A stablecoin is a digital currency pegged 1:1 to a fiat currency most commonly the US Dollar. Unlike Bitcoin or Ethereum, whose prices fluctuate wildly, stablecoins maintain a constant value: 1 USDC always equals $1.00. For businesses, this stability is what makes stablecoins practical as a payment rail rather than a speculative asset.
The two dominant stablecoins are USDC (issued by Circle, fully regulated and audited) and USDT (issued by Tether). Together they represent over $220 billion in market cap and process more than $10 trillion in quarterly transactions more than Visa and Mastercard combined.
How Do Stablecoins Work?
Every USDC token is backed 1:1 by US dollars or short-term US Treasury bills held in segregated accounts. Circle publishes monthly third-party attestations confirming these reserves. When you send USDC, the transaction is recorded on a public blockchain and settles in seconds no correspondent banks, no SWIFT codes, no cut-off times.
For your business, this means: you hold $10,000 of USDC, you can send exactly $10,000 to a supplier in Singapore tonight at 11pm on a Sunday, and they receive it in under 60 seconds. That scenario is impossible with traditional banking.
Stablecoins vs. Traditional Bank Transfers
Traditional international wire transfers travel through a correspondent banking network often 3–5 intermediary banks each charging fees and introducing delays. SWIFT messages take 2–5 business days to settle, and FX markup adds another 1–3% on top of wire fees. Stablecoins eliminate every intermediary. The transaction goes directly from sender wallet to recipient wallet on a public ledger.
USDC is the only stablecoin that is both fully regulated under US law and operationally available in 185 countries making it the enterprise default for cross-border B2B payments.
Which Stablecoin Should Your Business Use?
For B2B payments, USDC is the clear winner. It is issued under a US money transmitter license, audited monthly by Grant Thornton, and accepted natively by major banking rails, custodians, and payment platforms including Truman, Coinbase, and Circle itself. USDT, while more liquid on digital asset exchanges, lacks the same regulatory transparency and is not MiCA-compliant in the EU as of 2026.
