Included

Everything around the form, set up for you.

  • USDC straight to your wallet

    Guests pay from MetaMask or another wallet straight into yours. No payment company sits in between, and you don't need a business bank account for it.

  • Five networks

    USDC on Base, Ethereum, Polygon, Arbitrum and Optimism. Base comes first, with network fees that are usually a few cents.

  • Confirmed wallets

    Guests connect their wallet and sign a free message, so you know each wallet is really theirs. Signing moves no funds.

  • Holders only

    Let only holders of your NFT or token register. Wallets are checked when they're confirmed and again when the form is sent.

  • Checked on the blockchain

    A registration is marked paid once its payment is confirmed on the blockchain, and each transaction counts only once.

  • One per wallet

    One registration per wallet, email or mobile number, so allowlists and limited spots stay fair.

  • Cards too

    Offer card payments through your Stripe account on the same page, for guests without crypto.

  • QR tickets and reminders

    Tickets with QR codes for the door, and reminders with a payment link for anyone who registered but didn't pay.

Questions

Do my guests need a crypto wallet?

To pay in USDC or confirm a wallet, yes: MetaMask, Coinbase Wallet, Rabby or another wallet in their browser, or their wallet app's own browser on a phone. You can also take cards from guests who prefer them.

Does Xenpai hold the money?

No. The guest's wallet sends USDC straight to yours. Xenpai only reads the blockchain to confirm the payment arrived.

Which tokens and networks can people pay with?

USDC on Base, Ethereum, Polygon, Arbitrum and Optimism.

How does holders-only registration work?

Give the NFT or token's contract address and network. After a guest confirms their wallet, Xenpai checks it holds at least one, or the amount you set.

How do refunds work?

You send the USDC back from your wallet. Xenpai shows how much to send and to which address, and marks the payment refunded.
