Accept crypto payments on Arbitrum

Accept USDC and USDT on Arbitrum, settled non-custodially to your wallet, with no platform fee and no KYC to start.

Create an invoice, set Arbitrum as your settlement chain, and send the buyer to a hosted checkout. The moment USDC and USDT lands you get a signed webhook. Funds settle straight to your own wallet; Shieldz is non-custodial and only watches the chain.
