# Cross-chain Interoperability using Celer ## Overview [Celer Network](https://www.celer.network/) is a leading multi-chain interoperability protocol supporting fungible tokens, NFT, and generic message transfers and bridging across multiple blockchains. [Celer cBridge](https://cbridge-docs.celer.network/) is a decentralized and non-custodial asset bridge enabling a one-click user experience when transferring tokens and NFTs across multiple chains. Powered by the [Celer Inter-chain Message Framework](https://im-docs.celer.network/developer/celer-im-overview), cBridge has processed over $15b in cross-chain asset transfers across 40+ blockchains. All while it continues to quickly grow and expand by supporting more blockchains and layer-2s. Celer is capable of supporting various bridge scenarios to enable asset and message transfers across rollups, primary chain, or any other blockchains in terms of these types of bridges: * Fungible Token Bridging: [canonical mapping bridge](https://docs.google.com/document/d/1w4vPpXYLxTjnR-H5sc5B3XD9Juxph8KnebZfH5zs0rI/edit#bookmark=id.bc65i22xtu0f) * Non-fungible Token Bridging: [pegged NFT bridge](https://docs.google.com/document/d/1w4vPpXYLxTjnR-H5sc5B3XD9Juxph8KnebZfH5zs0rI/edit#bookmark=id.yrcqrt7wpoei) and [multi-chain native (MCN) NFT bridge](https://docs.google.com/document/d/1w4vPpXYLxTjnR-H5sc5B3XD9Juxph8KnebZfH5zs0rI/edit#bookmark=id.o6ak928sasv0) * Generic Message Passing --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
