What is cross chain in crypto?

Cross-chain payments let customers pay on one blockchain while the merchant settles on another. It removes chain lock‑in, so each side can use the blockchain network it prefers.

In the context of processing crypto payments, cross chain meaning is connecting assets and networks behind the scenes. A gateway receives the customer’s coin on the chosen chain, converts as needed, then delivers funds in the merchant’s target asset or fiat. This keeps checkout simple for buyers and streamlines settlement for finance teams.

How it works

1. Create an invoice. The merchant sets the amount and supported networks in the dashboard or through API. See Accept crypto.
2. Customer selects the coin and chain. Examples: Bitcoin, Ethereum, Solana, Tron, XRP, Bitcoin Cash, Dogecoin, or Cardano.
3. Payment. The gateway displays a network‑specific QR wallet address and tracks on‑chain status of the payment in real time.
4. Settlement. After a set amount of network confirmations, the gateway acknowledges the payment and credits the merchant’s wallet on the chosen network.
5. Operations. Merchant views reports, tracks transactions, and manages users in the back office as needed.

Benefits of cross‑chain payments

• Customer choice at checkout. Let buyers pay on the chain they already use. This cuts drop‑off and reduces support tickets about network mismatches.
• Lower network costs. Route payments over cost‑effective chains like Tron or Solana when speed and fees matter at scale.
• Faster settlement. Confirm in seconds or minutes, then receive funds in the asset that fits your treasury plan.
• Smoother finance ops. Auto‑conversion, clear records, and exportable reports simplify accounting.
• Automation. Use one API, hosted invoices, and e‑commerce plugins to cover many networks, including automating crypto-to-fiat transaction flows.

Cross‑chain vs cross‑border

Cross‑chain means a payment starts on one blockchain and settles on another. Cross‑border means a payment moves between countries or jurisdictions.

You can have one without the other, or both at the same time.

• Cross‑chain payment: Routes value across different networks. Someone buys in SOL, you settle in BTC.
• Cross‑border payment: Moves value between jurisdictions or fiat currencies. Someone in Canada pays a German vendor.
• Both together: A buyer in Mexico pays in TRX on Tron, the merchant settles to EUR and withdraws to a EU bank account.

Practical examples of cross-chain payments

• E‑commerce checkout. A customer pays in SOL on Solana. The merchant settles to USDC on the Tron network near-instantly.
• Travel booking. A buyer uses TRX on Tron to book a hot deal quickly. Funds auto‑convert to BTC and get sent to a treasury wallet.
• SaaS payouts. The company collects from customers in ETH on Ethereum, then pays affiliates in XRP using Send crypto for a cost-effective mass payout.
• Marketplace refunds. The seller receives in USDC, the buyer prefers BCH. Conversions are made automatically at checkout.
