FAQ

How Shieldz works, how it stays free, and what happens to your money. Short version: payments go straight from your buyer's wallet to yours, we watch the chain and tell you it landed; we never hold it.

How does Shieldz work, is it really non-custodial?

Yes. Payments go buyer's wallet → your wallet, directly. You give Shieldz a receive address (or an extended public key); Shieldz derives payment addresses that belong to you, watches the chain for incoming funds, and notifies you. Shieldz never holds, controls, or can redirect your money, there's no balance to skim, delay, or freeze. With a single address, every invoice settles to the exact address you set, which is shown on the checkout so you and your buyer can verify it.

Is Shieldz safe? Can it drain my wallet?

No. Shieldz never asks you to connect a wallet or approve a token allowance, buyers simply send crypto to a one-time address (or scan a QR), exactly like a normal transfer. There's no smart contract to approve and no spending allowance to grant, so the mechanism wallet-drainers rely on isn't there. Shieldz is non-custodial: it never holds your money and cannot move or freeze it. (Signing in to the dashboard with a wallet is just a message signature that proves you own the address, it moves no funds.)

If it's 0% fees, how does Shieldz make money?

We never take a cut of your payments, you keep 100%. Free accounts show one brief sponsored card on the checkout's “payment confirmed” screen while funds settle; that covers our server and node costs. Prefer a clean, unbranded checkout? Pro is $99/year and turns ads off. Either way you only pay the network's gas fee.

Can Shieldz swap or change my payout address?

No. Funds settle to the wallet you control; Shieldz only watches the chain and notifies you. The receiving address is derived from the key or address you provide and is displayed on the checkout, so a swapped address would be visible.

Do I need to KYC? Do you log my data?

No KYC to start, you're responsible for your own compliance. Shieldz is privacy-first: buyers don't need an account, and shielded Zcash is supported for fully private receipts.

What can my buyers pay with?

USDC and USDT on Base, Arbitrum, Optimism, Polygon, and Ethereum, plus native Bitcoin and shielded Zcash, settled directly to your wallet. Optionally, a buyer can also pay in many other coins; that payment is converted by independent, non-custodial swap protocols and the token you chose still lands in your own wallet.

Is the 'pay any coin' (swap) option also non-custodial?

Shieldz never takes custody either way, but the two paths have a different trust surface, worth being precise about. When the buyer pays the same token you receive, it goes wallet to wallet directly: only the two wallets are involved. When they pay a different coin, the conversion is performed by independent, non-custodial swap protocols (NEAR, Chainflip, Relay) and the settled token is delivered straight to your own wallet. So the swap path is not a simple two-wallet transfer; it relies on those third-party protocols for the conversion leg. Shieldz itself holds no balance and no keys at any step, and takes no fee on the swap. If you want the purest wallet-to-wallet model, accept the same coin you settle in.

What about chargebacks and frozen accounts?

Neither exists here. A confirmed crypto payment is final, and because no account holds your funds, there is nothing to freeze.
