Circle Launches Arc Blockchain to Bridge Finance and Crypto

Circle just unveiled a new blockchain called Arc, marking its boldest move outside the massive USDC stablecoin world. The launch signals the company is stepping up its game as more firms race to build financial rails onchain. Jeremy Allaire, Circle chief, called the moment a turning point, even bigger than the USDC debut itself. He sees Arc as a general-purpose economic operating system for payments, tokenized markets, lending, and trading. This shift shows Circle wants to do more than just issue digital dollars and settle payments on a single network.

What makes Arc stand out is who is already on board. Heavy hitters like BlackRock, Visa, Mastercard, and Intercontinental Exchange are founding validators, joining a growing list of over a hundred institutions already exploring the network. Trading venues such as Uniswap and Aerodrome are live, while lending markets like Aave and Morpho are also part of the network. Tokenized money market funds, including Circle USYC and BlackRock BUIDL, are ready to move onto the chain. The lineup shows traditional finance is testing the waters alongside crypto natives and startups.

Arc was built to solve a key problem: traditional finance shies away from blockchains that demand volatile native tokens for fees. Allaire joked that making Netflix pay Amazon Web Services bills with Amazon shares would be crazy. Arc still has its own network token, but fees are paid in USDC, the stablecoin, offering sub-second finality. The network currently runs on proof of authority, with plans to shift to proof of stake by 2027, which could give the ARC token a role in security and governance. This approach makes Arc more palatable for banks and established firms looking to experiment with onchain finance.

In a strategic move, Circle is keeping its digital assets widely available across popular platforms, much like Google products on rival systems. The company raised 222 million dollars in a presale earlier this year, valuing the network at 3 billion dollars, with backers including Apollo Funds and ARK Invest. Arc creates a new balancing act for Circle, which built USDC by distributing it across many competing networks. The goal is to ensure Circle apps and assets remain accessible everywhere. Circle says the 10 billion ARC tokens minted at launch are not yet for public sale, but the network is live for participating institutions.
