Answering the most frequently asked questions about all things Hyperlane
Hyperlane is the first universal and permissionless interoperability framework built for the modular blockchain stack.
Anyone can Deploy Hyperlane to any blockchain environment, whether it is a layer 1, rollup, or app-chain, allowing that chain to communicate seamlessly with any other chain on which Hyperlane has been deployed.
Hyperlane offers benefits for both blockchain and dapp developers.
For blockchain developers, a Hyperlane deployment expands accessibility to users, assets, and valuable state from other connected blockchains on which Hyperlane has been deployed.
For dapp developers, Hyperlane provides seamless connectivity across multiple blockchains, allowing developers to create interchain network effects and liquidity and users to interact with applications from their preferred chain.
Hyperlane is secured by its modular security stack featuring Interchain security modules (ISMs). Developers can configure various pre-built ISMs, compose them with each other, or even create custom ISMs based on their application's needs.
A modular approach to security ensures that Hyperlane will continue to stay up to the latest industry advances in security models.
There is no protocol-enshrined security model, let alone validator set. That said, most Hyperlane deployments are configured with a Default ISM, which specifies the security model to use if the message recipient has not specified an ISM override. See Default ISM settings for more information
Hyperlane's Messaging API allows dapp developers to send arbitrary bytes between smart contracts on different chains. This can be used to create interchain applications, dapps which span multiple chains.
For inspiration, take a look at some of the pre-built applications built on top of Hyperlane, including:
- 1.An application calls the
dispatch()function on the origin chain, inserting the message into the Mailbox's Merkle tree.
- 2.Hyperlane Relayers observe the dispatched messages and assemble metadata for the recipient's Interchain Security Module (ISM)
- 3.A relayer delivers the message to the recipient by calling
Mailbox.process(). The Mailbox verifies the message with the recipient’s ISM, and calls
recipient.handle()to deliver the message.
Paste an address or transaction hash into the search bar of the Hyperlane Message Explorer to view details about a message’s status and history.
If the message has failed to send for some reason, there will be error messages indicating what may have gone wrong. See Troubleshooting for more information on how to debug an undelivered message
Hyperlane is a protocol designed to allow smart contracts on different chains to interact with each other.
Not exactly. Hyperlane is a protocol that allows communication between blockchains.
Token bridges are just one of many types of applications that can be built on top of Hyperlane! For more ideas what can be built on Hyperlane check out What can I build with Hyperlane?
