Ethereum: Getting error “Contract-transaction-hash=”” does not match provided contract-tx-hash=””

Ethereum transaction error: Hash contract transaction does not match

As a developer who uses the protocol kit to create, suggest and perform Ethereum transactions through Backend, you have a problem with a specific error message that prevents your application from processing certain types of transactions. Especially when you try to carry out transactions in the Ethereum network for chips such as Matic and Zed, you will receive a mistake in which “the translation of the contract hash = …” does not match the TX-HASH / “…” matches. “.

In this article we will face the details of the problem and examine the potential solutions you help.

What is the -hash transaction?

Before you immerse yourself in the error message, we quickly understand which is a transaction -hash. A transaction -hash (Txhash) is a clear string that represents the hash value of a transaction in the Ethereum network. It is used for different purposes, e.g. B. To verify the integrity of the transaction and track transactions on different block heights.

Hash Contractual Transaction against TX-Hash contract **

To put things in the right light you will find some important differences between the two Hashes:

* Contractual transactions (TXHASH) : This is the hash value of a particular contract or function on the Ethereum blockchain.

* Providing the TX-Hash (TXHASH) contract: this does not refer to the hash value of a transaction that has been proposed or mentioned in a different contract, but not on the current block.

Error message

Given the context of your problem, there seems to be two separate problems:

• The error message shows an inconsistency between the TX-Hash contract provided and TXHASH assigned to a certain transaction.

• You also have problems with transactions for chips such as Matic and Zed.

Potential solutions

To solve this problem, we focus on two potential solutions:

Solution 1: Check for transactions

First, make sure you use the right transaction values ​​-hash. Here are a few steps to check your hashes:

• Make sure you use the same contract address for all transactions.

• Check that the transaction type and the functional call in your code are correctly identified.

• If you use a smart contract or library, check the documentation to make sure the txhash values ​​are generated.

Solution 2: Update the Ethereum Customer Library

Another potential solution is to update your Ethereum customer library so that the latest version is used. This can solve all problems in relation to hash generation or compatibility with the new versions of the protocol kit.

How to update the Customer Library:

• Install the latest version of the Ethereum Customer Library with NPM or Garn.

• Check that you perform a compatible version by checking the documentation for your specific library and the protocol kit.

• Update the code to use the recommended TXhash values.

Diploma

Error message “Contract Transmission-Hash = …” does not match the TX-Hashs / ​​”…” contract is an indication of a problem with the Shather or Ethereum Blockchain transaction itself. The Ethereum -Kunde Library and the revision of your intelligent accuracy contracts should be able to solve this problem and successfully process transactions.
