NadiFin Crypto Payment Gateway for WooCommerce

Yes, accepting cryptocurrency as a medium of exchange is completely legal in the vast majority of global jurisdictions. Our infrastructure simply facilitates the technical transfer of digital assets.

No. We utilize a strict non-custodial settlement model. As soon as the transaction is processed, your funds are pushed directly to your own secure wallet on the blockchain. We do not hold your money, so it cannot be frozen by us or any traditional bank.

No. NadiFin operates with a strict No KYC policy for merchants, and your customers are never required to upload identity documents to pay in cryptocurrency.

NadiFin supports top global cryptocurrencies, allowing your customers to pay effortlessly in Bitcoin (BTC), Ethereum (ETH), Solana (SOL), Litecoin (LTC), Monero (XMR), USDT, USDC, BNB, Ripple (XRP), Dogecoin (DOGE), Cardano (ADA), and Tron (TRX).

We use a cost-saving architecture designed to protect merchants from massive network fees and crypto market volatility. While your customers have the freedom to pay in their preferred coin, NadiFin automatically sweeps the funds, manages network gas, and settles your earnings directly into your secure USDC wallet (Polygon network).

When a customer checks out, NadiFin instantly calculates the live exchange rate based on your fiat pricing (USD, EUR, GBP) and generates a unique mathematical child-wallet deposit address. Once the customer sends the crypto, our background nodes detect the payment, sweep the funds, and fire a webhook to automatically mark the order as paid in your store.

NadiFin charges only a 1% fee per transaction. To convert the customer’s native cryptocurrency (e.g., Bitcoin, Litecoin) into USDC on the Polygon network, the transaction passes through an automated cross-chain liquidity bridge. This may incur a small dynamic swap fee (typically ~0.5%) charged by the protocol, which is seamlessly factored into your final net payout.

Settlement is fully automated. As soon as a customer’s payment hits the required network confirmations, NadiFin bridges the funds directly to your designated USDC wallet. You maintain absolute self-custody, while most payouts arrive within an hour.

Please understand, a payout may take up to 24 hours in rare instances. This is an automated safeguard specifically built to protect your profits. If gas fees on the customer’s chosen blockchain experience an extreme, temporary spike, our system pauses the sweep until network congestion clears.

Our system monitors the blockchain in real-time. If a customer sends less than the required amount, the transaction status will reflect the partial payment and our dynamic checkout will prompt the customer to fulfill the remaining balance before the system registers it as a completed order.

Because cryptocurrency payments are final and irreversible on the blockchain, there are no forced chargebacks. Any refunds you wish to grant must be handled manually between you and your customer, keeping you in complete control of your business capital.

NadiFin is truly global. Merchants from almost anywhere in the world can integrate our gateway to receive USDC, and your customers can pay you globally, subject only to standard international compliance.
