How to accept USDC (Polygon)
Create a USDC deposit address
Send one request with the URL to notify and the EVM wallet that receives the money. The same callback URL always returns the same address.

USDC on Polygon
Polygon PoS has negligible gas costs and a fast block time; payments wait 64 blocks before forwarding to stay safe from reorganisations.
For a USDC token payment, we send the gas the transfer needs ourselves and charge its cost in USDC at the market price. Your wallet never needs native coin.
Prefer to see the numbers first? Try the simulator, or read how fees and callbacks work.
USDC (Polygon) payments: questions
What is the minimum USDC (Polygon) payment?
0.5 USDC. A smaller payment is still recorded and shown in /logs/, but it is not forwarded, so that the network cost can never eat the payment.
How long until a USDC (Polygon) payment reaches my wallet?
We forward it once it has 64 confirmations on Polygon, which takes about 2 minutes on average, then send your server a signed callback with the forwarding transaction id.
Who pays the network fee for USDC (Polygon)?
We send the gas the token transfer needs and recover its cost in USDC at the market price, together with our 1.25% fee. You never need native coin in your wallet.
Do I need an account to accept USDC (Polygon)?
No. There is no sign-up and no API key: one request to /polygon/usdc/create/ with your callback URL and your EVM wallet returns a deposit address. Funds go straight to that wallet.
