With few DeFi protocols and tokens deployed on Base on the time, many of those early entrants positioned bets on BALD, a so-called memecoin riffing on Coinbase CEO Mind Armstrong’s hairstyle — or lack of 1.
Spurred on by the nameless BALD token creator depositing thousands and thousands of {dollars} of liquidity into its buying and selling pool — an indication many took as proof BALD’s creator was reliable — the token rose a dizzying 3,000% hours after its launch.
However the occasion was short-lived.

Evaluation of onchain knowledge reveals that by pulling liquidity, the BALD creator gained roughly $6 million.
Magnate Finance $6.4 million in August
Suspected rug pulls are the commonest assault vector in crypto resulting from one main motive — the serial nature of these ostensibly accountable.
Take the Magnate Finance incident. The protocol launched on Base in August and was briefly the blockchain’s massive kahuna with $6.4 million in deposits.
Onchain records confirmed that the protocol was linked to the identical wallets as these tied to a previous rug pull at Solfire Finance. The information have been first highlighted by safety researchers together with ZachXBT, the pseudonymous blockchain sleuth.
Magnate Finance’s builders used their management over the protocol to “manipulate” the price oracles it relied on to appropriately worth the crypto property deposited to the protocol, in response to an evaluation from blockchain auditing agency QuillAudits.

Xirtam $3.4 million and Swaprum $3 million in Could

Typically, the regulation catches up.
That was the case for UAE-based French nationwide Aurelien Michel, the person accused of abandoning the Mutant Ape Planet NFT assortment he created in a self-confessed rug pull.
Aurelien, arrested in January for his half within the $2.9 million rug pull, pled guilty in November and will withstand 5 years in jail, plus a $1.4 million fantastic.
