How World Delivers Global-Scale Onchain Performance

When you’re building infrastructure for a global onchain network designed to serve all of humanity, performance is paramount. For World Chain, the L2 purpose-built for human-centric apps, every millisecond of latency, every nine of uptime, and every scalability unlock matters for real users interacting with the World App across the globe.

World is already the largest onchain app in the world with over 30.5 million users, 501 million wallet transactions, and 14.1 million unique humans verified. They're bringing financial access to the unbanked, underbanked, and anyone seeking a better onchain experience. Behind the scenes is infrastructure and tools that can deliver on that promise.

Scaling With Purpose

From the beginning, the World team knew they needed infrastructure that could match the scale of their mission: building the world’s most inclusive financial network. As adoption accelerated across the globe, so did the technical demands.

They needed a partner who could deliver at global scale with:

• A fully customizable rollup solution

• Mission-critical wallet infrastructure

• Fast and reliable RPC API and data APIs

“When we were searching for infrastructure vendors, what mattered most was enterprise scale and support. Alchemy was hands down the clear leader across every product we needed—the only logical choice.”

— Steven, Head of Protocol and Research at Tools For Humanity

Today, World’s onchain ecosystem is powered by our full platform—from RPC APIs to Smart Wallets to Rollups. And beyond core infra, Alchemy has partnered closely with World on several custom innovations:

• Priority Blockspace for Humans (PBH): World Chain is designed to prioritize transactions from verified humans over bots. Alchemy helped evaluate PBH performance and ensured readiness for mainnet launch.

• Flashblocks: A major UX upgrade, Flashblocks introduces 200ms “preconfirmation” updates—making transactions feel instant. Our teams are working hand-in-hand to validate, battle-test, and productionize Flashblocks, so 30M+ users benefit from day one.

Pushing Performance Boundaries, Powered by Cortex

Cortex is the engine that now powers the full Alchemy stack—every RPC call, every transaction broadcast, every wallet interaction. Built for sub-50ms latency, elastic scalability, and 99.99% reliability, Cortex is what makes today’s breakthroughs possible.

Spending 1000+ hours over days and nights brainstorming, designing, implementing, and launching solutions with World engineers, we’ve already unlocked major wins:

• 44% Faster Time to Mine: Sequencer tuning reduced confirmation times from 5.5s to 3.1s—meaning faster feedback for users across the globe.

• 74% Drop in Gas Estimation Latency: Bundler improvements cut alchemy_requestGasAndPaymasterAndData latency from ~380ms to ~100ms.

• Global Resilience: Cortex now supports 1M+ requests per second with near-perfect reliability across APAC, EU, and North America.

“Working with Alchemy has consistently been a great experience. Their team has deep expertise in running critical infra at scale. They free us up to focus on high-impact workstreams—and push us to raise the bar for how we operate.”

— Daniel, Senior Software Engineer at Tools For Humanity

Results That Matter

Together, we were able to deliver on both of our missions - to provide the world with better experiences onchain.

• 1.9M daily wallet transactions, seamlessly handled

• Access across 150+ countries with sub-second RPC response times

• 30.1M+ World App users enjoying fast, intuitive onchain experiences

And we’re just getting started.

A Shared Mission

World isn’t just building for crypto natives—they’re building for everyone. And when you’re building for billions, infrastructure can’t be an afterthought. It has to be world-class from day one.
