Architect Pay Docs

Overview

Architect Pay is an on-chain payroll and payments platform built on the Arc blockchain. It uses Circle's Developer-Controlled Wallets (SCA — ERC-4337 Smart Contract Accounts) so users never manage seed phrases, and Circle's Gas Station sponsors all transaction fees.

Arc is the settlement hub. A deposit on any supported chain is consolidated onto Arc automatically, and every payout is routed from there — Circle quotes Arc at zero basis points outbound to every destination, where routing chain-to-chain directly costs more. Users see one USDC balance and one EURC balance and never choose a source chain; they choose who to pay and which chain that person receives on.

Quick Start

1. 1
   Create an account

   Sign up at architectpay.website/signup. A Circle SCA wallet is provisioned instantly on Arc and every supported chain.

2. 2
   Fund your wallet

   Go to your Dashboard and click Deposit, then pick the chain you are sending from — Arc, Base, Arbitrum, Polygon, Avalanche or Optimism. Funds are spendable on arrival and settle onto Arc in the background, usually within a minute for USDC and up to 20 for EURC.

3. 3
   Send a payment

   Go to Send Payment, pick the token and the chain your recipient receives on, enter their address and confirm. You never pick a source chain — the payment is funded from your balance.

4. 4
   Run payroll

   Add employees under the Payroll tab with their wallet address and salary. Click Run Payroll — the platform batches all payments in parallel.

Payments API

Send USDC or EURC to any EVM address on any supported chain. Same-chain payments use Circle's transfer API directly. Cross-chain payments use Circle CCTP.

POST /api/payments/send

{
  "recipientAddress": "0xABC...",
  "amount": "10.00",
  "sourceChain": "ARC-TESTNET",
  "destChain": "BASE-SEPOLIA",
  "token": "USDC",
  "label": "Invoice #42"
}

// Response (cross-chain)
{
  "success": true,
  "paymentId": "clx...",
  "pending": true         // poll /api/payments/{id}/mint
}

// Response (same-chain)
{
  "success": true,
  "paymentId": "clx..."
}

For cross-chain transfers, poll POST /api/payments/{id}/mint every 10s until status is COMPLETED.

Payroll

Add employees once and run payroll at any time. You can also schedule automatic monthly runs.

// Add an employee
POST /api/employees
{
  "name": "Alice Smith",
  "walletAddress": "0xABC...",
  "salary": "3000.00"
}

// Run payroll immediately
POST /api/payroll/run

// Get payroll history
GET /api/payroll/runs

Cross-Chain CCTP

Cross-chain movement uses Circle's Cross-Chain Transfer Protocol V2 for USDC, and CCTPx for EURC. The flow has two phases either way: burn on the source chain, mint on the destination. This runs in two places — consolidating a deposit onto Arc, and paying out from Arc to a recipient's chain.

Swaps

Swap USDC ↔ EURC against your balance. Swaps execute on Arc, where every balance settles, so there is no chain to choose.

POST /api/swap

{
  "tokenIn": "USDC",
  "tokenOut": "EURC",
  "amountIn": "100.00",
  "srcChain": "ARC-TESTNET",
  "destChain": "ARC-TESTNET"
}

GET /api/swap/history
