Cosmostation

Cosmostation is a Seoul-based blockchain infrastructure company founded in 2018 with a focus on the proof-of-stake ecosystem. Over eight years the team built a vertically integrated stack covering validator node operations, a multi-chain block explorer, and a self-custodial wallet. The company describes its mission as providing seamless access to the interchain ecosystem and has contributed to more than fifty protocols.

Validator Infrastructure

Cosmostation's core business is running validator nodes. The company served as a genesis validator on more than eighty proof-of-stake blockchain networks and, by 2023, reported securing over sixty chains built with the Cosmos SDK through its infrastructure operations. Validated networks include the Cosmos Hub, Osmosis, Kava, Cronos, Evmos, Band Protocol, Iris Hub, Persistence, and Shentu Chain, among many others. The validator operation collectively held more than 120 million dollars in staked assets across these chains.

The company's validator presence is tracked publicly on its own Mintscan explorer. Users can view Cosmostation's voting power, commission rates, and uptime history directly on the platform at mintscan.io/visualization/validators/cosmostation.

Mintscan: Multi-Chain Block Explorer

Mintscan is Cosmostation's flagship developer and end-user product. The explorer covers 63 or more blockchains and provides transaction history, block data, staking analytics, governance tracking, and IBC (Inter-Blockchain Communication) transfer monitoring. A Mintscan 2.0 redesign introduced a unified interface for navigating assets and activity across all supported networks from a single dashboard.

For IBC-connected networks, Mintscan surfaces relayer data and channel health, making it a practical tool for developers and delegators managing positions across multiple Cosmos SDK chains. The explorer remains active and is the product most likely to outlast Cosmostation's other consumer-facing offerings.

Cosmostation Wallet — Discontinued September 2026

For several years Cosmostation maintained a self-custodial multi-chain wallet available on iOS, Android, and as a Chrome extension. The wallet supported 80 or more networks, combining Cosmos SDK chains with EVM-compatible networks including Polygon and Optimism, and covered core functions such as staking, governance participation, and asset management.

On September 1, 2026, Cosmostation retired the wallet across all platforms. Following that date, only recovery phrase and private key export functions remain active; staking, governance, and transfer features are no longer accessible through the app. Because the wallet was non-custodial, user assets remain on their respective blockchains and are not held by Cosmostation. The company directed affected users to export their recovery phrases before the cutoff and import them into a compatible alternative such as Keplr or Leap.

The stated reason for the discontinuation was a strategic refocus on core infrastructure — Mintscan and validator services — rather than consumer wallet products. Cosmostation confirmed that its infrastructure operations continue unaffected by the wallet closure.

Interchain Expansion and IBC

Cosmostation's validator and explorer work has historically been concentrated in the IBC-connected Cosmos ecosystem. IBC (Inter-Blockchain Communication) enables trust-minimized asset transfers between Cosmos SDK chains and, more recently, is being extended to external networks. IBC Eureka, launched in April 2025, extended IBC beyond Cosmos for the first time by using zero-knowledge proof verification to connect Cosmos chains directly to Ethereum. Solana and Layer-2 integrations were in advanced development as of early 2026. While Cosmostation does not operate a standalone Solana validator, its infrastructure and tools are positioned within the IBC-connected interchain that is actively working toward Solana connectivity.

The 2026 Cosmos Stack roadmap targets Solana and EVM/L2 light client support and a general IBC solution that would allow assets to move between Solana and Cosmos chains in a trust-minimized way — a development that would place Cosmostation's validator and explorer infrastructure directly in a broader Solana-adjacent ecosystem.

GitHub and Open Source

Cosmostation maintains an active open-source presence at github.com/cosmostation. Notable repositories include the Cosmos Validator Monitoring Service (CVMS), pharos-monitoring tooling, and the monad-exporter. The organization has contributed to the broader Cosmos developer ecosystem over multiple years.

Current Status

As of September 2026, Cosmostation remains an active infrastructure company. Its wallet product has been wound down, but the Mintscan block explorer and validator node operations continue. The company holds a significant historical position in the Cosmos ecosystem as a genesis validator for a large portion of its PoS networks and as the team behind one of the ecosystem's most widely used explorers.
