# Arc in numbers

Arc is the layer-1 blockchain built by Circle. Generated 26 Oct 2026, 10:12 UTC; each figure gives its source and date.

## Facts

- Circle launched the public Arc mainnet on 16 September 2026, after a private mainnet phase. ([source](https://www.circle.com/pressroom/circle-launches-arc-mainnet-an-economic-operating-system-for-the-internet), 16 Sep 2026)
- USDC is Arc's native gas token. The native gas balance uses 18 decimals; the USDC ERC-20 interface at 0x3600…0000 uses 6 decimals. ([source](https://docs.arc.io/arc/references/contract-addresses), 16 Sep 2026)
- Arc is EVM-compatible and targets Ethereum's Osaka hard fork as its baseline, including EIP-7702. ([source](https://docs.arc.io/arc/references/evm-differences), 16 Sep 2026)
- Along with Circle, Arc's founding validators include BlackRock, DTCC, Galaxy, ICE, Mastercard, MoneyGram, SBI Group, Standard Chartered, Sumitomo Corporation, Visa and Worldpay, in a phased rollout. ([source](https://www.circle.com/pressroom/circle-launches-arc-mainnet-an-economic-operating-system-for-the-internet), 16 Sep 2026)
- Arc's consensus uses Malachite, a Tendermint BFT implementation, with a permissioned proof-of-authority validator set. ([source](https://docs.arc.io/arc/concepts/consensus-layer), 16 Sep 2026)
- Circle said the network is exploring a future transition from proof of authority toward proof of stake in 2027. ([source](https://www.circle.com/pressroom/circle-launches-arc-mainnet-an-economic-operating-system-for-the-internet), 16 Sep 2026)
- Circle completed the genesis mint of the ARC token, its full initial supply of 10 billion; it said this is not a commitment to publicly launch ARC, and fees remain payable in USDC. ([source](https://www.circle.com/pressroom/circle-launches-arc-mainnet-an-economic-operating-system-for-the-internet), 16 Sep 2026)
- Arc held 969,016,778 USDC on 26 Oct 2026, 10:12 UTC. (Arc RPC)
- TVL on Arc was $628,928,070 on 26 Oct 2026. (DefiLlama)
- About 514,000 transactions in the last 24 h, estimated from 240 sampled blocks. (Arc RPC) (i: Blocks 27,779,107 to 27,948,845, evenly spaced; the mean count per sampled block times the blocks in 24 h, rounded to the nearest 1,000.)
- Apps tracked by Registrai received $18,420,057 in USDC payments in the last 24 h. (Arc Ecosystem Index)
