code snippet :
https://github.com/thelostone-mc/web/blob/rsk/app/assets/v2/js/pages/bounty_detail/rsk_extension.js#L9-L30

to reproduce, head over to gitcoin site and paste this in browser

 const rskHost = "https://public-node.testnet.rsk.co"
  const rskClient = new Web3();
  rskClient.setProvider(
    new rskClient.providers.HttpProvider(rskHost)
  );

to_address="0xbF80163459fd26227970DF1b0b16cB8C846566af"
from_address="0xD6332F76e3911EF876B330F4c5b2367045544B3d"
amount = 0.001 

 const tx_args = {
    to: to_address.toLowerCase(),
    from: from_address.toLowerCase(),
    value: rskClient.utils.toWei(String(amount)),
    gasPrice: '0x3938700',
    gas: rskClient.utils.toHex(318730),
    gasLimit: rskClient.utils.toHex(318730),
    nonce: await rskClient.eth.getTransactionCount(from_address.toLowerCase())
  };
  
  rskClient.eth.sendTransaction(
    tx_args,
    (error, result) => conso.log(error, result)
  );

@thelostone-mc it fails because sendTransaction is a method from personal module and it is not enabled in RSK public nodes (you need to use sendRawTransaction or sendSignedTransaction)

[thelostone-mc]

code to test ERC-20 transfer (tRif)

init connection

  const rskHost = "https://public-node.testnet.rsk.co";
  const rskClient = new Web3();
  rskClient.setProvider(
    new rskClient.providers.HttpProvider(rskHost)
  );

Do transfer

amount = 3.0;
amountInWei  = amount * 1.0 * Math.pow(10, 18);
amountAsString = new rskClient.utils.BN(BigInt(amountInWei)).toString();

to_address = '0xbF80163459fd26227970DF1b0b16cB8C846566af';

// rRif
token_address = ('0x19f64674d8a5b4e652319f5e239efd3bc969a1fe').toLowerCase();

token_contract =new  rskClient.eth.Contract(token_abi, token_address);
     

  data = token_contract.methods.transfer(to_address.toLowerCase(), amountAsString).encodeABI();

  tx_args = {
      to: token_address,
      from: ethereum.selectedAddress,
      value: '0x0',
      gasPrice: rskClient.utils.toHex(await rskClient.eth.getGasPrice()),
      gas: rskClient.utils.toHex(318730),
      gasLimit: rskClient.utils.toHex(318730),
      data: data
    };

await ethereum.request(
      {
        method: 'eth_sendTransaction',
        params: [tx_args],
      }
    );

when user clicks "payout bounty" but doesn't have nifty wallet extension installed or it's disabled

[thelostone-mc]

LGTM

[thelostone-mc]

why does this change ? does this affect the round function that is used in frontend

[chibie]

there's always been an error like object of type Decimal is not JSON serializable while running sync_pending_fulfillments

[thelostone-mc]

Did we check to make sure that does this not have any side affects ? @chibie
