According to data shared by blockchain security company Blockaid, 50% of pre-sale tokens launched in the Solana ecosystem between November last year and February this year were malicious, according to PANews. Blockaid co-founder Ido Ben-Natan pointed out that the popularity of legitimate meme coins and scammers taking advantage of user FOMO emotions are two factors that have driven the spread of scams in the Solana ecosystem. In addition, Solana's performance in processing transactions has been affected by the popularity of Meme coins and the large amount of spam sent to the blockchain network by programmatic trading robots. These findings highlight the need for the Solana ecosystem to strengthen security measures.
