cnft.createContract(CreateContract)

Create a Contract NFT draft by initializing the contract with counterparties and content, and paying the setup fee (ERC20). This sends a transaction from the contract controller.

​
CreateContract Type Parameters

ParameterTypeRequiredDescription
contractControllerSignerRequiredSigner that controls the contract and submits the transaction. Must be connected to a provider.

tokenDecimalsnumberRequiredERC20 token decimals for human-readable fee amounts.
counterpartiesstring[]RequiredArray of counterparty EOA addresses that must sign the contract.
contractNftstringRequiredContract NFT contract address.
contractHashstringRequiredContent hash (e.g., keccak256 of the contract content).
urlstringRequiredURL pointing to the contract content/metadata.

​
Returns

FieldTypeDescription
statuscreatedStatus of the operation.

counterpartiesstring[]Counterparty addresses included in the draft.
content{ hash: string; url: string }Content hash and URL.
fee{ token: string; tokenDecimals: number; setupAmount: bigint; balanceBefore: bigint; balanceAfter: bigint; humanTokenDelta: string }Fee and ERC20 balance details for the setup.
receiptTransactionReceiptTransaction receipt for the creation call.

Usage

TypeScript

import 'dotenv/config';
import { RWA, Chain, type SDKInit } from '@peaq-network/rwa';
import { JsonRpcProvider, Wallet, keccak256, toUtf8Bytes } from 'ethers';

async function main() {
  // 0. Create RWA instance and get provider
  const provider = new JsonRpcProvider(process.env.HTTPS_BASE_URL);
  const init: SDKInit = { chainId: Chain.AGUNG, provider: provider };
  const rwa_sdk = new RWA(init);

  // 1. Contract controller (submits tx and pays ERC20 fee)
  const alice = new Wallet(process.env.ALICE_PRIVATE_KEY!, provider);

  // 2. Counterparties
  const bob = process.env.BOB_PUBLIC_ADDRESS!;
  const charlie = process.env.CHARLIE_PUBLIC_ADDRESS!;

  // 3. Prepare content
  const contractNft = "0x35D67095A5a6f00CBE288cF744b3efC48de3699a";
  const url = "https://example.com";
  const content = `This is a test contract ${Date.now()}`;
  const contractHash = keccak256(toUtf8Bytes(content));

  // 4. Create contract draft
  const result = await rwa_sdk.cnft.createContract({
    contractController: alice,
    erc20: rwa_sdk.getAddresses().erc20.peaq,
    tokenDecimals: 18,
    counterparties: [bob, charlie],
    contractNft: contractNft,
    contractHash: contractHash,
    url: url
  });
  console.log("Result", result);
}
