Predictability is a feature. Arc makes it the default.

Sub-second finality. Clock-like block cadence. Engineered reliability tested under real-world stress.

Arc is the settlement layer for the internet economy, fast, predictable, and built to last.

[arcDEX | Swap DEX on Arc @arcdex_official]

arcDEX aims to become a foundational market layer within the @arc ecosystem

Supporting traders, liquidity providers, and future financial applications built on Arc.

Looking ahead to 2026.

[Arc @arc]

Arc is built for developers who need reliability, not guesses.

If your app depends on predictable settlement, Arc gives you:
→ Deterministic sub-second finality
→ ~500ms block times by design
→ A stack tuned with chaos-testing and load simulation

This is infrastructure that behaves the same under load as it does under breezy conditions.

Build on a chain engineered for consistency.

[Arc @arc]

This is why we built Arc.

Circle’s 2025 Year in Review is live.

For years we have been building toward an internet financial system where value moves as easily as information. In 2025 that vision came into sharper focus.

→ Global frameworks in the US and beyond advanced, signaling a clear path for fully reserved digital currencies and onchain settlement to move into mainstream use.

→ Circle’s IPO and conditional national trust charter approval reinforced our commitment to transparency, strong governance, and rigorous risk management.

→ Growth of USDC, EURC, and USYC as programmable assets across payments, treasury, FX, and capital markets.

→ How @Arc, the Economic OS for the internet, unites programmable money and onchain innovation with real-world economic activity.

From faster remittances to programmable treasury and near-instant cross-border settlement, these shifts point to an open, more inclusive internet-native financial system.

Speed is not a feature.

Stable fees are not a luxury.

Deterministic settlement is not optional.

arcDEX treats them as the baseline.
