Magic Eden to Trial ME Token and Its Asking Users Not to Trade It – Decrypt

Magic Eden to Trial ME Token and Its Asking Users Not to Trade It – Decrypt



Magic Eden may want users to claim a token called TestME Tuesday using its digital wallet—but the NFT marketplace is encouraging degens to sit this one out.

That’s because the TestME token, as the name implies, is intended to be a trial run and precursor to the Magic Eden Foundation’s governance token. That token, rebranded as ME earlier this year, has yet to be assigned a specific release date.

The Magic Eden Foundation will release the bare-bones token on Tuesday as a way for its associated NFT marketplace to flex its technical muscles. Though the company is encouraging users to claim the token if they can, it’s also cautioning users against speculating on what’s intended to be a one-off showcase.

The token won’t serve as the cross-chain NFT marketplace’s governance token, which was initially teased in January. Rather, the endeavor is being billed as a test run for Magic Eden Wallet, which will be used when the governance token is released later.

The cross-chain NFT marketplace has leaned heavily into its digital wallet offering since its release in November. Supporting fungible tokens, the product’s prioritization has coincided with Magic Eden’s push beyond digital collectibles as the market for NFTs moves further away from its frothy days in 2021 and 2022.

Users who want to claim TestME will need the NFT marketplace’s wallet, Magic Eden said in a blog post. U.K. and U.S. residents are excluded from participating in the rollout.

The window for claiming TestME will last two days, allowing users to “get comfortable with the process of claiming tokens,” Magic Eden said. Additionally, those two days will give Magic Eden the chance to vet any technical issues.

Citing the token’s lack of “intrinsic value,” Magic Eden said that it adopted the token purely for testing purposes and “discourages trading of the token.” 

Nevertheless, TestME will likely see some activity that mirrors moves similar to those of other projects.

MockJUP, a token released by the decentralized exchange aggregator Jupiter as a test for its launchpad in January, became a pseudo-meme coin for a short amount of time. It wasn’t ultimately supported long-term, but some early traders made money on the Solana token as degens aped in ahead of the anticipated, real-deal JUP airdrop.

Magic Eden said that TestME’s distribution will be limited to those who have engaged with the platform in the past six months. And even though users will need a Magic Eden Wallet to claim TestME, other types of wallets can be linked to it to provide proof that a user has recently engaged with Magic Eden’s services, the company said.

While Magic Eden entered the NFT market on Solana, the company has added support for several other chains, including Bitcoin and Ethereum. Still, the company views Solana as core to its business, with Solana token trading slated for the platform.

Originally, the Magic Eden Foundation’s governance token was set to be called NFTHowever, the foundation decided to keep Magic Eden’s branding attached to the asset as the platform expanded to support a version of Bitcoin-based fungible tokens called Runes.

More details about Magic Eden’s governance token, letting holders participate in voting on the platform’s direction, are set to be released following TestME’s rollout. Meanwhile, Magic Eden CEO Jack Lu has shared details about his vision for ME’s ultimate role.

“$ME will […] serve as an incentive layer to continuously help onboard, engage, and reward all Magic Eden users,” he wrote on Twitter (aka X) earlier this month, adding the token’s “integration will also reward the most long term continuous users.”

As the Magic Eden Foundation pushes forward with plans for a governance token, TestME may just be one step in a lengthy technical process. At the same time, the bare-bones tokens could generate some buzz—and eager wallet users—for what’s to come.

Bitcoin ETFs Are Booming as BlackRock Shatters Records – Decrypt

Bitcoin ETFs Are Booming as BlackRock Shatters Records – Decrypt



In case it wasn’t already obvious, Bitcoin exchange traded-funds (ETFs) are hot—with demand for the products smashing all expectations. 

Data from Bloomberg shows that of the 575 ETFs launched this year, 14 of the top 30 products have been either new Bitcoin or Ethereum funds, with the top four spots owned by Bitcoin funds.

And in the past four years, of the 1,800 ETFs that started trading during that span, BlackRock’s iShares Bitcoin Trust is the biggest by far in terms of inflows, the data shows. 

ETFs are popular investment vehicles that trade on stock exchanges. They allow investors to buy and sell shares that track the price of anything from the S&P 500 and gold to Bitcoin and real estate firms. 

In January, the Securities and Exchange Commission (SEC) approved the Bitcoin products, allowing 10 such funds to start trading on American stock exchanges after a decade of denials. 

The investment vehicles have been widely popular, attracting billions of dollars in months in flows. Last week, they collectively crossed the $20 billion mark—smashing expectations by taking just 10 months to do what gold ETFs did over five years.

The reason for the fast money, according to Bloomberg Intelligence ETF research analyst James Seyffart, is partly down to investors who had wanted to invest in Bitcoin for some time, but didn’t have a safe or easy way before the approval of the ETFs. Now that the ETFs are trading, that demand is rapidly entering the market. 

“I think it was partly pent-up demand,” he told Decrypt. “But it’s also new demand as people are learning more.”

He added that traditional financial institutions are interested in the products too—including hedge funds involved in futures trading. “That has helped improve flows and demand,” he said, adding that hedge funds have been going long on the ETFs and then selling the futures contracts.

Massive institutions—including Morgan Stanley and Goldman Sachs—now have exposure to Bitcoin via the new products. The price of Bitcoin even hit a new all-time high in March following their approvals. 

But the Ethereum counterparts haven’t had as much luck thus far. The SEC approved the ETFs for the second-biggest cryptocurrency—reluctantly, it appeared—in May. They haven’t done nearly as much in terms of inflows since trading began in July.

 

This is partially because Grayscale’s Grayscale Ethereum Trust (ETHE) previously operated like a closed-end fund rather than an ETF before July. Its subsequent conversion means that investors who previously had cash locked up in the fund have fast been redeeming shares—leading to massive outflows. 

So far, $3 billion has left the fund, bringing the total flows for all nine Ethereum ETFs currently trading to negative $472.7 million, Farside data shows.

However, that doesn’t mean demand won’t pick up. Investors have thrown cash at the other products, and that could mean a turnaround is on the horizon. 

“It’s just that the outflows from ETHE are overwhelming the inflows to these other [Ethereum] ETFs,” added Seyffart. “For now.”

US Government Crypto Wallet Drained of $20 Million in Suspicious Transfers – Decrypt

US Government Crypto Wallet Drained of  Million in Suspicious Transfers – Decrypt



Over $20 million worth of stablecoins and Ethereum was transferred from a wallet containing funds seized by the U.S. government Thursday, shifting assets tied to the 2016 hack of the crypto exchange Bitfinex to a five-day-old address. Some of those funds have now been moved to Binance, an off-shore exchange and the largest crypto trading platform in the world by volume.

Minutes before the transfers took place, the blockchain analytics firm Arkham Intelligence highlighted withdrawals from the lending protocol Aave in a tweet. It was the first time the funds had been touched in eight months, the company said.

According to Arkham’s platform, $1.25 million of the stablecoin Tether was withdrawn from Aave as well as $5.5 million of USDC. Those funds were subsequently sent to a wallet beginning “0x348” alongside $446,000 worth of Ethereum and $13.7 million of aUSDC, an interest-bearing token that represents USDC deposited in an Aave lending market.

The government-controlled wallet received millions of dollars of aUSDC two years ago. On the same day, it also received a hefty sum of the equivalent Aave-based token for Tether.

The pseudonymous blockchain sleuth ZachXBT said the activity appeared “nefarious” on Twitter. Most likely, the funds were flowing as a result of “theft,” the sleuth added.

Bitfinex was hacked in 2016 by a married couple from New York City, who later pleaded guilty to money laundering conspiracies. Taking advantage of a security breach at the exchange, Ilya Lichtenstein and Heather Morgan had $3.6 billion worth of digital assets seized by the authorities, according to a Department of Justice (DOJ) press release from August 2023.

Asked whether the transfers were conducted in relation to law-enforcement activities, the DOJ did not immediately respond to a request for comment from Decrypt.

The wallet that received millions of dollars of government-linked funds Thursday proceeded to use 1inch, an exchange aggregator, to swap stablecoins for Ethereum. It then began shuffling Ethereum in $40,000 chunks to a deposit address for the crypto exchange Binance, which ZachXBT flagged as suspicious behavior.

In total, $320,000 worth of Ethereum had been sent to Binance, as of this writing. At the same time, $80,000 worth of Ethereum had splintered off into other wallets.

When it comes to “0x348,” the wallet made its first transaction less than a week ago. And the wallet that funded it received its first funds two years before from the Australian cryptocurrency exchange CoinSpot, which does not operate in any other jurisdiction.

As of this writing, the government-controlled wallet was virtually empty. All of its assets were gone, aside from $127 worth of a Donald Trump-themed meme coin.

Checksum Verification for Web3j: Guarding Against Attacks


In today’s digital world, where automation and scripting are essential for developers, security remains a paramount concern. One of the simplest ways to install developer tools is through scripts downloaded directly from the internet. However, this convenience also comes with inherent risks, especially when dealing with external sources.

Web3j is a security-focused project. It has taken steps to reduce risks from running installer scripts. This includes protecting against remote code execution (RCE) threats.

The Problem: A Risk in Convenience

Web3j provides installation scripts to make setup easier for developers. Typically, users can run the following commands to install Web3j:

 

On macOS/Linux:

curl -L get.web3j.io | sh

 

On Windows:

Set-ExecutionPolicy Bypass -Scope Process -Force; iex ((New-Object System.Net.WebClient).DownloadString(‘https://raw.githubusercontent.com/hyperledger/web3j-installer/main/installer.ps1’))

 

While these commands make installation quick and effortless, they introduce a serious security vulnerability: if a malicious actor gains access to modify the script at the source, they can inject malicious code. Users who unknowingly run these compromised scripts may expose their machines to Remote Code Execution (RCE). This could allow attackers to take control.

The Solution: Built-in Checksum Verification

To address this vulnerability, we have introduced SHA256 checksum verification into the Web3j installation script itself. This means that users no longer need to manually verify the checksum—the script now checks its own integrity before executing. This built-in verification ensures that the script automatically checks whether it has been modified. This prevents the execution of any potentially malicious code.

Manual Checksum Verification for Extra Security

While the script performs its own verification, we also provide checksum values publicly so that users can independently verify them if they prefer to do so. This double layer of security is crucial for environments where strict verification processes are required.

The checksum values for the installation scripts are stored in the following files:

To verify the checksum manually, you can run the following commands for your respective operating system:

 

For macOS:

sed ‘/^CHECKSUM_URL=/d’ installer.sh | shasum -a 256 | awk ‘{print $1}’

For Linux:

sed ‘/^CHECKSUM_URL=/d’ installer.sh | sha256sum | awk ‘{print $1}’

For Windows:
Get-Content “installer.ps1” | ForEach-Object { $_ -replace “`r”, “” } | Where-Object { $_ -notmatch ‘^[\s]*\$ChecksumUrl’ } | Out-String

After running the command, compare the output hash with the respective checksum file from the Web3j GitHub repository. If they match, the script is safe to run. If not, avoid running the script and report the issue immediately.

Why Fixing This Issue is Important

Addressing the risk of RCE is critical because it directly impacts the security of the machines that run Web3j scripts. In a compromised scenario, an attacker can execute arbitrary commands on a victim’s machine. This could lead to data breaches, malware installation, or total system compromise.

By implementing checksum verification inside the script and offering a manual verification option, we greatly reduce the risk of executing malicious scripts. This ensures the Web3j community remains safe and secure.

Continuous Updates to Ensure Safety

Web3j remains committed to the security of its users. The checksum values for the installer scripts will be updated if there are any changes to the script in the future. Users are encouraged to always verify the checksum before running the script, especially after downloading a fresh copy.

Conclusion

In conclusion, while installer scripts provide a convenient way to get started with Web3j, they also come with potential risks. With the introduction of checksum verification inside the script and the ability for users to manually verify checksums, we have strengthened the security of the entire Web3j ecosystem. Users can now confidently execute the installation script knowing that it is authentic and free from tampering, protecting their systems from potential attacks.

Stay secure, and always verify!
