Wemade Introduces Etherscan-Developed ‘WEMIX Scan’

Wemade, a South Korea-based blockchain developer, has announced the launch of its new block explorer, WEMIX Scan, designed for the WEMIX3.0 Mainnet and testnet. This development is part of the company’s broader efforts in the blockchain space.

The block explorer is a result of Wemade’s collaboration with Etherscan, known for its expertise in blockchain data services. The partnership, initiated in May, also includes plans for a block explorer for the Ethereum layer 2 project ‘Kroma’. The release timeline for the Kroma block explorer remains unspecified.

WEMIX Scan, in its design and functionality, aligns with the standards observed in block explorers of major global blockchains. It offers users access to various data points, including transaction methods, total USD value, top 25 NCP data, and gas fees from tokens listed on platforms such as CMC/CoinGecko.

The introduction of WEMIX Scan took place during Korea Blockchain Week on September 5, 2023. Wemade participated as a sponsor for the IMPACT conference, a segment of the event.

Etherscan, primarily recognized for its Ethereum block explorer, has a track record of developing block explorers for various mainnets and testnets, including Bscscan and Polygonscan.

Wemade’s endeavors in the blockchain domain extend beyond just development. With the gaming industry showing increased interest in blockchain technology, Wemade is exploring avenues to integrate these technologies.

TempleDAO Hacker Moves Stolen Funds to Sanctioned Crypto Mixer Tornado Cash

According to data from block explorer, Etherscan, the attacker of the TempleDAO hack, has moved the funds stolen via the recently sanctioned crypto mixer, Tornado Cash.


This information was first disclosed by blockchain data firm on Sunday, PeckShield. A roughly amount of ETH was seen transferred from an address supposed to be that of the TempleDAO hacker to the Tornado Cash platform. The transaction started with a deposit of 0.1, and ETHoccurred place within hours on Sunday.

Tornado Cash is an Ethereum-based crypto mixer used to anonymize transactions on the Ethereum blockchain. In August, the platform got sanctioned by the United States Treasury Department’s Office of Foreign Assets Control (OFAC).

Declaring that the crypto mixer is mainly associated with high-profile hacks such as the Ronin and Harmony breaches. Specifically, OFAC claimed the crypto mixer benefited North Korea’s Lazarus Group and that the platform has been used to launder hundreds of millions of dollars worth of crypto since its launch.

Last week, TempleDAO, a protocol staking platform, suffered a hack on one of its staking vaults. As seen on Etherscan, the hacker made away with 1,830 ETH, which was roughly $2.3 million at the time. 

Notably, this hack comes amid the rise of cryptocurrency hacks this month. According to new data from Chainanalysis, October 2022 is the month with the most hacking activity ever.

The data averred roughly 11 hacks amounting to $718 million happened this month alone. Chainanalysis stated, “At this rate, 2022 will likely surpass 2021 as the biggest year for hacking on record.”

Last week, trading and lending platform Mango Market suffered an exploit which happened via an oracle price manipulation attack. In addition, on October 6, popular crypto exchange, Binance confirmed a BNB cross-chain bridge hack with Roughly $100 million of Binance Coin (BNB) stolen due to the exploit.

What is Etherscan, and how does it work?

Etherscan is the most trusted tool for navigating through all the public data on the Ethereum blockchain and is sometimes called “Ethplorer.” This data includes transaction data, wallet addresses, smart contracts and much more. The application is self-contained and is neither sponsored nor administered by the Ethereum Foundation, which is a non-profit organization.

The team behind Etherscan includes seasoned developers and industry professionals, who developed the Etherscan app to make the Ethereum blockchain more accessible to everyday users.

Although Etherscan is a centralized platform, the app does make it easier for people to search through the Ethereum blockchain.

Is Etherscan a wallet?

Etherscan is not an Ethereum wallet, nor is it a wallet service provider. Users don’t receive an Etherscan wallet when they search the Ethereum blockchain on Etherscan.

Etherscan.io is an independent Ethereum-based block explorer. The Etherscan app keeps track of blockchain transactions on the Ethereum network. The app then displays the results like a search engine.

This allows users to find the details of transactions on the Ethereum blockchain, which may give someone peace of mind if their transferred funds have not yet appeared in their wallet.

While Etherscan can track the activity on an Ethereum wallet address, users will need to link the app to an existing crypto wallet to do so.

You may wonder — Is Etherscan free to use? Yes, Etherscan is completely free.

What is Etherscan used for?

Etherscan allows users to view the assets held on any public Ethereum wallet address. Using Etherscan, enter any Ethereum address into the search box to see the current balance and transaction history of the wallet under consideration. Etherscan will also display any gas fees and smart contracts involving that address.

Users can use Etherscan to:

  • Calculate Ethereum gas fees with the Etherscan gas tracker
  • Lookup and verify smart contracts
  • View the crypto assets held in or associated with a public wallet address
  • Observe live transactions taking place on the Ethereum blockchain
  • Lookup a single transaction made from any Ethereum wallet
  • Discover which smart contracts have a verified source code and security audit
  • Keep track of how many smart contracts a user has authorized with their wallet
  • Review and revoke access to a wallet for any decentralized applications (DApps)

Users can view any transaction of the Ethereum blockchain on Etherscan. These transactions include failed and pending transactions.

Etherscan can also keep track of the progress of an incoming transfer. One way to track a transaction using Etherscan is to look it up on Etherscan.io using its hash key. The hash provides users with an estimate of how long the transaction will take to confirm. The page refreshes once the transaction is complete.

Etherscan also works as an analytics platform. Anyone can use Etherscan to analyze on-chain metrics like changes to Ether (ETH) gas costs, as well as keep track of their portfolio and monitor their transaction history for suspicious activity.

Only information that is public on the Ethereum blockchain is displayed on Etherscan, so information like a user’s private keys can’t be viewed on the app. Etherscan doesn’t store any private keys and is not involved in any of the transactions shown. The app also cannot be used to solve a transaction failure.

Do users need an account to use Etherscan?

Users are not required to sign up for an account before using the Etherscan app. However, signing up for an Etherscan account does give users access to additional features. These features include the ability to track addresses and receive notifications whenever a transaction occurs. Developers may also sign up to gain free access to Etherscan’s blockchain explorer data and application programming interfaces (APIs).

Thus, users with accounts can add their addresses to the “watch list” on the block explorer to monitor or track their investments. Users can also set alerts so that they’re notified of every incoming transaction via email. Etherscan also provides API services for developers so that they can create decentralized applications.

Etherscan provides the following information for all incoming and outgoing transactions:

  • Transaction hash
  • Number of blocks within which the transaction was recorded and the time at which the transaction was confirmed
  • Sender and receiver addresses
  • Gas fee
  • Amount sent
  • Total transaction fee

How does Etherscan work?

To use Etherscan, simply enter any public Ethereum wallet address into the search field at the top of the Etherscan.io homepage. Doing so will allow users to view all the transactions associated with that address.

Viewing a transaction and wallet on Etherscan

Exploring a wallet address on Etherscan under the “Transactions” tab will show a list of all ETH transactions (Txns), or transactions that have used gas (Gwei) associated with that specific wallet.

Type the wallet address on Etherscan’s homepage and click “Search” to be redirected to a page that displays all of that wallet’s information. The data will include its ETH balance and its value denominated in United States dollar, as well as an overview of the wallet’s transaction history.

Click on the wallet’s Transactions tab, which will open up a new page displaying details on all the transactions involving that address. Details include the transaction ID, block height and when the transaction was confirmed.

The block height refers to the block in which the transaction was included. The sender and recipient addresses and the total transaction fee are shown as well.

To explore and track a single transaction, users will need the transaction hash or transaction ID, or TxHash. A TxHash is a unique string of numbers that identifies a transaction on the blockchain.

When users input the TxHash into the Etherscan search bar, a list of information on that transaction will be populated on the page. From here, users can go to the Transactions tab to review additional information about the said transaction. Such data includes whether the transaction status was successful, pending or failed, as well as the total amount that was transferred.

The value of the transaction in ETH, as well as the USD value of ETH at the time of the transaction, can also be viewed. Etherscan also displays the timestamp for each transaction in addition to the transaction cost, denominated in USD.

How to use the Etherscan gas tracker?

“Gas” refers to the transaction fee associated with a transaction to be executed successfully on the Ethereum blockchain. Transaction costs on Ethereum are referred to as gas fees.

Ethereum’s network can get highly congested. When a considerable amount of traffic is running on Ethereum’s blockchain due to Ethereum’s auction-based model, the average gas price goes up as users compete against one another and bid to have their transactions included in the next block. Consequently, transactions are delayed and some transactions fail.

Gas prices vary depending on the block that the user transaction has been included in, as well as the degree of network congestion. Moreover, users may not be able to discern an accurate estimate of the gas fees they’ll be required to pay before initiating a transaction.

To determine a transaction’s gas fees with accuracy, it’s best to use Etherscan’s gas tracker. Etherscan’s gas tracker does more than simply show users the difference in gas prices at various time intervals. It’s also useful for estimating how congested the network is and what the transaction cost will be per transaction.

The Etherscan gas tracker functions as an ETH gas calculator. It examines pending transactions on the Ethereum blockchain to determine how much gas a transaction will require.

Users receive a gas fee estimate so they can adjust the timing of their transactions to avoid high network traffic. Doing so saves transaction costs and allows for cheaper and smoother transactions, without suffering the anxiety that comes with not knowing whether a transaction will fail or succeed.

How to use Etherscan to check the wallet balance and history?

To see how the balance in a user’s wallet has changed over time, look up the address of the wallet on Etherscan and select “Analytics.” From here, users can see the data analytics of a user’s wallet, such as the user’s ETH balance, the entire transfer history, transactions and fees paid.

Using Etherscan to review smart contracts and wallet access

Smart contracts can be read and edited without the need for special permissions by using the Etherscan app’s “Read Contract” and “Write Contract” features. These tabs provide real-time information on various tokens and smart contracts. Users may also use these features to initiate a token transfer and approve smart contract transactions.

Removing a token’s access to the user’s wallet can be achieved using Etherscan’s Token Approval Checker. When users interact with DApps to buy or swap tokens, they tap directly into a user’s wallet with their permission. Therefore, DApps are an appealing target for scammers looking to gain access to users’ Ethereum wallet addresses.

If users see suspicious activity or believe that a DApp has been compromised, they can use Etherscan to revoke its access to a specific wallet address. The user’s assets inside the wallet will not be lost, but users will need to reauthorize the tokens when they access the DApp the next time around.

To use Etherscan to review a user’s approved token list, look up the user’s wallet address on Etherscan’s Token Approval Checker. Doing so will provide users with a list of all approved smart contract interactions with that wallet. From there, users can connect their wallet to Etherscan and click “revoke” to ensure that the specific DApp no longer has access to the user’s wallet.

The road ahead

Etherscan is one of the leading tools for accessing reliable Ethereum blockchain data. Etherscan can review smart contract code, track gas prices and monitor the Ethereum blockchain in real time.

Finally, Etherscan is free and doesn’t require a user to register to access all of its features. Overall, it’s a great place to start for users who would like to learn the full range of functionalities of a blockchain, as well as their Ethereum wallet and what information they can garner from a blockchain explorer.

Etherescan adds new messaging feature for anons: ‘Blockscan Chat’

The team behind the popular blockchain explorer and analytics platform Etherscan has launched an Ethereum-based wallet-to-wallet instant messaging service dubbed “Blockscan Chat.”

Blockscan is currently in beta testing mode, and it currently enables users to engage in an instant wallet-to-wallet chat, access chats from multiple devices, block spammy or unwanted addresses and get notified on the block explorer when a message has been received.

While the new feature is a great way to talk to other anons — say to negotiate an anonymous purchase — it might come in particularly handy for dealing with whitehat hackers, who have often left messages embedded in Ethereum transactions to communicate with individuals and exploited crypto platforms.

Last week’s Multichain hack, which saw a supposed whitehat hacker return 322 Ether (but keep a hefty finder’s fee) and the $610 million PolyNetwork from last year both involved anon discussion via Ethereum transactions as part of negotiations between the culprit and victims.

Etherescan subtly unveiled the new feature via a Jan. 26 tweet that read “wonder what this is for…?” with a screenshot depicting messenger notifications on the platform.

Apart from pleading with hackers to return funds for a bounty, such as the service could be helpful in the NFT market.

Twitter user “bdmartino” argued that the feature could be utilized for the negotiations of NFTs purchases between buyers and sellers, adding that if the transaction was conducted by a decentralized exchange both parties could reduce the fees associated with NFT platforms such as OpenSea.

In terms of user privacy and data storage, Blockscan notes that its information is stored via “global hosting providers” with servers across multiple regions, with inactive data deleted after 24 months.

It also states that the information will not be traded to third parties, but will be disclosed or transferred to partnered parties such as data warehouses, IT service providers and data analytics agencies.

According to its terms of service any user who violates its acceptable use policies such as providing false, inaccurate or misleading information may be barred from a portion of, or all of Blockscan and Etherscan’s related services.
