How to pay with USDC
New to crypto? No problem. USDC is a digital dollar — 1 USDC ≈ $1. You can buy it in minutes on an app you may already have, then send it to us on the Solana or Base network. Here's the whole thing, step by step.
1. Buy USDC
On Coinbase, Crypto.com, Robinhood, or Kraken.
2. Pick the network
Solana or Base — match your checkout choice.
3. Send it
Paste the address from your order page & confirm.
What is USDC?
USDC is a stablecoin — a cryptocurrency pegged 1-to-1 to the US dollar and backed by regulated reserves. Its value doesn't swing like Bitcoin. You buy it with a debit card or bank transfer, and one USDC is always about one dollar, so your order total is easy to match.

If you hold USDC in a self-custody wallet, just send it directly — use Phantom for the Solana network or Coinbase Wallet / MetaMask for Base. Skip to step 3.
Choose the right network
Use the same network you selected at checkout — the address on your order page is for that network.
Solana
- Very fast — usually a few seconds
- Fees around a fraction of a cent
- Supported by Coinbase, Crypto.com, Robinhood, Kraken
Base
- An Ethereum layer-2 — low fees

The network must match. A Solana address and a Base address are not interchangeable. Send Solana-USDC to the Solana address, Base-USDC to the Base address — the one shown on your order page.
