The Cosmos ecosystem operates differently from isolated blockchains. Instead of maintaining separate networks that cannot directly communicate, Cosmos chains use the Inter-Blockchain Communication protocol (IBC) to transfer assets and data between one another. This means a user holding tokens on Cosmos Hub, Osmosis, or Secret Network can move them directly without relying on centralized bridges or wrapped tokens. A keplr wallet download provides immediate access to this interconnected ecosystem from a single non-custodial application that stores private keys locally rather than on company servers.

But “access to the Cosmos ecosystem” remains vague for users new to IBC-enabled blockchains. The practical question is which chains Keplr supports, how to add new ones, and what assets can actually be held, staked, or exchanged across the network. This article covers the confirmed list of supported chains, the process for integrating custom or emerging blockchains, and the operational considerations that arise when managing a multi-chain portfolio from a single wallet interface.

The core Cosmos ecosystem chains supported by Keplr

Keplr wallet download enables immediate access to the foundation chains of the Cosmos network. Cosmos Hub is the primary chain, often referred to as the validator core of the ecosystem. It uses the ATOM token for staking and governance, and it serves as a settlement layer for IBC transactions. Users can store ATOM directly in Keplr and participate in validator delegation, earning rewards proportional to the amount staked and the validator’s commission.

Osmosis operates as the liquidity hub, running an automated market maker (AMM) protocol similar to Uniswap but designed specifically for the Cosmos ecosystem. Its native token, OSMO, is used for governance and liquidity provision incentives. Through Keplr, users can deposit assets into liquidity pools, receive LP tokens, and claim rewards without leaving the wallet interface. The network supports hundreds of trading pairs across IBC tokens, making it the primary venue for asset exchanges within Cosmos.

Juno is a smart contract platform running CosmWasm, enabling developers to write and deploy decentralized applications using WebAssembly. Its token, JUNO, is used for staking and governance. Secret Network extends this capability with encrypted smart contracts, allowing computation on sensitive data without exposing inputs or outputs. Akash offers decentralized cloud computing, Akt as the token, while Evmos bridges Cosmos and Ethereum ecosystems by supporting EVM applications on a Cosmos chain with IBC capabilities. Each chain has distinct use cases, but Keplr treats them as a unified portfolio accessible from one application.

Terra, the ecosystem’s largest by market cap at its peak, experienced governance and recovery phases. Luna 2.0 and UST derivatives now operate as separate entities, but they remain accessible through Keplr. Users familiar with Terra’s ecosystem should verify current chain status and asset availability before conducting large transactions, as post-collapse consolidation is ongoing.

IBC-enabled chains: The extended supported list

Beyond the core ecosystem, Keplr supports over 60 IBC-enabled blockchains, though the exact number fluctuates as new chains activate IBC capability. Stargaze is a dedicated NFT marketplace built on Cosmos with STARS as its token. Persistence operates as a lending and staking protocol. Gravity Bridge connects Cosmos to Ethereum through a validator set without requiring wrapped assets, enabling direct token movement between ecosystems. Each of these chains can be viewed and managed within a single Keplr wallet download without switching interfaces.

Chains like Kava, which operates as a multi-chain DeFi protocol, and Agoric, which uses JavaScript smart contracts rather than Rust or Solidity, showcase the diversity of the IBC ecosystem. Desmos, Chihuahua, Umee, Cronos (which has both EVM and Cosmos integration), and dozens of others each bring different protocols, tokens, and use cases. The IBC protocol itself is chain-agnostic; as long as two blockchains run compatible versions of the IBC standard, they can exchange assets directly.

Stride and Quicksilver are liquid staking protocols. Instead of locking tokens to earn staking rewards, users can deposit into these protocols and receive liquid staked derivatives that continue to appreciate while remaining tradeable. This provides capital efficiency—funds locked in staking remain productive in DeFi without waiting for an unbonding period. The derivative tokens (stATOM, stOSMO, qATOM, etc.) can then be used in liquidity pools or other protocols.

The practical implication is that a user holding ATOM can deposit it into Stride through Keplr, receive stATOM, and immediately use that stATOM in an Osmosis pool to earn trading fees while the underlying ATOM accrues staking rewards. This chain composition would be difficult or impossible to execute if the wallet did not natively support IBC transfers and direct dApp integration.

Adding custom or emerging IBC chains to Keplr

Not every IBC-enabled blockchain is pre-configured in Keplr at launch. New chains activate regularly, and users who want access before official integration can add custom chains manually. The process requires four pieces of information: the chain ID, the RPC endpoint URL, the REST endpoint URL, and basic currency configuration (ticker, decimal places, display precision). For most users, this information is published on the chain’s official documentation or community resources within hours of mainnet launch.

To add a custom chain, a user opens Keplr settings, selects the option to add a new chain, and enters the configuration details. Keplr then attempts to verify the chain ID and establish a connection. If successful, the wallet generates addresses on that chain using the same recovery phrase, allowing seamless participation as soon as the network confirms transactions. This means early adopters can begin staking or providing liquidity immediately upon a chain launch without waiting for Keplr’s development team to formally integrate it.

The risk is that incorrect endpoint configuration can cause transaction failures or misdirected funds. A user should verify RPC and REST endpoints through official channels, not through social media recommendations or unverified community sources. The same recovery phrase generates addresses across all added chains, so maintaining that phrase’s security is as important when exploring emerging networks as it is for the established ecosystem.

Some users create separate Keplr wallets for testnets or experimental chains. This compartmentalization can reduce risk if a new chain proves vulnerable or if its endpoints are compromised. However, it also increases the burden of managing multiple recovery phrases and potential confusion about which wallet holds which assets.

Hardware wallet integration and offline security

Keplr supports Ledger hardware wallets, allowing users to store private keys offline while still using the wallet’s interface to view balances, construct transactions, and access dApps. When a transaction requires signing, the Ledger device prompts confirmation. The private key never leaves the hardware wallet, and even if the connected computer is compromised, the attacker cannot drain funds without physical access to the device.

This integration spans every IBC-enabled chain that Keplr supports. A user can hold ATOM, OSMO, JUNO, and tokens from smaller chains all on a single Ledger, managing them through Keplr’s interface. Each chain’s address is deterministically generated from the Ledger’s seed phrase; the user can recover access using only the Ledger’s recovery phrase and any compatible wallet software.

The trade-off is operational friction. Staking, claiming rewards, or swapping tokens requires the Ledger to be connected and the transaction to be confirmed on the device screen. For users conducting frequent trades or testing many small transactions, this can be inconvenient. For users managing significant balances, the security benefit of offline key storage often justifies the slower transaction flow.

Standard Keplr installations without hardware wallet integration rely on the security of the device running the extension, mobile app, or web client. Biometric authentication on mobile devices (fingerprint or face recognition) adds a layer of protection, but it does not prevent loss if the device itself is stolen or the recovery phrase is compromised. The recovery phrase remains the ultimate secret; anyone with access to it can drain the wallet regardless of biometric locks.

Cross-chain asset movement and IBC transfers

Moving assets between IBC-enabled chains through Keplr is straightforward in concept but requires understanding network fees and confirmation times. To transfer ATOM from Cosmos Hub to Osmosis, a user selects the asset, specifies an IBC destination, and authorizes the transaction. Keplr calculates the network fee (usually a fraction of a cent), displays the receiving address on the destination chain, and broadcasts the transaction.

The transfer typically settles within a few blocks on each chain—usually within 30 seconds to a few minutes. If a chain experiences congestion or if validators are voting on important governance proposals, delays can extend slightly. However, IBC transactions are atomic; they either succeed completely or fail entirely, returning assets to the sender. Partial transfers or stuck assets are not expected under normal conditions.

The key operational consideration is that IBC addresses follow a specific format for each chain. An ATOM address on Cosmos Hub starts with “cosmos1”, while an OSMO address on Osmosis starts with “osmo1”. Sending to the wrong address format results in permanent loss. Keplr’s interface enforces address validation, refusing to send to incompatible formats, but a user should still verify addresses in full before confirming.

Gas fees for IBC transfers are higher than for simple transfers within a single chain because the transaction must be verified on both networks. A typical IBC transfer might cost 10,000 to 50,000 gas units, translating to $0.01 to $0.10 USD depending on network congestion and the receiving chain’s fee structure. This remains inexpensive compared to centralized exchanges, but it is significantly more than moving funds within a single network.

Staking, governance, and reward management across chains

Keplr’s staking interface simplifies delegation across multiple chains without requiring command-line tools or switching between wallets. A user can compare validator commissions, uptime percentages, and voting records directly in the app. Selecting a validator and entering a delegation amount triggers a transaction; the wallet signs and broadcasts it. Rewards accrue automatically and can be claimed with a single tap, though claiming incurs a gas fee to the network.

Governance participation is similarly integrated. When a chain holding assets in the user’s wallet posts a governance proposal, Keplr notifies the user and provides an interface to vote. The notification is optional and can be disabled, but it prevents governance events from being missed through simple inattention. A user holding both ATOM on Cosmos Hub and OSMO on Osmosis can participate in governance on both chains without external tools.

Reward compounding and tax accounting become more complex in a multi-chain environment. A user earning rewards on five chains receives five different tokens at five different rates, necessitating manual tracking or tax software integration. Keplr does not provide automated compounding or tax reporting. Users must manually claim rewards on each chain and reinvest them or sell them as appropriate. For those managing significant assets, this workflow benefit of a multi-chain wallet comes with a corresponding compliance burden.

Unbonding periods vary by chain. Cosmos Hub requires 21 days to unlock staked ATOM. Osmosis locks for 14 days. Other chains may have different parameters. The wallet displays these periods for each chain’s native token, but the user bears responsibility for understanding the lockup duration before deciding to undelegate.

NFT management and Web3 dApp integration

Keplr displays NFTs held across IBC-enabled chains, though support varies by chain. Stargaze is the primary NFT-focused ecosystem, and Keplr natively displays STARS NFTs with marketplace integration. Other chains supporting NFT standards can also show their collections, but the interface and transaction flow may be less polished than on Stargaze.

The wallet connects to decentralized applications built on Cosmos chains, enabling governance voting, liquidity provision on Osmosis, collateral deposits on lending protocols, and participation in yield farming. When a dApp requests connection, the user authorizes it within Keplr; the dApp then has permission to view the user’s address and request transaction signatures. Authorizations can be revoked in the wallet’s dApp settings.

This Web3 integration is both powerful and risky. A malicious dApp can request transactions that drain the wallet or steal NFTs. The wallet cannot prevent this; it can only display what is being signed. A user must verify transaction details before approving: the recipient, the token being sent, and the amount. The burden of verification falls entirely on the user; Keplr cannot distinguish between a legitimate dApp and a phishing clone with the same interface.

The practical defense is to limit dApp connections to known, reputable protocols and to verify any unusual requests. A dApp requesting permission to move NFTs that were not previously in the wallet, for example, signals potential compromise and should be rejected. Users with significant assets might maintain separate wallets for active dApp interaction and long-term storage.

Platform availability and installation security

Keplr is available as a Chrome extension, iOS app, Android app, and web-based platform. Each installation method has different security characteristics. The browser extension is the most widely used version and integrates most tightly with Cosmos dApps; however, browser compromises or malicious extensions can potentially observe activity or capture recovery phrases if stored insecurely. The mobile apps run in isolated operating system environments, providing better separation from other applications if the device is otherwise trusted.

Users conducting the keplr wallet download should verify the source carefully. The official Chrome extension is distributed through the Chrome Web Store; the official iOS app through the Apple App Store; the official Android app through Google Play. Third-party app stores or direct download links should be avoided unless verified through the official Keplr website. A counterfeit wallet can present itself identically to the legitimate version while stealing recovery phrases or signing transactions without user consent.

The web-based version at keplr.app requires no installation but should only be used on trusted devices. It carries the same compromise risks as the browser extension, with the added risk that the web server itself could be compromised or the connection could be intercepted if HTTPS is not properly verified.

After installation, the user creates a new wallet or imports an existing recovery phrase. The recovery phrase is the master secret; it must be written down, stored offline, and never entered into any online service except the wallet itself during account recovery. A user who has stored the recovery phrase in cloud notes, screenshots, or email has effectively handed the private keys to any service that accesses those backups.
