What is World App?

World App is the first wallet created for the Worldcoin project. It gives people access to private, decentralized digital identity through World ID and decentralized finance through cryptocurrencies and digital stablecoins like digital dollars. World App is the first tool allowing people to interact with their World ID, but the protocol is permissionless so other teams may also develop other tools to integrate with this critical identity layer. 

World App was developed and is operated by Tools for Humanity, the same technology company that developed the Orb—a biometric imaging device that verifies World IDs for people. 

What can I do with World App?

World App is the first app that supports World ID—a global identity protocol that enables people to digitally prove their uniqueness and humanness in a privacy-preserving way. With World App, anyone can sign up for a verified World ID at an Orb and then use it to seamlessly sign in to websites, apps and crypto dapps without sharing personal data like names or email addresses.

The World App wallet also gives people access to decentralized finance. Individuals can use it to save, send, deposit and withdraw digital money and explore and use crypto. This is made possible through partnerships with reputable services providers. 

What makes World App different from other digital wallets?

World App is designed to be used by everyone. 

For starters, World ID holders can enjoy gas-free transactions on World App. It also has a user experience that emphasizes simplicity and is intuitive for those who may never have engaged with crypto. Instead of giving people access to every advanced functionality, World App keeps its UX clean and intuitive by showing users only the parts of the Worldcoin and Ethereum ecosystems that are likely to be most helpful in their everyday lives.

At around 18MB, the native iOS and Android apps are significantly smaller than the industry average. To maximize inclusivity, they’re localized to multiple languages and support most active smartphones in the world (98.2% of Androids and 94.5% of iPhones), including some more than 10 years old. 

What protocols and APIs are integrated into World App?

World App leverages the composability of Ethereum to mix and match some of the best, most trusted open protocols and APIs into a single, easy-to-use app.

For example, World App wallets use account abstraction through SAFE contracts to increase security and enable gasless transactions. ENS usernames support friendly and easy peer-to-peer payments. Token trading is available through the Uniswap protocol, and Circle’s USDC enables users around the world to have always-on access to a fully-backed digital dollar. Frictionless fiat-to-crypto and crypto-to-fiat exchange in many countries is provided by licensed or registered partners around the world, including Ramp and MoonPay

In May, it was announced that Worldcoin’s World ID and TFH’s World App would be transitioned to the Optimism Mainnet. 

Where can I download World App?

World App is available in the App Store and the Google Play Store. It is currently available in most countries around the world.
