## Source summary

CoinDesk reports that Circle launched Arc, a blockchain for payments, tokenized markets, lending and trading. More than 100 institutions and ecosystem companies are participating in or exploring the network; founding validators named in the report include BlackRock, DTCC, ICE, Mastercard, Standard Chartered and Visa. Arc charges transaction fees in USDC, currently uses permissioned validators, and is integrating Circle Payments Network and StableFX for cross-currency settlement.

## Why it matters

This is a reported network launch rather than a roadmap announcement: Circle is putting its payment network, foreign-exchange layer and tokenized-asset infrastructure on one chain. The institutional list includes participants that are live, validating or merely exploring, so it should not be read as uniform production adoption. CoinDesk reports no transaction volume, client revenue, settlement savings, uptime record or independent security audit. Circle says the 10 billion ARC genesis mint is not a commitment to a public token launch, and CoinDesk discloses that its parent company Bullish invested in the earlier token presale.

## Key numbers

- **Institutions and ecosystem companies participating or exploring:** 100+
- **USDC in circulation cited by CoinDesk:** USD 74 billion
- **ARC genesis supply:** 10 billion tokens
- **Earlier ARC token presale:** USD 222 million at a USD 3 billion network valuation

## Topics and entities

- Industry lane: Web3 & stablecoin payments
- Entities: Circle

## Evidence and credibility note

Readable CoinDesk reporting with Circle executive attribution and an explicit disclosure that CoinDesk parent Bullish invested in the ARC presale. The launch and architecture are reported; adoption stages vary and production volume, economics, reliability and security outcomes are not established.

Date evidence: CoinDesk JSON-LD records 2026-09-16T10:30:00.000Z and the readable report says Arc launched on Wednesday, September 16, 2026
