Transaction Testing in Crypto: Why You Should Verify Your Blockchain Transactions


If moving large amounts of cryptocurrency makes your palms sweat, test transactions can put your mind at ease. Sending a small amount of Bitcoin (BTC) or Ethereum (ETH) as a tester can protect you from Headline poisoning scams And help you keep your digital currencies safe and secure on the blockchain.

Test transactions are a great way to learn more about blockchain technology and see how certain smart contracts work. If used effectively, they also help you detect sandwich bots and protect you from other nefarious actors.

What are test coefficients? Why are some of the brightest cryptocurrency minds using it, and is there any reason why they shouldn’t?

What is the test treatment?

If you deposit or withdraw cryptocurrencies such as Bitcoin or… Ethereum In one of the exchanges, you’re probably familiar with this kind of warning:

The thought of losing everything due to incorrectly entering a wallet address or a complex network is definitely scary. Fortunately, sending a small test transaction through the blockchain system alleviates these concerns. until Vitalik ButerinThe founder of the Ethereum blockchain often uses test transactions before sending large sums.

As the name suggests, these transactions are a simple test tool to ensure that your funds are received by the indicated crypto wallet or exchange. It is a way to verify that the public blockchain network or distributed ledger is working properly. The test parameters confirm that you did not put the wrong address when transferring your cipher.

Why should I use Transactional Testing?

Test transactions put your mind at ease. Whether it’s a simple cryptographic transfer, testing a smart contract, or trying out different types of block chains, test transactions allow you to confirm that everything is working as it should.

While some might say it’s a waste of money or time, the fact that a simple test can save you thousands is worth remembering. If you accidentally entered the wrong address, would you rather send one dollar to the lucky recipient or all you have?

Young testers aren’t limited to transfers alone. Unfortunately, there is no shortage of scammers in the crypto space. Some of the DeFi Wild West blockchain implementations are specifically designed to catch unwary users.

What can tested transactions protect me from?

Despite the prevalence of bad actors trying to scam you out of your hard-earned crypto, most scams can be caught and avoided through test transactions. To help you stay safe out there, here are some common examples:

Poisoning treatment

Address poisoning is a technique where scammers send a $0 transaction to your wallet using an address that has the same first and last characters as yours. Scammers hope that you don’t double-check small details, such as your entire wallet address, before sending money and that you mistakenly copy their address instead of yours.

Test parameters make address poisoning easily avoidable. If your transfer was received correctly at the intended address, you know you did not inadvertently enter a fake address.

sandwich attacks

While sandwich attacks are not technically a scam, they take advantage of user carelessness in the ecosystem and can be avoided with a test transaction. In short, sandwich attacks are performed by Ethereum miners when new blocks are created.

By changing the order of transactions in a new block, the MEV (Mineable Mining Value) bots can run token trades on the decentralized exchange and weed out the buyers instantly.

For example, I buy a $1,000 token. In one block, the MEV bot could buy $10,000 worth of the same token and pump my purchase price, only to get back to me right away.

Some blockchain-based token contracts are designed with purely evil intentions. Another typical DeFi scam, a magnet, is a token that cannot be sold. Like a mouse in a bowl of honey, you can get in, but you can’t get out.

Instead of buying these awful tokens outright, demo trading to verify that you can actually sell after you buy can save you a lot of money in the long run.

Loss of funds

Since your favorite cryptocurrency exchange undoubtedly tells you every time you transfer, your money could be lost forever if you entered the wrong address.

Why take the risk? One test transaction can save you a life of regret.

Test Transactions – Not to be confused with Testnet

While test transactions are used to test specific functions on the blockchain, it is not the same as the testnet blockchain. A testnet is a specific test environment with “free” code where developers can experiment with different code and algorithms.

Testnets, such as Ethereum Goerli or ribbed Mumbai, used for different types of tests. This can include smart contract testing, load testing, or security testing. In some cases, blockchain developers may invite their community to test certain features of a network or application in return for a token reward.

In late 2022, Aptos test networks received 300 APT tokens as a reward for testing features on the network, such as NFT and node testing.

Transactional testing in crypto – pros and cons

There are many reasons why transaction backtesting is a great tool that keeps your money safe in the world of web 3. Of course, in order to be objective, it is important to realize that it is not foolproof and has its (minor) drawbacks.


  • Test transactions help you spot avoidable scams, such as headline poisoning and attraction sites that can trick you out of your money.
  • Test transactions ensure that your crypto goes to the correct address and network when transferring funds.
  • Test transactions can help you learn about new blockchain networks and applications, and experimental crypto use cases.
  • Joining incentive test networks can make you eligible for a major airdrop.


  • Submitting a test transaction before your main transaction means that you will need to pay the fee twice. While this is not an issue with affordable networks like Polygon or Solana, it can get quite expensive during Ethereum congestion.
  • Test transactions take time to process. If you need to transfer money quickly, sending a tester can slow you down. However, it won’t take more than a few minutes and can save you a lot of money.

on the flip side

  • Testing transactions is a security measure that requires constant attention. Just because your test transaction worked the first time doesn’t guarantee that the same transfer will work a few months later. As Metamask says, “continuous checking” is usually a value in the crypto space.

Why should you bother

Test transactions are simple and affordable. Although it may seem unnecessary at times, test transactions can save you money and protect you from scams in the Web3 world.

questions and answers

How do I verify crypto transactions?

You can check the status of crypto transactions using a blockchain explorer such as Etherscan or Simply copy the transaction ID into the field provided to verify the transaction and any associated information.

Can you recover lost money in crypto?

In general, it is difficult to recover lost crypto money. Unless you have some way to contact the owner of the received wallet, you are unlikely to ever see the lost funds again.

What happens if I send encryption to the wrong network?

If you have sent crypto to the wrong network, you can still access it by adding the network to a compatible wallet. Cryptocurrency wallets like Rabby conveniently have most of the blockchain networks pre-installed, making it easy to move misplaced funds around.
