Accept USDT payments

Accept USDT (Tether) across five EVM chains, non-custodially, with no per-transaction fee.

Same model as USDC: choose a chain, get a derived receive address, and reconcile via signed webhooks or polling. You only ever pay network gas.

How it works

Create an invoice, send your customer to the hosted checkout, and get a signed webhook the moment the USDT payment lands, funds settle straight to your wallet. Shieldz is non-custodial: it only ever holds a public key.

curl https://shieldz.cash/api/v1/invoices \
  -H "Authorization: Bearer sk_live_…" \
  -d '{ "amount_usd_cents": 5000, "memo": "Order #1234" }'

Buyers can pay with USDT or other supported coins. See supported coins, the API docs, and official SDKs.
