this:

tkn.methods.transfer('0x4615ff6690a3bb23bd85051c5c69abba4092bbb4', 1e9)
    .send({ from: web3.eth.defaultAccount })

    the point is to set a defaultAccount and not have to specify the from in every send – Micha Roon Feb 3 '18 at 8:12
  • Default account is already set, its just a general value that you can use. – btc4cash Mar 29 '18 at 1:38

When creating the contract instance , you can set the "from" field in the options. Then all your transactions will default to that address. You could give the from address as the default Account.

  • according to the documentation, the default account should be used for that. – Micha Roon Feb 3 '18 at 8:12
  • Please add the link to the documentation that mention that. – btc4cash Mar 29 '18 at 1:38
  • @btc4cash - The docs appear inconsistent. defaultAccount says it should be used if from is missing. However, send does not list from as optional. – Broots Waymb Apr 20 '20 at 0:34

Your correct, but if you want to send any transaction to eth network. That should be signed with your account/unlocked your account.

//unlock your account before call transfer web3.personal.unlockAccount(web3.eth.accounts[1],'abc123');

Or use private key to send information.

    the goal is to have Web3 fill out the FROM automatically. The error has nothing to do with signing – Micha Roon Feb 6 '18 at 22:13
