Key features
Arc is purpose-built for real-world economic activity, not general-purpose computation. Each design choice directly supports the needs of financial applications.Stable fee design
Transaction fees are denominated in USDC, so costs stay predictable
regardless of token volatility.
Deterministic finality
Transactions finalize in under one second with no risk of chain
reorganization.
Opt-in privacy
Confidential transfers and selective disclosure for regulated use cases,
available when you need them.
EVM compatibility
Deploy existing Solidity contracts and use standard Ethereum tooling like
Hardhat, Foundry, and Viem.
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, a BFT consensus engine designed for sub-second finality and high throughput. A permissioned validator set provides security and compliance guarantees while keeping the network open for developers and users.
- Execution layer: Runs the EVM, so Solidity contracts, development tools, and wallet infrastructure work without modification.
Stablecoins on Arc
USDC is the native gas token on Arc, so transaction fees are denominated in dollars and you don’t need to hold or manage a separate token to transact. The base fee targets $0.01 per transaction and uses an EIP-1559-style smoothing mechanism to keep costs predictable even under varying network load. Arc also supports EURC for euro-denominated transfers. Both USDC and EURC are available on the Circle Faucet for testnet development, and their contract addresses are listed on the contract addresses page.Network details
