Builder's Map of Agent-Economy Settlement Layers

This article maps four distinct meanings of “settlement” in the emerging agent economy and explains their different trust models and use cases. Meaning 1 is payment-rail settlement (routing a stablecoin to a known seller), exemplified by AEON’s x402 facilitator and recent $8M pre-seed funding. Meaning 2 is micropayment rails for machine-speed, sub-cent transfers, illustrated by Circle’s Nanopayments. Meaning 3 is custodial settlement via trusted vaults, as in Fireblocks’ Agentic Payments Suite. Meaning 4 covers standards and evaluator escrow (e.g., BNBAgent SDK implementing ERC-8183) and a distinct cryptographic atomic settlement primitive using hash-time-locked contracts (HTLCs) for trustless, cross-asset trades. The piece also discusses forward settlement (time-extended atomicity) and the current chain deployment status for cryptographic settlement primitives.

Circle raises $222M in Arc token presale

Circle Internet Group raised $222 million in a presale of Arc, the native token for its new Arc public blockchain, giving the network a fully diluted valuation of $3 billion. Andreessen Horowitz led the round with a $75 million commitment; other participants included BlackRock, Apollo Funds, Intercontinental Exchange, SBI Group, Janus Henderson, Standard Chartered Ventures, General Catalyst, Marshall Wace, ARK Invest, IDG Capital, Haun Ventures and Bullish. Circle will hold 25% of Arc’s initial 10 billion-token supply, 60% will go to network participants and builders, and 15% to a long-term reserve. Circle positions Arc as institutional-grade blockchain infrastructure for finance and unveiled developer tools to build AI agents that transact using USDC. CEO Jeremy Allaire framed the project as an “operating system” for multi-stakeholder financial infrastructure.

Moonshot AI raises $2B at $ $20B valuation

Beijing-based Moonshot AI has raised about $2 billion at a $20 billion valuation in a funding round led by Meituan’s VC arm Long‑Z Investment, with participation from Tsinghua Capital, China Mobile and CPE Yuanfeng, according to a post by Huafeng Capital. The lab, founded in 2023 by Yang Zhilin (a former Meta AI and Google Brain researcher), develops the open-weight Kimi series of large language models; its latest model, Kimi K2.6, is the second-most used LLM on OpenRouter. Huafeng Capital says Moonshot’s annualized recurring revenue topped $200 million in April, driven by paid subscriptions and API usage, and that the company raised $3.9 billion over the past six months. Moonshot’s backers include Alibaba, Tencent, HongShan (Sequoia China), ZhenFund, IDG Capital and 5Y Capital.
