Welcome to Hyperlane! Here are some resources to help you get started building on the modular interoperability stack.
If you have deployed your own chain or rollup and want interoperability for that chain, you can deploy Hyperlane to your chain. Here's how:
Once Hyperlane exists on your desired chains, you can use one of the APIs provided. For each of the APIs, we have Quickstarts that folks can use to quickly try out the APIs and see how easy it is to use them. We highly recommend trying the quickstarts first to get a feel for the APIs before diving into the API reference pages.
You can use the accounts API to have an account make function calls on another chain. For example, a DAO can easily own assets on other chains without needing any remote smart contracts.
You can use the queries API to read state from a remote chain. For example, you can read a price feed or ENS name on Ethereum from BSC.
Anything that doesn't fit in the above, you can use Hyperlane messaging to send and receive arbitrary bytes between your contracts on different chains for maximum flexibility.

If you're running into issues once you've begun using Hyperlane, such as messages not getting processed or delivered properly, transaction failures, or other issues check out the Troubleshooting/Developer FAQ pages.
