Most people think blockchain payments are already solved.

Move money.
Wait a few minutes.
Call it fast.
But that standard was never built for real financial systems.
Traditional finance settles in days.
Most blockchains settle in minutes.
Both create friction when money is supposed to move like software.
Then there is the second problem nobody talks about:
To use many blockchains, businesses are forced to hold a separate volatile asset just to pay transaction fees.
That might work for speculation.
It doesn't work for treasury management.
@arc approaches the problem differently.
$USDC is the native currency of the network.
You pay with USDC.
You settle with USDC.
You pay gas with USDC.
No separate asset.
No volatility sitting on the balance sheet.
No guessing what operational costs look like next week.
Then comes settlement.
Transactions on Arc reach deterministic finality in under a second.
Once confirmed, they're final.
No challenge periods.
No waiting to see if settlement sticks.
For institutions, speed alone isn't enough.
Financial systems also need confidentiality.
Arc introduces opt-in privacy, allowing sensitive payment information to remain private while preserving auditability and compliance requirements.
Three design choices.
• Dollar-denominated fees
• Sub-second finality
• Compliance-ready privacy
Not crypto infrastructure trying to imitate finance.
Financial infrastructure rebuilt around stablecoins from day one.
