Memecoins are primarily built on blockchains that support smart contracts, with Ethereum and Solana being the most popular choices. Ethereum, as the pioneer of decentralised applications (dApps), hosts many early memecoins like Shiba Inu (SHIB) and PepeCoin (PEPE) due to its robust security and widespread adoption. However, high gas fees on Ethereum often push developers toward cheaper alternatives.

Solana has emerged as a favourite for newer memecoins (e.g., Bonk (BONK), Dogwifhat (WIF)) because of its low transaction costs and fast speeds, making it ideal for speculative trading. Other blockchains like Binance Smart Chain (BSC), Polygon, and Base (Coinbase’s chain) also host memecoins, balancing affordability with decent security.

Some memecoins, like Dogecoin (DOGE) and Shiba Inu’s original token, operate on their blockchains but lack smart contract functionality. Meanwhile, Avalanche, Arbitrum, and Fantom see occasional memecoin launches but with less dominance.

In summary:

Ethereum = High security, high fees (home of major memecoins).

Solana = Fast and cheap (trending for new memecoins).

BSC/Polygon/Base = Budget-friendly alternatives.

Standalone blockchains (DOGE) = Rare, limited utility.

The choice depends on cost, speed, and developer preference, with Solana currently leading the latest memecoin wave.
