🌐 What Is Keplr Wallet Extension?

The Keplr Wallet Extension is a browser‑based crypto wallet that functions much like MetaMask—but for the Cosmos network and interoperable blockchains. Instead of just Ethereum‑based assets, Keplr lets you manage tokens, stake in Proof‑of‑Stake (PoS) chains, participate in governance, and interact with dozens of decentralized apps throughout the Cosmos Inter‑Blockchain Communication (IBC) network—all directly from your browser. (Keplr Wallet)

Key differentiators include:
✔ Multichain support across Cosmos and other IBC‑enabled chains
✔ Staking, delegation, and reward claiming
✔ Cross‑chain transfers and swaps
✔ Hardware wallet integration
✔ Seamless dApp connectivity
✔ Non‑custodial private key control (Keplr Wallet)

🧠 Core Features & Functionalities

🪙 1. Multichain Asset Management

Keplr brings multiple chains into a single interface so you don’t have to juggle wallets or manually switch between networks. Whether you hold ATOM (Cosmos Hub), OSMO (Osmosis), JUNO, or other IBC assets, Keplr gives a consolidated, transparent view of your portfolio. (Keplr Wallet)

What you can do:

• View balances across supported blockchains
• Add custom tokens by contract address
• Track on‑chain activity and history
• Monitor price performance and staking stats (Keplr Wallet)

🔁 2. Cross‑Chain Transfers & Swaps

Keplr is built on the Cosmos IBC standard, meaning you can transfer assets between chains without relying on centralized bridges. Within the extension, cross‑chain transfers and cross‑chain swaps are available, making liquidity more accessible and saving on fees. (Keplr Wallet)

📊 3. Staking, Delegation & Rewards

One of Keplr’s flagship features is staking support. You can delegate tokens like ATOM to validators, help secure the network, and earn staking rewards—all without leaving the extension interface. Reward claiming is streamlined, and Keplr shows unbonding periods and validator performance. (Keplr Wallet)

🚀 4. Seamless dApp Interaction

When visiting compatible dApps (e.g., Osmosis, Juno, or other Cosmos‑native applications), the Keplr Wallet automatically connects. You’ll be prompted to grant permissions, sign transactions, and participate in on‑chain activities without repeatedly exporting and importing keys. (Keplr Wallet)

🔐 5. Enhanced Security & Non‑Custodial Control

Keplr is a non‑custodial wallet—you and only you control your private keys. These keys are encrypted and stored locally on your device. That means no third party can access your funds, but it also means you are responsible for keeping your recovery phrase safe. (Keplr Wallet)

Security features include:

• Encrypted key storage
• Optional hardware wallet integration (e.g., Ledger)
• Permission management and session control
• Auto‑lock timers and privacy settings (Keplr Wallet)

🧩 6. Side Panel Mode (New UX Feature)

Keplr recently introduced Side Panel Mode for Chrome, allowing the wallet to stay open alongside your browsing window. This enables easier portfolio monitoring and smoother transaction signing without managing pop‑ups. (Keplr Wallet | Official Support)
