Build and deploy smart contracts that demonstrate advanced programmable logic using USDC or EURC — such as conditional flows, onchain automation, or multi-step settlement mechanisms. What we’re looking for: - Conditional escrow with onchain dispute + automatic release - Programmable payroll / vesting in USDC or EURC - Crosschain “conditional transfer” (escrow on source, release on destination via Circle Forwarder)

Build chain abstracted USDC apps that treat multiple blockchains as one liquidity surface, using Arc to move USDC wherever it’s needed. Projects should demonstrate how capital can be sourced, routed, and settled across chains through a single application without fragmenting user experience. What we’re looking for: -Crosschain payments, credit, or treasury systems -Applications that are not locked to a single chain -Seamless user experience despite crosschain complexity"

Build applications that enable autonomous AI agents to transact with each other using nanopayments on Arc. Projects should demonstrate how agents can make gas-free micropayments for API calls, data access, compute resources, or services without human intervention. Focus on agent-to-agent commerce, automated payment flows, and scalable transaction systems where traditional payment rails are too expensive or slow. Examples: - AI agents paying for API calls, LLM inference, or data access per-use - Autonomous agents trading services or compute resources - Multi-agent systems with payment-based coordination mechanisms - Agent marketplaces with gas-free microtransactions - Pay-per-query knowledge bases or RAG systems accessed by agents - Automated content monetization (pay $0.01 per article/video)

Build prediction market applications on Arc that move beyond speculation and deliver real-world utility — such as forecasting, hedging, and decision-making. Projects should leverage Arc’s stablecoin-native infrastructure (USDC/EURC gas, native FX, deterministic finality, and compliance-ready architecture) to create prediction markets that are easier to use, economically predictable, and credible enough for consumer, institutional, and enterprise use cases. Please see resources section for recommended products to use Examples: Macroeconomic data markets — Markets on CPI, Fed decisions, jobs, GDP → Short-duration, high-frequency demand • Geopolitical & event-driven markets — Markets on elections, conflicts, trade, energy shocks → Direct pricing of real-world uncertainty • Institutional hedging markets — Onchain tools for macro + geopolitical risk → Simpler, more direct than derivatives • Multi-currency / localized markets — Region-specific markets (EURC, USDC, etc.) → Native FX + localized settlement • Governance & enterprise forecasting — Markets for internal decisions, policy, planning → Enabled by identity, compliance, auditability
