Arc, an open Layer-1 network built for the world's financial markets, is live on mainnet. Our full developer platform is live for all Arc builders on day one, with support for RPC, WebSockets, Data APIs, Wallet APIs, and gasless transaction infrastructure.

What is Arc

Arc is an open, EVM-compatible Layer-1 built for real-time money movement and agentic economic activity. It uses stablecoins as gas, starting with USDC, and targets deterministic sub-second finality with predictable, dollar-based fees. From launch, Arc carries live markets for lending, borrowing, trading, onchain FX, payments, and tokenized assets.

Arc also takes a unique approach to security with Arc's founding validators as regulated banks, payment networks, custodians, and financial infrastructure providers, including BlackRock, DTCC, Mastercard, Standard Chartered, and Visa. In practice, that means the same kinds of institutions moving money across Arc are also the ones confirming its transactions, spread across a geographically diverse set of operators.

How Alchemy supports Arc

We provide Day 1 infrastructure for Arc across our full developer platform.

Node RPC APIs and WebSockets for industry-leading reliability and low-latency requests.

Data APIs give teams indexed access to balances, transactions, and asset activity.

Wallet APIs and gasless transaction infrastructure let teams sponsor gas fees so users can transact without holding a separate gas token.

Arc builders can leverage all of it to build seamless end-to-end financial experiences, backed by infrastructure processing $1T+ in transactions a year, at 99.99% uptime and SOC 2 Type II compliance.
