Accept USDC on Base

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

Base is an Ethereum layer-2, so gas is typically a few cents and confirmations are fast, a solid default for everyday invoices.

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

curl https://shieldz.cash/api/v1/invoices \
  -H "Authorization: Bearer sk_live_…" \
  -d '{ "amount_usd_cents": 5000, "settlement": { "chain": "BASE", "asset": "USDC" } }'
