The @zkp2p/contracts-v2 package provides minimal, network-specific ABIs extracted from on-chain deployments.

​
Import ABIs

Import ABIs for specific contracts on a network: 
import { Orchestrator, Escrow, UnifiedPaymentVerifier } from '@zkp2p/contracts-v2/abis/base';

// Use with ethers or viem
const orchestratorABI = Orchestrator;

​
Network-Specific ABIs

ABIs are organized by network to ensure compatibility: 
import { 
  Orchestrator, 
  Escrow, 
  UnifiedPaymentVerifier,
  AcrossBridgeHook 
} from '@zkp2p/contracts-v2/abis/base';

​

​
Using with ethers.js

​
Read Contract Data

import { ethers } from 'ethers';
import { base } from '@zkp2p/contracts-v2/addresses';
import { Orchestrator } from '@zkp2p/contracts-v2/abis/base';

const provider = new ethers.providers.JsonRpcProvider('https://mainnet.base.org');

const orchestrator = new ethers.Contract(
  base.Orchestrator,
  Orchestrator,
  provider
);

// Read contract state
const intentExpiration = await orchestrator.intentExpirationPeriod();
const takerFee = await orchestrator.takerFee();
const escrowAddress = await orchestrator.escrow();

​
Write to Contracts

import { ethers } from 'ethers';
import { base } from '@zkp2p/contracts-v2/addresses';
import { Orchestrator } from '@zkp2p/contracts-v2/abis/base';

const provider = new ethers.providers.Web3Provider(window.ethereum);
const signer = provider.getSigner();

const orchestrator = new ethers.Contract(
  base.Orchestrator,
  Orchestrator,
  signer
);

// Signal intent
const tx = await orchestrator.signalIntent(
  depositId,
  amount,
  to,
  paymentMethodHash,
  currencyHash,
  priceLimit,
  paymentIdentifier,
  encryptedPaymentDetails
);

await tx.wait();
console.log('Intent signaled:', tx.hash);

​
Using with viem

​
Read Contract

import { createPublicClient, http } from 'viem';
import { base as baseChain } from 'viem/chains';
import { base } from '@zkp2p/contracts-v2/addresses';
import { Orchestrator } from '@zkp2p/contracts-v2/abis/base';

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

const intentExpiration = await client.readContract({
  address: base.Orchestrator,
  abi: Orchestrator,
  functionName: 'intentExpirationPeriod',
});

​
Write Contract

import { createWalletClient, custom } from 'viem';
import { base as baseChain } from 'viem/chains';
import { base } from '@zkp2p/contracts-v2/addresses';
import { Orchestrator } from '@zkp2p/contracts-v2/abis/base';

const client = createWalletClient({
  chain: baseChain,
  transport: custom(window.ethereum),
});

const hash = await client.writeContract({
  address: base.Orchestrator,
  abi: Orchestrator,
  functionName: 'signalIntent',
  args: [
    depositId,
    amount,
    to,
    paymentMethodHash,
    currencyHash,
    priceLimit,
    paymentIdentifier,
    encryptedPaymentDetails,
  ],
});

​
Direct JSON Import

For bundle size optimization, import JSON files directly: 
import OrchestratorABI from '@zkp2p/contracts-v2/abis/base/Orchestrator.json';
import EscrowABI from '@zkp2p/contracts-v2/abis/base/Escrow.json';

const orchestrator = new ethers.Contract(
  address,
  OrchestratorABI,
  provider
);

​
Import All ABIs for a Network

Import all ABIs as a single object: 
import * as baseAbis from '@zkp2p/contracts-v2/abis/base';

console.log(baseAbis.Orchestrator);
console.log(baseAbis.Escrow);
console.log(baseAbis.UnifiedPaymentVerifier);

​
TypeScript Types

For TypeScript contract types, use the types export: 
import type { Orchestrator, Escrow } from '@zkp2p/contracts-v2/types';

// Use types for type-safe contract interactions
type OrchestratorContract = Orchestrator;

​
ABI Structure

ABIs follow the standard Ethereum ABI format: 
type ABI = Array<{
  type: 'function' | 'event' | 'error' | 'constructor';
  name?: string;
  inputs?: Array<{ name: string; type: string; internalType?: string }>;
  outputs?: Array<{ name: string; type: string; internalType?: string }>;
  stateMutability?: 'pure' | 'view' | 'nonpayable' | 'payable';
}>;
