How to find a specific transaction in the blockchain?

Transactions, their types and everything you need to know to conduct an investigation.

Often, when contacting law enforcement or an exchange, authorized personnel may request transaction hashes. Often, this can become a problem, since not every user knows where to find the transaction hash, why it is needed and where it can be used.
Using Explorer to search for a transaction
A transaction in a blockchain is a hashed record of the interaction between two counterparties. Transactions on the blockchain cannot be canceled or changed once they are signed (confirmed).
To search for a transaction you will need to use explorers. You can find the main list of blockchain explorers here. We also wrote in more detail about explorers in this article.

Let’s give an example based on one of the most popular explorers Etherscan (Ethereum network):
We need to open the site
Fingerprint or sometimes Footprint is a complete digital fingerprint of the device, consisting of information about your operating system, settings, active browsers, installed plugins, etc.
If we know the hash of the transaction, we simply type it into this search box and find out additional data about the transaction. Additional data can include information about the block in which the transaction was confirmed, information about commissions. Especially useful will be additional information about where the tokens went if the counterparties of the transaction include a smart contract.
If we don’t know the transaction hash, we can type in the address that participated in this transaction and try to search for the required transaction hash by hand. The transaction hash will be recorded in the first column of the table, whether it is the Transactions tab or the Token Transactions tab (we wrote more about the difference between the two tabs in this FAQ).

Types of transactions
The main categories of transactions are as follows:
Transactions initiated by external addresses. External addresses can be considered as counterparty wallets.
Internal Transactions
Transactions initiated by internal addresses. Typically, internal transactions are transactions initiated by smart contracts.
ERC-20 Transactions
The ERC-20 Transactions table shows all transactions that the ERC-20 token was involved in. For example, USDT or USDC token on the Ethereum network will be classified here.
ERC-721 Transactions
Similar to the ERC-20 Transactions table, ERC-721 Transactions shows all transactions using ERC-721 tokens. ERC-721 is a non-fungible token, that is, an NFT.

Transaction risk scoring

→ The Risk Score of an address in cryptocurrency is a score that determines the degree of risk associated with a particular address on the blockchain.

This risk may be that the address belongs to fraudsters, is used for illegal transactions, or is associated with other negative factors. An address’s Risk Score can be used to assess the security of transactions and decide whether an address is worth working with.

The Risk Score of an address displays the risk score of the address.
→ The Risk Score of a cryptocurrency transaction is a metric that determines the degree of risk associated with a particular transaction on a blockchain.

This risk may be that the transaction is fraudulent or illegal, or related to other negative factors. A transaction’s Risk Score can be used to assess the security of transactions and to decide whether or not a transaction is worth pursuing.

The Risk Score of a transaction displays the amount of illegal funds included in the transaction volume.

Every address on the blockchain has a Risk Score, which implies that every transaction also has a Risk Score.
Before conducting a transaction with a co-trader, we suggest you check the Risk Score of their address. If this score is within the normal range (up to 69% on average, but the closer to the maximum value, the worse) you can exchange tokens without worrying about their blocking by VASP.

After interacting with the counterparty, you can check the Risk Score of the transaction. In most cases, if the Risk Score of the counterparty has been checked and no serious risks have been identified, the Risk Score of the transaction will not exceed the norm.

To find out the Risk Score of your address and your counterparties, you can use our tool Btrace.

A certain address has laundered funds to addresses 0x01.11 (coincidences are random). Address 0x01.11 had 100 ETH clean and added 100 USDT dirty.

Next, this address offers you an exchange in which it will give you 100 USDT. In this case: The Risk Score of his address may be within the normal range (since 100 ETH is much larger than 100 USDT), but the Risk Score of the transaction will be 100 (since 100 USDT has a higher Risk Score).

Thus, knowing his contact information, you can apply to law enforcement authorities with a fraud report.
Check blockchain address using Btrace
In seconds, determine the risk level of the counterparty’s address, find out the source of his funds and make an informed decision about interacting with him.
