BTP is ICON's bespoke cross-chain communication protocol for heterogeneous blockchains, while IBC is a protocol that connects through smart contracts. Currently, chains supported by BTP are ICON, Havah, Ethereum, and Binance Smart Chain, while chains supported by IBC are ICON and Archway.

The ICON Bridge is a centralized bridge for the Blockchain Transmission Protocol (BTP) Relay System, which can be used to transfer tokens across multiple chains. It currently supports cross-chain transfers from ICON and Binance Smart Chain (BSC).

ICON is a community-run organization where community members with raised roles and responsibilities, called delegates, are responsible for proposing changes to improve network state based on current context and future goals. Delegates are selected by the community through voting.

ICON's Cross-Chain Framework allows apps to transform from isolated and ineffective to well-connected and essential, avoiding both a declining user base and long development integration timelines. Apps, written in any programming language, can use the ICON Cross-Chain Framework to access the diverse features and user bases of a broad community of blockchains.
