USDC PAYMENTS
Accept USDC. Your server, your wallets.
Add stablecoin payments to your store with self-hosted invoices, branded checkout and a merchant API.
Offer the networks your customers use
Enable verified USDC on Ethereum, Base or Solana. Other supported choices include Arbitrum, Optimism, Polygon and Avalanche, subject to the exact asset’s readiness in your store.
Native USDC and bridged lookalikes are not interchangeable. Compare the contract or mint with Circle’s USDC address list. Customers must send the selected token on the selected network.
From installation to your first USDC invoice
- Install Wholly Crypto, activate billing and create a project and store.
- Back up the project wallet for each network you plan to accept.
- In Store → Payment methods, select the network, find USDC and check its contract before enabling it.
- Choose your invoice defaults and create a small test invoice. Confirm that receipt, status updates and your integration all work.
Checkout shows only ready methods from the chosen store. The same ticker on a different network is a separate payment method.
Clear quotes, visible payment status
Set prices in USD, EUR or another available fiat currency. The checkout calculates the USDC amount using your configured rate spread and upward rounding. Customers see expiry, any amount still due and confirmation progress.
USDC is designed to track the US dollar, but conversion rates can move. Wholly Crypto does not redeem tokens or automatically deposit fiat into your bank account.
Separate processing credits and gas
At the default 1% rate, a $100 invoice uses $1 of prepaid credit. The fee is based on the invoice’s original fiat value, not taken from your customer’s on-chain transfer. Your assigned rate, network fees and server costs apply separately.
Moving USDC requires native network fees: for example, ETH on Base or Ethereum, and SOL on Solana. Keep gas available for sends and sweeps. Read the low-credit rules before enabling automation.
Make it part of your checkout
Use a payment link or create invoices through the API. Verify invoice status and signed notifications before delivering an order. Compare USDT and Bitcoin payment options.
