Supported Chains

How Chain Selection Works

1. Merchant creates a charge - No chain is specified at this point

2. Customer opens payment link - They see a list of available chains

3. Customer selects a chain - The clone contract is deployed on that chain

4. Customer sends USDC - Payment is sent to the clone address

5. Automatic settlement - Funds are forwarded to the merchant
