@avalanche-sdk/client/src/methods/pChain/getHeight.ts

A TypeScript SDK for interacting with the Avalanche network through JSON-RPC APIs. This SDK provides a comprehensive set of tools to interact with all Avalanche chains (P-Chain, X-Chain, C-Chain) and various APIs, including wallet functionality for transa
