@avakit/core

Framework-agnostic kernel for AvaKit — EVM clients, wallet adapters, deploy helpers, and chain data for Avalanche. Depends only on viem. AvaKit never touches private keys.

Install

npm install @avakit/core viem

ESM-only. @avakit/core ships ES modules (no CommonJS build) — use import, not require. In a CommonJS file, load it with a dynamic await import("@avakit/core"). Requires Node >= 20.11.

Usage

import { fuji, getPublicClient, getBalance, injectedAdapter } from "@avakit/core";

// Read chain data
const balance = await getBalance("0x…", fuji);

// Connect a wallet (browser)
const adapter = injectedAdapter();
const { address, provider } = await adapter.connect();

Chains live at @avakit/core/chains; the optional Web3Auth social-login adapter at @avakit/core/web3auth.

What's inside

• Chains — fuji, cChain, defineChain for custom L1s
• Clients — getPublicClient, getWalletClient, toViemChain
• Adapters — injectedAdapter() (Core / MetaMask); web3authAdapter({ clientId }) (social login, from @avakit/core/web3auth)
• Network — ensureChain(provider, chain) (add + switch)
• Deploy — deployContract, getBytecode
• RPC data — getBalance, getTransactionReceipt, readContract (take an AvaChain)
• Indexed data (AvaCloud) — getNativeBalance, listErc20Balances, listNfts, listTransactions (take an address + a chain, either an AvaChain like fuji or a raw chain id like 43113)
