Infra breakthroughs are about to make onchain games feel instant.

One name leading the charge? @megaeth_labs — a new Ethereum Layer 2 targeting 100K TPS and 10ms block times. Its testnet is live now, and early results show that these numbers aren’t just marketing.

Here’s what MegaETH is building, and why it might be the fastest chain yet.👇

~~ Overview by @wmpeaster ~~

This kind of speed will be a breakthrough for builders and users. For reference:

Mainstream competitive online games are best at 30–60 ms latency. MegaETH is on track to beat that — and through open, onchain infrastructure rather than closed servers. This makes it valuable for more than games: think DeFi, social, and more.

Fast chains are multiplying, but MegaETH is set to join Solana at the top. Solana’s “shreds” enable ~15 ms block times, with community tools like MagicBlock getting ~10 ms. The fastest Ethereum Layer 2s are still around 200 ms at best.

This makes MegaETH’s arrival important — it enables entirely new Ethereum-native culture apps that weren’t previously viable.

That said, speed alone isn’t enough. A successful chain needs more than just one strong technical feature.

The core point: MegaETH could mark a paradigm shift and become a hub for high-performance apps. It’s worth tracking the network and familiarizing yourself with its early ecosystem.

You can add MegaETH’s testnet to your wallet via Chainlist and get testnet gas at testnet (dot) megaeth (dot) com.

To explore, start with Fluffle Tools by Loudio creator @0x_ultra. It offers app guides, builder tools, and more. Toggle “Live on Testnet” to find usable apps.

Then if you're interested in diving in, some projects on the culture side of things that I think are worth exploring or tracking early on include:

🧱 @thirdweb — An onchain dev platform that supports MegaETH's testnet and other EVM-compatible chains. It lets you easily deploy pre-built smart contracts, like NFT collections or open-edition drops, so if you're interested in being a creator on MegaETH this is a great place to start.

🎉 RaribleFUN — By the @rarible team, this is an experimental NFT marketplace designed for high-speed trading on the MegaETH testnet. If you're more of a collector than a creator, this is one avenue to start nabbing your first NFTs on the chain.

🪙 @XLmemeCom — A multichain memecoin launchpad, imagine a more streamlined and aesthetically pleasing pump (dot) fun and with deployments on multiple networks, including MegaETH's testnet. If you want to make your own memes or degen into new coins, consider exploring this platform.

🃏 @Showdown_TCG — A free-to-play, 1 vs. 1 poker adaption, this deck-building game uses special "action cards" to bring more strategy and unpredictability to players' hands. The title recently launched its closed alpha, with its closed beta slated for later this year, so keep your eyes peeled here if you're a fan of card games.

🔮 @playguessbest — A prediction market platform that operates through a Telegram bot through which you can make private betting rooms for your friends or community. You'll need a Telegram account to get started then, and funding is currently via Solana, but the underlying game actions are facilitated by the MegaETH testnet.

📌 HashPin — A protocol by @monsieurbarq for "proving the existence and ownership of anything." It lets you register any digital file by hashing it and tying it to your wallet address, with an additional option to claim your pinned hashes as NFTs to your wallet.

Ultimately, these projects are just a taste of what's to come on MegaETH, but they are initial opportunities to start getting better acquainted with the network and the kind of real-time UX it can offer. Dive in today to get ready for tomorrow!
