Rug Pulls: A Guide to Recognizing DeFi Scams

Rug Pulls: A Guide to Recognizing DeFi Scams

Astute investors continually seek early-stage projects poised for success. Early involvement can lead to substantial gains – take the example of the Winkelvoss twins, who invested in Bitcoin (BTC) nearly ten years ago, now billionaires. However, impulsively jumping into projects without comprehensive research can lead to financial ruin, like the investors who lost $2.6 million in the Baller Ape Club NFT scam.

The crypto world is rife with high-risk, high-reward opportunities, marked by an influx of new projects generating excitement and investment. Yet, unlike traditional regulated markets, the crypto realm is nascent, with malicious players inventing novel ways to deceive investors.

A prevalent crypto scam is the "rug pull". Developers or creators hype up a new coin or NFT, then vanish with the invested funds. Tracing these fraudsters post-incident is challenging due to blockchain's decentralized, pseudonymous nature, which shields their identities.

What is a rug pull in cryptocurrency?

In the cryptocurrency world, a 'rug pull' occurs when project developers abruptly and intentionally abandon a startup after securing the trust and funds of their investors, leaving behind a worthless asset. This term is derived from the act of pulling the rug out from under someone. Rug pulls are prevalent in areas like decentralized finance (DeFi), NFTs, Web3, and various metaverse projects. In 2021, they accounted for 37% of all cryptocurrency scam revenue, amounting to over $2.8 billion.

The process often starts with creating a new cryptocurrency token, which is then listed on a decentralized exchange and paired with a major coin like Ethereum. The fraudsters leverage social media's marketing power to launch a compelling promotional campaign, attracting investors with promises of extraordinary returns, akin to a Ponzi scheme. As the token's value increases, the development team eventually dumps their share, escaping with investor funds.

Rug pulls are particularly rampant in DeFi due to the ease of creating new tokens and listing them on decentralized exchanges without code audits, which are essential for checking smart contract vulnerabilities. This type of scam adds to the distrust in a market already known for its volatility, marking the crypto and DeFi ecosystems as a digital Wild West

Types of Rug Pulls

Rug pulls in the cryptocurrency sphere manifest in two primary forms: hard and soft. A hard rug pull is abrupt and unexpected, causing token values to plummet to zero instantaneously, signaling to investors that they have been defrauded and that the creators have abandoned the project. On the other hand, a soft rug pull unfolds over a longer period, where developers maintain a facade of commitment to the project while surreptitiously selling off their coin shares.

These fraudulent practices fall into three categories: liquidity theft, limiting sell orders, and dumping.

  • Liquidity Theft:

The most frequent form of exit scam, liquidity theft, occurs when token creators withdraw all the funds pooled into a project. DeFi trading platforms depend on a collection of crypto tokens to enable trading, exchanges, or loans, typically secured by smart contracts. However, if the developers who designed these contracts had ulterior motives, they could exploit this system to gain access to and extract the locked funds. This results in the project's native token losing all value.

  • Limiting Sell Orders:

In this subtler approach, scammers restrict or entirely block the ability to sell coins on a platform. When an exchange garners significant traffic, the fraudsters behind it might alter the project's code to permit only purchases, not sales, of the native token. This tactic, which often involves manipulating smart contract technology, funnels money directly to the corrupt developers, leaving legitimate users unable to sell their holdings.

  • Dumping:

Also known as "pump-and-dump", this method relies on generating false excitement, typically through social media, about a new token associated with a seemingly promising project. Investors are drawn in, inflating the token's value. At the peak, developers sell off their shares and exit, causing the token’s value to crash, to the detriment of the remaining investors.

All these tactics, whether through immediate extraction, manipulating selling rights, or orchestrated market manipulation, share the ultimate goal of illicitly maximizing gains at the expense of unsuspecting investors.

The Biggest Rugs Ever

Understanding crypto rug pulls and their major forms is crucial, especially in light of some of the largest and most notorious rug pulls in the crypto world:

  • OneCoin: A notorious cryptocurrency-based Ponzi scheme led by Ruja Ignatova, who disappeared in 2017 after raising $4 billion. OneCoin operated more like a multi-level marketing scheme, selling educational materials rather than a functional cryptocurrency. The founder vanished in 2017, leaving her brother in charge, who was later arrested in 2019 for fraud and money laundering.
  • Thodex: In 2021, Turkey launched an investigation into Thodex and its founder, Fatih Faruk Ozer, for fraud and establishing a criminal organization. Thodex suspended operations under the pretext of a partnership offer, never to resume, with trading volumes reportedly in the billions.
  • Anubis Dao: Despite lacking a website, this project raised $60 million in ETH through a token sale. Hours into the sale, the funds were transferred to another address and never recovered, showcasing the risks of investing in projects without robust digital footprints.
  • Defi100 Coin: Known for its blatant scam, the Defi100 project displayed a message on its website openly admitting to the scam and taunting investors. The creators allegedly made off with around $32 million in investor funds.
  • Stable Magnet: This scam, valued at over $27 million, exploited vulnerabilities in Etherscan and BscScam verification systems, allowing the scammers to use a different code library than the one mentioned in the source code.
  • Luna Yield: Promising optimized yield farming, Luna Yield disappeared with approximately $6.7 million, transferring funds through Tornado cash to evade tracing and shutting down all digital presence.
  • Swipathefox Project: Initiated by NBA star De’Aaron Fox, this NFT project generated significant excitement but was abruptly abandoned, leaving investors with a loss of $1.5 million. The project's sudden closure highlights the risks of celebrity-endorsed crypto ventures.
  • Iron Finance: This case involved a mass sell-off by whales in the Iron Finance liquidity pools, drastically impacting the value of TITAN and leading to its collapse. The platform continues to operate, but TITAN is no longer used, showing how market dynamics and investor behavior can rapidly affect a token's stability.

Each of these instances underscores the diverse methods and scales of crypto rug pulls, from Ponzi schemes to blatant admissions of fraud, revealing the volatile and sometimes treacherous nature of the cryptocurrency investment landscape.

How to avoid rug pulls

To safeguard against falling victim to a rug pull in the cryptocurrency world, there are several best practices that, when combined with other protective measures, can significantly reduce the risk:

  • In-depth Research: Before investing, thoroughly research the project. Look for signs of transparency, such as the visibility of the development team, their past project history, and their standing within the crypto community.
  • Beware of Anonymous Teams: Projects led by completely anonymous teams are riskier. While anonymity doesn't automatically imply fraud, it does lack accountability, which can be a warning sign.
  • Audit Reports: Check if the project has undergone an audit by a reputable third party. Carefully review the audit report for any highlighted vulnerabilities.
  • Community Engagement: Actively engage with the project’s community on platforms like Telegram and Discord. Ask questions and gauge the responses of the community. A community that’s secretive or hostile to inquiries could be indicative of underlying issues.
  • Moderate Your Investment: If you're intrigued by a project but still uncertain, consider starting with a smaller investment to minimize potential losses.
  • Liquidity Analysis: For DeFi projects, verify the liquidity levels and the duration for which funds are locked. This can prevent abrupt and large-scale withdrawals. Examine the project's white paper and smart contract for details and potential loopholes that could allow developers to unexpectedly withdraw funds.
  • Stay Informed: The landscape of cryptocurrency scams is ever-evolving. Keeping up-to-date with the latest scamming tactics can aid in early threat detection.
  • Healthy Skepticism: Approach overly optimistic promises with caution. Offers that seem too good to be true, especially those promising high returns, are often deceptive.

Incorporating these strategies into your due diligence process can provide a more robust defense against the increasingly sophisticated and varied methods used in crypto rug pulls. It's important to remember that while no single measure is foolproof, a combination of these practices significantly enhances your ability to discern legitimate projects from fraudulent ones.
