    For the past three weekly candles, Bitcoin has failed to make a move below $45,500 while posting higher highs, suggesting traders should look to bid around $45,000-$46,000 and use the middle band as an initial target, currently at $52,972.

    ‘Critical’ Polygon Bug Put $24 Billion in Tokens at Risk Until Recent Hard Fork

    Ethereum scaling project Polygon was at risk of losing all of its MATIC tokens until it upgraded its network in early December. Details about the bug were shared on December 29th, where attackers would have been able to arbitrarily mint all of Polygon’s MATIC tokens from its MRC20 contract.

    The vulnerability was first discovered by white hat hacker Leon Spacewalker and was reported on bug bounty platform Immunefi.

    A security partner discovered a vulnerability ✅Fix was immediately introduced ✅Validators upgraded the network ✅No material harm to the protocol/end-users ✅White hats were paid a bounty— Polygon | $MATIC (@0xPolygon) December 29, 2021

    The vulnerability put more than 9.27 billion MATIC at risk that is valued at around $23.6 billion at the time of writing, with the figure representing the vast majority of the token’s total supply of 10 billion.

    Polygon noted that the bug was resolved at Block #22156660 via an “Emergency Bor Upgrade” to the Mainnet on Dec. 5 at around 7:27 am UTC. The network noted that a “malicious hacker” managed to steal 801,601 MATIC ($2.04 million) before the bug was resolved. The blog post said:

    The Polygon core team engaged with the group and Immunefi’s expert team and immediately introduced a fix.

    Robinhood Crypto Wallet to Launch in January, Shiba Inu Could Be Listed Soon

    After months of trial, American financial services company Robinhood announced that a beta version of its cryptocurrency wallet will be launched in January.

    Go Ethereum (Geth) team in November 2020. Under the guidelines, projects or developers report on key bug fixes 4-8 weeks after they go live to avoid the risk of being exploited at the time of patching.

    According to Immunefi, Whitehat hacker “Leon Spacewalker” was the first to report on the security hole on Dec. 3 and will be rewarded with $2.2 million worth of stablecoins for their efforts, while the second unnamed hacker, referred to as “Whitehat2” will receive 500,000 MATIC ($1.27 million) from Polygon.

    Polygon’s co-founder Jaynti Kanani emphasized the network’s ability to promptly resolve the critical bug, noting in the blog post that:

    What’s important is that this was a test of our network’s resilience as well as our ability to act decisively under pressure.

    Taking the deflationary route after its London Hardfork four months ago, Ethereum began burning Ether tokens.

    Since then, Ethereum has burnt 1,283,226 ether worth close to $4.8 billion (using today’s price of $3,700). OpenSea is the biggest burner of ETH with 134,126 ether across 9.5 million transactions. On the Ethereum mainnet, 122,365 ether has been burnt since August 5.

    Regardless of Ethereum outperforming Bitcoin in 2021, Justin Sun, the founder of TRON, has continued dumping his ETH holding.
    According to analytics firm Wu Blockchain, since the start of December, Sun has sold 165,989 ETH – approximately $592 million.

    According to a post shared by Colin Wu, the founder of Tron did not sell his Ethereum holding for personal profit.

    , the trading volume of non-fungible tokens (NFTs) surpassed $13 billion in 2021 compared to just $33 million in 2020. OpenSea facilitated nearly 88% of the total trade volumes for 2021 and Solana NFT marketplace Magic Eden saw growth during Q4 2021, becoming the second largest venue in December.

    Aave’s Newest Market: Real World Assets

    On December 28th, Ethereum-based lending protocol Aave added 7 new markets using real world assets in partnership with Centrifuge.

    The lower Bollinger band at $2,979 should provide strong support if the downward trend continues. A weekly close above $3,887 would point to a bullish outlook.

    The daily chart for ETH below shows that $3,910 is a key level for bulls to overcome. If there’s a daily close above the middle band, then it should provide a bullish outlook for ETH.

    The lower band currently lies at $3,615, which could provide a good buying opportunity.

    LINK is the only cryptocurrency available for leveraged trading on Rollbit that has seen an increase in price over the past 7 days, benefitting from a boost to eh valuations of DeFi-related assets.

    The bug was found in the transfer function of its MRC20 contract used for gasless transactions on the network.

    After the bug was reported, Polygon patched the bug by leveraging a stealth hard fork working alongside all of its validators and node operators. Even though the vulnerability was fixed within a few days, it could not stop an unknown black hat hacker from stealing 801,601 MATIC tokens worth $1.6 million at the time. In a post-mortem, the team reported:

    “Despite our best efforts, a malicious hacker was able to use the exploit to steal 801,601 MATIC before the network upgrade took effect.”

    The situation could have been far worse had this been delayed further.
