ZetaChain Toolkit

ZetaChain Toolkit is a TypeScript SDK for building universal apps that transfer tokens, invoke contracts, and track transactions across any chain connected to ZetaChain.

✨ Features

• Cross-chain asset transfers: deposit gas and fungible tokens from any supported chain to ZetaChain and withdraw them back.
• Cross-chain contract execution: make incoming calls to universal contracts on ZetaChain or trigger outgoing calls to contracts on connected chains.
• Real-time transaction tracking: monitor the full lifecycle of cross-chain transactions as they propagate across networks.
• Built-in multi-chain support: works out of the box with EVM chains, Solana, Sui, Bitcoin, and TON.

📦 Installation

npm i @zetachain/toolkit

🚀 Quick start

import { evmDeposit, zetachainCall } from "@zetachain/toolkit";

// Deposit USDC from Ethereum to ZetaChain
await evmDeposit(
  {
    amount: "1.0",
    receiver: "0xReceiverOnZetaChain", // EOA or contract on ZetaChain
    token: "0xUSDC", // ERC-20 on the origin chain
  },
  { signer: ethersSigner }
);

// Ping a contract on Ethereum from ZetaChain
await zetachainCall(
  {
    receiver: "0xRecevierContract", // contract on a connected chain
    function: "hello(string)",
    types: ["string"],
    values: ["alice"],
    zrc20: "0xZRC20",
  },
  { signer: ethersSigner }
);

All Toolkit capabilities are also exposed through zetachain CLI.
