World Chain Launches MiniKit 2.0 With 10x Faster Transaction Speeds

World Chain released MiniKit 2.0 on March 31, enabling developers to build applications once and deploy them across both web browsers and World App with as little as two lines of code. The upgrade slashes transaction confirmation times from 2 seconds to 200 milliseconds through Flashblocks integration.

The technical overhaul aligns World Chain development with Ethereum's EIP-1193 standard, a move that eliminates the friction developers faced when maintaining separate codebases for different deployment environments. Apps running inside World App now behave identically to standalone versions, cutting the overhead between building, testing, and distribution.

Flashblocks Delivers Sub-Second Finality

The custom Flashblocks implementation represents the headline performance improvement. For applications requiring fast feedback—trading interfaces, games, real-time interactions—the 10x reduction in confirmation latency removes a major UX bottleneck that plagued earlier World Chain deployments.

Gas fees also disappear from the user experience entirely. Through partnerships with Privy and ZeroDev's account abstraction infrastructure, apps can sponsor transaction costs. No wallet balances to maintain, no bridging required. The Charms application already pilots this feature in production.

Local Stablecoin Expansion

MiniKit 2.0 adds support for seven regional stablecoins: wARS (Argentina), wCOP (Colombia), wMXN (Mexico), wBRL (Brazil), wPEN (Peru), wCLP (Chile), and EURC. Developers can now build payment flows targeting specific markets without managing currency abstraction or region-specific infrastructure themselves.

World Build 3 Opens Applications

The timing coincides with World Build 3, the third cohort of the protocol's developer accelerator. Previous participants have raised over $15 million from VCs while shipping apps to millions of verified users, according to World.

The program kicks off with a four-day hackathon offering $20,000 in prizes. Top performers receive invitations to Build Week in Seoul alongside World's developer team, followed by three months of virtual programming and a Demo Day in San Francisco.

World maintains a presence at EthCC in Cannes from March 30 through April 2, where developers can explore MiniKit 2.0 at the Ruby Sponsors Gallery booth. For teams already building on World Chain, the upgrade path from existing Mini Apps should be straightforward given the shared interface between deployment environments.
