The internet gave us standards for information and communication. The next phase is building standards for money and identity. @jerallaire on why AI and blockchain based financial infrastructure are accelerating the need for internet native identity systems.

EURC wallet share grew more than 6x from January 2025 to March 2026. As adoption expands, euro-denominated stablecoin usage is reaching a broader set of users and applications onchain.

Jeremy Allaire (@jerallaire) is the Chairman, CEO, and co-founder of @circle, the issuer of USDC — a stablecoin with nearly $80 billion in circulation and a core piece of the broader stablecoin market, which has grown from zero to more than $300 billion over the past decade. In this fireside, YC Visiting Partner @nemild sat down with Jeremy to talk about Circle's founding vision of building an internet protocol for dollars, the wave of institutional and regulatory adoption now reshaping the financial system, and why agentic economic activity, not just consumer payments, might represent the most transformative frontier for stablecoin builders in the years ahead. 00:00 - Why Stablecoins Matter 01:45 - Circle's Origin 07:10 - Top Use Cases for Builders Today 11:22 - Consumer vs. Business Adoption 13:20 - Banks & Institutions Enter the Space 17:54 - Global Regulation Landscape 22:40 - AI Agents & the Agentic Economy 26:15 - Missing Infrastructure for Builders 27:38 - Three Big Predictions for Stablecoins

Circle Current Session Recap: Always-On Settlement Rewrites the Bank Operating Model Circle Current is a series from Circle that brings together industry leaders to explore what’s next in the internet financial system. Always-on settlement is moving from pilot to production, with stablecoin rails giving banks a practical path to move funds 24/7. What’s changing: → Settlement is moving beyond banking hours → Liquidity can move with less delay → Prefunding requirements can start to shrink → Treasury and operations teams need to adapt to continuous money movement Visa’s rollout shows this is no longer an edge case. For banks, the shift is bigger than faster payments. It is an operating model change. Read the blog for more details:

An agent with funds still needs trusted services it can pay for to complete its tasks. Agent Marketplace gives users and agents a structured place to discover, evaluate, and integrate agentic services. That moves service access closer to usage-based, programmable economic activity. Part of Circle Agent Stack:

USYC’s growth reflects the expanding role of tokenized real-world assets in capital markets. Circle’s tokenized money market fund is becoming a key building block for onchain collateral.

HIP-4 introduces outcome-based markets to @HyperliquidX — new primitives for onchain trading. Circle is becoming the technical deployer of USDC as an Aligned Quote Asset (AQA). What matters is how liquidity, capital, and settlement coordinate across these systems — with native crosschain infrastructure enabling how capital moves. From trading to nanopayments, this is programmable money moving into more complex market structures.

New market structures are going onchain.  USDC is a foundational layer for liquidity, collateral, and quoting on @HyperliquidX. Open, interoperable and programmable digital dollars will power the future of all of finance. Hyperliquid.

USDC is becoming a core part of @HyperliquidX’s evolving market structure. USDC will become an Aligned Quote Asset on Hyperliquid and continue as the primary collateral asset across HIP-1, HIP-2, HIP-3, and now HIP-4 markets. As Hyperliquid expands into new onchain markets, USDC enables: → Deep liquidity across trading pairs → Greater capital efficiency ecosystem-wide → Seamless crosschain access to digital dollars Circle is also making a significant financial investment in the ecosystem through HYPE staking.

As AI agents take on more work across information, data, and coordination, financial infrastructure has to evolve with them. @jerallaire speaks on why AI operating systems and economic operating systems will need to work together at @Abundance360.

Agents need access to funds. Users need control. Agent Wallets give agents a way to hold and move USDC under human-defined policies, including: → Time-bound spending limits → Transfer and x402 service controls → Allowlists and blocklists → Wallet-layer policy enforcement Built for agentic payments with guardrails.

Circle Gateway now supports webhooks. Developers can receive real-time notifications for key lifecycle events like deposits, forwarded messages, and mints directly in their backend, instead of relying on polling. → React to deposit finalized events without constant polling → Trigger backend workflows when state changes happen → Build cleaner event-driven crosschain flows Start building:

Circle Agent Stack is infrastructure for the agentic economy. In this demo, watch an agent: → Create a wallet funded with USDC → Discover services in Agent Marketplace → Pay for API access through Circle Gateway → Execute financial actions with Circle CLI Built for developers creating agent systems with defined permissions and guardrails.
