Circle Launches Arc Mainnet: Institutional Validators, USDC Gas, and Early Memecoin Activity
By Drooid · · How we work
Core Event – Public Mainnet Activation
On September 16 Circle opened the Arc mainnet to the public. The permissioned Proof-of-Authority validator set includes eleven founding institutions—BlackRock, DTCC, Visa, Mastercard, Standard Chartered, ICE, Galaxy, MoneyGram, SBI Group, Sumitomo Corporation, and Global Payments. Arc uses USDC as the native gas asset, so fees are quoted and paid in dollars, delivering deterministic sub-second finality.
Background & Context
Arc was unveiled in August 2025 for stablecoin payments, tokenized assets, and AI-driven transactions. A public testnet launched in October 2025 and, by June 30, processed more than 700 million transactions and recorded 2.8 million wallets, according to Circle’s second-quarter SEC filing. At genesis, Circle minted 10 billion ARC tokens; the mint is a technical step rather than a public token offering.
Data & Statistics
- ARC supply: 10 billion tokens minted at launch.
- Private sales: 807.5 million ARC for $242.2 million (source: Circle) and 740 million ARC for $222 million at a $3 billion valuation (source: Circle).
- Testnet activity: >700 million transactions; 2.8 million wallets (as of June 30).
- Ecosystem builders: >190 institutional participants; >100 applications live or under exploration.
- USDC ecosystem: $74 billion in circulation; USDC accounts for 98.8 % of agent-driven transaction volume on Arc.
- Early fee generation: Pons launchpad collected $5.95 million in fees in the first 24 hours to September 3.
Official Statements & Responses
BlackRock’s global head of digital assets, Robbie Mitchnick, said purpose-built blockchains can accelerate digital-asset use cases and positioned Arc as well-suited for stablecoin and payment workloads at scale. The DTCC indicated plans to begin tokenizing DTC-custodied assets on Arc in the second half of 2027.
On-the-Ground Reports – Early Memecoin Activity
The first day of mainnet operation saw memecoin launchpads such as Bullcheese and Pons deploying new tokens. Bullcheese locks a one-billion-unit supply in a Uniswap v3 liquidity position, charging a 1 % swap fee with 75 % paid to creators in USDC. Pons reported $5.95 million in fees within its initial 24-hour window, illustrating how Arc’s USDC-denominated fees enable creators to receive “actual dollars” rather than volatile crypto assets.
Why It Matters / Impact
Arc’s design eliminates the need to hold a separate volatile network token, allowing treasury teams to forecast costs in fiat terms. Deterministic sub-second settlement aligns with capital-market latency requirements. Integration with Circle’s services—StableFX, Arc Studio, and the Arc App Kits—provides a ready-to-use stack for tokenized assets, AI agents, and cross-chain USDC transfers. Participation of major banks and custodians signals a shift toward permissioned, finance-grade blockchains for mainstream operations.
Conflicting Reports & Gaps
Sources differ on the volume and valuation of private ARC sales. One report cites 807.5 million ARC sold for $242.2 million, while another notes a May 2026 sale of 740 million ARC for $222 million at a $3 billion valuation. Both figures are private transactions, and no public market for ARC has been established. Clarification from Circle on final token allocation and any future listing plans remains pending.
