The crypto ecosystem is going through an expansion cycle where competition among blockchains is intensifying, especially in the decentralized exchanges (DEX) market. Indeed, long dominated by Ethereum, this sector is seeing the emergence of a significant competitor: Solana, whose trading volumes briefly surpassed those of Ethereum in February. This unexpected performance occurred despite an unprecedented crisis in the memecoin segment, these speculative cryptos that have long been a key economic driver of the network. Solana is holding on to its place among the DEX leaders, but the recent collapse of memecoins raises a major question: can the network maintain its position without this asset?
