Circle Launches Arc Public Testnet

🚀 Circle Launches Arc Testnet

Arc Testnet Released: Circle launched the Arc public testnet on October 28 as an open Layer-1 blockchain designed for internet-scale finance. It features predictable dollar-based fees, sub-second finality, opt-in privacy, and integration with Circle’s platform. Over 100 institutions across finance and tech are testing use cases in payments, lending, and capital markets. Jeremy Allaire, Circle CEO, stated: “With Arc’s public testnet, we’re seeing remarkable early momentum as leading companies begin to build and test.” The network supports USDC, which represents $76 billion of the $292 billion in circulating USD stablecoins.

Institutional Participants: Participants include BlackRock, Visa, Goldman Sachs, Deutsche Bank, BNY Mellon, HSBC, Mastercard, and Anthropic. Capital market firms like Apollo and ICE are upgrading equity and custody systems. Stablecoin issuers from seven countries (Australia, Brazil, Japan, South Korea, Mexico, Philippines, Canada) are testing local fiat tokens. Developer support comes from Alchemy, Chainlink, and MetaMask. Robert Mitchnick, BlackRock’s Head of Digital Assets, said: “As the digital asset ecosystem evolves, we believe tokenization can unlock additional utility for onchain assets.”

Competitor Context: Stripe-backed Tempo, a similar payments-focused Layer 1, recently raised $500 million at a $5 billion valuation on October 17. Led by Paradigm’s Matt Huang, it includes partners like Visa, Anthropic, and Deutsche Bank. Ethereum researcher Dankrad Feist joined Tempo while remaining an Ethereum advisor. Stripe CEO Patrick Collison described Tempo as “the payments-oriented L1, optimized for real-world financial-services applications.” Both networks target institutional on-chain finance, with Arc now live in testnet and Tempo’s mainnet timeline undisclosed.

☁️ EigenCloud: Verifiable Cloud & Ethereum Restaking

☁️ What is EigenCloud EigenCloud is a developer platform built on EigenLayer, Ethereum’s leading restaking protocol. Users restake ETH or EIGEN to secure DeFi, AI, and real-world applications. With over $20B in TVL and 162+ Actively Validated Services (AVSs) in development, it’s backed by a16z’s recent $170M investment. Join now: Restake to earn rewards (over $128M already distributed) or run nodes for AI inference and scaling. Just launched: Concrete’s Staked Eigen Vault delivers 8-10% real USD yield, Eigen incentives, partner rewards, and full DeFi composability.

📊 a16z State of Crypto 2025 Report In its latest State of Crypto report, a16z highlights the convergence of global infrastructure scaling, institutional adoption, and AI’s need for verifiable compute. EigenLayer now holds 10% of all DeFi TVL, more than any chain outside Ethereum. EigenCloud stands out as the full-stack solution for trusted AI agents, offering secure inference, compute, and data availability with deep liquidity and economic security. This makes restaking a foundational layer for agentic finance and autonomous systems.

🚀 EIGEN & x402: Early in the Stack Long before x402 became the standard for agent-to-agent (A2A) payments, EigenCloud shipped live verifiable workflows with Google’s AP2 in September. EigenCompute executes tasks with cryptographic proofs, EigenDA provides scalable storage for inputs and outputs across chains, and AVSs integrate trust directly into agent operations. Together, the x402 + AP2 + EigenCloud stack forms a complete verifiability layer, enabling secure, programmable interactions in the emerging agent economy.
