Fund Your Project

Before your agent can make payments, the project needs a funded USDC balance. There are two ways to add funds: deposit USDC directly on-chain (recommended) or send fiat via a virtual bank account.

Method 1: On-Chain USDC Deposit

The fastest way to fund your project. Send USDC on the Base network directly to your project’s wallet address.

Get Your Deposit Address

Retrieve your project’s deposit address via the API or from the project dashboard at app.unwall.xyz.

curl https://api.unwall.xyz/v1/stablecoin/address \
  -H "Authorization: Bearer aw_live_xxxxxxxxxxxx"

import requests

headers = {"Authorization": "Bearer aw_live_xxxxxxxxxxxx"}
response = requests.get("https://api.unwall.xyz/v1/stablecoin/address", headers=headers)
print(response.json())

const response = await fetch("https://api.unwall.xyz/v1/stablecoin/address", {
  headers: { Authorization: "Bearer aw_live_xxxxxxxxxxxx" },
});
const address = await response.json();
console.log(address);

Response

{
  "chain": "base",
  "address": "0x742d35Cc6634C0532925a3b844Bc9e7595f2bD28",
  "currency": "usdc"
}

Send USDC

Send USDC to the returned address on the Base network. You can send from any wallet, exchange, or bridge that supports Base.

Copy the deposit address

Copy the address from the API response or the project dashboard.

Send USDC on Base

From your wallet or exchange, send USDC to the address. Make sure you select the Base network.

Wait for confirmation

Deposits are confirmed via Bridge.xyz webhook, usually within a few minutes. Your project balance updates automatically.

Only send USDC on the Base network to this address. Sending other tokens or using the wrong network may result in lost funds.

Method 2: Virtual Bank Account (Fiat On-Ramp)

If you prefer to fund with USD, you can create a virtual bank account that automatically converts incoming deposits to USDC.

Create a virtual bank account

From the project dashboard, navigate to Funding and create a virtual bank account. Bridge.xyz provisions a US bank account linked to your project.

Send USD via ACH or wire

Send USD to the virtual bank account from your bank. Both ACH transfers and wire transfers are supported.

Auto-conversion to USDC

Bridge.xyz automatically converts the incoming USD to USDC and credits your project wallet on Base chain.

ACH deposits typically take 1-3 business days to settle. Wire transfers are usually same-day. Your project balance updates once Bridge.xyz confirms the conversion.

Checking Your Balance

After funding, verify your balance:

curl https://api.unwall.xyz/v1/balance \
  -H "Authorization: Bearer aw_live_xxxxxxxxxxxx"

import requests

headers = {"Authorization": "Bearer aw_live_xxxxxxxxxxxx"}
response = requests.get("https://api.unwall.xyz/v1/balance", headers=headers)
print(response.json())

const response = await fetch("https://api.unwall.xyz/v1/balance", {
  headers: { Authorization: "Bearer aw_live_xxxxxxxxxxxx" },
});
const balance = await response.json();
console.log(balance);

Response

{
  "project_id": "proj_abc123",
  "currency": "usdc",
  "available": 5000000,
  "pending": 0,
  "total_funded": 5000000,
  "total_spent": 0,
  "wallet_address": "0x742d35Cc6634C0532925a3b844Bc9e7595f2bD28"
}

All amounts are in micro-USDC (1 USDC = 1,000,000). So 5000000 = 5.00 USDC.
