# Arc

> The Economic OS for the internet

Arc is a stablecoin-native Layer 1 blockchain for payments, foreign exchange, and tokenized asset settlement. It serves financial institutions and developers with dollar-denominated fees, sub-second deterministic finality, and opt-in privacy.

Arc is a stablecoin-native Layer 1 blockchain designed as a settlement layer for real-world financial activity. Transaction fees are paid in a dollar stablecoin rather than a volatile native token. The network targets payments, foreign exchange, tokenized asset issuance, and automated economic activity between software agents.

Arc addresses the cost volatility and settlement uncertainty that limit general-purpose blockchains in regulated financial workflows. It runs a Byzantine fault tolerant consensus protocol delivering deterministic finality in under a second, paired with an EVM-compatible execution layer so existing smart contracts and developer tooling carry over. A permissioned validator set of market infrastructure operators, banks, and card networks secures it, with opt-in privacy controls that shield transaction detail while preserving auditability.

The network connects to wider stablecoin and tokenized asset liquidity through cross-chain transfer infrastructure, letting teams anchor settlement, collateral, and treasury workflows on Arc. Applications span lending and borrowing markets, onchain foreign exchange, prediction markets, and cross-border payouts. Arc is used by developers, fintech companies, payment providers, and financial institutions building stablecoin-native applications.
