Maple Finance 2.0 overhaul aimed at speeding up the defaulting process
Maple Finance is a decentralized credit market powered by blockchain technology. Instead of requiring overcollaterlization of loans, it instead allows managers, called “Pool Delegates” to issue loans from its lending pools based on a set of risk-management criteria, according to the protocol’s documents. Introducing Maple 2.0. Maple 2.0 is a fundamental overhaul of the smart contract architecture. The new contracts are modular and robust and will facilitate Maple bringing capital markets on-chain. pic.twitter.com/5GGsMXaXhv — Maple (@maplefinance) December 14, 2022 However, in the wake of FTX’s collap, the platform experienced two major defaults from borrowers on the platform. On Dec. 1, algo trading and market maker Auros Global missed its payment of 2,400 Wrapped Ether (wETH) follo...
ApeCoin geo-blocks US stakers, two Apes sell for $1M each, marketplace launched
United States-based ApeCoin (APE) holders could miss out on staking rewards after the U.S. was added to a list of regions geo-blocked from using an upcoming APE staking service. Blockchain infrastructure company Horizen Labs, which is building the site on behalf of the ApeCoin decentralized autonomous organization (DAO), revealed the news in a Nov. 24 update regarding ApeStake.io on Twitter, saying “unfortunately, in today’s regulatory environment, we had no good alternative.” Ape Staking Update: Big thanks to the talented community devs for their helpful improvements. Bug Bounty AIP delayed us a bit, so we shortened the pre-deposit period by a week to keep our original 12/12 go-live. Alternate front-end sites going live. See card. pic.twitter.com/mgmP7X3SwQ — Horizen Labs (@HorizenLabs) N...
White hat finds huge vulnerability in ETH to Arbitrum bridge: Wen max bounty?
A self-described white hat hacker has uncovered a “multi-million dollar vulnerability” in the bridge linking Ethereum and Arbitrum Nitro and received a 400 Ether (ETH) bounty for their find. Known as riptide on Twitter, the hacker described the exploit as the use of an initializing function to set their own bridge address, which would hijack all incoming ETH deposits from those trying to bridge funds from Ethereum to Arbitrum Nitro. Riptide explained the exploit in a Medium post on Sept. 20: “We could either selectively target large ETH deposits to remain undetected for a longer period of time, siphon up every single deposit that comes through the bridge, or wait and just front-run the next massive ETH deposit.” The hack could have potentially netted tens or even hundreds of millions worth...
Cardano gets listed on Robinhood but ADA bulls are running out of steam, risking 40% drop
ThCardano (ADA) market has witnessed back-to-back pieces of good news since Aug. 31, from its listing on Robinhood, a U.S.-based retail investment platform, to the release of its first lending and borrowing protocol, Aada Finance. Additionally, Cardano developer IOHK stated that they are close to clinching “three critical mass indicators” that would lead to the launch of their long-awaited Vasil hard fork in September. Vasil aims to improve Cardano’s scalability and transaction throughput through pipelining. The upgrade could also improve the decentralized application (DApp) and smart contract capabilities by changing the Plutus script, a programming language used for smart contracts on the Cardano blockchain. This week, we’re well on our way to hitting our...
Solana and Ethereum smart contract audits, explained
As you might expect, this depends on how complex a smart contract is. According to Hacken, this can extend to $500,000 for larger projects where there are more lines of code — not least because of the additional engineering hours it’ll take. The company argues these costs pale into comparison with the economic damage that a smart contract vulnerability can bring. Hacken cites data showing that, in 2021, 80% of the incidents affecting decentralized applications related to smart contracts — with losses hitting $6.9 billion. Breaking this down even further, and we can see that the average cost per project stands at $47 million. Somehow, $500,000 looks a lot less expensive now. Overall, 60% of its clients have been based on Ethereum so far in 2022. And here&...
Solana price just one breakdown away from a 40% slide in June — here’s why
Solana (SOL) is nearing a decisive breakdown moment as it inches towards the apex of its prevailing “descending triangle” pattern. SOL’s 40% price decline setup Notably, SOL’s price has been consolidating inside a range defined by a falling trendline resistance and horizontal trendline support, which appears like a descending triangle—a trend continuation pattern. Therefore, since SOL has been trending lower, down about 85% from its November 2021 peak of $267, its likelihood of breaking below the triangle range is higher. As a rule of technical analysis, a breakdown move followed by the formation of a descending triangle could last until the price has fallen by as much as the triangle’s maximum height. This puts SOL’s bearish price target at $22.50 ...
Maiar decentralized crypto exchange goes offline after bug discovery
Minutes before 12 a.m. UTC on June 6, the CEO and co-founder of the Elrond Network, Beniamin Mincu, tweeted that he and his team were “investigating a set of suspicious activities” on the Maiar decentralized crypto exchange (DEX). Soon after the exchange was taken offline with Mincu reporting the issue was identified and an “emergency fix” was being implemented. In a Twitter thread posted almost 24 hours later around 11 p.m. UTC on June 6, Mincu said a potentially critical bug was identified which opened “an exploit area that we simply had to address and mitigate immediately.” The suspicious activities have been possibly identified and explained in a Twitter thread by pseudonymous on-chain analyst “Foudres” who revealed the potential attacker deployed a smart contract that someho...
