International business payments are broken in ways that most business owners have simply accepted as normal. A $500 wire transfer to a supplier in Vietnam costs $30 in fees before it even leaves your bank, takes three to five days to arrive, and may pass through two or three correspondent banks along the way, each potentially taking their own cut. Stablecoins, specifically USDC on Solana, offer a fundamentally different model. This post explains how the current system works, what it actually costs, and how to run a practical cross-border payment workflow using stablecoins instead.
What Stablecoins Are and Why USDC Is the Right One for Business
A stablecoin is a cryptocurrency designed to hold a fixed value, typically pegged 1:1 to the US dollar. Unlike Bitcoin or Ethereum, which fluctuate in price, a stablecoin is meant to always be worth exactly $1.00. This makes it usable as an actual medium of exchange for business transactions rather than a speculative asset.
There are several stablecoins in existence, but for business purposes, USDC (USD Coin) is the standard. It is issued by Circle, a regulated financial company, and is fully backed by cash and short-term US Treasury bonds held in segregated accounts. Circle publishes monthly attestations from a major accounting firm confirming the reserves. USDC is not an algorithmic stablecoin (the kind that collapsed in 2022); it is a straightforward dollar-backed token with transparent reserves.
USDC runs on multiple blockchains, but Solana is the best network for business payments because of its combination of speed (transactions in under a second) and cost (fees of about $0.00025).

How International Wire Transfers Actually Work (And What They Cost)
Most business owners know wires are expensive but do not know exactly why. Here is the actual chain of events when you send an international wire.
Your bank debits your account and sends a SWIFT message to its correspondent bank (often JPMorgan, Citibank, or similar). That bank routes the payment to another correspondent bank in the destination country. That bank routes it to the recipient’s local bank. The recipient’s bank credits the account. Each bank in this chain may charge fees. Your sending bank charges you $25 to $50. Intermediate correspondent banks may deduct $10 to $25 before passing the funds along. The recipient’s bank may charge an incoming wire fee of $10 to $25. Then there is the exchange rate: if you are sending USD to a non-USD country, your bank’s exchange rate is typically 2 to 4 percent worse than the interbank rate. On a $5,000 payment, that spread alone could cost $100 to $200.
Total cost on a $5,000 international wire: easily $80 to $300 in combined fees and FX spread. And the payment may take three to five business days to clear, sometimes longer if a correspondent bank flags it for review. For US businesses, the SBA’s business finance resources cover the regulatory framework around international payments, but none of the traditional tools eliminate the underlying cost structure of the correspondent banking system.
How USDC on Solana Compares
With USDC on Solana, the transaction is peer-to-peer. There is no SWIFT, no correspondent bank, no intermediary. You send USDC from your wallet directly to the recipient’s wallet address. The fee is approximately $0.00025. The payment settles in under one second. The recipient receives exactly what you sent.
If you are paying a supplier $5,000, they receive $5,000 in USDC. No deductions. No delays. They can then convert USDC to their local currency through a local exchange or over-the-counter desk in their country.
The cost difference is not marginal. It is structural. The only remaining cost is the off-ramp: how the recipient converts USDC to local currency. In most countries, they can sell USDC on a local exchange and withdraw to their bank account. The exchange fee and potential FX spread at that point depends on their local market, but it is typically lower than what the traditional correspondent banking system charges.

Practical Workflow for International USDC Payments
Paying an International Supplier
First, confirm your supplier is willing and able to receive USDC. Most suppliers in markets with active crypto adoption (Southeast Asia, Latin America, Eastern Europe, parts of Africa) are familiar with this. Send them a brief explanation of what USDC is and how to set up a Solana wallet if they do not have one. The setup takes about 10 minutes on their end with Phantom.
Once they have a Solana wallet address, add it to your vendor records alongside their bank details. Before processing a large payment, send a $1.00 test transaction, confirm they received it, and then send the full amount. Keep the transaction hash as your payment record. The Solana blockchain provides a permanent public record of every transaction, which you can verify using block explorers like Solscan or Solana Explorer.
Receiving from International Clients
If you provide services to international clients, invoicing in USDC can eliminate the FX complexity for both parties. Your invoice is denominated in USD (since USDC is $1.00), the client pays in USDC from wherever they are, and you receive it in your wallet instantly. No waiting for a wire to clear. No wondering if the bank rejected the payment for compliance reasons.
Include your Solana wallet address (and specify USDC on Solana, not another network) on your invoices alongside your standard bank details. Offer it as an option, not a replacement, until you are confident your clients can handle it.

Compliance Considerations
Stablecoin payments are not a way to avoid compliance obligations. They are a faster, cheaper payment rail, not a legal gray area. For US businesses, USDC payments to foreign vendors are still subject to the same OFAC sanctions screening requirements as wire transfers. You cannot pay a supplier in a sanctioned country (Cuba, Iran, North Korea, etc.) in USDC any more than you can via wire.
The IRS requires you to track all crypto payments for tax purposes. For USDC, because it is pegged to $1.00, the accounting is simple: the dollar amount you sent is the dollar amount of the business expense. Keep records of transaction hashes, dates, amounts, and vendors.
For contractors specifically, the 1099 reporting rules apply regardless of payment method. See the post on paying contractors in USDC on Solana for details on that workflow, including W-9 collection and 1099-NEC filing requirements.
Which Countries Have Friction
USDC payments work most smoothly in countries with active crypto exchanges and clear (or neutral) regulatory posture: most of the EU, the UK, Singapore, Japan, Australia, Mexico, Brazil, Nigeria, Kenya, Philippines, and India. In these markets, your vendors and contractors can receive USDC and off-ramp to local currency without significant difficulty. Local exchanges in these markets typically offer competitive conversion rates relative to the traditional correspondent banking spread.
Countries with more friction include China (crypto largely banned for most purposes), Russia (sanctions and exchange restrictions), and some Gulf states with unclear regulatory status. This does not mean USDC payments are impossible in these markets, but the off-ramp may be harder for the recipient. Check current conditions before setting up a regular payment workflow with suppliers in these regions.
Getting Started
The practical first step is a conversation with your highest-cost international payment relationship, whether that is a supplier, contractor, or service provider. Walk them through the USDC setup. Send a test payment. If it works, you have just discovered a payment channel that costs less than a dollar to use no matter how large the transaction. That efficiency compounds over time.
The wire transfer system was built for a world without programmable money. USDC on Solana is what happens when you remove the intermediaries entirely. The technology is mature, the stablecoin is regulated and audited, and the workflow is not significantly more complex than what you already do.
