Hello Guys, I'm trying to create a contract with sendRawTransaction
I firstly try to use web3 + hooked-web3-provider + ethereumjs-accounts
on nodejs but i get some Error Invalid sender and some are OK but the transaction stuck in queued txpool, and sometime all it's ok, is just a bit crazy :s
so after that i decide to create the contract by my self.
so i directly inspire from : web3.js/lib/web3/contract.js to write de code behind.
but the result is that ask for much more gas
and when i compare my previous contract and the new one there are completely different
and the new one doesn't work.
so i think i'm very close to solution.
this is my code
// Dependencies
var Web3 = require('web3');
var Tx = require('ethereumjs-tx');
var ContractFactory = require('web3/lib/web3/contract');

this._eth = eth;
this.transactionHash = null;
this.address = address;
this.abi = abi;
};
var encodeConstructorParams = function (abi, params) {
return abi.filter(function (json) {
return json.type === 'constructor' && json.inputs.length === params.length;
}).map(function (json) {
return json.inputs.map(function (input) {
return input.type;
});
}).map(function (types) {
return coder.encodeParams(types, params);
})[0] || '';
};
var addFunctionsToContract = function (contract) {
contract.abi.filter(function (json) {
return json.type === 'function';
}).map(function (json) {
return new SolidityFunction(contract._eth, json, contract.address);
}).forEach(function (f) {
f.attachToContract(contract);
});
};

var events = contract.abi.filter(function (json) {
return json.type === 'event';
});

All.attachToContract(contract);
events.map(function (json) {

});
};

if (count > 50) {
filter.stopWatching();
callbackFired = true;
if (callback)
callback(new Error('Contract transaction couldn\'t be found after 50 blocks'));
else
throw new Error('Contract transaction couldn\'t be found after 50 blocks');
} else {
contract._eth.getTransactionReceipt(contract.transactionHash, function(e, receipt){
if(receipt && !callbackFired) {
contract._eth.getCode(receipt.contractAddress, function(e, code){
/*jshint maxcomplexity: 6 */
if(callbackFired || !code)
return;
filter.stopWatching();
callbackFired = true;
console.log('CODE', code);
if(code.length > 2) {
// console.log('Contract code deployed!');
contract.address = receipt.contractAddress;
// attach events and methods again after we have
addFunctionsToContract(contract);
addEventsToContract(contract);
// call callback for the second time
if(callback)
callback(null, contract);
} else {
if(callback)
callback(new Error('The contract code couldn\'t be stored, please check your gas amount.'));

@fbmx did you eventually solve this? Seems since Homestead, we've been getting invalid sender as well.

I am seeing this "Invalid sender" error (probably thrown here) as well when using https://www.kraken.com/ether/ (based on web3.js) and https://www.myetherwallet.com (may not even seem to use web3.js). Some transactions go through, some not.
Users on reddit mentioning the same error message:
https://www.reddit.com/r/ethereum/comments/4cmzqx/issues_with_recovering_presale/
Seems this error may be caused by some malformed "from" address?
