ivem

Modern TypeScript SDK for the IOST blockchain — lightweight, composable, and type-safe.

Why ivem?

• Composable clients — Public client for queries, Wallet client for signing. Mix and match as needed.
• Type-safe from the ground up — Every action, account, and transport is fully typed.
• Familiar patterns — Inspired by modern web3 SDK design. If you've used viem, you'll feel right at home.

Quick Start

npm install @ivem/core

import { createPublicClient, http, mainnet } from "@ivem/core";

const client = createPublicClient({
  chain: mainnet,
  transport: http(),
});

const chainInfo = await client.getChainInfo();
console.log(chainInfo.head_block);
