The problem today is that while wallets are the most fundamental component required for using and adopting DeFi, Web3, crypto payments, a chain, and its ecosystem, they are one of the least well-developed applications in the crypto ecosystem. Wallets currently act mainly as an interface, serving primarily as a transaction signing layer, with very limited functionality or direct features/services/protocols (users generally have to search, find, learn, and interact with many different applications and services), and are generally lacking in basic UX, while providing very unprofessional, hard to use and aesthetically poor user interfaces, with most platforms built for developers rather than end users. This has been sufficient for early adopters in crypto. However, for the next billion users to onboard to DeFi and Web3, a more curated and high-quality user experience is required. Infinity Wallet steps in to fill this need as a one-stop hub for all payment, DeFi, NFT, and Web3 activity. Providing a unique all-in-one wallet and Web3 browser solution with a full spectrum of in-platform services, features, and protocols, focusing on delivering a premium platform and enhancing the user experience while providing a user-centric interface for a seamless decentralized user experience. They are streamlining accessibility and lowering the barrier to entry to allow for easy onboarding and true adoption of DeFi, crypto payments & Web 3.0 globally.

Web3 Wallets

In Web3, users have to maintain various addresses on multiple chains. This makes payments and interaction with Dapps very hard as the user has to use bridges multiple times, create new identities for multiple chains, probably buy different DIDs on various chains, and maintain native tokens on each chain. Because of all these, user has to jump multiple loops just to do a simple transaction. Also, Web3 doesn't have a request transaction feature yet; because of this, async payments and recurring payments are impossible to do today.

One of the core keywords in the current crypto market is cross-chain. While there are currently at least 100 active public chains, the number of bridges that connect these ecosystems is only about 50. Many of them only support 1 to 3 public chains.
