NodeJS SDK

PreviousRouterNextRPC Providers

Last updated 1 year ago

Note: Abacus is the former name of the Hyperlane protocol. The repos will soon be renamed.

The NodeJS SDK (@hyperlane-xyz/sdk) contains everything you need to productionize your interchain app on the web, including:

RPC Provider Management

App to chain communication is performed via ethers.js compatible providers. To help manage providers for multiple chains, the SDK includes a MultiProvider utility.

Multichain Deployment Tooling

Facilitate deploying your contract(s) to multiple chains. This includes utilities for bytecode verification, contract upgradability patterns, and resumability from partially successful deployments (e.g. k/n chains successfully deployed).

Interchain Gas Estimation

Hyperlane allows users to pay for message processing on the destination chain using tokens from the origin chain. Use the InterchainGasCalculator utility for gas estimation of interchain messages.
