BENEFITS & FEATURES OF ONCHAIN FX

FX settlement without constraints

Circle combines infrastructure, stablecoins, and institutional-grade applications into one complete onchain FX solution.

Trade on your own schedule

For many currency pairs, banking hours barely overlap. Onchain FX settles 24/7, so time zones never delay your timeline.

Eliminate principal risk

Payment-vs-payment settlement can be built on Arc, a layer-1 blockchain developed by Circle, ensuring that both sides settle or neither does.

Free up trapped capital

Prefunding accounts across currencies ties up capital before a trade executes. Onchain FX reduces that need.

Access new corridors

Many corridors are poorly served by traditional rails. Onchain FX opens markets underserved by legacy infrastructure.

INTRADAY LIQUIDITY MANAGEMENT FOR BANKS

Execute and unwind FX swaps intraday at any hour

Banks need fast access to a currency to meet intraday liquidity requirements. Circle Mint converts fiat into EURC and USDC, StableFX settles both legs simultaneously on Arc, and the bank unwinds positions before markets close.

CROSS-BORDER B2B PAYMENTS

Deliver instant local currency payouts to global suppliers

When supplier invoices are due, StableFX quotes competitive rates across multiple liquidity providers. Transactions settle into local currency stablecoins atomically on Arc, delivering fast, transparent payouts to global partners.

EMERGING MARKET PAYROLL

Pay workers in local currency from one USDC balance
