NueSafe Merchant portal
Payment gateway

Accept Bitcoin. Settle in seconds.

NueSafe is a Lightning Network and multi-currency payment gateway for businesses. Create invoices, take deposits, and send payouts over Bitcoin Lightning, on-chain rails, and major networks — then hear about every payment over webhooks or email.

The networks merchants actually use.

One API and one hosted checkout. Amounts can be shown in USD while settlement happens in the underlying asset.

Bitcoin

Lightning

Instant invoices over the Lightning Network. Customers pay from wallets such as Cash App, Strike, or any BOLT11-compatible app. Confirmation is typically seconds, not blocks.

Bitcoin

On-chain BTC

Unique receive addresses per deposit, confirmation tracking, and treasury sweep into a hot wallet. Same merchant balance as Lightning.

Networks

ETH, SOL, LTC

On-chain deposits and redemptions on Ethereum, Solana, and Litecoin. Addresses are HD-derived so each payment has its own destination.

Stablecoins

USDC, USDT, PYUSD

Dollar-denominated tokens on Ethereum and Solana, tracked per asset and per chain so balances never get mixed across networks.

Checkout

Hosted payment page

A branded checkout you can open as a page or embed. Collect customer details, show a QR or address, and wait for the confirmed payment.

Notify

Webhooks and receipts

HTTP callbacks when a payment completes, expires, or is paid out. Merchants can also opt in to transactional email receipts for the same events.

Technology

How a payment moves.

1

Create

Your backend calls the NueSafe API, or a customer opens a hosted checkout link. We return a Lightning invoice or a chain-specific receive address.

2

Detect

Our node and chain watchers see the payment. Lightning settles as soon as the invoice is paid. On-chain deposits wait for the required confirmations.

3

Credit

The merchant balance updates, a webhook fires, and — if they turned it on — a receipt goes to the inbox on their account. Payouts reverse the path.

For engineers

REST, API keys, and signed webhooks.

Integrate from your server. Never put a live key in a browser. Documentation lives at docs.nuesafe.com.

Company

A live payment platform, not a landing page.

NueSafe has been processing production payments since July 2026. The merchant portal, hosted checkout, API, and documentation are already online. This site is the public description of that stack.
