How to accept Solana payments on your website using Finassets payment gateway

What is a Solana payment gateway? A Solana payment gateway is a crypto payment solution that allows businesses to accept payments over the Solana network. It connects a website or online checkout with payment infrastructure that can process, track, and confirm Solana transactions.

A Solana payment gateway allows businesses to accept cryptocurrency payments through the Solana blockchain. With Finassets payment gateway, you can create a payment project, select a supported cryptocurrency and the Solana network, configure your payment settings, and add a payment button to your website.

For example, a business can accept USDC on Solana and let customers complete payments from a compatible crypto wallet.

This guide explains how to accept Solana payments, how payments on the Solana network work, how to add them to your website, and what businesses should consider before getting started.

What is Solana and why use it for payments?

Solana is a blockchain network that can be used to transfer SOL and supported tokens between blockchain addresses. SOL is the native cryptocurrency of the Solana network and is also used to pay network transaction fees.

For businesses, Solana provides another payment rail for accepting digital currencies online. It can also support stablecoin payments and other tokens issued on the network.

Businesses may consider Solana payments because they:

• Support low network fees: Solana transactions require a base network fee, with an optional prioritization fee.
• Support stablecoin payments: Businesses can use the network for stablecoin payment flows as well as SOL transfers.
• Work for online payments: Solana can be integrated into eCommerce stores, digital services, and other online platforms.
• Provide on-chain transaction records: Transactions can be identified and verified using their transaction signature.
• Enable global payments: Customers can transfer funds using a compatible wallet without relying on a traditional card payment rail.

A payment gateway makes this process easier for merchants by connecting blockchain payments with their existing website and payment flow.

How to accept USDC on Solana

One way to accept USDC (Solana) payments through Finassets is to configure USDC on the Solana network and add a payment button to your website.

Video tutorial: How to accept USDC (Solana) payments on your website

Step 1: Open your Finassets business account

Open your Finassets business account and go to the main dashboard.

The dashboard provides access to the payment tools you need to configure your cryptocurrency payment project.

Step 2: Select “Payment Button”

Open the “Payment Button” section from the Finassets dashboard.

This section allows you to create a payment project and generate a payment button that can be embedded into your website.

Step 3: Click “Add Project”

Click “Add Project” to start configuring your payment project.

Enter:

• Your project name
• Your company name

These details help you identify the project connected to your website.

Step 4: Configure USDC payments on Solana

Complete the project form and configure how the payment option should work.

Select the following settings:

• Select USDC as the cryptocurrency payment option.
• Choose the Solana blockchain network for USDC payments.
• Choose the currency for settlement.
• Decide who pays the transaction fees: Merchant or Customer.
• Set the invoice payment time period.
• Set the rate update interval.
• Add the website URL where the payment button will be used.

Review the settings before continuing. These options determine how the payment project will operate on your website.

Step 5: Create the payment project

Once the configuration is complete, click “Add.”

Finassets will create the project using your selected payment settings.

Step 6: Copy the payment button embed code

After creating the project, copy the generated payment button embed code.

The code connects your website with the configured Finassets payment option. This means you do not need to build the complete blockchain payment infrastructure yourself.

Step 7: Add the payment button to your website

Paste the generated code into the relevant location on your website.

For example, you can place the payment button on a payment page or another part of your checkout flow where customers choose how they want to pay.

Customers can then select USDC on Solana and complete their crypto payment.

Your website is now configured to accept USDC on Solana through the Finassets crypto payment gateway.

How do Solana payments work?

At the blockchain level, a Solana payment transfers SOL or a supported token from a sender to a recipient on the Solana network.

For an online merchant, the payment flow can be simplified through a Solana payment gateway.

A typical flow looks like this:

1. The customer chooses a supported cryptocurrency at checkout.
2. The payment system creates the payment request.
3. The customer sends the payment using a compatible crypto wallet.
4. The transaction is submitted to the Solana network.
5. The network processes the transaction.
6. The transaction can be verified on-chain.
7. The payment status is updated as the payment is processed.

Solana transactions contain signatures and transaction data. A transaction signature can serve as a unique identifier for finding and verifying the transaction on the blockchain.

This on-chain record can also help merchants with payment verification, transaction monitoring, payment tracking, and reconciliation.

What fees apply to Solana payments?

Businesses should distinguish between payment processing fees and Solana network fees.

Every Solana transaction requires a network fee paid in SOL. The standard fee structure includes a base fee, while a prioritization fee can also be added.

When setting up the Finassets payment project described above, the merchant can choose whether the Merchant or Customer pays the transaction fees.

This gives businesses more control over how transaction costs are handled in the customer payment experience.

The total cost of accepting payments can therefore depend on the payment provider's processing fee, the blockchain network fee, and the particular payment configuration.

Solana stablecoin payments: USDC and USDT

Stablecoins such as USDT and USDC can be useful for businesses that want blockchain-based payments without receiving a cryptocurrency whose market value can change significantly against fiat currencies.

With USDC payments on Solana, a customer transfers a USD-denominated stablecoin over the Solana network instead of sending SOL.

This separates two concepts:

Payment asset: the cryptocurrency or stablecoin being transferred, such as USDC.

Payment network: the blockchain used to process the transfer, such as Solana.

This distinction is important when configuring a payment gateway. Selecting USDC alone does not define the blockchain network. The merchant also needs to select the supported network used for that payment.

For the Finassets setup covered in this guide, that means selecting USDC as the cryptocurrency and Solana as the blockchain network.

What is a Solana payment gateway API?

A Solana payment API provides a programmatic way for a website, application, or backend system to interact with crypto payment infrastructure.

An API integration can be useful when a business needs a more customized payment flow than a ready-made payment button.

Depending on the payment infrastructure, API-based implementations can involve:

• API authentication and credentials
• Payment requests
• Payment status monitoring
• Transaction details
• Payment verification
• Webhook notifications
• Callback URLs
• Payment references and order IDs
• Backend integration

Developers building directly on Solana can also interact with the network through RPC infrastructure. Solana's own payment documentation lists direct RPC as an option for custom payment flows, but describes it as more complex than ready-made payment components.

For many merchants, using existing payment infrastructure can therefore reduce the development work required to launch Solana payments.

Who can benefit from accepting Solana payments?

A SOL payment gateway or Solana stablecoin payment solution can be relevant to businesses whose customers already use cryptocurrency.

Potential use cases include:

• eCommerce stores that want to add crypto to their checkout.
• Digital service providers serving international customers.
• Online platforms that want additional payment methods.
• Web3 businesses whose users already interact with blockchain wallets.
• Global businesses receiving payments across different markets.
• Merchants accepting stablecoins such as USDC over the Solana network.

The right payment methods ultimately depend on your customers. Solana payments can complement cards, bank transfers, other cryptocurrencies, and traditional payment methods rather than replacing every existing option.

What should you consider before accepting Solana payments?

Before implementing a Solana payment solution, businesses should consider the complete payment flow rather than only the blockchain transaction.

Important areas include:

• Supported assets: Determine whether you want to accept SOL, stablecoins, or other supported tokens.
• Network selection: Make sure customers send funds using the correct blockchain network.
• Fees: Consider both payment processing and blockchain network fees.
• Settlement: Decide which settlement currency fits your business.
• Payment verification: Ensure transactions and payment statuses can be correctly matched to customer orders.
• Security: Protect business accounts, API credentials, wallet-related information, and other sensitive access data.
• Reconciliation: Maintain clear transaction history and payment records.
• Customer experience: Make the network, payment amount, and payment instructions clear at checkout.
• Compliance: Applicable KYB, KYC, AML, sanctions, accounting, and other requirements can vary by business and jurisdiction.

Businesses should obtain appropriate legal, tax, or accounting advice where local requirements are unclear.

Solana payment button vs. API integration

Businesses generally have two broad approaches when adding Solana payments to a website.

A payment button is suitable when you want a simpler implementation. You configure the payment project, generate the embed code, and add it to the relevant page on your website.

An API integration gives developers more control over the payment experience and backend processes. It can be more appropriate when payment creation, status updates, order management, or other processes need to interact directly with existing business systems.

The best integration method depends on your website, development resources, transaction volume, and required payment flow.

These features make Finassets a solid Solana payment gateway for businesses that want to accept payments over the Solana network while maintaining access to payment management, settlement, security, and integration tools.

Finassets Payment Processing Fees & Supported Cryptocurrencies

What are the fees for accepting Solana payments?

Finassets charges payment processing fees based on payment volume. Businesses should also account for Solana network fees when calculating the total transaction cost.

Solana network fees are separate from the Finassets processing fee. Solana network fees are typically below $0.01 per transaction. The exact network cost depends on the Solana transaction itself and applicable network conditions.

Businesses processing large transaction volumes can evaluate the applicable Finassets fee tier alongside Solana network costs when comparing crypto payments with other payment methods.

Which cryptocurrencies does Finassets support?

Finassets supports 70+ cryptocurrencies, allowing businesses to provide multiple cryptocurrency payment options rather than relying only on Solana.

Supported digital assets include:

• Bitcoin (BTC)
• Ethereum (ETH)
• Tether (USDT)
• USD Coin (USDC)
• Solana (SOL)
• Tron (TRX)

Stablecoin support also covers major blockchain networks, including:

• Ethereum (ERC-20)
• Tron (TRC-20)
• BNB Smart Chain (BEP-20)
• Solana

This multi-cryptocurrency support allows businesses to accept crypto payments according to customer preferences. A merchant can offer Solana payments alongside Bitcoin, Ethereum, stablecoins, and other supported digital currencies rather than relying on a single crypto payment option.
