Legacy SDK

Many applications using wormhole may require a frontend to interact with the underlying smart contracts.

Wormhole provides an SDK with utilities for developers that includes:

• Tools for parsing VAAs and other Wormhole structures.

• Methods for interacting with the Token and NFT bridges.

• Methods for submitting messages and parsing Wormhole contract output.

Installation

The SDK can currently be found in the core wormhole repository here and is available on npm.

The SDK can be installed using npm:

npm i @certusone/wormhole-sdk

Configuration

These RPC nodes are maintained by the Guardians to help fetch VAAs and query the Wormhole network.
