Bug in Solana Token Lending Contract Fixed, More Than $2 Billion Made Exploitable

solana

A bug in the token lending contract of the Solana Program Library (SPL) was recently found and fixed by Neodyme, a security auditing firm. The bug, that was discovered a couple of months back, could have affected several decentralized finance protocols holding more than $2 billion in total value locked (TVL). Their team identified the possible protocols using this contract (or derivatives of it) and disclosed the bug immediately.

Solana SPL Rounding Bug Puts Funds at Risk

A bug in one of the token lending contracts that is part of Solana’s Program Library (SPL), a group of on-chain programs targeting the Sealevel parallel runtime on Solana, put the funds of several protocols at risk. Neodyme, a security agency, had disclosed this vulnerability months ago and alerted about it, but the bug, due to its apparently innocuous effect, had not been resolved.

The bug caused a rounding error that delivers more tokens than the ones being deposited by the users to the contract. However, the bug was not exploitable without an organized attack that targeted the vulnerability directly. Neodyme, the auditing group, managed to reproduce it and create a script that took advantage of it.

Importance of Open Source

More than $2 billion in several tokens on these protocols were at risk of being drained slowly by taking advantage of this exploit. More so, if the attack had been conducted in a smart way, it wouldn’t have triggered any alarms, and would just be detected as a slow drain of APY in some pools. Neodyme remarked about the importance of open source code for auditors to be involved and help correct these kinds of bugs. It stated:

We believe the most secure code is open-source, and as auditors we believe one of the best ways to write better code is to understand vulnerabilities.

After discovering this exploit, Neodyme shared its existence with teams that would probably be using the program as a tool for their operations. Among these were some protocols that are not open source on the Solana chain, and cannot be directly verified by their users. This made it difficult for them to directly verify whether these platforms were exploitable by the bug. However, they communicated with the teams behind these protocols, who are in charge of fixing the issue individually.

The SPL token-lending contract had already been reviewed before, and two projects using it have also been audited independently: Solend by Kudelski and Larix by Slowmist.

Alchemy and Infura block access to Tornado Cash as Vitalik Buterin weighs in on debate

According to Twitter user @0xdev0, on Monday, Web3 development platform Alchemy and Infura.io blocked remote procedure call (RPC) requests to cryptocurrency mixer Tornado Cash, preventing users from accessing the applications. The day prior, the U.S. Treasury placed 44 smart contract addresses linked to Tornado Cash in the Specially Designated Nationals and Blocked Persons (SDN) list. U.S. persons and entities are prohibited from blockchain or business interactions with Tornado Cash under t sanctions, with the possibility of criminal liabilities for violations.

The move came after the U.S. Treasury alleged individuals and groups had used the privacy protocol to launder more than $7 billion worth of crypto since 2019, including the $455 million stolen by the North Korea-affiliated Lazarus Group. Almost immediately after the announcement, stablecoin issuer Circle froze USD Coin funds held within Tornado Cash’s smart contracts. Meanwhile, programming repository GitHub took down the project’s main page and blocked developer access.

Vitalik Buterin, the co-founder of Ethereum, claimed that he used Tornado Cash to donate to Ukraine. The intent, as told by Buterin, was to protect the financial privacy of the recipients so that their enemy, the Russian government, would not have full details of the transaction.

I’ll out myself as someone who has used TC to donate to this exact cause.

Others have also pointed out the mixer’s privacy applications, such as for an individual getting paid in crypto who doesn’t want an employer to see their financial details, or paying for a service in crypto who doesn’t want the service provider to see the past transactions from their wallet. On the other hand, the tool has, in part, acted as a hotspot for enabling anonymous hackers to launder stolen funds from protocol exploits particularly cross-chain bridges. More than $2 billion worth of funds has been stolen from such applications year to date.

Reddit partners with FTX to enable ETH gas fees for community points

After moving away from Bitcoin (BTC) payments years ago, online forum Reddit now seems to be inching closer to embracing cryptocurrency payments via a new partnership with the FTX exchange.

Sam Bankman-Fried’s crypto exchange FTX and Reddit announced in a joint statement on Tuesday that the platform intends to integrate Reddit’s Community Points in the United States, the European Union, Australia and other markets.

The partnership features the integration of FTX Pay as a payment and crypto exchange solution to unlock new crypto-enabled perks for Reddit Community Points. Introduced in May 2020, Reddit Community Points are a measure of reputation in communities or subreddits, allowing users to own a piece of their favorite communities.

“As a unit of ownership, points capture some of the value of their community. They can be spent on premium features and are used as a measure of reputation in the community,” Reddit said when launching the Community Points two years ago. Reddit Community Points are based on Arbitrum, one of the most Ethereum scaling solutions.

With the new integration, users will be able to purchase Ether (ETH) from supported Reddit apps via FTX’s payment and exchange infrastructure platform FTX Pay. The cryptocurrency can be used to pay blockchain gas fees, or network fees for their Community Points transactions on-chain.

“We’re always working to empower communities and introduce new ways to use Reddit, and decentralized, self-sustaining blockchain technology allows us to do that. By working with FTX, we’re able to do this at scale,” Reddit staff software engineer Niraj Sheth said.

Bankman-Fried noted that the partnership with Reddit marks FTX s commitment to empower online communities to harness the power of blockchain. “FTX Pay’s payment and exchange infrastructure integrates with Reddit Community Points, making the customer experience a more seamless process,” he added.

The news comes amid Arbitrum developer Offchain Labs launching the Arbitrum Nova chain on Tuesday. Arbitrum Nova, the second chain launched in the Arbitrum ecosystem, is designed to serve as the premier solution for Web3 gaming and social applications. Apart from Reddit and FTX, other firms like Google Cloud, Consensys, P2P and QuickNode participated in the launch by becoming inaugural members of Nova’s “Data Availability Committee.”

One of the most popular websites in the United States, Reddit has been largely involved in the crypto and blockchain industry for many years. The discussion platform is known for once allowing users to pay for their premium membership in Bitcoin but removing the opportunity in 2018.

Reddit co-founder Alexis Ohanian has been widely involved in crypto, launching a $100 million Web3 investment fund last year. Ohanian subsequently launched another $200 million Web3 and social media fund in collaboration with the Ethereum scaling solution Polygon.

Institutions flocking to Ethereum for 7 straight weeks as Merge nears: Report, “Greater clarity” around the Merge has driven institutional inflows into Ethereum products, according to a CoinShares report. Is the ETH merge finally around the corner and will it bring new all time highs to ETH or has the price already been factored into the current price?

Circle freezes blacklisted Tornado Cash smart contract addresses, Crypto data aggregator Dune Analytics said that, on Monday, Circle, the issuer of the USD Coin (USDC) stablecoin, froze over 75,000 USDC worth of funds linked to the 44 Tornado Cash addresses sanctioned by the U.S. Office of Foreign Assets Control’s Specially Designated Nationals and Blocked Persons (SDN) list. Could this mark the end for Tornado Cash or is there a way they can redeem themselves?

Next up is a new segment called “Quick Crypto Tips,” which aims to give newcomers to the crypto industry quick and easy tips to get the most out of their experience. This week’s tip: Have some funds ready to buy further downturns.
