Getting Started

Arc Network

Arc is an open Layer-1 blockchain developed by Circle — the company behind USDC. It is purpose-built for stablecoin finance, tokenization, and connecting real-world economic activity with on-chain innovation.

Circle describes Arc as the "Economic OS for the internet" — designed to power on-chain lending, capital markets, FX, payments, and tokenized real-world assets. The Arc Testnet launched publicly in late October 2025 and is currently live for developers, enterprises, and builders to deploy and experiment on.

Gas paid in USDC — a unique designUnlike Ethereum (gas in ETH) or most L1 blockchains (volatile native token), Arc uses USDC as its gas token. Transaction costs are predictable in dollar terms. No volatile token to manage. On ArcaneFi, a single asset — USDC — covers gas fees, NFT purchases, platform fees, and mystery box rewards.

Institutional Backing

Arc launched with support from over 100 major institutions across finance, infrastructure, and technology. This gives Arc — and ArcaneFi as its first NFT marketplace — a foundation of institutional credibility that most new blockchains lack entirely.

What Arc is Designed For

Arc's primary focus is stablecoin finance, real-world asset tokenization, and institutional-grade settlements. Announced use cases include on-chain lending, capital markets, FX, cross-chain USDC transfers via Circle's CCTP, and tokenized RWAs.

Being fully EVM-compatible, Arc naturally supports NFT infrastructure, DeFi, and general-purpose smart contracts — which is exactly where ArcaneFi fits. All standard Solidity contracts, Foundry tooling, and Ethereum libraries work on Arc without modification.

Mainnet Status

Arc Mainnet has not launched. Circle has not confirmed a public mainnet date. The current environment is the public testnet, open for all developers and users to participate in.

🔮

Testnet activity & mainnetSome community speculation exists around testnet activity and potential future airdrop eligibility. Circle has not made any official statements about a native token or airdrop programme. Build and use the platform because it is useful — not on speculation.
