USD CoinUSDCAll of them — every network pays into one USDC merchant balance, so there is nothing to reconcile. Your customer picks the network at checkout; this is what each one costs and how fast it confirms.
| Network | Confirmation time | Typical network fee | Best for | |
|---|---|---|---|---|
| USDC ERC-20 Ethereum |
≈ 15–60 seconds | $0.50–$5, gas-dependent | B2B invoices, treasury payments and customers who hold USDC with regulated exchanges, custodians or in DeFi. The most widely supported USDC standard. | Details |
| USDC SPL Solana |
< 1 second | < $0.01 | Consumer apps, gaming, creator payouts and any checkout with many small payments — the network where USDC is the default dollar. | Details |
| USDC Polygon PoS Polygon |
≈ 2–5 seconds | < $0.01 | E-commerce and SaaS checkouts that want Ethereum-compatible USDC at a fraction of the cost, and customers paying from Polygon-native apps and wallets. | Details |
| USDC Arbitrum One Arbitrum |
≈ 1–2 seconds | < $0.05 | DeFi-native customers and trading platforms that keep USDC on Ethereum's largest layer 2, and merchants who want Ethereum security at layer-2 fees. | Details |
Redirect the customer to a checkout page built in the invoice constructor, styled to your brand. No code beyond a link.
Issue an invoice from the dashboard or the API and send the link by email or chat. Ideal for B2B, services and manual sales.
Create payments programmatically with the API and webhooks, or install the WooCommerce, Shopify or PrestaShop plugin and switch the coin on.
Deposits on every network land in a single USDC balance. From there you decide: hold it, convert other coins into it automatically, or settle to USD or EUR. Withdrawals go out on any network without internal cross-chain fees.
One balance across all supported chains; withdraw on whichever network is cheapest today.
Convert BTC, ETH and other deposits into USDC automatically to remove volatility.
Turn on USD or EUR payouts to your bank account whenever you need fiat.
Our USDC payment gateway handles the entire transaction lifecycle. It generates a unique deposit address per order, monitors the chosen network for incoming funds, and notifies your backend via webhook the moment payment lands. USDC stays at $1, so there is no exchange rate calculation on your end.
Get StartedYour checkout page presents USDC as a payment option. The customer picks their preferred network from Ethereum, Solana, Polygon, or Arbitrum and sees the exact dollar amount to send.
Our API issues a dedicated deposit address on the chosen network, tied to the order amount, your merchant account, and a payment expiry window.
The customer sends USDC from any wallet to the generated address. We monitor all supported networks simultaneously and track the payment in real time.
As soon as the USDC transfer confirms on-chain, we send a signed webhook to your callback URL. Funds are credited to your merchant account right away.

GatewayCrypto / USDC
USDC is pegged 1:1 to the US dollar and backed by fully reserved assets. You invoice in dollars, customers pay in dollars, and your revenue stays predictable.
Process USDC on Ethereum, Solana, Polygon, or Arbitrum. Customers pick the network with the lowest fees, and you get the same dollar amount regardless.
USDC is issued by Circle, a regulated financial institution. Reserves are independently audited, making USDC a trusted choice for B2B and cross-border payments.
Polygon and Arbitrum settle in seconds for a few cents. Solana (SPL) lands in under a second. Even Ethereum ERC-20 confirms in under a minute. You get cleared funds faster than any bank wire.
USDC transfers cross borders without currency conversion fees or correspondent bank delays. Ideal for SaaS platforms, marketplaces, and businesses with international customers.
