Rug Pull
A rug pull is a malicious maneuver where crypto developers abandon a project and run away with investors' funds. This typically happens in decentralized finance (DeFi) projects, where developers create a token, list it on a decentralized exchange, and lure in investors. Once the liquidity pool reaches a sufficient size, the developers withdraw all the paired liquidity (the 'rug'), causing the token's value to crash to zero and leaving investors with worthless assets.
Explain Like I'm 12
A rug pull is like a dishonest carnival owner who invites you to play a game, promises a huge prize, and once you pay to play, they pack up the entire stall and leave overnight. In crypto, developers set up a trap, wait for people to put money in, and then steal all the liquidity out of the system.
Why It Matters
Rug pulls are the most common form of exit scam in the crypto space. They represent a massive risk for retail investors participating in high-yield, unverified liquidity pools.
How It Works
Developers create a token with no real utility or roadmap. They pair it with a major asset like ETH or USDT in a liquidity pool. As organic buying increases the price, the developer, who holds the majority of tokens, sells their entire supply, then removes the underlying liquidity from the pool, making it impossible for anyone else to sell.
Real-World Example
The AnubisDAO rug pull saw developers drain $60 million worth of ETH from a liquidity pool just hours after the project's launch.
Advantages
- Teaches extreme caution with new tokens
- Encourages community vetting of protocols
- Highlights the need for audited liquidity locks
Limitations
- Almost impossible to recover lost funds
- Targets the most vulnerable retail participants
- Difficult to prosecute due to anonymity
Common Misconceptions
- Many users believe that high returns (APY) are a sign of a good project, not realizing they are often a bait for a rug pull.
- People think that once a token is on a DEX, it is 'legitimate' or 'safe,' ignoring that anyone can create a liquidity pool.

Liquidity Pool
A liquidity pool is a crowdsourced collection of digital assets locked in a smart contract to facilitate decentralized trading and lending. Unlike traditional order books where buyers and sellers must be matched, liquidity pools use Automated Market Makers (AMMs) to enable permissionless exchange. By pooling funds, the protocol ensures that there is always a counterparty available for trades, maintaining market depth even for less popular tokens and reducing reliance on centralized intermediaries.
51% Attack
An attack where one entity or coalition controls enough consensus power to reorganize blocks, censor transactions, or attempt double spending.
Address Poisoning
A scam where attackers create lookalike address activity so victims may accidentally send funds to the wrong address.
Audit
A smart contract audit is a comprehensive, systematic examination of a blockchain project's source code by independent security experts. The goal is to identify vulnerabilities, logical errors, and potential security flaws that could lead to exploits or financial loss. Auditors review the code for compliance with best practices, test for edge cases, and analyze the interaction between different smart contracts to ensure the protocol functions as intended before it is deployed on a mainnet.
Bridge Exploit
An attack that compromises a cross-chain bridge's contracts, validators, keys, proofs, or custody mechanisms.
Bug Bounty
A program that rewards researchers for responsibly reporting valid security vulnerabilities.
