createEscrow(receiver, amount, deadline)
Create new escrow. Returns escrowId. // Using viem/wagmi await writeContract({ address: '0x6354869F9B79B2Ca0820E171dc489217fC22AD64', abi: ESCROW_ABI, functionName: 'createEscrow', args: [ '0xRECEIVER_ADDRESS', // address receiver parseUnits('100', 6), // uint96 amount (USDC 6 decimals) Math.floor(Date.now()/1000) + 86400 // uint40 deadline (24h) ] });
release(escrowId)
Sender releases payment early (manual approval). await writeContract({ address: ESCROW_ADDRESS, abi: ESCROW_ABI, functionName: 'release', args: [BigInt(escrowId)] });
autoRelease(escrowId)
Anyone can call after deadline + 1 hour inspection period. // First check if ready const ready = await readContract({ address: ESCROW_ADDRESS, abi: ESCROW_ABI, functionName: 'canAutoRelease', args: [BigInt(escrowId)] }); if (ready) { await writeContract({ address: ESCROW_ADDRESS, abi: ESCROW_ABI, functionName: 'autoRelease', args: [BigInt(escrowId)] }); }
cancel(escrowId)
Sender cancels within first 30 minutes. await writeContract({ address: ESCROW_ADDRESS, abi: ESCROW_ABI, functionName: 'cancel', args: [BigInt(escrowId)] });
dispute(escrowId)
Either party flags for arbitration. await writeContract({ address: ESCROW_ADDRESS, abi: ESCROW_ABI, functionName: 'dispute', args: [BigInt(escrowId)] });
Create Multiple Escrows
41% gas savings vs individual transactions. await writeContract({ address: ESCROW_ADDRESS, abi: ESCROW_ABI, functionName: 'createEscrowBatch', args: [ [addr1, addr2, addr3, addr4, addr5], // address[] receivers [100e6, 200e6, 150e6, 300e6, 250e6], // uint96[] amounts [deadline1, deadline2, deadline3, deadline4, deadline5] // uint40[] deadlines ] });
Release Multiple Escrows
35% gas savings vs individual transactions. await writeContract({ address: ESCROW_ADDRESS, abi: ESCROW_ABI, functionName: 'releaseBatch', args: [[id1, id2, id3, id4, id5]] });
getEscrow(escrowId)
Get escrow details. const escrow = await readContract({ address: ESCROW_ADDRESS, abi: ESCROW_ABI, functionName: 'getEscrow', args: [BigInt(escrowId)] }); // Returns: [sender, receiver, amount, createdAt, deadline, state] // state: 0=Active, 1=Released, 2=Disputed, 3=Refunded, 4=Cancelled
canAutoRelease(escrowId)
Check if ready for auto-release. const ready = await readContract({ address: ESCROW_ADDRESS, abi: ESCROW_ABI, functionName: 'canAutoRelease', args: [BigInt(escrowId)] }); // Returns: boolean
getEscrowBatch(escrowIds[])
Efficient batch view (gas optimized). const result = await readContract({ address: ESCROW_ADDRESS, abi: ESCROW_ABI, functionName: 'getEscrowBatch', args: [[id1, id2, id3, id4, id5]] }); // Returns: [states[], amounts[]]
Complete Workflow Example
import { createPublicClient, createWalletClient, http } from 'viem'; import { baseSepolia } from 'viem/chains'; import { privateKeyToAccount } from 'viem/accounts'; const ESCROW_ADDRESS = '0x6354869F9B79B2Ca0820E171dc489217fC22AD64'; const USDC_ADDRESS = '0x036CbD53842c5426634e7929541eC2318f3dCF7e'; const account = privateKeyToAccount('0xYOUR_PRIVATE_KEY'); const walletClient = createWalletClient({ account, chain: baseSepolia, transport: http() }); const publicClient = createPublicClient({ chain: baseSepolia, transport: http() }); // 1. Approve USDC const approveTx = await walletClient.writeContract({ address: USDC_ADDRESS, abi: [{ name: 'approve', type: 'function', inputs: [ { name: 'spender', type: 'address' }, { name: 'amount', type: 'uint256' } ], outputs: [{ name: '', type: 'bool' }], stateMutability: 'nonpayable' }], functionName: 'approve', args: [ESCROW_ADDRESS, parseUnits('100', 6)] }); await publicClient.waitForTransactionReceipt({ hash: approveTx }); // 2. Create escrow const createTx = await walletClient.writeContract({ address: ESCROW_ADDRESS, abi: ESCROW_ABI, functionName: 'createEscrow', args: [ '0xRECEIVER_ADDRESS', parseUnits('100', 6), Math.floor(Date.now()/1000) + 86400 ] }); const receipt = await publicClient.waitForTransactionReceipt({ hash: createTx }); console.log('Escrow created:', receipt.transactionHash); // 3. Later: Release payment const releaseTx = await walletClient.writeContract({ address: ESCROW_ADDRESS, abi: ESCROW_ABI, functionName: 'release', args: [escrowId] }); await publicClient.waitForTransactionReceipt({ hash: releaseTx }); console.log('Payment released!');
