Definitions

At a high level, bridges offer the following features:
FeatureDescription
Arbitrary Messaging Bridge (AMB)Allows arbitrary messages to be securely relayed from a smart contract on chain 1 to a smart contract on chain 2.

AMB provides guarantees that messages delivered to chain 2 represent events finalized on chain 1.
Token BridgeAllows user to lock native tokens or ERC20 tokens on chain 1 and mint claim tokens on chain 2.

Bridge maintains the invariant that, for each token minted on chain 2, there exists a corresponding token locked on chain 1.
Intents Bridge / Liquidity LayerAllows user to turn in tokens on one chain and quickly redeem tokens on another chain, typically relying on drawing on a pool of assets maintained on each side. Provides greater immediacy relative to waiting for full finality of an AMB.
Bridge AggregatorAggregates multiple liquidity layers or token bridges, potentially integrating swapping as well so that users may receive a different token than the one they input.
Chain AbstractionEnables a user experience exempt from the manual processes required to interact with multiple chains.

ChangeHero

ChangeHero is a cross-chain swap platform enabling frictionless asset exchanges across a wide range of networks. Leveraging aggregated liquidity and optimized routing logic, it delivers fast settlement and consistent pricing for any supported pair. Its clean integration pathways and dependable execution make ChangeHero a straightforward tool for powering multi-chain swaps within decentralized applications. To learn more, check out the docs. Chainlink Cross-Chain Interoperability Protocol (CCIP) is the standard for cross-chain interoperability. CCIP enables developers to build secure cross-chain apps that can transfer tokens, send messages, and initiate actions across blockchains. Through the Cross-Chain Token (CCT) standard, CCIP enables token developers to integrate new and existing tokens with CCIP in a self-serve manner in minutes, without requiring vendor lock-in, hard-coded functions, or external dependencies that may limit future optionality. CCTs support self-serve deployments, full control and ownership for developers, zero-slippage transfers, and enhanced programmability via configurable rate limits and reliability features such as Smart Execution. CCIP is powered by Chainlink decentralized oracle networks (DONs)—a proven standard with a track record of securing tens of billions of dollars and enabling over $19 trillion in onchain transaction value. Key CCIP developer tools:
  • CCIP official documentation: start integrating CCIP into your cross-chain application.
  • CCIP Token Manager: an intuitive front-end web interface for the deployment of new and management of existing CCTs by their developers, including no-code guided deployments and configuration tools.
  • CCIP SDK: a software development kit that streamlines the process of integrating CCIP, allowing developers to use JavaScript to create a token transfer frontend dApp.
