BlackRock, DTCC, Intercontinental Exchange, Mastercard, Standard Chartered and Visa are among Arc’s founding validators, while BNY, HSBC and State Street are some of the 100+ institutions and ecosystem companies live on or exploring the network.
Trading venues on Arc include Uniswap and Aerodrome, while Aave and Morpho are providing lending markets. Tokenized money market funds including Circle’s USYC and BlackRock’s BUIDL are also coming to the network.
Allaire called Arc a “canonical home for asset issuers,” where funds, equities, commodities and currencies could be issued before moving to other blockchain ecosystems through Circle’s interoperability infrastructure.
Circle Payments Network is also being integrated directly into Arc alongside StableFX, its foreign-exchange platform for 24/7 cross-currency settlement.
Arc was designed around some of the friction that has kept traditional financial institutions from using existing blockchains, Allaire said.
Circle is developing configurable privacy for institutions that need to shield transaction data while retaining access for auditors and regulators.
Transaction fees are paid in USDC rather than a volatile native token, with sub-second finality and a permissioned validator set.
Balancing act
Allaire compared requiring companies to hold a blockchain’s native token just to use the network with making Netflix buy Amazon shares to pay its Amazon Web Service bill.
