Accept USDT on Polygon

Take USDT payments settled on Polygon, wallet-to-wallet, with $0 platform fee and no KYC to start.

Polygon is a low-cost proof-of-stake sidechain, often the cheapest of the five chains and popular with buyers in emerging markets and gaming.

Create an invoice with Polygon as the settlement chain, send the buyer to the hosted checkout, and get a signed webhook the moment the USDT payment confirms. Shieldz is non-custodial: it only ever holds a public key, funds go straight to your wallet.
