Stablecoin Payment Fees Explained: Network Fees, Platform Fees, and FX Savings

If you’re part of a team that routinely pays vendors, contractors, or business partners located overseas, then you probably know how much money disappears into fees before a transfer settles. Correspondent bank charges and FX spreads were just the costs of doing business. That was true, and then crypto came along.

Between October 2024 and October 2025, $9 trillion in stablecoins were moved globally, up 87% year over year, according to 2025’s State of Crypto Report from a16z. Unlike a cryptocurrency like Bitcoin, stablecoins aren’t speculative investments, so those figures don’t come from trading activity. That $9 trillion is largely real businesses moving real money; however, if you’re considering using stablecoins for your business’s outbound payments, there are some things to know about before diving in.

The total cost of a stablecoin transfer includes on-chain gas fees, platform or processor fees, FX conversion at the off-ramp, and more. While these fees are often significantly lower than a traditional bank transfer, it’s still important to know what they are, where they come from, and the best practices for minimizing fees.

This article breaks down the full fee structure behind stablecoin payments, along with some introductory information about how the blockchain really works. And if you’re a business owner looking to add crypto capabilities to your financial stack, consider Slash, a business banking platform that natively supports sending and receiving USDC and USDT stablecoins by converting your cash into crypto, a process called on- and off-ramping.¹,⁴ Slash’s built-in crypto on/off ramps connect your accounts to the blockchain without the complexity of managing a separate exchange platform or your own wallet, giving you easy access to the low fees and fast settlement of the blockchain.

Glossary

Here are some key terms about cryptocurrency and the blockchain that will be helpful to know throughout this guide:

Cryptocurrency: A form of digital currency that can be used for both electronic payments and as a store of value. Cryptocurrencies use cryptography to secure transactions and record them on a public ledger.
Fiat currency: Federally-issued money that is declared legal tender, such as the U.S. dollar or the euro. The value of fiat currencies comes from their issuing government and central bank instead of a physical commodity like gold.
Blockchain: A decentralized ledger that records and verifies transactions across a network of computers rather than relying on a centralized authority. Once a transaction is confirmed and added to the blockchain, it becomes very difficult to alter. This structure allows payments to be verified and settled without relying on an intermediary like a correspondent bank.
On/off ramps: Services or tools that allow users to convert cryptocurrency into fiat and vice versa
Crypto wallet: A digital tool that securely stores a user’s cryptographic keys, granting them access to their cryptocurrencies. Despite the name, it doesn’t technically hold coins; the funds live on a blockchain network.
Validator: A specialized participant (or computer node) on a blockchain network that verifies the authenticity of a transfer and records it to the public ledger.
Gas fees: Also known as network fees, these are the small fees networks charge per payment.

What Are Stablecoins?

A stablecoin is a digital token designed to hold a stable value, typically by maintaining a 1:1 peg to a fiat currency like the U.S. dollar. When businesses use stablecoins for payments, they're almost always working with fiat-backed stablecoins like USDC (Circle) and USDT (Tether), which are backed by U.S. dollars and Treasury reserves. Those two tokens alone account for more than 90% of total stablecoin supply.

With crypto, payments settle in the recipient's wallet in seconds. There are no bank cutoffs, batch windows, or correspondent banks to route through, which means minimal friction and little to no processing fees. The main cost is a gas fee, which is a small charge that offsets the computational power required to process the transaction on the blockchain. Gas fees generally range from a few cents to $2, even during peak trading hours.

One important caveat: confirmed crypto transactions are irreversible. There are no chargebacks or recalls, so it's important to verify recipient details before sending. Stablecoin payments also require both parties to have a compatible crypto wallet. As adoption grows, that obstacle will likely start to fade away.

How Stablecoin Payment Fees Work

The main draw of using stablecoins is their relatively low fees, especially for outbound international payments. But, aside from the gas fee, there are some other ways that costs can compound when using crypto depending on the payment provider. The layering of fees into a cryptocurrency transfer is often called the “fee stack,” since it involves charges from a couple different sources.

Consider a business sending $10,000 of USDC to a contractor in France from their Slash account. Here’s where some of the fees would show up for both the payor and payee:

On-ramp fee (USD → USDC): Slash charges a small percentage to convert dollars into USDC, typically under 1%. Slash users are not charged gas fees to access the blockchain.
Off-ramp fee (USDC → EUR): The contractor's wallet or exchange converts USDC to euros on their end, usually another 0.5–1.5%.
FX spread: A small spread may apply to the payee when they convert to euros on the receiving side.

All-in, you're looking at roughly 1–2% of the payment amount to move money from a US bank to a euro bank account. While an international wire is still a practical option for sending large payments (in the thousands of dollars) since they are often priced at a flat fee, the practical upshot is that stablecoins can be incredibly useful for sending small, recurring payments due to their low percentage fee stack.

Network Fees: How Blockchain Gas and Chain Choice Shape Your Costs

Network fees are charges paid to validators, which are the computers that process and record transactions on the blockchain. One thing that often catches people off guard when they try dabbling in crypto: network fees often can’t be paid in the cryptocurrency of your choosing. They're paid in the native token of whatever blockchain you're using. For instance, if you’re using the Solana network, then you'll need a small amount of SOL in a crypto wallet to pay for the fees.

This is a point where newcomers to crypto might find themselves a little overwhelmed. To send stablecoins on-chain, you need a crypto wallet. That means that if you want to send USDC on the Solana chain, you’ll end up needing to monitor two balances instead of one and occasionally topping up your fee token when it runs low. If your SOL balance hits zero, your transaction won't go through, even if your USDC balance is fine. Slash abstracts away this complexity; our crypto infrastructure partner, Bridge, handles gas fees for you whenever you on-ramp into USDC or USDT.

If you opt to manage your own crypto wallet for payments, however, you’ll find that some blockchain networks cost a little more than others. Here’s some of the typical network costs and settlement times among popular blockchains:

Network	Typical Cost Per USDC Transfer	Settlement Time
Ethereum L1	$0.50–$5+ (congestion-dependent)	12–15 seconds
Base (L2)	$0.01–$0.10	2–5 seconds
Arbitrum (L2)	$0.01–$0.15	1–3 seconds
Solana	$0.01–$0.05	Under 1 second
Polygon	$0.01–$0.05	2-5 seconds

Ethereum fees work a bit differently than most other blockchains. Every transaction has a base fee set by the network, plus an optional priority fee if you want faster confirmation. When the network gets congested, both can spike, which can make Ethereum one of the pricier options. It's still the dominant network for stablecoins, though, handling around 65% of USDC volume and 48% of USDT, per FXC Intelligence.

If your business runs regular contractor payroll or vendor payment cycles, batch transactions can be a good cost saver. Sending one aggregated transaction that distributes to 50 recipients in a single on-chain operation costs roughly the same in gas as a single payment, rather than 50 separate transactions. Not all networks support batch processing, however, so do some research beforehand if you intend on trying batches out.

Foreign Exchange Costs in Cross-Border Payments

Even though USDC is pegged 1:1 to the U.S. dollar, recipients getting paid in a different currency will need to convert it at some point. That conversion, the off-ramp, is where FX costs enter the picture.

Take a $2,000 payment from the U.S. to Colombia via USDC on Solana. The sender pays under $0.02 in network fees. When the recipient in Colombia converts into pesos through a local exchange or off-ramp provider, it’ll apply its own spread. Off-ramping from stablecoin to fiat typically costs between 0.5% and 3%, though this varies by corridor and provider.

The regulatory picture also varies by country. Nigeria has introduced a formal framework under its Investment and Securities Act 2025, requiring stablecoin issuers to obtain licenses and meet AML and KYC standards. Brazil has similarly imposed detailed rules through BCB Resolution No. 520/2025, including transaction limits, reporting requirements, and restrictions on algorithmic stablecoins. These frameworks don't prohibit stablecoin payments, but they do add compliance layers that affect which off-ramp providers operate locally and how.

If the recipient is comfortable holding USDC, though, they can skip the conversion entirely. No off-ramp, no FX spread, and no conversion cost to deal with.

Comparing Stablecoin Payments vs. Wires, Cards, and PSPs

Though it may seem like stablecoins are a minefield of fees, their fee stack still comes in a lot lower than traditional bank rails. This can be especially true of international payments or smaller B2B transfers. Here’s a breakdown of several of the most common cross-border payment methods and their typical fees:

	SWIFT Wire	Global ACH	Cards	Stablecoin Rails
Transaction fee	$15–$50 flat	Often free to ~$3 (domestic); varies internationally by provider	2.5–3.5%	Cents–$2 (network) + 0.2–1% (platform)
FX margin	1-3%	1–3% (varies by bank or provider)	1–3% included	0.1–2.5% at off-ramp, depending on region
Settlement time	1–5 business days	1–3 business days	1–3 days to merchant	Seconds to minutes
Reversals	Possible (with effort)	Limited recall options	Chargebacks available	Irreversible on-chain
Best for	Large B2B payments, established relationships	Bulk payroll, vendor batches in supported corridors	Consumer checkout, subscriptions	Fast cross-border B2B payments or high-frequency payouts

Outside of their lower costs for smaller or recurring cross-border payments, it's worth bearing in mind that the blockchain comes with other benefits, too. Stablecoin payments can be sent anytime: at midnight, on weekends, and on federal holidays. They also settle in a matter of minutes, while a wire on the SWIFT network can take anywhere from one to several business days depending on the corridor and correspondent bank relationships involved. For all these reasons, and due to the strengthening platforms supporting access to the blockchain, stablecoins have seen a meteoric rise in popularity for everyday business transfers.

Frequently Asked Questions

What’s the difference between USDC and USDT?

For most use cases, USDC and USDT are nearly identical. However, this isn’t the case when making payments to Europe. USDC is compliant with the European Union’s Markets in Crypto-Assets (MiCA) regulations, which took effect in June 2024, while USDT is not. The MiCA regulation is the EU’s legal framework that enforces uniform rules for crypto-asset issuers and service providers (CASPs) across the EU, and it’s one example of how regulatory bodies set rules for stablecoin issuers in different regions.
