Circle positions Arc as infrastructure for internet-native finance

Arc Mainnet, AI Agents, and Tokenized Markets | Nikhil Chandhok, CTO of Circle

Arc’s design shows how stablecoin settlement could move beyond payments into institutional markets, agentic commerce, and global financial infrastructure.

3 key takeaways

1Arc combines permissioned validators with permissionless application deployment to balance control, openness, and institutional usability.
2Circle frames Arc as settlement infrastructure for new markets, not simply another venue for existing Ethereum-based DeFi activity.
3Agentic commerce and tokenized equities depend on reliable on-chain settlement, while privacy, reversibility, and security remain unresolved tradeoffs.

Don't miss

Nikhil Chandhok reframes agentic commerce as a settlement problem, describing agents that can trade on-chain and purchase goods or services.

The brief

Circle CTO Nikhil Chandhok presents Arc Mainnet as an economic operating system: stablecoin-based infrastructure designed for fast settlement and institutional financial applications.

Arc pairs a permissioned validator set with permissionless contract deployment and interaction, a compromise meant to provide institutional control without closing the application layer.

The privacy design relies on trusted execution environments, exposing a central tension between confidential transactions, security assumptions, and the ideal of immutable public infrastructure.

Chandhok argues Arc should expand the market rather than merely pull activity from Ethereum, with exchanges, lending protocols, asset issuers, and AMMs building around USDC settlement.

The conversation’s sharpest turn comes when agentic commerce moves from buzzword to infrastructure question: agents may buy goods, trade on-chain, and require financial rails built for automated actors.

Tokenized equities and global stablecoins extend the same thesis, positioning Arc as the settlement layer beneath applications, exchanges, and a potential internet-native FX system.
