Crypto (your own wallet, non-custodial)

How it works

You enter your wallet's extended public key (xpub) once. For every payment a new address is derived from it; the customer pays that address and the money lands directly in your wallet. The panel watches the chain and credits the balance once the required confirmations are in.

• Your private key is never on a server; an xpub can derive addresses but cannot spend.
• There is no intermediary: nobody holds your balance or takes a cut. Only the network fee is paid.
• Using the same xpub on two panels does not collide: the derivation counter belongs to the wallet.

Supported networks and assets

Network	Assets	Confirmations
TRON (TRC-20)	USDT	19 blocks
BNB Smart Chain (BEP-20)	USDT, USDC	15 blocks
Polygon PoS	USDT, USDC	40 blocks

There are two xpub fields: xpub_tron (TRON addresses) and xpub_evm (BSC and Polygon share one EVM key). You may enter only one; a network without a key is not offered to customers.

Where to get the xpub

From your hardware or software wallet's "export account / extended public key" screen. The derivation path is shown per network in the add-method dialog; make sure your wallet uses the same path, or the addresses the panel derives will not appear in your wallet.

Check: after adding the method, the dialog shows the first derived address; if your wallet's "receive addresses" list shows the same address, the setup is right.

Amount rules

• A quote is valid for a limited time; once it expires the customer gets a new one.
• Overpayments are credited in full.
• A shortfall within 1% of the quote is accepted in full (the network-fee gap is on you); larger shortfalls leave the payment "pending" and the customer can send the remainder to the same address.
• A txid is processed only once.
