Since mid-2024, speculative trading in memecoins has sharply increased, bringing tokens such as “Fartcoin” to notable market capitalization. Even high-profile individuals like US President Donald Trump and First Lady Melania Trump have launched memecoins during this surge. This trend has intensified the risk of scams, including rug pulls and pump-and-dump schemes.
Memecoin scams often exploit decentralized exchanges (DEXs), which provide liquidity pools enabling token purchases. Scammers create these tokens, and when victims buy them, the liquidity enables scammers to dump their holdings and cash out, leaving investors with nearly worthless assets. Some scams falsely claim utility or partnerships with legitimate entities to attract investors.
Market manipulation in memecoins resembles pump-and-dump tactics, where prices are artificially inflated through coordinated trading or promotions before crashing when insiders sell. Unlike rug pulls—which end abruptly—pump-and-dump tokens may experience multiple rapid surges and crashes before abandonment. Bots are commonly used to accelerate these price manipulations.
A significant example is the $LIBRA memecoin scandal in Argentina. On February 14, 2025, Argentinian President Javier Milei tweeted support for $LIBRA, which claimed to fund small businesses in Argentina via the Solana Blockchain. The token’s market cap quickly surged to $4.5 billion before crashing hours later. Scammers drained nearly $100 million worth of Solana and USDC from the liquidity pool on the Meteora DEX, triggering a political crisis. Milei retracted his support, and a lawsuit was filed in New York naming Meteora and others as defendants.
Blockchain analytics tools can help identify memecoin scams by detecting smart contracts and wallet behaviors typical of these frauds. For example, automated behavioral detection models highlight connections between suspicious wallets and decentralized or virtual asset service providers (VASPs). This enables compliance teams to block transactions linked to scams and reduce consumer exposure.
