Key features
Stablecoin native model
USDC is the native gas token. EURC and USYC are natively supported. No
volatile token required.
Stable fee design
Transaction fees are denominated in USDC, so costs stay predictable
regardless of market volatility.
Deterministic finality
Transactions finalize in under one second with no risk of chain
reorganization.
EVM compatibility
Deploy existing Solidity contracts and use standard Ethereum tooling like
Hardhat, Foundry, and Viem.
Opt-in privacy
Run Solidity contracts confidentially in ArcaneVM, an opt-in execution
environment that finalizes alongside the public EVM.
Post-quantum security
SLH-DSA-SHA2-128s wallet signatures protect accounts against future quantum
threats.
Stablecoins on Arc
Arc is designed from the ground up around stablecoins. USDC serves as the native gas token, EURC enables euro-denominated transfers, and USYC provides onchain yield. There is no volatile native token. For details on the dual-interface model, native representations, and supported assets, see stablecoin native model.Network architecture
Arc separates consensus from execution so each layer can optimize independently while maintaining full compatibility with the Ethereum ecosystem.- Consensus layer: Built on Malachite BFT, delivering sub-second finality and high throughput across a permissioned validator set.
- Execution layer: Powered by Reth, a Rust Ethereum client that runs the EVM so Solidity contracts, development tools, and wallet infrastructure work without modification.
