The Open Standard for Secure Interoperability
Connect your digital ledger] on the secure, permissionless, and feature-rich blockchain interoperability protocol. to hundreds of networks with secure, neutral, open source interoperability, including Hyperledger Besu, Ethereum, Solana, and Cosmos.
Universal Interoperability
Networks that implement the IBC standards can interoperate with each other, enabling cross-ledger workflows for use cases like asset transfers, data sharing, business process automation, and more.
Permissionless Access
IBC is open source. There are no fees or costs to use IBC.
Robust Security
IBC’s light client-based direct verification removes the need for a third-party intermediary in cross-ledger interactions. Verification can be tailored to different security requirements, using Attestors for permissioned networks and consensus or zero-knowledge (ZK) light clients for permissionless networks.
IBC-Powered Ledgers
Join the IBC ecosystem of interoperable ledgers and applications.
Public Network Size
IBC is one of the most widely-adopted blockchain interoperability standards across digital ledger networks.
The IBC network has over 35M annual cross-chain transactions on average.
IBC-enabled chains and ecosystems have a market cap of approximately $58B+.
IBC is part of the
Cosmos Stack
Development and maintenance is funded by the Interchain Foundation and hundreds of independent developers contribute to the protocol on a volunteer basis.
Today, IBC has flourished into a network of networks, averaging 2 million Monthly Active Users.
Build without Boundaries
IBC offers industry-leading features for robust cross-chain workflows.
Asynchronous Communication

Integrating the IBC solo machine client has been a game-changer for us. It effortlessly allowed us to mint pegged DOT and various other tokens, all without the hassle of setting up an entire blockchain.

We have long believed that IBC will become the de facto standard for blockchain interoperability. This conviction has driven us to contribute to IBC, particularly by extending its availability to non-Cosmos blockchains, including EVMs and enterprises. Ibc-solidity is one such implementation we kickstarted. We view IBC as an indispensable technology. It is the foundation for our trust-minimized cross-chain bridge.
