In brief
- Circle has announced the launch of StableFX and Circle Partner Stablecoins to create a unified infrastructure stack for institutional FX activity.
- StableFX features on-chain settlement with simultaneous payment and delivery, eliminating counterparty risk through 24/7 trading.
- Eight regional stablecoin issuers gain integration into Circle’s Payments Network, expanding beyond domestic markets.
USDC stablecoin issuer Circle has launched Circle StableFX, an institutional-grade foreign exchange engine that enables 24/7 stablecoin currency pair trading with on-chain settlement on its Arc blockchain network.
The company simultaneously announced Circle Partner Stablecoins, a program supporting select regional stablecoin deployments on Arc, creating a unified infrastructure stack for global FX activity, according to a press release shared with Decrypt.
The dual offerings is built on Arc’s Layer-1 blockchain, whose public testnet went live last month with over 100 participants, including BlackRock, Visa, Goldman Sachs, Deutsche Bank, Standard Chartered, BNY, State Street, ICE, AWS, Cloudflare, Mastercard, Coinbase, Kraken, Robinhood, and others.
The initiative targets inefficiencies in the foreign exchange market, which still operates on fragmented venues, prefunded accounts, and T+1 settlement cycles.
T+1 settlement means when you trade an asset, the actual transfer of money and ownership happens the next business day, not immediately.
By combining Arc’s programmable settlement infrastructure with stablecoin-powered trading, Circle seeks to enable real-time cross-border currency exchange with reduced counterparty risk and capital requirements.
“With StableFX and Circle Partner Stablecoins, we’re connecting the world’s currencies on Arc,” Circle Chief Product and Technology Officer Nikhil Chandhok said in the press release.
The announcement follows Circle’s strong third-quarter performance, with the company reporting $740 million in revenue and reserve income, surpassing analyst forecasts by 66% year over year.
USDC’s market capitalization has risen from $61 billion at Circle’s June IPO to over $76 billion, according to CoinGecko, still trailing Tether’s USDT, which tops $184 billion.
How StableFX works
StableFX operates through a request-for-quote execution model connecting institutions with multiple liquidity providers, offering competitive pricing with low slippage.
The platform features on-chain settlement, where both payment and delivery occur simultaneously, eliminating the risk that one party fails to deliver funds after receiving the counterparty’s currency.
The all-to-all model removes the need for bilateral agreements with multiple counterparties.
Currently live on Arc testnet, StableFX is available for approved institutions that have completed Know-Your-Business and Anti-Money Laundering verification ahead of Arc’s planned 2026 mainnet launch.
Arc uses USDC for transaction fees, features sub-second finality, and includes opt-in privacy configurations designed for institutional compliance requirements.
During the testnet launch, Circle CEO Jeremy Allaire said the project has shown “remarkable early momentum,” with the firm noting in its Q3 report that it’s exploring the possibility of a native Arc token.
Regional stablecoin partnerships
Circle Partner Stablecoins targets non-USD-pegged stablecoin issuers meeting technical, operational, and reserve management standards.
Initial participants include Avenia (Brazilian real), Forte (Australian dollar), JYPC (Japanese yen), Juno (Mexican peso), Busan Digital Asset Custody Services (South Korean won), Stablecorp (Canadian dollar), Luno (South African rand), and Coins.ph (Philippine peso).
These stablecoins gain integration into Circle’s Payments Network and StableFX, expanding utility beyond domestic markets.
