The most important setting on the account. Get it wrong and payments go somewhere you don’t control, permanently.
Setting it writes an on-chain attestation from your own wallet. Nobody else can make or change it — not us, not an attacker with our database. It becomes the root of the verification your customers’ browsers run.
Enter the address
Check it character by character. Consider a multisig or treasury wallet rather than a hot wallet.
Never use an exchange deposit address. Exchanges rotate and retire them without warning, and a payment to a dead deposit address is unrecoverable. Use a wallet you hold keys to.
Changing it later means deploying a new pool at a new address. Plan it.
EUR or USD. What prices are quoted in. Purely presentational — settlement is in your chosen token.
Settlement token
USDC, USDT, or EURC. What you’re actually paid in.
In Tokens you enable each (token, chain) pair individually, so you can take USDC on Base without taking USDT on Base. Enforced server-side, not just hidden in the UI.
A cap on how much settlement cost you’ll accept, as a percentage of order value. It becomes a live per-chain minimum.The panel shows the implied minimum per chain as you move it — set 2% and you’ll see the deposit rail disappear on expensive chains below a certain order size. Customers there are offered the connect rail instead. Limits.
Endpoint URL, signing secret, and a delivery log with response codes and bodies.
Set a signing secret before going live. Without one, signatures deliver as the literal string none and you have no way to tell a genuine delivery from a forged one.
There’s a Send test event button — the quickest way to check your verification without making a payment.
How deep a payment must be confirmed before you’re told it’s final. Defaults scale with value and account for each chain’s reorg behaviour.Raise them if you sell anything instantly consumable, where a reversal can’t be recovered by withholding shipment. It costs conversion, so it’s a genuine trade-off. Finality.
If a partner referred you, their code is bound here. It’s set once on account creation and can’t be changed afterwards except by platform support.A referral costs you nothing extra — it comes out of the same 1% you already pay. Fees.
