The best-known chains built with Cosmos technology include the Cosmos Hub, dYdX Chain, Injective, Celestia and Cronos. Banks also use it: Wells Fargo uses Cosmos ledger technology for its tokenized deposit project.
As of September 2026, the Cosmos SDK’s maintainers count more than 200 chains built with it in production. Each chain runs its own validators and token, and many connect to each other through a messaging standard called IBC.
Cosmos is not a single blockchain. It is a set of open-source tools that teams use to build their own chains, called appchains. An appchain is a blockchain built for one application, such as an exchange.
The stack has three main parts:
IBC sees steady use. Map of Zones counted about 4 million IBC transfers worth roughly $2.2 billion across 90 active chains in the 30 days to September 28, 2026.
Several large networks run on the Cosmos SDK today, each for a different purpose.
The Cosmos Hub has been live since March 13, 2019. Its token, ATOM, is staked to secure the Hub and used for governance votes.
Stakers approved the Gaia v29 upgrade with 99.41% support and 49.59% turnout. The upgrade was scheduled for block 33,618,500 on October 28. It removes the x/params module and moves the Hub from Cosmos SDK v0.53.4 to v0.53.8. On October 30, Gaia developers began preparing a follow-up v29.1.0 upgrade that runs module migrations.
dYdX is a perpetual futures exchange that moved from an Ethereum layer 2 to its own blockchain. In June 2022, the team said no existing chain could handle the throughput its order book needed. It built a chain with the Cosmos SDK and CometBFT, which launched in October 2023, and wound down its old layer-2 exchange on October 28, 2024. The order book runs off-chain for speed, while trades settle on-chain. DYDX stakers earn a share of protocol fees paid in USDC.
Injective is a Cosmos SDK chain built around a native orderbook module, a built-in component for matching buy and sell orders. It also plays a growing role in the ecosystem’s stablecoin supply.
Circle is ending its support for Noble, the Cosmos chain that issued USDC. New USDC minting on Noble through Circle Mint stopped on October 13, 2026, and Circle plans to pause the Noble USDC contract and all CCTP routes on January 12, 2027.
On September 10, 2026, the Cosmos ecosystem chose Circle’s native USDC on Injective, called USDC.inj, as the replacement. The dYdX Foundation is working to make USDC.inj its sole eligible trading collateral but has not given a completion date, and it has told users not to send USDC.inj to dYdX until support is confirmed live.
Celestia is a modular blockchain network that provides data availability (DA) for other chains, such as rollups. It is built with its own fork of the Cosmos SDK, which it has maintained since 2021.
On October 15, 2026, Celestia moved that fork into a standalone GitHub repository with its full history. Its consensus node, celestia-core, is a fork of CometBFT. On October 20, Binary Builders, a former core maintainer team of the Cosmos SDK, announced it was shutting down, and most of its members joined Celestia.
Cronos EVM is an Ethereum-compatible chain built with the Cosmos SDK and Ethermint, and it has been live since November 8, 2021. It is part of the Crypto(.)com-linked Cronos family, which also includes the Cronos POS Chain, another Cosmos SDK chain used for CRO staking. Cosmos Labs has named Cronos as a performance partner, citing its early results with BlockSTM, a parallel transaction processing system the team is adding to the Cosmos SDK.
Cosmos tools are also being used by banks and large financial firms:
Not every chain stays. Sei, which was originally built with the Cosmos SDK, moved to an EVM-only design under SIP-3, a proposal its community approved in May 2025. Sei Labs set June 15, 2026 as the deadline for exchanges to move holdings to EVM addresses before Cosmos, CosmWasm and IBC functions were deprecated.
Akash Network, a decentralized cloud computing platform, is voting on Proposal #346 to move from its Cosmos chain to Solana. Support stood at about 98.29% on October 27, and voting closes on November 2 at 15:02 UTC. Akash cited operating costs under load as one of its main reasons for choosing Solana.
Cosmos technology runs more than 200 production chains, including the Cosmos Hub, dYdX Chain, Injective, Celestia and Cronos. The Cosmos SDK supplies the modules, CometBFT handles consensus and IBC moves tokens between about 90 active chains. Banks such as Wells Fargo and the Progmat consortium use it for tokenized deposits. Sei has left the stack and Akash is voting to leave, while ATOM trades near $1.47.
