**Streampay** is a programmable, linear payment protocol built on the **Arc Network**. It allows you to send money (specifically **USDC**) over a fixed period of time, where the balance "unlocks" and becomes available to the recipient every second, rather than in one lump sum. ### ## **How it Works** * **Continuous Flow:** Instead of waiting for the end of the month, a recipient sees their balance tick up in real-time (e.g., at 100ms intervals). * **Gasless Claims:** Leveraging the **Hash PayLink** relayer, recipients can withdraw their unlocked funds to their wallet for **$0 gas** by simply signing a message. * **On-Chain Security:** Funds are held in a secure, audited **StreamVault** smart contract. The sender can cancel the stream at any time to refund unearned funds, while the recipient can withdraw what they’ve earned whenever they want. Stateless Invoicing: Every stream has a unique URL that contains the "Reason for Stream" (like "April Salary" or "Freelance Gig"), making it a self-contained, transparent financial agreement. Core Use Cases Web3 Payroll: Pay contributors and employees by the second. * **Vesting:** Automate token or stablecoin releases for founders and investors. * **Subscriptions:** Stream payments for services as they are consumed. * **Freelance Escrow:** Build trust by letting clients see the money "earning" as work progresses.

In this hybrid hackathon powered by Arc and Circle, developers will build the next generation of Agentic economic applications using Circle’s Nanopayments infrastructure with settlement on Arc in USDC. For the first time, high-frequency, usage-based transactions between users, APIs, and AI agents can operate without gas overhead eroding margin. Arc provides stablecoin-native settlement with predictable, dollar-denominated USDC fees and deterministic, sub-second finality — enabling real-time coordination and economically viable per-action pricing at scale. 📅 April 20 – 26, 2026 • Apr 20 – 25 (Online): Submit projects by Apr 25. • Apr 25 (On-site Build – SF, CA): Teams refine projects. • Apr 26 (On-site Demos & Awards – SF, CA): Live pitches & winners announced.
