The brief

Analyst view
  • NYSE IPO on 5 June 2025. The GENIUS Act set US federal stablecoin rules the next month.
  • Arc mainnet launched 16 Sept 2026 with USDC for fees. BlackRock and Visa are among its first validators.
  • CCTP moves USDC between chains by destroying it on one and creating it on the other, with no wrapped copies.

Technical approach

As reported
Reserves

Fully backed by cash and T-bills

Each USDC can be redeemed for $1. Reserves sit mostly in a SEC-registered money market fund, with monthly outside checks.

Interop

CCTP burn-and-mint

USDC is destroyed on one chain, Circle signs off, and new USDC is created on the other. No bridge holds a pile of coins.

Arc consensus

Malachite

A Tendermint-style voting engine written in Rust. Blocks are final in under a second. Validators are pre-approved at launch.

Arc design

Dollar fees, optional privacy

Fees are paid in USDC, so costs are predictable. Arc runs Ethereum-style apps and offers optional privacy for institutions.

Open technical problems

Open · Active · Partial
  • Interest-rate sensitivityOpen

    Most revenue is interest on reserves, which falls as rates fall. A large share is paid out to distribution partners.

  • Neutrality of an issuer-run chainOpen

    Arc must convince other stablecoin issuers and apps that a Circle-run chain treats them fairly.
