How do I connect a Keplr wallet using Cosmos Kit?

Install the @cosmos-kit/react package and use the useWallet hook or provided components. The documentation includes examples for initializing the adapter with Keplr and other supported wallets.

Should I use Cosmos Kit or interchain-kit for my new project?

For new projects, interchain-kit is recommended as it's the official successor with broader Interchain ecosystem support. Cosmos Kit is better suited for maintaining existing Cosmos-specific applications that don't need future updates.

Does Cosmos Kit support mobile wallets?

Yes, it includes WalletConnect support via the @cosmos-kit/walletconnect package, allowing connections with mobile wallets that are compatible with the Cosmos ecosystem, such as through QR codes.

How can I get a CosmJS signer with Cosmos Kit?

Use the hooks provided in the documentation to retrieve CosmJS signers for Stargate or CosmWasm. This enables signing transactions directly, but requires proper configuration of chain information and wallet connections.

Can I use Cosmos Kit with Vue.js or Svelte?

While optimized for React, the core packages and 'vanilla' example demonstrate how to integrate with other frameworks, but it involves more manual setup and lacks out-of-the-box components for non-React environments.

Is Cosmos Kit still actively maintained?

The GitHub shows recent activity with tests and badges, but the README's upgrade notice to interchain-kit suggests that active development has shifted, so long-term maintenance for Cosmos Kit is uncertain.

What is cosmos-kit?

Cosmos Kit is a universal wallet adapter for developers building applications that interact with Cosmos blockchains. It provides a single interface to connect with multiple Cosmos wallets like Keplr, Leap, and Cosmostation, simplifying wallet integration and blockchain interactions.

Target Audience

Developers building decentralized applications (dApps) on Cosmos blockchains who need to integrate wallet connectivity and blockchain interactions.

Value Proposition

Developers choose Cosmos Kit because it offers a unified wallet adapter with broad wallet support, React integration for easy implementation, and modular packages that allow customization while reducing development complexity.

Overview

Universal wallet connector for the Cosmos ⚛️

Use Cases

Best For

Building dApps that need to connect with multiple Cosmos wallets
React developers creating Cosmos blockchain applications
Projects requiring mobile wallet support via WalletConnect
Teams needing modular wallet adapter components
Applications that integrate with CosmJS for signing operations
Developers using the Interchain JavaScript stack

Not Ideal For

Projects targeting non-Cosmos blockchains like Ethereum or Solana
Applications that don't require user wallet interactions or authentication
Teams using frontend frameworks other than React without readiness for custom integration work
New development initiatives, as the project recommends using its successor, interchain-kit, for ongoing support

Pros & Cons

Pros

Broad Wallet Compatibility

Supports over a dozen wallets including Keplr, Leap, and Cosmostation, with WalletConnect for mobile, as listed in the wallets directory.

Seamless React Integration

Provides pre-built React hooks and components like the Interchain UI Modal, making wallet connection straightforward for React developers.

Modular Package Design

Offers separate packages for core, React, and wallet-specific adapters, allowing for lightweight and customizable installations.

CosmJS Signer Support

Integrates directly with CosmJS for Stargate and CosmWasm signing, enabling complex blockchain operations without extra setup.

Cons

Impending Obsolescence

The README explicitly warns to upgrade to interchain-kit, indicating that Cosmos Kit may be deprecated and lack future updates or new features.

Configuration Overhead

The modular architecture with multiple packages (e.g., core, react, walletconnect) requires managing dependencies, complicating initial setup compared to all-in-one solutions.

External Documentation

Relies on external docs hosted at docs.hyperweb.io, which might not be synchronized with the latest code changes, leading to potential integration issues.
