How To Know If A Transaction Went Through Or Not? (out Of Gas)

How To Know If A Transaction Went Through Or Not? (out Of Gas)

How to know if a transaction went through or not? (out of gas) Apparently when sending transactions from an Account instead of a Wallet, the gas spent is small (21K), and not enough to send ether to a Contract Wallet (out of gas, so to speak). When this happens, the transaction shouldn't go through (or be cancelled, as it says here ), however it seems to still be recorded in the blockchain, why? Example . Doesn't EtherScan.IO provide any clue about if the transaction ended up being valid or not? In this case it should be marked as CANCELLED/INVALID in that URL, as far as I understand. ok thanks, BTW is there a way to know this status via RPC? should I open a new question about this or is there already one? knocte Feb 9 '16 at 6:03 It might be similar to this question ethereum.stackexchange.com/q/1181/42 ? RPC eth_getTransactionReceipt and checking the gas used is a good way to find out. Sorry I won't flag if you open a new question. eth Feb 9 '16 at 6:07 In etherscan, look for the TxReceipt Status which will have Fail in red, or Success in green. Example of a failure: eth.getTransactionReceipt(transactionHash) will return a status field that has a value of 0 when a transaction has failed and 1 when the transaction has succeeded. Here's an example showing the status field: { blockHash: '0xb1fcff633029ee18ab6482b58ff8b6e95dd7c82a954c852157152a7a6d32785e', blockNumber: 4370000, contractAddress: null, cumulativeGasUsed: 21000, gasUsed: 21000, logs: [], logsBloom: '0x000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 Continue reading >>

Checking Or Replacing A Tx After It's Been Sent

Checking Or Replacing A Tx After It's Been Sent

Our Check TX Status Page via TX hash: Can I cancel, override, overwrite, replace, or do anything once a transaction has been sent? 99.9999999999999999% of the time the answer is NO. Once a transaction has been mined and is included in a block on the blockchain, it cannot be canceled or replaced. During times of normal volume, transactions are mined within seconds and do not spend any length of time in the transaction pool. There is simply not enough time to cancel or replace or override a transaction once it has been sent. During times of extremely high volume (like we've seen during the Bancor and Status Token Contribution periods), transactions could be pending for hours, if not days, before being mined. During these times it is theoretically possible to replace an existing transaction with a new transaction with a higher gas price. The second transaction, theoretically, will be mined before the first transaction, effectively "canceling" the first transaction. The easiest way to do this is by sending a 0 ETH transaction to your own address with the same nonce and higher gas price. This will "cancel" your first transaction. There is no guarantee this will work, nor that it will work every time. This tool is very, very new. Please use at your own risk. Do not take this article or features on MyEtherWallet as an indication that you can cancel a transaction you accidentally sent to the wrong address, or get your ETH back once it has been sent. It is only regarding finding, checking, and potentially replacing transactions that have been stuck in the transaction pool for very long period of time. Copy & paste the transaction hash into the field provided. Details will appear depending on the state of the transaction. It could be...

Life Cycle Of An Ethereum Transaction

Life Cycle Of An Ethereum Transaction

Learn How an Ethereum Transaction is Created and Propagated to theNetwork Transactions are at the heart of the Ethereum blockchain (or any blockchain for that matter). When you interact with the Ethereum blockchain, you are executing transactions and updating its state. Have you ever wondered what exactly happens when you execute a transaction in Ethereum? Lets try to understand it by looking at an example transaction. In this post, we will cover the following. An end to end traversal of an Ethereum transaction starting from your browser/console to the Ethereum network and back to your browser/console Understand how transactions work when you use a plugin such as Metamask or Myetherwallet instead of running your own node What to do if you are too paranoid and dont trust any plugins to execute your transaction? This post assumes that you have a basic understanding of Ethereum and its components such as accounts, gas and contracts. Here is a good explanation of these concepts. If you are a developer new to Ethereum, you might find this helpful. You can also learn to build a simple dapp here . This post will make more sense if you have executed few transactions yourself. An example of a transaction is you sending some ether to another person or a contract. Another example is if you have interacted with a dapp. For example, if you go here and buy some tokens, that would be a transaction. If you vote for a candidate, that would be another transaction. 1. End to end overview of an Ethereum transaction Lets take the following contract call as an example and traverse through the entire flow of how this function call/transaction gets executed and gets permanently stored on the blockchain. You can find the entire contract here . At a high level, its a voting contract where you i Continue reading >>

How To Verify Transactions On The Blockchain

How To Verify Transactions On The Blockchain

Blockchain & Crypto > Crypto-Investing 101 > How to Verify Transactions How to Verify Transactions on the Blockchain I trust you already have an understanding about the concept of blockchain and how it works? If you haven't, read about blockchain and cryptocurrency here . Essentially with a blockchain, exact copies of transaction records (ledger / database) are distributed across the network. The ledger is transparent for anyone to view, so you can actually verify the progress and get confirmation of your transactions yourself. A good blockchain would have a strong developer and community support. They also should have a number of public blockchain explorer websites, either built by the official blockchain team or by the community. Using Ethereum as an example, you can use Etherscan.io to explore the Ethereum blockchain. Here are some more examples: Bitcoin blockhain explorer: Blockchain.info . A blockchain explorer website usually has a search function. Here, you should be able to search for: An address: To find out more details about the address, for example the balance, and transactions that has been done by that address. A transaction hash (transaction ID): To verify whether a transaction has been completed, and to check how many blocks has confirmed it - since blockchain is a string of blocks that contain all previous transactions. If you visit the Etherscan.io website , you can see the latest transactions that went through the blockchain. Let's take a random transaction for our example here: Transaction ID: Parameter after the "/tx/". Which block number this transaction occurred on. How many blocks have confirmed the transaction. Timestamp: When the transaction happened (date, time, and timezone). Address of the sender: In this case 0xf1f5a00f88542b835df57298d496 Continue reading >>

How Do Bitcoin Transactions Work? - Coindesk

How Do Bitcoin Transactions Work? - Coindesk

Bitcoin transactions are sent from and to electronic bitcoin wallets , and are digitally signed for security. Everyone on the network knows about a transaction, and the history of a transaction can be traced back to the point where the bitcoins were produced. Holding onto bitcoins is great if you’re a speculator waiting for the price to go up, but the whole point of this currency is to spend it, right? So, when spending bitcoins, how do transactions work? There are no bitcoins, only records of bitcoin transactions Here’s the funny thing about bitcoins: they don’t exist anywhere, even on a hard drive. We talk about someone having bitcoins, but when you look at a particular bitcoin address, there are no digital bitcoins held in it, in the same way that you might hold pounds or dollars in a bank account. You cannot point to a physical object, or even a digital file, and say “this is a bitcoin”. Instead, there are only records of transactions between different addresses, with balances that increase and decrease. Every transaction that ever took place is stored in a vast public ledger called the block chain. If you want to work out the balance of any bitcoin address, the information isn’t held at that address; you must reconstruct it by looking at the blockchain. If Alice sends some bitcoins to Bob, that transaction will have three pieces of information: An input. This is a record of which bitcoin address was used to send the bitcoins to Alice in the first place (she received them from her friend, Eve). An amount. This is the amount of bitcoins that Alice is sending to Bob. An output. This is Bob's bitcoin address. To send bitcoins, you need two things: a bitcoin address and a private key. A bitcoin address is generated randomly, and is simply a sequence of lett Continue reading >>

How To Do An Ethereum Transaction, & Check Your Balance? | Cryptocompare.com

How to make an Ethereum Transaction, & check your balance? Once you have managed to set up an Ethereum Miner using either your GPU or your CPU its time to start checking your balance and start trading. Were going to show you how you can check your balance in Command Prompt, how to convert between all the different values of Ether , such as the base unit Wei, and how to make your first transaction! Once you have set up your miner via running the Geth program and Ethminer program (see our guide here on how to get started), you need to open up a third Command Prompt Window. Step 1: This can be done by right clicking on the command prompt in the taskbar at the bottom of your screen and then clicking on the command prompt that appears at the top of the menu. A third command prompt should now be open. Step 2: You now need to tell this Command Prompt where to look to get up and running. Usually the command Prompt window opens looking at your user profile. If this is the case you need to tell Command Prompt to go to wherever you installed geth. In our guide we installed it straight on the C Drive so we need to tell command prompt to get back to the C Drive which we do by typing in cd C:\ and pressing enter. Step 3: You then need to tell Command Prompt what to do. In this case you need to tell it to attach to Geth. So all you type in is geth attach which should look like this C:/>geth attach and then press enter. You now have a console up and running talking to geth so you can start asking it questions or telling it to do things. Remember for"geth attach" to work you need to have anotherCommand Prompt Window runningwith "geth --rpc". If you want to find out your address you type in eth.coinbase. This should look like this C:/>eth.coinbase. Press enter and you should see your ad Continue reading >>

Eth Blockchain Congestion

Eth Blockchain Congestion

Modified on: Fri, 17 Nov, 2017 at 3:01 AM At times, if there is blockchain congestion on the Ethereum network, we may manually disable the ETH wallet as a precaution to prevent new transactions from being sent to a congested network, that may lead to orphaned transactions. This is a provisional and temporary measure; once the congestion on the Ethereum network has cleared, the wallet will be re-enabled. Ethereum blockchain congestion is a global issue which can occur. Usually, this takes place when there is a crowdfund and individuals rush to send their coins, increasing the gas price of all transactions on the network. This flood of traffic leads to wallets, such as that on CoinExchange.io, that receive heavy loads of traffic to experience a delay in processing time. In the event you have sent a transaction and then notice this error on the wallet, please be patient and do not be alarmed. The wallet will re-enable to normal functioning status. Your transaction should be in the global Ethereum transaction pool and will get identified and confirmed by the network once active again. What do I do if I have waited an hour or more for ETH related transaction to process ? Please head to one of the Ethereum block explorers listed below and search the transaction id. If the transaction cannot be found in the block explorer it may have be orphaned. If this is the case, please submit a support ticket and included the following information. Continue reading >>

How To Read An Ethereum Transaction

How To Read An Ethereum Transaction

Last updated on October 30th, 2017 at 08:01 am Although 99Bitcoins has been around for a while, it just occurred to me that weve never really covered the basics of Ethereum transactions even though weve discussed Ethereum itself. So this post is aimed at all of the Ethereum newbies out there: lets understand how to read an Ethereum transaction. The first thing youre going to need in orderto read a transaction is an Ethereum block explorer. A block explorer is a search engine that allows you to search inside the Ethereum blockchain for transactions, addresses, and other interesting information. In this case, well use EtherScan , one of the most popular Ethereum block explorers out there today. Lets take a look at a random Ether transaction via EtherScan. Now lets break down the data that are displayed: TxHash Also known as the transaction ID, TxHash is a way to look up a specific transaction on the Ethereum blockchain. Block Height The block number in which the transaction was included (for an in-depth explanation of blocks, watch this video ) Time Stamp The time the transaction entered the blockchain (i.e., the time the block was mined) From/To The sending and receiving Ethereum addresses Value How much Ether was sent and the equivalentUSD value Before we move to the rest of the terms, lets look at a short explanation of gas. Gas in Ethereum is somewhat similar to transaction fees in Bitcoin . Each operation on the Ethereum network requires a fixed amount of gas (adding two numbers costs 3 gas, calculating a hash costs 30 gas, and sending a transaction costs 21,000 gas, for example). Gas is paid in Ether, but you cant own gas. Its just calculated at a fixed gas/ether exchange rate when you send a transaction on the Ethereum blockchain. Well talk more about gas in a dif Continue reading >>

Inside An Ethereum Transaction

Inside An Ethereum Transaction

CodeTract is a startup focused on building smart contracts enforced by blockchains Ethereum can be thought of as a transaction based state machine, where transactions can change the state and the state keeps track of interactions. Here we examine at a high level, the constituents of a transaction and explain how most of the gibberish hex values are determined. We will be using nodejs in this tutorial so we start off by installing the dependencies. $ npm install [email protected] [email protected] [email protected] Then creating a file tx.js and requiring the dependencies. var web3 = new Web3(new Web3.providers.HttpProvider(' )); First we start with a private key. Ethereum uses public key cryptography for authentication. More specifically, Elliptic Curve Digital Signature Algorithm (ECDSA) with secp256k1s curve is used. The private key is just a random 256 bit data except for some restrictions . For example var privateKey = '0xc0dec0dec0dec0dec0dec0dec0dec0dec0dec0dec0dec0dec0dec0dec0dec0de'; var publicKey = util.bufferToHex(util.privateToPublic(privateKey)); and you should get the following if you print out publicKey 0x4643bb6b393ac20a6175c713175734a72517c63d6f73a3ca90a15356f2e967da03d16431441c61ac69aeabb7937d333829d9da50431ff6af38536aa262497b27 The Ethereum address associated with this private key is the last 160 bit of the SHA3256 (Keccak) hash of the public key. var address = '0x' + util.bufferToHex(util.sha3(publicKey)).slice(26); //0x53ae893e4b22d707943299a8d0c844df0e3d5557 As you can observe, it is actually possible for multiple private keys to have the same address. An Ethereum account is associated with each address and each have the following attributes nonce the count of the number of outgoing transactions, starting with 0 balance the amount of ether in the account Continue reading >>

How To Find An Ethereum Transaction On The Blockchain

How To Find An Ethereum Transaction On The Blockchain

How To Find An Ethereum Transaction On The Blockchain By The 'Stache on Wednesday, February 14, 2018 After being in crypto for a while you start to take some very simple (yet really very complex things) for granted. I have spent thousands and thousands of hours reading, researching, testing, writing, and talking about cryptocurrency and that has allowed me to find a ton of great stuff to share with all my followers. Sometimes I take for granted the very simple things that we learned when we first started out and I tend to forget that others need this very basic guidance as well. Even something as simple as finding your transaction on the Ethereum blockchain is a hurdle that any beginner or newcomer will have to jump at some point. If you are new to Ethereum (the #2 cryptocurrency at the moment) then being able to simply find your transaction on the blockchain may be a bit of a puzzle. Of course, if you still need to brush up on what Ethereum is, then you can read my previous article that goes over Ethereum basics . Anytime you make a transaction using Ethereum (or most blockchain projects) you will get a transaction hash (transaction ID or "TxID") that represents your transaction on the Ethereum Blockchain. Typically the TxID is a long string of hash-generated numbers and that won't really make any sense to you, but it is how blockchain transactions are represented. Ethereum transaction ID's look like this: 0x83ceaf1ec0da55c3de474578b1513ccdbcdee43a4c28f52f44150aafb0cc5d9b Most sites like Coinbase or Binance will show you this transaction ID right after you make your transaction and the numbers are typically a link to full transaction details hosted off site on one of the popular "block explorer" websites. Of course, you can always just copy the transaction ID and past Continue reading >>

Deposit Does Not Arrive

Deposit Does Not Arrive

The exchange I am sending to Binance from shows that my transaction completed, why havent I received anything on Binance? A withdrawal marked as completed or success on an exchange does not mean that the transaction has fully processed to the receiving exchange it simply means that the transaction was successfully posted to the blockchain. Once a transaction is on the blockchain, it will still take a variable amount of time to confirm and post to the destination exchange. Different blockchains require different amounts of confirmations before a transaction is verified. It is not uncommon for a blockchain to be congested with many transactions, causing unexpected/unusual delays in processing your transaction. You may use the transaction ID (TxID) to follow the status on the blockchain. If your transaction shows unconfirmed on its blockchain, this is beyond our control. You must wait for the transaction to be processed on the blockchain. Once it is included in the blockchain, it will begin to produce confirmations. For Bitcoin and Bitcoin-based projects, your transaction should arrive on Binance by 2 confirmations. For Ethereum and most other projects (quicker to confirm), it should arrive by 30 confirmations. If you have sent to Binance from another exchange but not received a TxID, please contact customer service for that exchange. Noted: If the transaction is confirmed by Blockchain but not be credited to your binance account, please reopen original ticket and attached: Blockchain explorer sceenshot with the confirmed transaction; your account balances Screenshot missed the transaction; Well try best to solve it as soon as possible.By the way,priority would be low if tickets lack of above screenshots. 1) How do I check the transaction status on the Bitcoin blockchain?
